particulars relating to the diamonds, and laid it on the parcel before he closed up the safe."
"Was anyone present when Mr. Hornby opened the safe in the morning?" asked Thorndyke.
"No, he was alone," answered the lawyer. "He saw at a glance that the diamonds were missing, and then he observed the paper with the thumb-mark on it, on which he closed and locked the safe and sent for the police."
"Is it not rather odd that the thief did not notice the thumb-mark, since it was so distinct and conspicuous?"
"No, I think not," answered Mr. Lawley. "The paper was lying face downwards on the bottom of the safe, and it was only when he picked it up and turned it over that Mr. Hornby discovered the thumb-print. Apparently the thief had taken hold of the parcel, with the paper on it, and the paper had afterwards dropped off and fallen with the marked surface downwards--probably when the parcel was transferred to the other hand."
"You mentioned," said Thorndyke, "that the experts at Scotland Yard have identified this thumb-mark as that of Mr. Reuben Hornby. May I ask how they came to have the opportunity of making the comparison?"
"Ah!" said Mr. Lawley. "Thereby hangs a very curious tale of coincidences. The police, of course, when they found that there was so simple a means of identification as a thumb-mark, wished to take thumb-prints of all the employees in the works; but this Mr. Hornby refused to sanction--rather quixotically, as it seems to me--saying that he would not allow his nephews to be subjected to such an indignity. Now it was, naturally, these nephews in whom the police were chiefly interested, seeing that they alone had had the handling of the keys, and considerable pressure was brought to bear upon Mr. Hornby to have the thumb-prints taken.
"However, he was obdurate, scouting the idea of any suspicion attaching to either of the gentlemen in whom he had reposed such complete confidence and whom he had known all their lives, and so the matter would probably have remained a mystery but for a very odd circumstance.
"You may have seen on the bookstalls and in shop windows an appliance called a 'Thumbograph,' or some such name, consisting of a small book of blank paper for collecting the thumb-prints of one's friends, together with an inking pad."
"I have seen those devices of the Evil One," said Thorndyke, "in fact, I have one, which I bought at Charing Cross Station."
"Well, it seems that some months ago Mrs. Hornby, the wife of John Hornby, purchased one of these toys--" "As a matter of fact," interrupted Reuben, "it was my cousin Walter who bought the thing and gave it to her."
"Well, that is not material," said Mr. Lawley (though I observed that Thorndyke made a note of the fact in his book); "at any rate, Mrs. Hornby became possessed of one of these appliances and proceeded to fill it with the thumb-prints of her friends, including her two nephews. Now it happened that the detective in charge of this case called yesterday at Mr. Hornby's house when the latter was absent from home, and took the opportunity of urging her to induce her husband to consent to have the thumb-prints of her nephews taken for the inspection of the experts at Scotland Yard. He pointed out that the procedure was really necessary, not only in the interests of justice but in the interests of the young men themselves, who were regarded with considerable suspicion by the police, which suspicion would be completely removed if it could be shown by actual comparison that the thumb-print could not have been made by either of them. Moreover, it seemed that both the young men had expressed their willingness to have the test applied, but had been forbidden by their uncle. Then Mrs. Hornby had a brilliant idea. She suddenly remembered the 'Thumbograph,' and thinking to set the question at rest once for all, fetched the little book and showed it to the detective. It contained the prints of both thumbs of Mr. Reuben (among others), and, as the detective had with him a photograph of the incriminating mark, the comparison was made then and there; and you may imagine Mrs. Hornby's horror and amazement when it was made clear that the print of her nephew Reuben's left thumb corresponded in every particular with the thumb-print that was found in the safe.
"At this juncture Mr. Hornby arrived on the scene and was, of course, overwhelmed with consternation at the turn events had taken. He would have liked to let the matter drop and make good the loss of the diamonds out of his own funds, but, as that would have amounted practically to compounding a felony, he had no choice but to prosecute. As a
