“Mr. Ayscough!” said Melky. “I hadn’t a notion of aught like that–it’s give me a turn! But don’t I know what it means, Mr. Ayscough–not half! It’s all of a piece with the rest of it! Murder, Mr. Ayscough–bloody murder! All on account of that orange-yellow diamond we’ve heard of–at last. Ah!–if I’d known there was that at the bottom of this affair, I’d ha’ been a bit sharper in coming to conclusions, I would so! Diamond worth eighty thousand pounds–.”

Ayscough, who had been busy at the front door of the house, suddenly interrupted his companion’s reflections.

“The door’s open!” he exclaimed. “Open! Not even on the latch. Come on!”

Melky shrank back at the prospect of the unlighted hall. There was a horror in the garden, in that bright moonlight–what might there not be in that black, silent house?

“Well, turn that there bull’s eye on!” he said. “I don’t half fancy this sort of exploration. We’d ought to have had revolvers, you know.”

Ayscough turned on the light and advanced into the hall. There was nothing there beyond what one would expect to see in the hall of a well-furnished house, nor was there anything but good furniture, soft carpets, and old pictures to look at in the first room into which he and Melky glanced. But in the room behind there were evidences of recent occupation–a supper- table was laid: there was food on it, a cold fowl, a tongue–one plate had portions of both these viands laid on it, with a knife and fork crossed above them; on another plate close by, a slice of bread lay, broken and crumbled–all the evidences showed that supper had been laid for two, that only one had sat down to it: that he had been interrupted at the very beginning of his meal–a glass half-full of a light French wine stood near the pushed-aside plate.

“Looks as if one of ’em had been having a meal, had had to leave it, and had never come back to it,” remarked Ayscough. “Him outside, no doubt. Let’s see the other rooms.”

There was nothing to see beyond what they would have expected to see– except that in one of the bedrooms, in a drawer pulled out from a dressing-table and left open, lay a quantity of silver and copper, with here and there a gold coin shining amongst it. Ayscough made a significant motion of his head at the sight.

“Another proof of–hurry!” he said. “Somebody’s cleared out of this place about as quick as he could! Money left lying about–unfinished meal–door open–all sure indications. Well, we’ve seen enough for the present. Our people’ll make a thorough search later. Come downstairs again.”

Neither Ayscough nor Melky were greatly inclined for conversation or speculation, and they waited in silence near the gate, both thinking of the still figure lying behind the laurel bushes until the police came. Then followed whispered consultations between Ayscough and the inspector, and arrangements for the removal of the dead man to the mortuary and the guardianship and thorough search of the house–and that done, Ayscough beckoned Melky out into the road.

“Glad to be out of that–for this time, anyway!” he said, with an air of relief. “There’s too much atmosphere of murder and mystery–what they call Oriental mystery–for me in there, Mr. Rubinstein! Now then, there’s something we can do, at once. Did I understand you to say these two were medical students at University College?”

“So Mr. Penniket said,” replied Melky. “S’elp me! I never heard of ’em till this afternoon!”

“You’re going to hear a fine lot about ’em before long, anyway!” remarked Ayscough.

“Well–we’ll just drive on to Gower Street–somebody’ll know something about ’em there, I reckon.”

He walked forward until he came to the cab-rank at the foot of St. John’s Wood Road, where he bundled Melky into a taxi-cab, and bade the driver get away to University College Hospital at his best pace. There was little delay in carrying out that order, but it was not such an easy task on arrival at their destination to find any one who could give Ayscough the information he wanted. At last, after they had waited some time in a reception room a young member of the house-staff came in and looked an enquiry.

“What is it you want to know about these two Chinese students?” he asked a little impatiently, with a glance at Ayscough’s card. “Is anything wrong?”

“I want to know a good deal!” answered Ayscough. “If not just now, later. You know the two men I mean–Chang Li and Chen Li–brothers, I take it?”

“I know them–they’ve been students here since about last Christmas,” answered the young surgeon. “As a matter of fact they’re not brothers– though they’re very much alike, and both have the same surname–if Li is a surname. They’re friends–not brothers, so they told us.”

“When did you see them last?” asked Ayscough.

“Not for some days, now you mention it,” replied the surgeon. “Several days. I was remarking on that today–I missed them from a class.”

“You say they’re very much alike,” remarked the detective. “I suppose you can tell one from the other?”

“Of course! But–what is this? I see you’re a detective sergeant. Are they in any bother–trouble?”

“The fact of the case,” answered Ayscough, “is just this–one of them’s lying dead at our mortuary, and I shall be much obliged if you’ll step into my cab outside and come and identify him. Listen–it’s a case of murder!”

Twenty minutes later, Ayscough, leading the young house-surgeon into a grim and silent room, turned aside the sheet from a yellow face.

“Which one of ’em is it?” he asked.

The house-surgeon started as he saw the wound in the dead man’s throat.

“This is Chen!” he answered.

CHAPTER TWENTY-EIGHT

THE L500 BANK NOTE

Ayscough drew the sheet over the dead man’s face and signed to his companion to follow him outside, to a room where Melky Rubinstein, still gravely meditating over the events of the evening, was awaiting their reappearance.

“So that,” said Ayscough, jerking his thumb in the direction of the mortuary, “that’s Chen Li! You’re certain?” “Chen Li! without a doubt!” answered the house-surgeon. “I know him well!”

“The younger of the two?” suggested Ayscough.

The house-surgeon shook his head.

“I can’t say as to that,” he answered. “It would be difficult to tell which of two Chinese, of about the same age, was the older. But that’s Chen. He and the other, Chang Li, are very much alike, but Chen was a somewhat smaller and shorter man.”

“What do you know of them?” inquired Ayscough. “Can you say what’s known at your hospital?”

“Very little,” replied the house-surgeon. “They entered, as students there–we have several foreigners–about last Christmas–perhaps at the New Year. All that I know of them is that they were like most Easterns– very quiet, unassuming, inoffensive fellows, very assiduous in their studies and duties, never giving any trouble, and very punctual in their attendance.”

“And, you say, they haven’t been seen at the hospital for some days?” continued Ayscough. “Now, can you tell me–it’s important–since what precise date they’ve been absent?”

The house-surgeon reflected for a moment–then he suddenly drew out a small memorandum book from an inner pocket.

“Perhaps I can,” he answered, turning the pages over. “Yes–both these men should have been in attendance on me–a class of my own, you know–on the 20th, at 10.35. They didn’t turn up. I’ve never seen them since–in fact, I’m sure they’ve never been at the hospital since.”

“The 20th?” observed Ayscough. He looked at Melky, who was paying great attention to the conversation. “Now let’s see–old Mr. Multenius met his death on the afternoon of the 18th. Parslett was poisoned on the night of the 19th, Um!”

“And Parslett was picked up about half-way between the Chink’s house and his own place, Mr. Ayscough–don’t you forget that!” muttered Melky. “I’m not forgetting–don’t you make no error!”

“You don’t know anything more that you could tell us about these two?” asked the detective, nodding reassuringly at Melky and then turning to the house-surgeon. “Any little thing?–you never know what helps.”

“I can’t!” said the house-surgeon, who was obviously greatly surprised by what he had seen and heard. “These Easterns keep very much to themselves, you know. I can’t think of anything.”

“Don’t know anything of their associates–friends–acquaintances?” suggested Ayscough. “I suppose they had some–amongst your students?”

“I never saw them in company with anybody–particularly–except a young Japanese who was in some of their classes,” replied the house-surgeon. “I have seen them talking with him–in Gower Street.”

“What’s his name?” asked Ayscough, pulling out a note-book.

“Mr. Mori Yada,” answered the house-surgeon promptly. “He lives in Gower Street–I don’t know the precise number of the house. Yes, that’s the way to spell his name. He’s the only man I know who seemed to know these two.”

“Have you seen him lately?” asked Ayscough.

“Oh, yes–regularly–today, in fact,” said the house-surgeon.

He waited a moment in evident expectation of other questions; as the detective asked none–“I gather,” he remarked, “that Chang Li has disappeared?”

“The house these two occupied is empty,” replied Ayscough.

“I am going to suggest something,” said the house-surgeon. “I know–from personal observation–that there is a tea-shop in Tottenham Court Road–a sort of quiet, privately-owned place–Pilmansey’s–which these two used to frequent. I don’t know if that’s of any use to you?”

“Any detail is of use, Sir,” answered Ayscough, making another note. “Now, I’ll tell this taxi-man to drive you back to the hospital. I shall call there tomorrow morning, and I shall want to see this young Japanese gentleman, too. I daresay you see that this is a case of murder–and there’s more behind it!”

“You suspect Chang Li?” suggested the house-surgeon as they went out to the cab.

“Couldn’t say that–yet,” replied Ayscough, grimly. “For anything I know, Chang Li may have been murdered, too. But I’ve a pretty good notion what Chen Li was knifed for!”

When the house-surgeon had gone away, Ayscough turned to Melky.

“Come back to Molteno Lodge,” he said. “They’re searching it. Let’s see if they’ve found anything of importance.”

The house which had been as lifeless and deserted when Melky and the detective visited it earlier in the evening was full enough of energy and animation when they went back. One policeman kept guard at the front gate; another at the door of the yard; within the house itself, behind closed doors and drawn shutters and curtains, every room was lighted and the lynx-eyed men were turning the place upside down. One feature of the search struck the newcomers immediately–the patch of ground whereon Melky had found the dead man had been carefully roped off. Ayscough made a significant motion of his hand towards it.

“Good!” he said, “that shows they’ve found footprints. That may be useful. Let’s hear what else they’ve found.”

The man in charge of these operations was standing within the dining-room when Ayscough and Melky walked in, and he at once beckoned them into the room and closed the door.

“We’ve made two or three discoveries,” he said, glancing at Ayscough. “To start with, there were footprints of a rather unusual sort round these bushes where the man was lying–so I’ve had it carefully fenced in around there–we’ll have a better look at ’em, in daylight. Very small prints, you understand–more like a woman’s than a man’s.”

Ayscough’s sharp eyes turned to the hearth–there were two or three pairs of slippers lying near the fender and he pointed to them.

“These Chinamen have very small feet, I believe,” he said. “The footprints are probably theirs. Well–what else?”

“This,” answered the man in charge, producing a small parcel from the side-pocket of his coat, and proceeding to divest it of a temporary wrapping. “Perhaps Mr. Rubinstein will recognize it. We found it thrown away in a fire-grate in one of the bedrooms upstairs–you see, it’s half burnt.”

He produced a small, stoutly-made cardboard box, some three inches square, the outer surface of which was covered with a thick, glossy-surfaced dark- green paper, on which certain words were deeply impressed in gilt letters. The box was considerably charred and only fragments of the lettering on the lid remained intact–but it was not difficult to make out what the full wording had been.

