"That he and not Howard was the man in a linen duster, and that he and not Howard was in possession of the keys that night. As these are serious statements to make, I will give you my reasons for them. They are distinct from the recognition of his person by the inmates of the Hotel D----, and added to that recognition, form a strong case against him. The janitor who has charge of the offices in Duane Street, happening to have a leisure moment on the morning of the day on which Mrs. Van Burnam was murdered, was making the most of it by watching the unloading of a huge boiler some four doors below the Van Burnam warehouse. He was consequently looking intently in that direction when Howard passed him, coming from the interview with his brother in which he had been given the keys. Mr. Van Burnam was walking briskly, but finding the sidewalk blocked by the boiler to which I have alluded, paused for a moment to let it pass, and being greatly heated, took out his handkerchief to wipe his forehead. This done, he moved on, just as a man dressed in a long duster came up behind him, stopping where he stopped and picking up from the ground something which the first gentleman had evidently dropped. This last man's figure looked more or less familiar to the janitor, so did the duster, and later he discovered that the latter was the one which he had seen hanging for so long a time in the little disused closet under the warehouse stairs. Its wearer was Franklin Van Burnam, who, as I took pains to learn, had left the office immediately in the wake of his brother, and the object he picked up was the bunch of keys which the latter had inadvertently dropped. He may have thought he lost them later, but it was then and there they slipped from his pocket. I will here add that the duster found by the hackman in his coach has been identified as the one missing from the closet just mentioned. "Third: "The keys with which Mr. Van Burnam's house was unlocked were found hanging in their usual place by noon of the next day. They could not have been taken there by Howard, for he was not seen at the office after the murder. By whom then were they returned, if not by Franklin? "Fourth: "The letter, for the possession of which I believe this crime to have been perpetrated, was found by us in a supposedly secret drawer of this gentleman's desk. It was much crumpled, and bore evidences of having been rather rudely dealt with since it was last seen in Mrs. Van Burnam's hand in that very office.
