Rathbury leaned back in his chair in his apparently favourite attitude and stared hard at the dusty ceiling above him.
"Don't know," he said. "It brings things up to a point, certainly. Aylmore and Marbury parted at Waterloo Bridge—very late. Waterloo Bridge is pretty well next door to the Temple. But—how did Marbury get into the Temple, unobserved? We've made every enquiry, and we can't trace him in any way as regards that movement. There's a clue for his going there in the scrap of paper bearing Breton's address, but even a Colonial would know that no business was done in the Temple at midnight, eh?"
"Well," said Spargo, "I've thought of one or two things. He may have been one of those men who like to wander around at night. He may have seen—he would see—plenty of lights in the Temple at that hour; he may have slipped in unobserved—it's possible, it's quite possible. I once had a moonlight saunter in the Temple myself after midnight, and had no difficulty about walking in and out, either. But—if Marbury was murdered for the sake of what he had on him—how did he meet with his murderer or murderers in there? Criminals don't hang about Middle Temple Lane."
The detective shook his head. He picked up his pencil and began making more hieroglyphics.
"What's your theory, Mr. Spargo?" he asked suddenly. "I suppose you've got one."
"Have you?" asked Spargo, bluntly.
"Well," returned Rathbury, hesitatingly, "I hadn't, up to now. But now—now, after what you've told me, I think I can make one. It seems to me that after Marbury left Aylmore he probably mooned about by himself, that he was decoyed into the Temple, and was there murdered and robbed. There are a lot of queer ins and outs, nooks and corners in that old spot, Mr. Spargo, and the murderer, if he knew his ground well, could easily hide himself until he could get away in the morning. He might be a man who had access to chambers or offices—think how easy it would be for such a man, having once killed and robbed his victim, to lie hid for hours afterwards? For aught we know, the man who murdered Marbury may have been within twenty feet of you when you first saw his dead body that morning. Eh?"
Before Spargo could reply to this suggestion an official entered the room and whispered a few words in the detective's ear.
"Show him in at once," said Rathbury. He turned to Spargo as the man quitted the room and smiled significantly. "Here's somebody wants to tell something about the Marbury case," he remarked. "Let's hope it'll be news worth hearing."
Spargo smiled in his queer fashion.
"It strikes me that you've only got to interest an inquisitive public in order to get news," he said. "The principal thing is to investigate it when you've got it. Who's this, now?"
The official had returned with a dapper-looking gentleman in a frock-coat and silk hat, bearing upon him the unmistakable stamp of the city man, who inspected Rathbury with deliberation and Spargo with a glance, and being seated turned to the detective as undoubtedly the person he desired to converse with.
"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."
"Ah!" said Rathbury, winking at Spargo. "So he would, no doubt. And Marbury himself, sir, now? How did he strike you?"
Mr. Myerst gravely considered this question.
"Mr. Marbury struck me," he answered at last, "as a man who had probably seen strange places. And before leaving he made, what I will term, a remarkable remark. About—in fact, about his leather box."
"His leather box?" said Rathbury. "And what was it, sir?"
"This," replied the secretary. "'That box,' he said, 'is safe now. But it's been safer. It's been buried—and deep-down, too—for many and many a year!'"
CHAPTER NINE
"Buried—and deep-down, too—for many and many a year," repeated Mr. Myerst, eyeing his companions with keen glances. "I consider that, gentlemen, a very remarkable remark—very remarkable!"
Rathbury stuck his thumbs in the armholes of his waistcoat again and began swaying backwards and forwards in his chair. He looked at Spargo. And with his knowledge of men, he knew that all Spargo's journalistic instincts had been aroused, and that he was keen as mustard to be off on a new scent.
"Remarkable—remarkable, Mr. Myerst!" he assented. "What do you say, Mr. Spargo?"
Spargo turned slowly, and for the first time since Myerst had entered made a careful inspection of him. The inspection lasted several seconds; then Spargo spoke.
"And what did you say to that?" he asked quietly.
Myerst looked from his questioner to Rathbury. And Rathbury thought it time to enlighten the caller.
"I may as well tell you, Mr. Myerst," he said smilingly, "that this is Mr. Spargo, of the Watchman. Mr. Spargo wrote the article about the Marbury case of which you spoke when you came in. Mr. Spargo, you'll gather, is deeply interested in this matter—and he and I, in our different capacities, are working together. So—you understand?" Myerst regarded Spargo in a new light. And while he was so looking at him. Spargo repeated the question he had just put.
"I said—What did you say to that?"
Myerst hesitated.
"Well—er—I don't think I said anything," he replied. "Nothing that one might call material, you know."
"Didn't ask him what he meant?" suggested