. . . . _enius_,
. . ._nd jeweller_,
. . _ed Street_.

“That’s one of the late Mr. Multenius’s boxes,” affirmed Melky at once. “Daniel Multenius, Pawnbroker and Jeweller, Praed Street–that’s the full wording. Found in a fireplace, d’ye say, mister? Ah–and what had he taken out of it before he threw the box away, now, Mr. Ayscough–whoever it was that did throw it away?”

“That blessed orange and yellow diamond, I should think!” said Ayscough. “Of course! Well, anything else?”

The man in charge carefully wrapped up and put away the jeweller’s box; then, with a significant glance at his fellow-detective, he slipped a couple of fingers into his waistcoat pocket and drew out what looked like a bit of crumpled paper.

“Aye!” he answered. “This! Found it–just there! Lying on the floor, at the end of this table.”

He opened out the bit of crumpled paper as he spoke and held it towards the other two. Ayscough stared, almost incredulously, and Melky let out a sharp exclamation.

“S’elp us!” he said. “A five-hundred-pound bank-note!”

“That’s about it,” remarked the exhibitor. “Bank of England note for five hundred of the best! And–a good ‘un, too. Lying on the floor.”

“Take care of it,” said Ayscough laconically. “Well–you haven’t found any papers, documents, or anything of that sort, that give any clue?”

“There’s a lot of stuff there,” answered the man in charge, pointing to a pile of books and papers on the table, “but it seems to be chiefly exercises and that sort of thing. I’ll look through it myself, later.”

“See if you can find any letters, addresses, and so on,” counselled Ayscough. He turned over some of the books, all of them medical works and text-books, opening some of them at random. And suddenly he caught sight of the name which the house-surgeon had given him half-an-hour before, written on a fly-leaf: Mori Yada, 491, Gower Street–and an idea came into his mind. He bade the man in charge keep his eyes open and leave nothing unexamined, and tapping Melky’s arm, led him outside. “Look here!” he said, drawing out his watch, as they crossed the hall, “it’s scarcely ten o’clock, and I’ve got the address of that young Jap. Come on–we’ll go and ask him a question or two.”

So for the second time that evening, Melky, who was beginning to feel as if he were on a chase which pursued anything but a straight course, found himself in Gower Street again, and followed Ayscough along, wondering what was going to happen next, until the detective paused at the door of a tall house in the middle of the long thoroughfare and rang the bell. A smart maid answered that ring and looked dubiously at Ayscough as he proffered a request to see Mr. Mori Yada. Yes–Mr. Yada was at home, but he didn’t like to see any one, of an evening when he was at his studies, and–in fact he’d given orders not to be disturbed at that time.

“I think he’ll see me, all the same,” said Ayscough, drawing out one of his professional cards. “Just give him that, will you, and tell him my business is very important.”

He turned to Melky when the girl, still looking unwilling, had gone away upstairs, and gave him a nudge of the elbow.

“When we get up there–as we shall,” whispered Ayscough, “you watch this Jap chap while I talk to him. Study his face–and see if anything surprises him.”

“Biggest order, mister–with a Jap!” muttered Melky. “Might as well tell me to watch a stone image–their faces is like wood!”

“Try it!” said Ayscough. “Flicker of an eyelid–twist of the lip– anything! Here’s the girl back again.”

A moment later Melky, treading close on the detective’s heels, found himself ushered into a brilliantly-lighted, rather over-heated room, somewhat luxuriously furnished, wherein, in the easiest of chairs, a cigar in his lips, a yellow-backed novel in his hand, sat a slimly-built, elegant young gentleman whose face was melting to a smile.

CHAPTER TWENTY-NINE

MR. MORI YADA

Ayscough was on his guard as soon as he saw that smile. He had had some experience of various national characteristics in his time, and he knew that when an Eastern meets you with a frank and smiling countenance you had better keep all your wits about you. He began the exercise of his own with a polite bow–while executing it, he took a rapid inventory of Mr. Mori Yada. About–as near as he could judge–two or three and twenty; a black-haired, black-eyed young gentleman; evidently fastidious about his English clothes, his English linen, his English ties, smart socks, and shoes–a good deal of a dandy, in short–and, judging from his surroundings, very fond of English comfort–and not averse to the English custom of taking a little spirituous refreshment with his tobacco. A decanter stood on the table at his elbow; a syphon of mineral water reared itself close by; a tumbler was within reach of Mr. Yada’s slender yellowish fingers.

“Servant, Sir!” said Ayscough. “Detective Sergeant Ayscough of the Criminal Investigation Department–friend of mine, this, Sir, Mr. Yada, I believe–Mr. Mori Yada?”

Mr. Yada smiled again, and without rising, indicated two chairs.

“Oh, yes!” he said in excellent English accents. “Pleased to see you–will you take a chair–and your friend! You want to talk to me?”

Ayscough sat down and unbuttoned his overcoat.

“Much obliged, Sir,” he said. “Yes–the fact is, Mr. Yada, I called to see you on a highly important matter that’s arisen. Your name, sir, was given to me tonight by one of the junior house-surgeons at the hospital up the street–Dr. Pittery.”

“Oh, yes, Dr. Pittery–I know,” agreed Yada. “Yes?”

“Dr. Pittery tells me, sir,” continued Ayscough, “that you know two Chinese gentlemen who are fellow-students of yours at the hospital, Mr. Yada?”

The Japanese bowed his dark head and blew out a mouthful of smoke from his cigar.

“Yes!” he answered readily, “Mr. Chang Li–Mr. Chen Li. Oh, yes!”

“I want to ask you a question, Mr. Yada,” said Ayscough, bending forward and assuming an air of confidence. “When did you see those two gentlemen last–either of them?”

Yada leaned back in his comfortably padded chair and cast his quick eyes towards the ceiling. Suddenly he jumped to his feet.

“You take a little drop of whisky-and-soda?” he said hospitably, pushing a clean glass towards Ayscough. “Yes–I will get another glass for your friend, too. Help yourselves, please, then–I will look in my diary for an answer to your question. You excuse me, one moment.”

He walked across the room to a writing cabinet which stood in one corner, and took up a small book that lay on the blotting-pad; while he turned over its pages, Ayscough, helping himself and Melky to a drink, winked at his companion with a meaning expression.

“I have not seen either Mr. Chang Li or Mr. Chen Li since the morning of the 18th November,” suddenly said Yada. He threw the book back on the desk, and coming to the hearthrug, took up a position with his back to the fire and his hands in the pockets of his trousers. He nodded politely as his visitors raised their glasses to him. “Is anything the matter, Mr. Detective-Sergeant?” he asked.

Ayscough contrived to press his foot against Melky’s as he gave a direct answer to this question.

“The fact of the case is, Mr. Yada,” he said, “one of these two young men has been murdered! murdered, sir!”

Yada’s well-defined eyebrows elevated themselves–but the rest of his face was immobile. He looked fixedly at Ayscough for a second or two–then he let out one word.

“Which?”

“According to Dr. Pittery–Chen Li,” answered Ayscough. “Dr. Pittery identified him. Murdered, Mr. Yada, murdered! Knifed!–in the throat.”

The reiteration of the word murdered appeared to yield the detective some sort of satisfaction–but it apparently made no particular impression on the Japanese. Again he rapped out one word.

“Where?”

“His body was found in the garden of the house they rented in Maida Vale,” replied Ayscough. “Molteno Lodge. No doubt you’ve visited them there, Mr. Yada?”

“I have been there–yes, a few times,” assented Yada. “Not very lately. But–where is Chang Li?”

“That’s what we don’t know–and what we want to know,” said Ayscough. “He’s not been seen at the hospital since the 20th. He didn’t turn up there–nor Chen, either, at a class, that day. And you say you haven’t seen them either since the 18th?”

“I was not at the hospital on the 19th,” replied Yada. He threw away the end of his cigar, picked up a fresh one from a box which stood on the table, pushed the box towards his visitors, and drew out a silver match- box. “What are the facts of this murder, Mr. Detective-Sergeant?” he asked quietly. “Murder is not done without some object–as a rule.”

Ayscough accepted the offered cigar, passed the box to Melky and while he lighted his selection, thought quietly. He was playing a game with the Japanese, and it was necessary to think accurately and quickly. And suddenly he made up his mind and assumed an air of candour.

“It’s like this, Mr. Yada,” he said. “I may as well tell you all about it. You’ve doubtless read all about this Praed Street mystery in the newspapers? Well, now, some very extraordinary developments have arisen out of the beginnings of that. It turns out.”

Melky sat by, disturbed and uncomfortable, while Ayscough reeled off a complete narrative of the recent discoveries to the suave-mannered, phlegmatic, calmly-listening figure on the hearthrug. He did not understand the detective’s doings–it seemed to him the height of folly to tell a stranger, and an Eastern stranger at that, all about the fact that there was a diamond worth eighty thousand pounds at the bottom of these mysteries and murders. But he discharged his own duties, and watched Yada intently–and failed to see one single sign of anything beyond ordinary interest in his impassive face.

“So there it is, sir,” concluded Ayscough. “I’ve no doubt whatever that Chen Li called at Multenius’s shop to pay the rent; that he saw the diamond in the old man’s possession and swagged him for it; that Parslett saw Chen Li slip away from that side-door and, hearing of Multenius’s death, suspected Chen Li of it and tried to blackmail him; that Chen Li poisoned Parslett–and that Chen Li himself was knifed for that diamond. Now–by whom? Chang Li has–disappeared!”

“You suspect Chang Li?” asked Yada.

“I do,” exclaimed Ayscough. “A Chinaman–a diamond worth every penny of eighty thousand pounds–Ah!” He suddenly lifted his eyes to Yada with a quick enquiry. “How much do you know of these two?” he asked.

“Little–beyond the fact that they were fellow-students of mine,” answered Yada. “I occasionally visited them–occasionally they visited me–that is all.”

“Dr. Pittery says they weren’t brothers?” suggested Ayscough.

“So I understood,” assented Yada. “Friends.”

“You can’t tell us anything of their habits?–haunts?–what they usually did with themselves when they weren’t at the hospital?” asked the detective.

“I should say that when they weren’t at the hospital, they were at their house–reading,” answered Yada, drily. “They were hard workers.”

Ayscough rose from his chair.

“Well, much obliged to you, Sir,” he said. “As your name was mentioned as some sort of a friend of theirs, I came to you. Of course, most of what I’ve told you will be in all the papers tomorrow. If you should hear anything of this Chang Li, you’ll communicate with us, Mr. Yada?”

The Japanese smiled–openly.

“Most improbable, Mr. Detective-Sergeant!” he answered. “I know no more than what I have said. For more information, you should go to the Chinese Legation.”

“Good idea, sir–thank you,” said Ayscough.

