"White's closest associates were Van Bult, Littell, and Davis, and they had all been with him the night of his death. I therefore immediately put detectives on each of them and began my work on the case of Van Bult. I went to his rooms and interviewed his servant. Van Bult left his rooms about seven o'clock on the evening of the murder. His servant, who slept elsewhere, did not see him again till the following morning about half-past six, when he went again to the rooms and found Van Bult there and assisted him in his preparations for a journey, served his breakfast, and saw him off by the eight o'clock train from the New York Central Depot for Buffalo. He had been told by Van Bult the evening before of his intended trip to Buffalo, and had come early that morning by his order. He had not seen Van Bult again till the next succeeding evening, when he had met him at the depot, in obedience to a telegram sent from Buffalo in the name of Van Bult.

"Van Bult's actions on the night of the murder still remained to be accounted for, and I sought information of them elsewhere. The rooms adjoining Van Bult's are occupied by a gentleman named Dean, who is a friend of his. I interviewed Dean. He recalled the night of the murder and stated that on that night Van Bult had returned to his rooms about one o'clock. He recalled the hour because he had been up and Van Bult had come to his room and they had remained together talking for nearly an hour and afterwards he had heard Van Bult for some time moving about in his own rooms.

"In the meanwhile I had sent a man to Buffalo to trace his actions while there. He reported that Van Bult had arrived there on the afternoon after the murder, stopped at the Wilson House till the following morning, and had then taken a train for New York. While in Buffalo he remained most of the time in the hotel, but made a visit to a private insane asylum, of which his wife had for two years been an inmate.

"Van Bult's actions were thus accounted for fully and I was satisfied of his innocence.

"Next I took up the case of Littell. He parted from Mr. Dallas a little before one o'clock on the night of the murder in Madison Square and apparently continued up Fifth Avenue. He testified at the Coroner's inquest that he walked directly to his hotel, The Terrace, near the Park entrance. It was first important that I should determine about this fact. For that purpose I went to the hotel and interviewed the desk clerks. There are two of them who divide the night work, one relieving the other at 1.30 A.M. Littell, on that night, had not reached the hotel during the hours of the first clerk; he did come in about fifteen or twenty minutes after the second one had taken the desk; therefore he arrived about ten or fifteen minutes before two o'clock. There was no trouble in fixing the occasion with the witnesses I interviewed. Littell's association with so sensational a case had made all his actions of that night a matter to be remembered by those who had seen him. I had thus established the fact that nearly an hour had elapsed between the time Littell left Mr. Dallas and that at which he arrived at his hotel. It was altogether improbable under these circumstances that he had gone directly home as he said he had done, but this was still unimportant unless I could track him to the neighborhood of White's house. It was evident that I could not expect to actually locate him there, but I had another means available of establishing his probable presence on the scene if such were a fact. The hour that intervened between his parting with Mr. Dallas and his arrival at the hotel was too much time to have been consumed in a direct walk there, but it was insufficient to admit of his returning to White's house unless he later used some quicker means of reaching the hotel than by walking. In such event he must either have taken the elevated road or a cab. The former seemed the more probable and the easier to determine, so I tried it. I found that at about half-past one o'clock on the night of the murder, a man wearing a long light coat and a soft gray hat, such as Littell had on, took a north-bound train at the Eighteenth Street station. This I learned from the night-guard, whose attention had been especially directed to the passenger because of the necessity of changing a five-dollar bill to make the fare. By itself this was not sufficient to establish the identification but I had a further means at hand. If that man was Littell he must have gotten off at some station near his hotel. At the Fifty-eighth Street station on the same night about ten minutes later Littell got off a north-bound train. The night-guard at this station knew him and spoke to him, for he had been using the station almost daily for several years. I had thus located him at four points within an hour, that is Madison Square, a little before one o'clock; Eighteenth Street elevated station about half after one; Fifty-eighth Street, about ten minutes later, and at the hotel about a quarter before two. I then accounted for his movements in the following way: he had consumed about half an hour from the time he left Madison Square till the time he took the train at Eighteenth Street. Of this period, he was about five minutes returning to White's house; he was there about ten minutes; the remaining fifteen minutes were divided between a journey to Belle Stanton's and thence to the station.

"This all required action, but Littell is a man of quick action. Note that I allowed time for him to have gone to Stanton's. I did this because I have always believed that it was the murderer who left the ulster there.

"The man the night-officer saw leave White's house about a quarter after one o'clock was not White as he supposed, but the murderer wearing his ulster and cap as a disguise. Note again the hour, a quarter past one o'clock; the same at which my calculations place Littell there. There remained another point to be determined.

"If my theory was correct and Littell the man who left White's house, disguised in the ulster, and if he disposed of it at Stanton's house, some explanation had to be found of his means of access to the house. If he had such access it was most likely he secured it through Stanton, with whom he was acquainted.

"From her I learned that Littell probably possessed a key to the front door of the house where she lived; she told me that shortly before the murder Littell had taken her home from a supper somewhere and that she had given him her key to let her in and that he had failed to return it to her. With this key in his possession his means of access to the house is explained. With these facts brought out I had accomplished all I could expect to from the events of that night.

"I could not actually fix the crime on any one because no one saw it committed,—but I had demonstrated:
