“I understand that you are the officer in charge of the Marbury murder case,” he observed. “I believe I can give you some valuable information in respect to that. I read the account of the affair in the _Watchman_ newspaper this morning, and saw the portrait of the murdered man there, and I was at first inclined to go to the _Watchman_ office with my information, but I finally decided to approach the police instead of the Press, regarding the police as being more—more responsible.” “Much obliged to you, sir,” said Rathbury, with a glance at Spargo. “Whom have I the pleasure of——” “My name,” replied the visitor, drawing out and laying down a card, “is Myerst—Mr. E.P. Myerst, Secretary of the London and Universal Safe Deposit Company. I may, I suppose, speak with confidence,” continued Mr. Myerst, with a side-glance at Spargo. “My information is—confidential.” Rathbury inclined his head and put his fingers together. “You may speak with every confidence, Mr. Myerst,” he answered. “If what you have to tell has any real bearing on the Marbury case, it will probably have to be repeated in public, you know, sir. But at present it will be treated as private.” “It has a very real bearing on the case, I should say,” replied Mr. Myerst. “Yes, I should decidedly say so. The fact is that on June 21st at about—to be precise—three o’clock in the afternoon, a stranger, who gave the name of John Marbury, and his present address as the Anglo-Orient Hotel, Waterloo, called at our establishment, and asked if he could rent a small safe. He explained to me that he desired to deposit in such a safe a small leather box—which, by the by, was of remarkably ancient appearance—that he had brought with him. I showed him a safe such as he wanted, informed him of the rent, and of the rules of the place, and he engaged the safe, paid the rent for one year in advance, and deposited his leather box—an affair of about a foot square—there and then. After that, having exchanged a remark or two about the altered conditions of London, which, I understood him to say, he had not seen for a great many years, he took his key and his departure. I think there can be no doubt about this being the Mr. Marbury who was found murdered.” “None at all, I should say, Mr. Myerst,” said Rathbury. “And I’m much obliged to you for coming here. Now you might tell me a little more, sir. Did Marbury tell you anything about the contents of the box?” “No. He merely remarked that he wished the greatest care to be taken of it,” replied the secretary. “Didn’t give you any hint as to what was in it?” asked Rathbury. “None. But he was very particular to assure himself that it could not be burnt, nor burgled, nor otherwise molested,” replied Mr. Myerst. “He appeared to be greatly relieved when he found that it was impossible for anyone but himself to take his property from his safe.”