He bowed himself and Melky out; once outside the street-door he drew his companion away towards a part which lay in deep shadow. Some repairing operations to the exterior of a block of houses were going on there; underneath a scaffolding which extended over the sidewalk Ayscough drew Melky to a halt.

“You no doubt wondered why I told that chap so much?” he whispered. “Especially about that diamond! But I had my reasons–and particularly for telling him about its value.”

“It isn’t what I should ha’ done, Mr. Ayscough,” said Melky, “and it didn’t ought to come out in the newspapers, neither–so I think! ‘Tain’t a healthy thing to let the public know there’s an eighty-thousand pound diamond loose somewhere in London–and as to telling that slant-eyed fellow in there–“

“You wait a bit, my lad!” interrupted Ayscough. “I had my reasons–good ‘uns. Now, look here, we’re going to watch that door awhile. If the Jap comes out–as I’ve an idea he will–we’re going to follow. And as you’re younger, and slimmer, and less conspicuous than I am, if he should emerge, keep on the shadowy side of the street, at a safe distance, and follow him as cleverly as you can. I’ll follow you.”

“What new game’s this?” asked Melky.

“Never mind!” replied Ayscough. “And, if it does come to following, and he should take a cab, contrive to be near–there’s a good many people about, and if you’re careful he’ll never see you. And–there, now, what did I tell you? He’s coming out, now! Be handy–more depends on it than you’re aware of.”

Yada, seen clearly in the moonlight which flooded that side of the street, came out of the door which they had left a few minutes earlier. His smart suit of grey tweed had disappeared under a heavy fur-collared overcoat; a black bowler hat surmounted his somewhat pallid face. He looked neither to right nor left, but walked swiftly up the street in the direction of the Euston Road. And when he had gone some thirty yards, Ayscough pushed Melky before him out of their retreat.

“You go first,” he whispered, “I’ll come after you. Keep an eye on him as far as you can–didn’t I tell you he’d come out when we’d left? Be wary!”

Melky slipped away up the street on the dark side and continued to track the slim figure quickly advancing in the moonlight. He followed until they had passed the front of the hospital–a few yards further, and Yada suddenly crossed the road in the direction of the Underground Railway. He darted in at the entrance to the City-bound train, and disappeared, and Melky, uncertain what to do, almost danced with excitement until Ayscough came leisurely towards him. “Quick! quick!” exclaimed Melky. “He’s gone down there–City trains. He’ll be off unless you’re on to him!”

But Ayscough remained quiescent and calmly relighted his cigar.

“All right, my lad,” he said. “Let him go–just now. I’ve seen–what I expected to see!”

CHAPTER THIRTY

THE MORTUARY

Melky, who had grown breathless in his efforts to carry out his companion’s wishes, turned and looked at him with no attempt to conceal his wonder.

“Well, s’elp me if you ain’t a cool ‘un, Mr. Ayscough!” he exclaimed. “Here you troubles to track a chap to this here Underground Railway, seen him pop into it like a rabbit into a hole–and let’s him go! What did we follow him up Gower Street for? Just to see him set off for a ride?”

“All right, my lad!” repeated Ayscough. “You don’t quite understand our little ways. Wait here a minute.”

He drew one of his cards from his pocket and carrying it into the booking office exchanged a few words with the clerk at the window. Presently he rejoined Melky. “He took a ticket for Whitechapel,” remarked Ayscough as he strolled quietly up. “Ah! now what does a young Japanese medical student want going down that way at eleven o’clock at night? Something special, no doubt, Mr. Rubinstein. However, I’m going westward just now. Just going to have a look in at the Great Western Hotel, to see if Mr. Purdie heard anything from that American chap–and then I’m for home and bed. Like to come to the hotel with me?”

“Strikes me we might as well make a night of it!” remarked Melky as they recrossed the road and sought a west-bound train. “We’ve had such an evening as I never expected! Mr. Ayscough! when on earth is this going to come to something like a clearing-up?”

Ayscough settled himself in a corner of a smoking-carriage and leaned back.

“My own opinion,” he said, “is that it’s coming to an end. Tomorrow, the news of the Chinaman’s murder’ll be the talk of the town. And if that doesn’t fetch Levendale out of whatever cranny he’s crept into, hanged if I know what will!”

“Ah! you think that, do you?” said Melky. “But–why should that news fetch him out?”

“Don’t know!” replied Ayscough, almost unconcernedly. “But I’m almost certain that it will. You see–I think Levendale’s looking for Chen Li. Now, if Levendale hears that Chen Li’s lying dead in our mortuary–what? See?”

Melky murmured that Mr. Ayscough was a cute ‘un, and relapsed into thought until the train pulled up at Praed Street. He followed the detective up the streets and across the road to the hotel, dumbly wondering how many times that day he had been in and about that quarter on this apparently interminable chase. He was getting dazed–but Ayscough who was still smoking the cigar which Yada had given him, strode along into the hotel entrance apparently as fresh as paint.

Purdie had a private sitting-room in connection with his bedroom, and there they found him and Lauriston, both smoking pipes and each evidently full of thought and speculation. They jumped to their feet as the detective entered.

“I say!” exclaimed Lauriston. “Is this true?–this about the Chinese chap? Is it what they think at your police-station?–connected with the other affairs? We’ve been waiting, hoping you’d come in!”

“Ah!” said Ayscough, dropping into a chair. “We’ve been pretty busy, me and Mr. Rubinstein there–we’ve had what you might call a pretty full evening’s work of it. Yes–it’s true enough, gentlemen–another step in the ladder–another brick in the building! We’re getting on, Mr. Purdie, we’re getting on! So you’ve been round to our place?–they told you, there!”

“They gave us a mere outline,” answered Purdie. “Just the bare facts. I suppose you’ve heard nothing of the other Chinaman?”

“Not a circumstance–as yet,” said Ayscough. “But I’m in hopes–I’ve done a bit, I think, towards it–with Mr. Rubinstein’s help, though he doesn’t quite understand my methods. But you, gentlemen–I came in to hear if you’d anything to tell about Guyler. What did he think about what John Purvis had to tell us this afternoon?”

“He wasn’t surprised,” answered Purdie. “Don’t you remember that he assured us from the very start that diamonds would be found to be at the bottom of this. But he surprised us!”

“Aye? How?” asked Ayscough. “Some news?”

“Guyler swears that he saw Stephen Purvis this very morning,” replied Purdie. “He’s confident of it!”

“Saw Stephen Purvis–this very morning!” exclaimed Ayscough. “Where, now?’

“Guyler had business down in the City–in the far end of it,” said Purdie. “He was crossing Bishopsgate when he saw Stephen Purvis–he swears it was Stephen Purvis!–nothing can shake him! He, Purvis, was just turning the corner into a narrow alley running out of the street. Guyler rushed after him–he’d disappeared. Guyler waited, watching that alley, he says, like a cat watches a mouse-hole–and all in vain. He watched for an hour–it was no good.”

“Pooh!” said Ayscough. “If it was Purvis, he’d walked straight through the alley and gone out at the other end.”

“No!” remarked Lauriston. “At least, not according to Guyler. Guyler says it was a long, narrow alley–Purvis could have reached one end by the time he’d reached the other. He says–Guyler–that on each side of that alley there are suites of offices–he reckoned there were a few hundred separate offices in the lot, and that it would take him a week to make enquiry at the doors of each. But he’s certain that Purvis disappeared into one block of them and dead certain that it was Stephen Purvis that he saw. So– Purvis is alive!”

“Where’s the other Purvis–the farmer?” asked Ayscough.

“Stopping with Guyler at the Great Northern,” answered Lauriston. “We’ve all four been down in the City, looking round, this evening. Guyler and John Purvis are going down again first thing in the morning. John Purvis, of course, is immensely relieved to know that Guyler’s certain about his brother. I say!–do you know what Guyler’s theory is about that diamond of Stephen’s?”

“No–and what might Mr. Guyler’s theory be, now Mr. Lauriston?” enquired the detective. “There’s such a lot of ingenious theories about that one may as well try to take in another. Mr. Rubinstein there is about weary of theories.”

But Melky was pricking his ears at the mere mention of anything relating to the diamond.

“That’s his chaff, Mr. Lauriston,” he said. “Never mind him! What does Guyler think?”

“Well, of course, Guyler doesn’t know yet about the Chinese development,” said Lauriston. “Guyler thinks the robbery has been the work of a gang–a clever lot of diamond thieves who knew about Stephen Purvis’s find of the orange-yellow thing and put in a lot of big work about getting it when it reached England. And he believes that that gang has kidnapped Levendale, and that Stephen Purvis is working in secret to get at them. That’s Guyler’s notion, anyhow.”

“Well!” said Ayscough. “And there may be something in it! For this search –how do we know that at any rate one of these Chinamen mayn’t have had some connection with this gang? You never know–and to get a dead straight line at a thing’s almost impossible. However, we’ve taken steps to have the news about the diamond and about this Chen Li appear in tomorrow morning’s papers, and if that doesn’t rouse the whole town–“

A tap at the door prefaced the entrance of a waiter, who looked apologetically at its inmates.

“Beg pardon, gentlemen,” he said, “Mr. Ayscough? Gentleman outside would like a word with you, if you please, sir.”

Ayscough picked up his hat and walked out–there, waiting a little way down the corridor, an impressive figure in his big black cloak and wide- brimmed hat, stood Dr. Mirandolet. He strode forward as the detective advanced.

“I heard you were here, so I came up,” he said, leading Ayscough away. “Look here, my friend–one of your people has told me of this affair at Molteno Lodge–the discovery of the Chinaman’s dead body.”

“That young fellow, Rubinstein, who called on you early this evening, and got me to accompany him discovered it,” said Ayscough, who was wondering what the doctor was after. “I was with him.”

“I have heard, too,” continued Mirandolet, “also from one of your people, about the strange story of the diamond which came out this afternoon, from the owner’s brother. Now–I’ll tell you why after–I want to see that dead Chinaman! I’ve a particular reason. Will you come with me to the mortuary?”

Ayscough’s curiosity was aroused by Mirandolet’s manner, and without going back to Purdie’s room, he set out with him. Mirandolet remained strangely silent until they came to the street in which the mortuary stood.

“A strange and mysterious matter this, my friend!” he said. “That little Rubinstein man might have had some curious premonition when he came to me tonight with his odd question about Chinese!”

“Just what I said myself, doctor!” agreed Ayscough.

“It did look as if he’d a sort of foreboding, eh? But–Hullo!”

He stopped short as a taxi-cab driven at a considerable speed, came rushing down the street and passing them swiftly turned into the wider road beyond. And the sudden exclamation was forced from his lips because it seemed to him that as the cab sped by he saw a yellow-hued face within it–for the fraction of a second. Quick as that glimpse was, Ayscough was still quicker as he glanced at the number on the back of the car–and memorized it.

