"No!" replied Allerdyke. "Never. But I should say it's a foreigner's."
"Very likely," assented Chettle. "Aye, well, sir, it lured the man to his death. And now I'll show you where he died, and how easy it was for the murderer to kill him and get away unobserved."
He pulled the cab up at the corner of the High Street, and turned southward towards the river, looking round at his companion with one of his sly smiles.
"I daresay that you, being a Yorkshireman, Mr. Allerdyke, know all about this old street," he remarked as they walked forward. "I never saw it, never heard of it, until the other day, when I was sent down on this Lydenberg business, but it struck me at once. I should think it's one of the oldest streets left in England."
"It is," answered Allerdyke. "I know it well enough, and I've seen it changed. It used to be the street of the old Hull merchants—they had their houses and warehouses all combined, with gardens at the back running down to the river Hull. Queer old places there used to be in this street, I can tell you when I was a lad!—of late years they've pulled a lot of property down that had got what you might call thoroughly worm-eaten—oh, yes, the place isn't half as ancient or picturesque as it was even twenty years ago!"
"There's plenty of the ancient about it still, for all that," observed Chettle, with a dry laugh. "There was more than enough of it for Lydenberg the other day, at any rate. Now, then, you remember what it said on the postcard—he was to walk down the High Street, on the left-hand side, at eleven o'clock? Very well—down the High Street he walks, on this side which we are now—he strolls along, by these old houses, looking about him, of course, for the person he was to meet. The few people who were about down here that morning, and who saw him, said that he was looking about from side to side. And all of a sudden a shot rang out, and Lydenberg fell—just here—right on this very pavement."
He pulled Allerdyke up in a narrow part of the old street, jointed to the flags, and then to the house behind them—an ancient, ramshackle place, the doors and windows of which were boarded up, the entire fabric of which showed unmistakable readiness for the pick and shovel of the house-breaker. And he laid a hand on one of the shattered windows, close by a big hole in the decaying wood.
"There's no doubt the murderer was hidden behind this shutter, and that he fired at Lydenberg from it, through this hole," he said. "So, you see, he'd only be a few feet from his man. He was evidently a good shot, and a fellow of resolute nerve, for he made no mistake. He only fired once, but he shot Lydenberg clean through the heart, dead!"
"Anybody see it happen?" asked Allerdyke, staring about him at the scene of the tragedy, and thinking how very ordinary and commonplace everything looked. "I suppose there'd be people about, though the street, at this end, anyway, isn't as busy as it once was?"
"Several people saw him fall," answered Chettle.
"They say he jumped, spun round, and fell across the pavement. And they all thought it was a case of suicide. That, of course, gave the murderer a bigger and better chance of making off. You see, as these people saw no assailant, it never struck 'em that the shot had been fired from behind this window. When they collected their thoughts, found it wasn't suicide, and realized that it was murder, the murderer was—Lord knows where! From behind these old houses, Mr. Allerdyke, there's a perfect rabbit-warren of alleys, courts, slums, twists, and turns! The man could slip out at the back, go left or right, mix himself up with the crowd on the quays and wharves, walk into the streets, go anywhere—all in a minute or two."
"Clever—very clever! You've no clue?" asked Allerdyke.
"None; not a scrap!" replied the detective. "Bless you, there's score of foreigners knocking about Hull. Scores! Hundreds! We've done all we can, the local police and myself—we've no clue whatever. But, of course, it was done by one of the gang."
"By one of the gang!" exclaimed Allerdyke. "Ah you've got a theory of your own, then?"
Chettle laughed quietly as they turned and retraced their steps up the street.
"It 'ud be queer if I hadn't, by this time," he answered. "Oh yes, I've thought things out pretty well, and I should say our people at the Yard have come to the same conclusion that I have—I'm not conceited enough, Mr. Allerdyke, to fancy that I'm the only person who's arrived at a reasonable theory, not I?"
"Well—what is your theory?" asked Allerdyke.
"This," replied the detective. "The whole thing, the theft of the Princess Nastirsevitch's jewels from your cousin, of Miss de Longarde's or Lennard's jewels, was the work of a peculiarly clever gang—though it may be of an individual—who made use of both Lydenberg and the French maid as instruments, and subsequently murdered those two in order to silence them forever. I say it may be the work of an individual—it's quite possible that the man who killed the Frenchwoman is also the man who shot Lydenberg—but it may be the work of one, two, or three separate persons, acting in collusion. I believe that Lydenberg was the actual thief of the Princess's jewels from your cousin; that the Frenchwoman actually stole her mistress's jewels. But as to how it was worked—as to who invented and carried out the whole thing—ah!"
