After his disappointment at discovering that the button which he had found was less valuable than he had at first supposed, he had decided upon a mode of procedure from which he hoped to gain much. He had seen many men flinch when brought unexpectedly into the presence of their murdered victim. He knew that many in a fit of passion, or even in cold blood, might have the nerve to take human life. Few resisted a shudder when shown the ghastly, mutilated, perhaps decomposing corpse. When he left the hotel that morning it was about ten o'clock. Whilst he had been convinced by Mr. Mitchel that the button found at the scene of the murder was not one of the original set, or rather that it could not be proven that it had been, he was equally satisfied, that the fact that it presented a portrait of Miss Remsen was significant. Thus, after all, it was possible that Mr. Mitchel had murdered the woman, or at least he had visited the apartment. In either case, supposing that he knew the woman was dead, it would be idle to take him up three flights of stairs to confront him with the body, for that would give him ample premonition of what was about to occur, and he would readily control his countenance. This is what the detective did: He went at once to the coroner, and told him enough to have him render his assistance. Therefore during the time which had elapsed, the coroner had impanelled a jury, taken them to the scene of the crime, and then adjourned the inquest, leaving the doctors to perform the autopsy. The body had been taken down to a room on the first floor which opened directly on the main hall. Here it was laid out upon a table, so placed that the gaping wound and now hideous face would at once meet the gaze of any one entering. The doctors had been instructed to postpone their work until the arrival of the detective. Thus Mr. Barnes knew, as he led the way down stairs, that his trap was set. As they reached the main hall, he spoke: "Gentlemen, I am about to ask a favor of you. You were both on the train when the robbery was committed. There is a question in relation to it which I should like to ask both of you, and hear each answer separately. Would you oblige me?" "With pleasure," said the Frenchman. "I have already told you that you may ask me any questions," said Mr. Mitchel. "Thank you." Turning to the hall-boy, who of course had been taught his part, he continued: "Can we find a room where we can talk privately for a few minutes?" "Yes sir; step this way," and the boy led them towards the one where the corpse lay.