“Odd!” he muttered, “odd! Now, I could have sworn–” He broke off, and hurried after Mirandolet who had stridden ahead. “Here we are, doctor,” he said, as they came to the door of the mortuary. “There’s a man on night duty here, so there’s no difficulty about getting in.”

There was a drawing of bolts, a turning of keys; the door opened, and a man looked out and seeing Ayscough and Dr. Mirandolet, admitted them into an ante-room and turned up the gas.

“We want to see that Chinaman, George,” said the detective. “Shan’t keep you long.”

“There’s a young foreign doctor just been to see him, Mr. Ayscough,” said the man. “You’d pass his car down the street–he hasn’t been gone three minutes. Young Japanese–brought your card with him.”

Ayscough turned on the man as if he had given him the most startling news in the world.

“What?” he exclaimed, “Japanese? Brought my card?”

“Showed me it as soon as he got here,” answered the attendant, surprised at Ayscough’s amazement. “Said you’d given it to him, so that he could call here and identify the body. So, of course, I let him go in.”

Ayscough opened his mouth in sheer amazement. But before he could get out a word, Mirandolet spoke, seizing the mortuary-keeper by the arm in his eagerness.

“You let that man–a Japanese–see the dead Chinaman–_alone_?” he demanded.

“Why, of course!” the attendant answered surlily. “He’d Mr. Ayscough’s card, and–“

Mirandolet dropped the man’s arm and threw up his own long white hands.

“Merciful Powers!” he vociferated. “He has stolen the diamond!”

CHAPTER THIRTY-ONE

THE MIRANDOLET THEORY

The silence that followed on this extraordinary exclamation was suddenly broken: the mortuary keeper, who had been advancing towards a door at the side of the room, dropped a bunch of keys. The strange metallic sound of their falling roused Ayscough, who had started aside, and was staring, open-mouthed, at Mirandolet’s waving hands. He caught the doctor by the arm.

“What on earth do you mean?” he growled. “Speak man–what is it?”

Mirandolet suddenly laughed.

“What is it?” he exclaimed. “Precisely what I said, in plain language! That fellow has, of course, gone off with the diamond–worth eighty thousand pounds! Your card!–Oh, man, man, whatever have you been doing? Be quick!–who is this Japanese?–how came he by your card? Quick, I say! –if you want to be after him!”

“Hanged if I know what this means!” muttered Ayscough. “As to who he is– if he’s the fellow I gave a card to, he’s a young Japanese medical student, one Yada, that was a friend of those Chinese–I called on him tonight, with Rubinstein, to see if we could pick up a bit of information. Of course, I sent in my professional card to him. But–we saw him set off to the East End!”

“Bah!” laughed Mirandolet. “He has–what you call done you brown, my friend! He came–here! And he has got away–got a good start–with that diamond in his pocket!”

“What the devil do you mean by that?” said Ayscough, hotly. “Diamond! Diamond! Where should he find the diamond–here? In a deadhouse? What are you talking about?”

Mirandolet laughed again, and giving the detective a look that was very like one of pitying contempt, turned to the amazed mortuary keeper.

“Show us that dead man!” he said.

The mortuary keeper, who had allowed his keys to lie on the floor during this strange scene, picked them up, and selecting one, opened, and threw back the door by which he was standing. He turned on the light in the mortuary chamber, and Mirandolet strode in, with Ayscough, sullen and wondering, at his heels.

Chen Li lay where the detective had last seen him, still and rigid, the sheet drawn carefully over his yellow face. Without a word Mirandolet drew that sheet aside, and motioning his companion to draw nearer, pointed to a skull-cap of thin blue silk which fitted over the Chinaman’s head.

“You see that!” he whispered. “You know what’s beneath it!–something that no true Chinaman ever parts with, even if he does come to Europe, and does wear English dress and English headgear–his pigtail! Look here!”

He quietly moved the skull-cap, and showed the two astonished men a carefully-coiled mass of black hair, wound round and round the back of the head. And into it he slipped his own long, thin fingers–to draw them out again with an exclamation which indicated satisfaction with his own convictions.

“Just as I said,” he remarked. “Gone! Mr. Detective–that’s where Chen Li hid the diamond–and that Japanese man has got it. And now–you’d better be after him–half-an-hour’s start to him is as good as a week’s would be to you.”

He drew the sheet over the dead face and strode out, and Ayscough followed, angry, mystified, and by no means convinced.

“Look here!” he said, as they reached the ante-room; “that’s all very well, Dr. Mirandolet, but it’s only supposition on your part!”

“Supposition that you’ll find to be absolute truth, my good friend!” retorted Mirandolet, calmly. “I know the Chinese–better than you think. As soon as I heard of this affair tonight, I came to you to put you up to the Chinese trick of secreting things of value in their pigtails–it did not occur to me that the diamond might be there in this case, but I thought you would probably find something. But when we reached this mortuary, and I heard that a Japanese had been here, presenting your card when he had no business to present it, I guessed immediately what had happened–and now that you tell me that you told him all about this affair, well–I am certain of my assertion. Mr. Detective–go after the diamond!”

He turned as if to leave the place, and Ayscough followed.

“He mayn’t been after the diamond at all!” he said, still resentful and incredulous. “Is it very likely he’d think it to be in that dead chap’s pigtail when the other man’s missing? It’s Chang that’s got that diamond– not Chen.”

“All right, my friend!” replied Mirandolet. “Your wisdom is superior to mine, no doubt. So–I wish you good-night!”

He strode out of the place and turned sharply up the street, and Ayscough, after a growl or two, went back to the mortuary keeper.

“How long was that Jap in there?” he asked, nodding at the death chamber.

“Not a minute, Mr. Ayscough!” replied the man. “In and out again, as you might say.”

“Did he say anything when he came out?” enquired the detective.

“He did–two words,” answered the keeper. “He said, ‘That’s he!’ and walked straight out, and into his car.”

“And when he came he told you I’d sent him?” demanded Ayscough.

“Just that–and showed me your card,” assented the man. “Of course, I’d no reason to doubt his word.”

“Look here, George!” said Ayscough, “you keep this to yourself! Don’t say anything to any of our folks if they come in. I don’t half believe what that doctor said just now–but I’ll make an enquiry or two. Mum’s the word, meanwhile. You understand, George?”

George answered that he understood very well, and Ayscough presently left him. Outside, in the light of the lamp set over the entrance to the mortuary, he pulled out his watch. Twelve o’clock–midnight. And somewhere, that cursed young Jap was fleeing away through the London streets–having cheated him, Ayscough, at his own game!

He had already reckoned things up in connection with Yada. Yada had been having him–even as Melky Rubinstein had suspected and suggested–all through that conversation at Gower Street. Probably, Yada, from his window in the drawing-room floor of his lodging-house, had watched him and Melky slip across the street and hide behind the hoarding opposite. And then Yada had gone out, knowing he was to be followed, and had tricked them beautifully, getting into an underground train going east, and, in all certainty, getting out again at the next station, chartering a cab, and returning west–with Ayscough’s card in his pocket.

But Ayscough knew one useful thing–he had memorized the letters and numbers of the taxi-cab in which Yada had sped by him and Mirandolet, L.C. 2571–he had kept repeating that over and over. Now he took out his note- book and jotted it down–and that done he set off to the police-station, intent first of all on getting in touch with New Scotland Yard by means of the telephone.

Ayscough, like most men of his calling in London, had a considerable amount of general knowledge of things and affairs, and he summoned it to his aid in this instance. He knew that if the Japanese really had become possessed of the orange and yellow diamond (of which supposition, in spite of Mirandolet’s positive convictions, he was very sceptical) he would most certainly make for escape. He would be off to the Continent, hot foot. Now, Ayscough had a good acquaintance with the Continental train services –some hours must elapse before Yada could possibly get a train for Dover, or Folkstone, or Newhaven, or the shortest way across, or to any other ports such as Harwich or Southampton, by a longer route. Obviously, the first thing to do was to have the stations at Victoria, and Charing Cross, and Holborn Viaduct, and London Bridge carefully watched for Yada. And for two weary hours in the middle of the night he was continuously at work on the telephone, giving instructions and descriptions, and making arrangements to spread a net out of which the supposed fugitive could not escape.

And when all that was at last satisfactorily arranged, Ayscough was conscious that it might be for nothing. He might be on a wrong track altogether–due to the suspicions and assertions of that queer man, Mirandolet. There might be some mystery–in Ayscough’s opinion there always was mystery wherever Chinese or Japanese or Hindus were concerned. Yada might have some good reason for wishing to see Chen Li’s dead body, and have taken advantage of the detective’s card to visit it. This extraordinary conduct might be explained. But meanwhile Ayscough could not afford to neglect a chance, and tired as he was, he set out to find the driver of the taxicab whose number he had carefully set down in his notebook.

There was little difficulty in this stage of the proceedings; it was merely a question of time, of visiting a central office and finding the man’s name and address. By six o’clock in the morning Ayscough was at a small house in a shabby street in Kentish Town, interviewing a woman who had just risen to light her fire, and was surlily averse to calling up a husband, who, she said, had not been in bed until nearly four. She was not any more pleased when Ayscough informed her of his professional status– but the man was fetched down.

“You drove a foreigner–a Japanese–to the mortuary in Paddington last night?” said Ayscough, plunging straight into business, after telling the man who he was. “I saw him–just a glimpse of him–in your cab, and I took your number. Now, where did you first pick him up?”

“Outside the Underground, at King’s Cross,” replied the driver promptly.

This was precisely what Ayscough had expected; so far, so good; his own prescience was proving sure.

“Anything wrong, mister?” asked the driver.

“There may be,” said Ayscough. “Well–you picked him up there, and drove him straight to the mortuary?”

“No–I didn’t,” said the man. “We made a call first. Euston. He went in there, and, I should say, went to the left luggage office, ’cause he came back again with a small suit-case–just a little’un. Then we went on to that mortuary.”

Euston! A small suit-case! More facts–Ayscough made notes of them.

“Well,” he said, “and when you drove away from the mortuary, where did you go then?”

“Oxford Circus,” answered the driver, “set him down–his orders–right opposite the Tube Station–t’other side of the street.”

“Did you see which way he went–then?” enquired Ayscough.

“I did. Straight along Oxford Street–Tottenham Court Road way,” said the driver, “carrying his suitcase–which it was, as I say, on’y a little ‘un –and walking very fast. Last I see of him was that, guv’nor.”