"And to that—to the real secret of the whole matter—we haven't the ghost of a clue!" muttered Allerdyke. "That's about it, eh?"
Chettle laughed—a sly, suggestive laugh. He gave his companion one of his half-apologetic looks.
"I'm not so sure, Mr. Allerdyke," he said. "We may have—and that's why I wanted to see you by yourself. Come round to the police-station."
In a quiet room in the usual drab and dismal atmosphere which Allerdyke was beginning to associate with police affairs, Chettle produced the personal property of the dead man, all removed, he said, from the Station Hotel, for safe keeping.
"There's little to go on, Mr. Allerdyke," he said, pointing to one article after another. "You'll remember that the man represented himself as being a Norwegian doctor, who had come to Hull on private business. He may have been that—we're making inquiries about him in Christiania, where he hailed from. According to those who're in a position to speak, his clothing, linen, boots, and so on are all of the sort you'd get in that country. But he'd no papers on him to show his business, no private letters, no documents connecting him with Hull in any way: he hadn't even a visiting-card. He'd a return ticket—from Hull to Christiania—and he'd plenty of money, English and foreign. When I got down here, I helped the local police to go through everything—we even searched the linings of his clothing and ripped his one handbag to pieces. But we've found no more than I've said. However—I've found something. Nobody knows that I've found it. I haven't told the people here—I haven't even reported it to headquarters in London. I wanted you to see it before I spoke of it to a soul. Look here!"
Chettle opened a square cardboard box in which certain personal effects belonging to Lydenberg had been placed—one or two rings, a pocket-knife, his purse and its contents, a cigar-case, his watch and chain. He took up the watch, detached it from the chain, and held it towards Allerdyke, who was regarding these proceedings with intense curiosity.
"You see this watch, Mr. Allerdyke," he said. "It's a watch of foreign make—Swiss—and it's an old one, a good many years old, I should say. Consequently, it's a bit what we might call massive. Now, I was looking at it yesterday—late last night, in fact—and an idea suddenly struck me. In consequence of that idea, I opened the back of the watch, and discovered—that!"
He snapped open the case of the watch as he spoke and showed Allerdyke, neatly cut out to a circle, neatly fitted into the case, a photograph—the photograph of James Allerdyke! And Allerdyke started as if he had been shot, and let out a sharp exclamation.
"My God!" he cried. "James! James, by all that's holy—and in there!"
"You recognize it, of course?" said Chettle, with a grim smile. "No doubt of it, eh?"
"Doubt! Recognize!" exclaimed Allerdyke. "Lord, man—why, I took it myself, not two months ago!"
CHAPTER XVIII
DEFINITE SUSPICION
Chettle laughed—a low, suggestive, satisfied chuckle. He laid the watch, its case still open, on the table at which they were standing, and tapped the photograph with the point of his finger.
"That may be the first step to the scaffold—for somebody," he said, with a meaning glance. "Ah—it's extraordinary what little, innocent-looking things help to put a bit of rope round a man's neck! So you took this, Mr. Allerdyke?—took it yourself, you say?"
"Took it myself, some eight or nine weeks ago," answered Allerdyke. "I took it in my garden one Sunday afternoon when my cousin James happened to be there. I do a bit in that way—amusement, you know. I just chanced to have a camera in my hand, and I saw James in a very favourable light and position, and I snapped him. And it was such a good 'un when developed that I printed off a few copies."
The detective's face became anxious.
"How many, now?" he asked. "How many, Mr. Allerdyke? I hope you can remember?—it's a point of the utmost seriousness."
"Naught easier," answered Allerdyke readily. "I've a good memory for little things as well as big 'uns. I printed off four copies. One of 'em I pasted into an album in which I keep particularly good photographs of my own taking; the other three I gave to him—he put 'em in his pocket-book."
"All unmounted—like this?" asked Chettle.
