It will be remembered that in my first despatch I described the situation as I found it on reaching this place early on Tuesday morning. I told how the body was found, and in what state; dwelt upon the complete mystery surrounding the crime and mentioned one or two local theories about it; gave some account of the dead man's domestic surroundings; and furnished a somewhat detailed description of his movements on the evening before his death. I gave, too, a little fact which may or may not have seemed irrelevant: that a quantity of whisky much larger than Manderson habitually drank at night had disappeared from his private decanter since the last time he was seen alive. On the following day, the day of the inquest, I wired little more than an abstract of the proceedings in the coroner's court, of which a verbatim report was made at my request by other representatives of the _Record_; and it will be remembered that the police evidence showed that two revolvers, with either of which the crime might have been committed, had been found--one in Manderson's bureau and the other in the room of the secretary, Marlowe; but that no importance could be attached to this, as the weapons were of an extremely popular make. I write these lines in the last hours of the same day; and I have now completed an investigation which has led me directly to the man who must be called upon to clear himself of the guilt of the death of Manderson. Apart from the central mystery of Manderson's having arisen long before his usual hour to go out and meet his death, there were two minor points of oddity about this affair which, I suppose, must have occurred to thousands of those who have read the accounts in the newspapers; points apparent from the very beginning. The first of these was that, whereas the body was found at a spot not thirty yards from the house, all the people of the house declared that they had heard no cry or other noise in the night. Manderson had not been gagged; the marks on his wrists pointed to a struggle with his assailant; and there had been at least one pistol-shot. (I say at least one, because it is the fact that in murders with firearms, especially if there has been a struggle, the criminal commonly misses his victim at least once.) This odd fact seemed all the more odd to me when I learned that Martin, the butler, was a bad sleeper, very keen of hearing, and that his bedroom, with the window open, faced almost directly toward the shed by which the body was found.