Ayscough went away and got back to more pretentious regions. He was dead tired and weary with his night’s work, and glad to drop in at an early- opened coffee-shop and get some breakfast. While he ate and drank a boy came in with the first editions of the newspapers. Ayscough picked one up –and immediately saw staring headlines:–

THE PADDINGTON MYSTERIES.
NEW AND STARTLING FEATURES.
DIAMOND WORTH L80,000 BEING LOOKED FOR MURDER IN MAIDA VALE

Ayscough laid down the paper and smiled. Levendale–if not dead–could scarcely fail to see that!

CHAPTER THIRTY-TWO

ONE O’CLOCK MIDNIGHT

Five minutes after Ayscough had gone away with Dr. Mirandolet the hotel servant who had summoned him from Purdie’s sitting-room knocked at the door for the second time and put a somewhat mystified face inside.

“Beg pardon, sir,” he said, glancing at Purdie, who was questioning Melky Rubinstein as to the events of the evening in their relation to the house in Maida Vale. “Two ladies outside, sir–waiting to see you. But they don’t want to come in, sir, unless they know who’s here–don’t want to meet no strangers, sir.”

Purdie jumped to his feet, and putting the man aside looked into the dimly-lighted corridor. There, a few paces away, stood Zillah–and, half hidden by her, Mrs. Goldmark.

“Come in–come in!” he exclaimed. “Nobody here but Andie Lauriston and Melky Rubinstein. You’ve something to tell–something’s happened?”

He ushered them into the room, sent the hotel servant, obviously in a state of high curiosity about these happenings, away, and closed the door.

“S’elp me!” exclaimed Melky, “there ain’t no other surprises, Zillah? You ain’t come round at this time o’ night for nothing! What you got to tell, Zillah?–another development?”

“Mrs. Goldmark has something to tell,” answered Zillah. “We didn’t know what to do, and you didn’t come, Melky–nobody come–and so we locked the house and thought of Mr. Purdie. Mrs. Goldmark has seen somebody!”

“Who?” demanded Melky. “Somebody, now? What somebody?”

“The man that came to her restaurant,” replied Zillah. “The man who lost the platinum solitaire!”

Mrs. Goldmark who had dropped into the chair which Purdie had drawn to the side of the table for her, wagged her head thoughtfully.

“This way it was, then,” she said, with a dramatic suggestion of personal enjoyment in revealing a new feature of the mystery, “I have a friend who lives in Stanhope Street–Mrs. Isenberg. She sends to me at half-past-ten to tell me she is sick. I go to see her–immediate. I find her very poorly–so! I stop with her till past eleven, doing what I can. Then her sister, she comes–I can do no more–I come away. And I walk through Sussex Square, as my road back to Praed Street and Zillah. But before I am much across Sussex Square, I stop–sudden, like that! For what? Because–I see a man! That man! Him what drops his cuff-link on my table. Oh, yes!”

“You’re sure it was that man, Mrs. Goldmark?” enquired Melky, anxiously. “You don’t make no mistakes, so?”

“Do I mistake myself if I say I see you, Mr. Rubinstein?” exclaimed Mrs. Goldmark, solemnly and with emphasis. “No, I don’t make no mistakes at all. Is there not gas lamps?–am I not blessed with good eyes? I see him– like as I see you there young gentleman and Zillah. Plain!”

“Well–and what was he doing?” asked Purdie, desirous of getting at facts. “Did he come out of a house, or go into one, or–what?”

“I tell you,” replied Mrs. Goldmark, “everything I tell you–all in good time. It is like this. A taxicab comes up–approaching me. It stops–by the pavement. Two men–they get out. Him first. Then another. They pay the driver–then they walk on a little–just a few steps. They go into a house. The other man–he lets them into that house. With a latch-key. The door opens–shuts. They are inside. Then I go to Zillah and tell her what I see. So!”

The three young men exchanged glances, and Purdie turned to the informant.

“Mrs. Goldmark,” he said, “did you know the man who opened the door?”

“Not from another!” replied Mrs. Goldmark. “A stranger to me!”

“Do you know Mr. Levendale–by sight?” asked Purdie.

“Often, since all this begins, I ask myself that question,” said Mrs. Goldmark, “him being, so to speak, a neighbour. No, that I do not, not being able to say he was ever pointed out to me.”

“Well, you can describe the man who pulled out his latch-key and opened the door, anyhow,” remarked Purdie. “You took a good look at him, I suppose!”

“And a good one,” answered Mrs. Goldmark. “He was one of our people–I saw his nose and his eyes. And I was astonished to see so poor-looking a man have a latch-key to so grand a mansion as that!–he was dressed in poor clothes, and looked dirty and mean.”

“A bearded dark man?” suggested Purdie.

“Not at all,” said Mrs. Goldmark. “A clean-shaved man–though dark he might be.”

Purdie looked at Melky and shook his head.

“That’s not Levendale!” he said, “Clean-shaven! Levendale’s bearded and mustached–and I should say a bit vain of his beard. Um! you’re dead certain, Mrs. Goldmark, about the other man?”

“As that I tell you this,” insisted Mrs. Goldmark. “I see him as plain as what I see him when he calls at my establishment and leaves his jewellery on my table. Oh, yes–I don’t make no mistake, Mr. Purdie.”

Purdie looked again at Melky–this time with an enquiry in his glance.

“Don’t ask me, Mr. Purdie!” said Melky. “I don’t know what to say. Sounds like as if these two went into Levendale’s house. But what man would have a latch-key to that but Levendale himself? More mystery!–ain’t I full of it already? Now if Mr. Ayscough hadn’t gone away–“

“Look here!” said Purdie, coming to a sudden decision, “I’m going round there. I want to know what this means–I’m going to know. You ladies had better go home. If you others like to come as far as the corner of Sussex Square, come. But I’m going to Levendale’s house alone. I’ll find something out.”

He said no more until, Zillah and Mrs. Goldmark having gone homeward, and he and his two companions having reached a side street leading into Sussex Square, he suddenly paused and demanded their attention!

“I’ve particular reasons for wanting to go into that house alone,” he said. “There’s no danger–trust me. But–if I’m not out again in a quarter of an hour or so, you can come there and ask for me. My own impression is that I shall find Levendale there. And–as you’re aware, Andie–I know Levendale.” He left them standing in the shadow of a projecting portico and going up to Levendale’s front door, rang the bell. There was no light in any of the windows; all appeared to be in dead stillness in the house; somewhere, far off in the interior, he heard the bell tinkle. And suddenly, as he stood waiting and listening, he heard a voice that sounded close by him and became aware that there was a small trap or grille in the door, behind which he made out a face.

“Who is that?” whispered the voice.

“John Purdie–wanting to see Mr. Levendale,” he answered promptly.

The door was just as promptly opened, and as Purdie stepped within was as quickly closed behind him. At the same instant the click of a switch heralded a flood of electric light, and he started to see a man standing at his side–a man who gave him a queer, deprecating smile, a man who was not and yet who was Levendale.

“Gracious me!” exclaimed Purdie, “it isn’t–“

“Yes!” said Levendale, quietly. “But it is, though! All right, Purdie– come this way.”

Purdie followed Levendale into a small room on the right of the hall–a room in which the remains of a cold, evidently impromptu supper lay on a table lighted by a shaded lamp. Two men had been partaking of that supper, but Levendale was alone. He gave his visitor another queer smile, and pointed, first to a chair and then to a decanter.

“Sit down–take a drink,” he said. “This is a queer meeting! We haven’t seen each other since–“

“Good God, man!” broke in Purdie, staring at his host. “What’s it all mean? Are you–disguised?”

Levendale laughed–ruefully–and glanced at the mean garments which Mrs. Goldmark had spoken of.

“Necessity!” he said. “Had to! Ah!–I’ve been through some queer times– and in queer places. Look here–what do you know?”

“Know!” cried Purdie. “You want me to tell you all I know–in a sentence? Man!–it would take a month! What do you know? That’s more like it!”

Levendale passed a hand across his forehead–there was a weariness in his gesture which showed his visitor that he was dead beat.

“Aye, just so!” he said. “But–tell me! has John Purvis come looking for his brother?”

“He has!” answered Purdie. “He’s in London just now.”

“Has he told about that diamond?–told the police?” demanded Levendale.

“He has!” repeated Purdie. “That’s all known. Stephen Purvis–where is he?”

“Upstairs–asleep–dead tired out,” said Levendale. “We both are! Night and day–day and night–I could fall on this floor and sleep–“

“You’ve been after that diamond?” suggested Purdie.

“That–and something else,” said Levendale.

“Something else?” asked Purdie. “What then?”

“Eighty thousand pounds,” answered Levendale. “Just that!”

Purdie stood staring at him. Then he suddenly put a question.

“Do you know who murdered that old man in Praed Street?” he demanded. “That’s what I’m after.”

“No!” said Levendale, promptly. “I don’t even know that he was murdered!” He, too, stared at his visitor for a moment; then “But I know more than a little about his being robbed,” he added significantly.

Purdie shook his head. He was puzzled and mystified beyond measure.

“This is getting too deep for me!” he said. “You’re the biggest mystery of all, Levendale. Look here!” he went on. “What are you going to do? This queer disappearance of yours–this being away–coming back without your beard and dressed like that!–aren’t you going to explain? The police–“

“Yes!” said Levendale. “Ten o’clock this morning–the police-station. Be there–all of you–anybody–anybody who likes–I’m going to tell the police all I know. Purvis and I, we can’t do any more–baffled, you understand! But now–go away, Purdie, and let me sleep–I’m dead done for!”

Within ten minutes of leaving them, Purdie was back with Lauriston and Melky Rubinstein, and motioning them away from Sussex Square.

“That’s more extraordinary than the rest!” he said, as they all moved off. “Levendale’s there, in his own house, right enough! And he’s shaved off his beard and mustache, and he’s wearing tramp’s clothes and he and Stephen Purvis have been looking night and day, for that confounded diamond, and for eighty thousand pounds! And–what’s more, Levendale does not know who killed Daniel Multenius or that he was murdered! But, by George, sirs!” he added, as high above their heads the clock of St. James’s Church struck one, “he knows something big!–and we’ve got to wait nine hours to hear it!”

CHAPTER THIRTY-THREE

SECRET WORK

The inner room of the police-station, at ten o’clock that morning, was full of men. Purdie, coming there with Lauriston at five minutes before the hour, found Melky Rubinstein hanging about the outer door, and had only just time to warn his companion to keep silence as to their midnight discovery before Guyler and John Purvis drove up in one cab and Mr. Killick in another. Inside, Ayscough, refreshed by his breakfast and an hour’s rest, was talking to the inspector and the man from New Scotland Yard–all these looked enquiringly at the group which presently crowded in on them.