"All unmounted—like that," affirmed Allerdyke. "And now, then, since it seems to be a matter of importance, I can tell you what James did with at any rate two of 'em. He gave one to our cousin Grace—Mrs. Henry Mallins—a Bradford lady. He gave another to a friend of my own, another amateur photographer, Wilson Firth—gave him it in my presence at the Midland Hotel one day, when we were all three having a cigar together in the smoking-room there. Wilson Firth's a bit of a rival of mine in the amateur photographic line—we each try to beat the other, you understand. Now, then, James pulled one of these snapshots out and handed it over to Wilson with a laugh. 'There,' he says, 'that's our Marshall's latest performance—you'll have a job to do aught better than that, Wilson, my lad,' he says. So that accounts for two. And—this is the third!"
"And the question, Mr. Allerdyke, the big question—a most important question!—is, how did it come into this man Lydenberg's possession?" said the detective anxiously. "If we can find that out—"
"I've been thinking," interrupted Allerdyke. "There's this about it, you know: James and this Lydenberg came over together from Christiania to Hull in the Perisco. They talked to one another—that's certain. James may have given it to Lydenberg. But the thing is—is that likely?"
"No!" replied Chettle, with emphatic assurance. "No, sir! And I'll tell you why. If your cousin had given this photo to Lydenberg, as he might, of course, have given it to a mere passing acquaintance, because that acquaintance took a fancy to it, or something of that sort, Lydenberg would in all reasonable probability have just slipped in into his pocket-book, or put it loose amongst his letters and papers. But, as we see, however Lydenberg became possessed of this photo, he took unusual pains and precautions about it. You see, he cut it down, most carefully and neatly, to fit into the cover of his watch—he took the trouble to carry it where no one else would see it, but where he could see it himself at a second's notice—he'd nothing to do but to snap open that cover. No, sir, your cousin didn't give that photo to Lydenberg. That photo was sent to Lydenberg, Mr. Allerdyke—sent! And it was sent for one purpose only. What? That he should be able to identify Mr. James Allerdyke as soon as he set eyes on him!"
Allerdyke nodded his head—in complete understanding and affirmation. He was thinking the same thing—thinking, too, that here was at least a clue, a real tangible clue.
"Aye!" he said. "I agree with you. Then, of course, the one and only thing to do is—"
"To find out who the person was that your cousin gave this particular print to!" said Chettle eagerly. "Of course, it's a big field. So far as I understand things, he'd been knocking round a good bit between the time of your taking this photo and his death. He'd been in London, hadn't he? And in Russia—in two or three places. How can we find out when and how he parted with this? For give it to somebody he did, and that somebody was a person who knew of the jewel transaction, and employed Lydenberg in it, and sent the photo to Lydenberg so that he should know your cousin by sight—at once. Mr. Allerdyke, the secret of these murders and thefts is—there!"
Chettle replaced the watch in the cardboard box from which he had taken it, produced a bit of sealing-wax from his pocket, sealed up the box, and put it and the other things belonging to Lydenberg back in the small trunk from which he had withdrawn them to show his companion. And Allerdyke watched him in silence, wondering and speculating about this new development.
"What do you want me to do?" he asked suddenly. "You've got some scheme, of course, or you wouldn't have got me down here alone."
"Just so," agreed Chettle. "I have a scheme—and that's why I did get you down here alone. Mr. Allerdyke, you're a sharp, shrewd man—all you Yorkshiremen are!—at least, all that I've ever come across. You're good hands at ferreting things out. Now, Mr. Allerdyke, let's be plain—there's no two ways about it, no doubt whatever of it, the only people in England that we're aware of who knew about this Nastirsevitch jewel transaction are—Fullaway and whoever he has in his employ! We know of nobody else—unless, indeed, it's the Chicago millionaire, Delkin, and he's not very likely to have wanted to go in for a job of this sort. No, sir—Fullaway is the suspected person, in my opinion!—though I'm going to take precious good care to keep that opinion to myself yet awhile, I can tell you. Fullaway, Mr. Allerdyke, Fullaway!"
"Well?" demanded Allerdyke. "And so—"
"And so I want you to use your utmost ingenuity to find out if your cousin James gave that photo to Fullaway," continued Chettle. "We know very well that he was in touch with Fullaway before he went off to Russia—I have it in my notes that when Fullaway came to see you here in Hull, at the Station Hotel, the day of your cousin's death, he told you that he and Mr. James Allerdyke had been doing business for a couple of years, and that they'd last met in London about the end of March, just before your cousin set off on his journey to Russia. Is that correct?"