“Any of you gentlemen got any fresh news?” demanded the inspector, as he ran his eye over the expectant faces “No?–well, I suppose you’re all wanting to know if we have?” He glanced at Ayscough, who was pointing out certain paragraphs in one of the morning newspapers to the Scotland Yard man. “The fact is,” he continued, “there have been queer developments since last night–and I don’t exactly know where we are! My own opinion is that we’d better wait a few hours before saying anything more definite–to my mind, these newspapers are getting hold of too much news–giving information to the enemy, as it were. I think you’d all better leave things to us, gentlemen–for a while.” There was rather more than a polite intimation in this that the presence of so many visitors was not wanted– but John Purvis at once assumed a determined attitude.

“I want to know exactly what’s being done, and what’s going to be done, about my brother!” he said. “I’m entitled to that! That’s the job I came about–myself–as for the rest–“

“Your brother’s here!” said Purdie, who was standing by the window and keeping an eye on the street outside. “And Mr. Levendale with him–hadn’t you better have them straight in?” he went on, turning to the inspector. “They both look as if they’d things to tell.”

But Ayscough had already made for the door and within a moment was ushering in the new arrivals. And Purdie was quick to note that the Levendale who entered, a sheaf of morning papers in his hand, was a vastly different Levendale to the man he had seen nine hours before, dirty, unkempt, and worn out with weariness. The trim beard and mustache were hopelessly lost, and there were lines on Levendale’s face which they concealed, but Levendale himself was now smartly groomed and carefully dressed, and business-like, and it was with the air of a man who means business that he strode into the room and threw a calm nod to the officials.

“Now, Inspector,” he said, going straight to the desk, while Stephen Purvis turned to his brother. “I see from the papers that you’ve all been much exercised about Mr. Purvis and myself–it just shows how a couple of men can disappear and give some trouble before they’re found. But here we are!–and why we’re here is because we’re beaten–we took our own course in trying to find our own property–and we’re done! We can do no more–and so we come to you.”

“You should have come here at first, Mr. Levendale,” said the Inspector, a little sourly. “You’d have saved a lot of trouble–to yourselves as well as to us. But that’s neither here nor there–I suppose you’ve something to tell us, Sir?”

“Before I tell you anything,” replied Levendale, “I want to know something.” He pointed to the morning papers which he had brought in. “These people,” he said, “seem to have got hold of a lot of information– all got from you, of course. Now, we know what we’re after–let’s put it in a nutshell. A diamond–an orange-yellow diamond–worth eighty thousand pounds, the property of Mr. Stephen Purvis there. That’s item one! But there’s another. Eighty thousand pounds in banknotes!–my property. Now– have any of you the least idea who’s got the diamond and my money? Come!”

There was a moment’s silence. Then Ayscough spoke.

“Not a definite idea, Mr. Levendale–as yet.”

“Then I’ll tell you,” said Levendale. “A Chinese fellow–one Chang Li. He’s got them–both! And Stephen Purvis and I have been after him for all the days and nights since we disappeared–and we’re beaten! Now you’ll have to take it up–and I’d better tell you the plain truth about what’s no doubt seemed a queer business from the first. Half-an-hour’s talk now will save hours of explanation later on. So listen to me, all of you–I already see two gentlemen here, Mr. Killick, and Mr. Guyler, who in a certain fashion, can corroborate some particulars that I shall give you. Keep us free from interruption, if you please, while I tell you my story.”

Ayscough answered this request by going to the door and leaning against it, and Levendale took a chair by the side of the desk and looked round at an expectant audience.

“It’s a queer and, in some respects, an involved story,” he said, “but I shall contrive to make matters plain to you before I’ve finished. I shall have to go back a good many years–to a time when, as Mr. Killick there knows, I was a partner with Daniel Molteno in a jewellery business in the City. I left him, and went out to South Africa, where I engaged in diamond trading. I did unusually well in my various enterprises, and some years later I came back to London a very well-to-do man. Not long after my return, I met my former partner again. He had changed his name to Multenius, and was trading in Praed Street as a jeweller and pawnbroker. Now, I had no objection to carrying on a trade with certain business connections of mine at the Cape–and after some conversation with Multenius he and I arranged to buy and sell diamonds together here in London, and I at once paid over a sum of money to him as working capital. The transactions were carried out in his name. It was he, chiefly, who conducted them–he was as good and keen a judge of diamonds as any man I ever knew–and no one here was aware that I was concerned in them. I never went to his shop in Praed Street but twice–if it was absolutely necessary for him to see me, we met in the City, at a private office which I have there. Now you understand the exact relations between Daniel Multenius and myself. We were partners–in secret.

“We come, then, to recent events. Early in this present autumn, we heard from Mr. Stephen Purvis, with whom I had had some transactions in South Africa, that he had become possessed of a rare and fine orange-yellow diamond and that he was sending it to us. It arrived at Multenius’s– Multenius brought it to me at my city office and we examined it, after which Multenius deposited it in his bank. We decided to buy it ourselves –I finding the money. We knew, from our messages from Stephen Purvis, that he would be in town on the 18th November, and we arranged everything for that date. That date, then, becomes of special importance–what happened at Multenius’s shop in Praed Street on the afternoon of November 18th, between half-past four and half-past five is, of course, the thing that really is of importance. Now, what did happen? I can tell you–same as regards one detail which is, perhaps, of more importance than the other details. Of that detail I can’t tell anything–but I can offer a good suggestion about it.

“Stephen Purvis was to call at Daniel Multenius’s shop in Praed Street between five o’clock and half-past on the afternoon of November 18th–to complete the sale of his diamond. About noon on that day, Daniel Multenius went to the City. He went to his bank and took the diamond away. He then proceeded to my office, where I handed him eighty thousand pounds in bank notes–notes of large amounts. With the diamond and these notes in his possession, Daniel Multenius went back to Praed Street. I was to join him there shortly after five o’clock.

“Now we come to my movements. I lunched in the City, and afterwards went to a certain well-known book-seller’s in Holborn, who had written to tell me that he had for sale a valuable book which he knew I wanted. I have been a collector of rare books ever since I came back to England. I spent an hour or so at the book-seller’s shop. I bought the book which I had gone to see–paying a very heavy price for it. I carried it away in my hand, not wrapped up, and got into an omnibus which was going my way, and rode in it as far as the end of Praed Street. There I got out. And–in spite of what I said in my advertisement in the newspapers of the following morning,–I had the book in my hand when I left the omnibus. Why I pretended to have lost it, why I inserted that advertisement in the papers, I shall tell you presently–that was all part of a game which was forced upon me.

“It was, as near as I can remember, past five o’clock when I turned along Praed Street. The darkness was coming on, and there was a slight rain falling, and a tendency to fog. However, I noticed something–I am naturally very quick of observation. As I passed the end of the street which goes round the back of the Grand Junction Canal basin, the street called Iron Gate Wharf, I saw turn into it, walking very quickly, a Chinaman whom I knew to be one of the two Chinese medical students to whom Daniel Multenius had let a furnished house in Maida Vale. He had his back to me–I did not know which of the two he was. I thought nothing of the matter, and went on. In another minute I was at the pawn-shop. I opened the door, walked in, and went straight to the little parlour–I had been there just twice before when Daniel Multenius was alone, and so I knew my way. I went, I say, straight through–and in the parlour doorway ran into Stephen Purvis.

“Purvis was excited–trembling, big fellow though he is, do you see? He will bear me out as to what was said–and done. Without a word, he turned and pointed to where Daniel Multenius was lying across the floor–dead. ‘I haven’t been here a minute!’ said Purvis. ‘I came in–found him, like that! There’s nobody here. For God’s sake, where’s my diamond?’

“Now, I was quick to think. I formed an impression within five seconds. That Chinaman had called–found the old man lying in a fit, or possibly dead–had seen, as was likely, the diamond on the table in the parlour, the wad of bank-notes lying near, had grabbed the lot–and gone away. It was a theory–and I am confident yet that it was the correct one. And I tell you plainly that my concern from that instant was not with Daniel Multenius, but with the Chinaman! I thought and acted like lightning. First, I hastily examined Multenius, felt in his pockets, found that there was nothing there that I wanted and that he was dead. Then I remembered that on a previous visit of mine he had let me out of his house by a door at the rear which communicated with a narrow passage running into Market Street, and without a second’s delay, I seized Purvis by the arm and hurried him out. It was dark enough in that passage–there was not a soul about–we crossed Market Street, turned to the right, and were in Oxford and Cambridge Terrace before we paused. My instinct told me that the right thing to do was to get away from that parlour. And it was not until we were quite away from it that I realized that I had left my book behind me!”

CHAPTER THIRTY-FOUR

BAFFLED

Levendale paused at this point of his story, and looked round the circle of attentive faces. He was quick to notice that two men were watching him with particularly close attention–one was Ayscough, the other, the old solicitor. And as he resumed his account he glanced meaningly at Mr. Killick.

“I daresay some of you would like to question me–and Stephen Purvis, too –on what I’ve already told you?” he said. “You’re welcome to ask any questions you like–any of you–when I’ve done. But–let me finish–for then perhaps you’ll fully understand what we were at.

“Purvis and I walked up and down in Oxford and Cambridge Terrace for some time–discussing the situation. The more I considered the matter, the more I was certain that my first theory was right–the Chinaman had got the diamond and the banknotes. I was aware of these two Chinamen as tenants of Multenius’s furnished house–as a matter of fact, I had been present, at the shop in Praed Street, on one of my two visits there when they concluded their arrangements with him. What I now thought was this–one of them had called on the old man to do some business, or to pay the rent, and had found him in a fit, or dead, as the result of one, had seen the diamond and the money on the table, placed there in readiness for Purvis’s coming, and had possessed himself of both and made off. Purvis agreed with me. And–both Purvis and myself are well acquainted with the characteristic peculiarities, and idiosyncrasies of Chinamen!–we knew with what we had to deal. Therefore we knew what we had to do. We wanted the diamond and my money. And since we were uncomfortably aware of the craft and subtlety of the thief who’d got both we knew we should have to use craft ourselves–and of no common sort. Therefore we decided that the very last thing we should think of would be an immediate appeal to the police.

“Now, you police officials may, nay, will!–say that we ought to have gone straight to you, especially as this was a case of murder. But we knew nothing about it being a case of murder. We had seen no signs of violence on the old man–I knew him to be very feeble, and I believed he had been suddenly struck over by paralysis, or something of that sort. I reckoned matters up, carefully. It was plain that Daniel Multenius had been left alone in house and shop–that his granddaughter was out on some errand or other. Therefore, no one knew of the diamond and the money. We did not want any one to know. If we had gone to the police and told our tale, the news would have spread, and would certainly have reached the Chinaman’s ears. We knew well enough that if we were to get our property back the thief must not be alarmed–there must be nothing in the newspapers next morning. The Chinaman must not know that the real owners of the diamond and the banknotes suspected him–he must not know that information about his booty was likely to be given to the police. He must be left to believe–for some hours at any rate–that what he had possessed himself of was the property of a dead man who could not tell anything. But there was my book in that dead man’s parlour! It was impossible to go back and fetch it. It was equally impossible that it should not attract attention. Daniel Multenius’s granddaughter, whom I believed to be a very sharp young woman, would notice it, and would know that it had come into the place during her absence. I thought hard over that problem–and finally I drafted an advertisement and sent it off to an agency with instructions to insert it in every morning newspaper in London next day. Why? Because I wanted to draw a red herring across the trail!–I wanted, for the time being, to set up a theory that some man or other had found that book in the omnibus, had called in at Multenius’s to sell or pawn it, had found the old man alone, and had assaulted and robbed him. All this was with a view to hoodwinking the Chinaman. Anything must be done, anything!–to keep him ignorant that Purvis and I knew the real truth.

“But–what did we intend to do? I tell you, not being aware that old Daniel Multenius had met his death by violence, we did not give one second’s thought to that aspect and side of the affair–we concentrated on the recovery of our property. I knew the house in which these Chinese lived. That evening, Purvis and I went there. We have both been accustomed, in our time, to various secret dealings and manoeuvres, and we entered the grounds of that house without any one being the wiser. It did not take long to convince us that the house was empty. It remained empty that night–Purvis kept guard over it, in an outhouse in the garden. No one either entered or left it between our going to it and Purvis coming away from it next morning–he stayed there, watching until it was time to keep an appointment with me in Hyde Park. Before I met him, I had been called upon by Detective Ayscough, Mr. Rubinstein, and Mr. Lauriston–they know what I said to them. I could not at that time say anything else–I had my own concerns to think of.

“When Purvis and I met we had another consultation, and we determined, in view of all the revelations which had come out and had been published in the papers, that the suspicion cast on young Mr. Lauriston was the very best thing that could happen for us; it would reassure our Chinaman. And we made up our minds that the house in Maida Vale would not be found untenanted that night, and we arranged to meet there at eleven o’clock. We felt so sure that our man would have read all the news in the papers, and would feel safe, and that we should find him. But, mark you, we had no idea as to which of the two Chinamen it was that we wanted. Of one fact, however, we were certain–whichever it was that I had seen slip round the corner of Iron Gate Wharf the previous day, whether it was Chang Li or Chen Li, he would have kept his secret to himself! The thing was–to get into that house; to get into conversation with both; to decide which was the guilty man, and then–to take our own course. We knew what to do–and we went fully prepared.

“Now we come to this–our second visit to the house in Maida Vale. To be exact, it was between eleven and twelve on the second night after the disappearance of the diamond. As on the previous night, we gained access to the garden by the door at the back–that, on each occasion, was unfastened, while the gate giving access to the road in Maida Vale was securely locked. And, as on the previous night, we quickly found that up to then at any rate, the house was empty. But not so the garden! While I was looking round the further side of the house, Purvis took a careful look round the garden. And presently he came to me and drew away to the asphalted path which runs from the front gate to the front door. The moon had risen above the houses and trees–and in its light he pointed to bloodstains. It did not take a second look, gentlemen, to see that they were recent–in fact, fresh. Somebody had been murdered in that garden not many minutes–literally, minutes!–before our arrival. And within two minutes more we found the murdered man lying behind some shrubbery on the left of the path. I knew him for the younger of the two Chinese–the man called Chen Li.

“This discovery, of course, made us aware that we were now face to face with a new development. We were not long in arriving at a conclusion about that. Chang Li had found out that his friend had become possessed of these valuable–he might have discovered the matter of the diamond, or of the bank-notes or both–how was immaterial. But we were convinced, putting everything together, that he had made this discovery, had probably laid in wait for Chen Li as he returned home that night, had run a knife into him as he went up the garden, had dragged the body into the shrubbery, possessed himself of the loot, and made off. And now we were face to face with what was going, as we knew, to be the stiffest part of our work–the finding of Chang Li. We set to work on that without a moment’s delay.

“I have told you that Purvis and I have a pretty accurate knowledge of Chinamen; we have both had deep and intimate experience of them and their ways. I, personally, know a good deal of the Chinese Colony in London: I have done business with Chinamen, both in London and South Africa, for years. I had a good idea of what Chang Li’s procedure would be. He would hide–if need be, for months, until the first heat of the hue and cry which he knew would be sure to be raised, would have cooled down. There are several underground warrens–so to speak–in the East End, in which he could go to earth, comfortably and safely, until there was a chance of slipping out of the country unobserved. I know already of some of them. I would get to know of others.

“Purvis and I got on that track–such as it was, at once. We went along to the East End there and then–before morning I had shaved off my beard and mustache, disguised myself in old clothes, and was beginning my work. First thing next morning I did two things–one was to cause a telegram to be sent from Spring Street to my butler explaining my probable absence; the other to secretly warn the Bank of England about the bank-notes. But I had no expectation that Chang Li would try to negotiate those–all his energies, I knew, would be concentrated on the diamond. Nevertheless, he might try–and would, if he tried–succeed–in changing one note, and it was as well to take that precaution.

“Now then, next day, Purvis and I being, in our different ways, at work in the East End, we heard the news about the Praed Street tradesman, Parslett. That seemed to me remarkable proof of my theory. As the successive editions of the newspapers came out during that day, and next day, we learnt all about the Parslett affair. I saw through it at once. Parslett, being next-door neighbour to Daniel Multenius, had probably seen Chen Li–whom we now believed to have been the actual thief–slip away from Multenius’s door, and, when the news of Daniel’s death came out, had put two and two together, and, knowing where the Chinamen lived, had gone to the house in Maida Vale to blackmail them. I guessed what had happened then–Parslett, to quieten him for the moment, had been put off with fifty pounds in gold, and promised more–and he had also been skilfully poisoned in such a fashion that he would get safely away from the premises but die before he got home. And when he was safe away, Chang Li had murdered Chen Li, and made off. So–as I still think–all our theories were correct, and the only thing to do was to find Chang.”

But here Levendale paused, glanced at Stephen Purvis, and spread out his hands with a gesture which indicated failure and disappointment. His glance moved from Stephen Purvis to the police officials.

“All no good!” he exclaimed. “It’s useless to deny it. I have been in every Chinese den and haunt in East London–I’m certain that Chang Li is nowhere down there. I have spent money like water–employed Chinese and Easterns on whom I could depend–there isn’t a trace of him! And so–we gave up last night. Purvis and I–baffled. We’ve come to you police people–“

“You should have done that before, Mr. Levendale,” said the Inspector severely. “You haven’t given us much credit, I think, and if you’d told all this at first–“

Before the Inspector could say more, a constable tapped at the door and put his head into the room. His eyes sought Ayscough.

“There’s a young gentleman–foreigner–asking for you, Mr. Ayscough,” he said. “Wants to see you at once–name of Mr. Yada.”

CHAPTER THIRTY-FIVE

YADA TAKES CHARGE

Ayscough had only time to give a warning look and a word to the others before Mr. Mori Yada was ushered in. Every eye was turned on him as he entered–some of the men present looking at him with wonder, some with curiosity, two, at any rate–Levendale and Stephen Purvis–with doubt. But Yada himself was to all outward appearance utterly indifferent to the glances thrown in his direction: it seemed to John Purdie, who was remembering all he had heard the night before, that the young Japanese medical student was a singularly cool and self-possessed hand. Yada, indeed, might have been walking in on an assemblage of personal friends, specially gathered together in his honour. Melky Rubinstein, who was also watching him closely, noticed at once that he had evidently made a very careful toilet that morning. Yada’s dark overcoat, thrown negligently open, revealed a smart grey lounge suit; in one gloved hand he carried a new bowler hat, in the other a carefully rolled umbrella. He looked as prosperous and as severely in mode as if no mysteries and underground affairs had power to touch him, and the ready smile with which he greeted Ayscough was ingenuous and candid enough to disarm the most suspicious.

“Good morning, Mr. Detective,” he began, as he crossed the threshold and looked first at Ayscough and then at the ring of attentive faces. “I want to speak to you on that little affair of last night, you know. I suppose you are discussing it with these gentlemen? Well, perhaps I can now give you some information that will be useful.”

“Glad to hear anything, Mr. Yada,” said Ayscough, who was striving hard to conceal his surprise. “Anything that you can tell us. You’ve heard something during the night, then?”

Yada laughed pleasantly, showing his white teeth. He dropped into the chair which Ayscough pushed forward, and slowly drew off his gloves.

“I assured myself of something last night–after you left me,” he said, with a knowing look. “I used your card to advantage, Mr. Detective. I went to the mortuary.”

Ayscough contrived to signal to the Inspector to leave the talking to him. He put his thumbs in the armholes of his waistcoat, assumed an easy attitude as he leaned against the door, and looked speculatively at the new comer.

“Aye?–and what made you do that now, Mr. Yada?” he asked, half- carelessly. “A bit of curiosity, eh?”

“Not idle curiosity, Mr. Detective,” replied Yada. “I wanted to know, to make certain, which of the two Chinamen it really was who was there–dead. I saw him. Now I know. Chen Li!”

“Well?” said Ayscough.

Yada suddenly twisted round in his chair, and slowly glanced at the listening men on either side of the desk. They were cool, bold, half- insolent eyes which received face after face, showing no recognition of any until they encountered Melky Rubinstein’s watchful countenance. And to Melky, Yada accorded a slight nod–and turned to Ayscough again.

“Which,” he asked calmly, “which of these gentlemen is the owner of the diamond? Which is the one who has lost eighty thousand pounds in bank- notes? That is what I want to know before I say more.”

In the silence which followed upon Ayscough’s obvious doubt about answering this direct question, Levendale let out a sharp, half-irritable exclamation:

“In God’s name!” he said, “who is this young man? What does he know about the diamond and the money?”

Yada turned and faced his questioner–and suddenly smiling, thrust his hand in his breast pocket and drew out a card-case. With a polite bow he handed a card in Levendale’s direction.

“Permit me, sir,” he said suavely. “My card. As for the rest, perhaps Mr. Detective here will tell you.”

“It’s this way, you see, Mr. Levendale,” remarked Ayscough. “Acting on information received from Dr. Pittery, one of the junior house-surgeons at University College Hospital, who told me that Mr. Yada was a fellow- student of those two Chinese, and a bit of a friend of theirs, I called on Mr. Yada last night to make enquiries. And of course I had to tell him about the missing property–though to be sure, that’s news that’s common to everybody now–through the papers. And–what else have you to tell, Mr. Yada?”

But Yada was watching Levendale–who, on his part, was just as narrowly watching Yada. The other men in the room watched these two–recognizing, as if by instinct, that from that moment matters lay between Levendale and Yada, and not between Yada and Ayscough. They were mutually inspecting and appraising each other, and in spite of their impassive faces, it was plain that each was wondering about his next move.

It was Levendale who spoke first–spoke as if he and the young Japanese were the only people in the room, as if nothing else mattered. He bent forward to Yada.

“How much do you know?” he demanded.

Yada showed his white teeth again.

“A plain–and a wide question, Mr. Levendale!” he answered, with a laugh. “I see that you are anxious to enlist my services. Evidently, you believe that I do know something. But–you are not the owner of the diamond! Which of these gentlemen is?”

Levendale made a half impatient gesture towards Stephen Purvis, who nodded at Yada but remained silent.

“He is!” said Levendale, testily. “But you–can do your talking to me. Again–how much do you know in this matter?”

“Enough to make it worth your while to negotiate with me,” answered Yada. “Is that as plain as your question?”

“It’s what I expected,” said Levendale. “You want to sell your knowledge.”

“Well?” assented Yada, “I am very sure you are willing to purchase.”

Once more that duel of the eyes–and to John Purdie, who prided himself on being a judge of expressions, it was evident that the younger man was more than the equal of the older. It was Levendale who gave way–and when he took his eyes off Yada, it was to turn to Stephen Purvis.

Stephen Purvis nodded his head once more–and growled a little.

“Make terms with him!” he muttered. “Case of have to, I reckon!”

Levendale turned once more to the Japanese, who smiled on him.

“Look you here, Mr. Yada,” said Levendale, “I don’t know who you are beyond what I’m told–your card tells me nothing except that you live– lodge, I suppose–in Gower Street. You’ve got mixed up in this, somehow, and you’ve got knowledge to dispose of. Now, I don’t buy unless I know first what it is I’m buying. So–let’s know what you’ve got to sell?”

Yada swept the room with a glance.

“Before these gentlemen?” he asked. “In open market, eh?”

“They’re all either police, or detectives, or concerned,” retorted Levendale. “There’s no secret. I repeat–what have you got to sell? Specify it!”

Yada lifted his hands and began to check off points on the tips of his fingers.

“Three items, then, Mr. Levendale,” he replied cheerfully. “First–the knowledge of who has got the diamond and the money. Second–the knowledge of where he is at this moment, and will be for some hours. Third–the knowledge of how you can successfully take him and recover your property. Three good, saleable items, I think–yes?”

Purdie watched carefully for some sign of greed or avarice in the informer’s wily countenance. To his surprise, he saw none. Instead, Yada assumed an almost sanctimonious air. He seemed to consider matters–though his answer was speedy.

“I don’t want to profit–unduly–by this affair,” he said. “At the same time, from all I’ve heard, I’m rendering you and your friend a very important service, and I think it only fair that I should be remunerated. Give me something towards the expenses of my medical education, Mr. Levendale: give me five hundred pounds.”

With the briefest exchange of glances with Stephen Purvis, Levendale pulled out a cheque-book, dashed off a cash cheque, and handed it over to the Japanese, who slipped it into his waistcoat pocket.

“Now–your information!” said Levendale.

“To be sure,” replied Yada. “Very well. Chang Li has the diamond and the money. And he is at this moment where he has been for some days, in hiding. He is in a secret room at a place called Pilmansey’s Tea Rooms, in Tottenham Court Road–a place much frequented by medical students from our college. The fact of the case is, Mr. Policeman, and the rest of you generally, there is a secret opium den at Pilmansey’s, though nobody knows of it but a few frequenters. And there!–there you will find Chang Li.”

“You’ve seen him there?” demanded Levendale.

“I saw him there during last night–I know him to be there–he will be there, either until you take him, or until his arrangements are made for getting out of this country,” answered Yada.

Levendale jumped up, as if for instant action. But the Inspector quietly tapped him on the elbow.

“He promised to tell you how to take him, Mr. Levendale,” he said. “Let’s know all we can–we shall have to be in with you on this, you know.”

“Mr. Police-Inspector is right,” said Yada. “You will have to conduct what you call a raid. Now, do precisely what I tell you to do. Pilmansey’s is an old-fashioned place, a very old house as regards its architecture, on the right-hand side of Tottenham Court Road. Go there today–this mid-day –a little before one–when there are always plenty of customers. Go with plenty of your plain-clothes men, like Mr. Ayscough there. Drop in, don’t you see, as if you were customers–let there be plenty of you, I repeat. There are two Pilmanseys–men–middle-aged, sly, smooth, crafty men. When you are all there, take your own lines–close the place, the doors, if you like–but get hold of the Pilmansey men, tell them you are police, insist on being taken to the top floor and shown their opium den. They will object, they will lie, they will resist–you will use your own methods. But–in that opium den you will find Chang Li–and your property!”

He had been drawing on his gloves as he spoke, and now, picking up his hat and umbrella, Yada bowed politely to the circle and moved to the door.

“You will excuse me, now?” he said. “I have an important lecture at the medical school which I must not miss. I shall be at Pilmansey’s, myself, a little before one–please oblige me by not taking any notice of me. I do not want to figure–actively–in your business.”

Then he was gone–and the rest of them were so deeply taken with the news which he had communicated that no one noticed that just before Yada fastened his last glove-button, Melky Rubinstein slipped from his corner and glided quietly out of the room.

CHAPTER THIRTY-SIX

PILMANSEY’S TEA ROOMS

Two hours later, it being then a quarter-to-one o’clock, Purdie and Lauriston got out of a taxi-cab at the north-end of Tottenham Court Road and walked down the right-hand side of that busy thoroughfare, keeping apparently careless but really vigilant eyes open for a first glimpse of the appointed rendezvous. But Pilmansey’s Tea Rooms required little searching out. In the midst of the big modern warehouses, chiefly given up to furniture and upholstery, there stood at that time a block of old property which was ancient even for London. The buildings were plainly early eighteenth century: old redbrick erections with narrow windows in the fronts and dormer windows in the high, sloping roofs. Some of them were already doomed to immediate dismantlement; the tenants had cleared out, there were hoardings raised to protect passers-by from falling masonry, and bills and posters on the threatened walls announced that during the rebuilding, business would be carried on as usual at some other specified address. But Pilmansey’s, so far, remained untouched, and the two searchers saw that customers were going in and out, all unaware that before evening their favourite resort for a light mid-day meal would attain a fame and notoriety not at all promised by its very ordinary and commonplace exterior.

“An excellent example of the truth of the old saying that you should never judge by appearances, Andie, my man!” remarked Purdie, as they took a quick view of the place. “Who’d imagine that crime, dark secrets, and all the rest of it lies concealed behind this?–behind the promise of tea and muffins, milk and buns! It’s a queer world, this London!–you never know what lies behind any single bit of the whole microcosm. But let’s see what’s to be seen inside.”

The first thing to be seen inside the ground floor room into which they stepped was the man from New Scotland Yard, who, in company with another very ordinary-looking individual was seated at a little table just inside the entrance, leisurely consuming coffee and beef sandwiches. He glanced at the two men as if he had never seen them in his life, and they, preserving equally stolid expressions with credit if not with the detective’s ready and trained ability, passed further on–only to recognize Levendale and Stephen Purvis, who had found accommodation in a quiet corner half-way down the room. They, too, showed no signs of recognition, and Purdie, passing by them, steered his companion to an unoccupied table and bade him be seated.

“Let’s get our bearings,” he whispered as they dropped into their seats. “Looks as innocent and commonplace within as it appeared without, Andie. But use your eyes–it ought to make good copy for you, this.”

Lauriston glanced about him. The room in which they sat was a long, low- ceiling apartment, extending from the street door to a sort of bar-counter at the rear, beyond which was a smaller room that was evidently given up to store and serving purposes. On the counter were set out provisions– rounds of beef, hams, tongues, bread, cakes, confectionery; behind it stood two men whom the watchers at once set down as the proprietors. Young women, neatly gowned in black and wearing white caps and aprons, flitted to and fro between the counter and the customers. As for the customers they were of both sexes, and the larger proportion of them young. There was apparently no objection to smoking at Pilmansey’s–a huge cloud of blue smoke ascended from many cigarettes, and the scent of Turkish tobacco mingled with the fragrance of freshly-ground coffee. It was plain that Pilmansey’s was the sort of place wherein you could get a good sandwich, good tea or coffee, smoke a cigarette or two, and idle away an hour in light chatter with your friends between your morning and afternoon labours.

But Lauriston’s attention was mainly directed to the two men who stood behind the bar-counter, superintending and directing their neat assistants. Sly, smooth, crafty men–so they had been described by Mr. Mori Yada: Lauriston’s opinion coincided with that of the Japanese, on first, outer evidence and impression. They were middle-aged, plump men who might be, and probably were, twins, favouring mutton chop whiskers, and good linen and black neckcloths–they might have been strong, highly- respectable butlers. Each had his coat off; each wore a spotless linen apron; each wielded carving knives and forks; each was busy in carving plates of ham or tongue or beef; each contrived, while thus engaged, to keep his sharp, beady eyes on the doings in the room in front of the counter. Evidently a well-to-do, old-established business, this, and highly prosperous men who owned it: Lauriston wondered that they should run any risks by hiding away a secret opium den somewhere on their ancient premises.

In the midst of their reflections one of the waitresses came to the table at which the two friends sat: Lauriston quicker of wit than Purdie in such matters immediately ordered coffee and sandwiches and until they came, lighted a cigarette and pretended to be at ease, though he was inwardly highly excited.

“It’s as if one were waiting for an explosion to take place!” he muttered to Purdie. “Even now I don’t know what’s going to happen.”

“Here’s Ayscough, anyway,” said Purdie. “He looks as if nothing was about to happen.”

Ayscough, another man with him, was making his way unconcernedly down the shop. He passed the man from New Scotland Yard without so much as a wink: he ignored Levendale and Stephen Purvis; he stared blankly at Purdie and Lauriston, and led his companion to two vacant seats near the counter. And they had only just dropped into them when in came Mr. Killick, with John Purvis and Guyler and slipped quietly into seats in the middle of the room. Here then, said Lauriston to himself, were eleven men, all in a secret–and there were doubtless others amongst the company whom he did not know.

“But where’s Melky Rubinstein?” he whispered suddenly. “I should have thought he’d have turned up–he’s been so keen on finding things out.”

“There’s time enough yet,” answered Purdie. “It’s not one. I don’t see the Jap, either. But–here’s the Inspector–done up in plain clothes.”

The Inspector came in with a man whom neither Purdie nor Lauriston had ever seen before–a quietly but well-dressed man about whom there was a distinct air of authority. They walked down the room to a table near the counter, ordered coffee and lighted cigarettes–and the two young Scotsmen, watching them closely, saw that they took a careful look round as if to ascertain the strength of their forces. And suddenly, as Lauriston was eating his second sandwich, the Inspector rose, quietly walked to the counter and bending over it, spoke to one of the white- aproned men behind.
