June 25, 1890: James McCarthy was brought before the Magistrates. [BOSC]
My father was absent from home at the time of my arrival, and I was informed by the maid that he had driven over to Ross with John Cobb, the groom. Shortly after my return I heard the wheels of his trap in the yard, and, looking out of my window, I saw him get out and walk rapidly out of the yard, though I was not aware in which direction he was going. I then took my gun, and strolled out in the direction of the Boscombe Pool, with the intention of visiting the rabbit warren which is upon the other side. On my way I saw William Crowder, the gamekeeper, as he has stated in his evidence; but he is mistaken in thinking that I was following my father. I had no idea that he was in front of me. When about a hundred yards from the Pool I heard a cry of `Cooee!’ which was a usual signal between my father and myself. I then hurried forward, and found him standing by the Pool. He appeared to be much surprised at seeing me, and asked me rather roughly what I was doing there. A conversation ensued, which led to high words, and almost to blows, for my father was a man of a very violent temper. Seeing that his passion was becoming ungovernable, I left him, and returned towards Hatherley Farm. I had not gone more than one hundred and fifty yards, however, when I heard a hideous outcry behind me, which caused me to run back again. I found my father expiring on the ground, with his head terribly injured. I dropped my gun, and held him in my arms, but he almost instantly expired.
June 25, 1889: Holmes investigated Colonel Barclay’s death. [CROO]
That was the state of things, Watson, when upon the Tuesday morning I, at the request of Major Murphy, went down to Aldershot to supplement the efforts of the police. I think you will acknowledge that the problem was already one of interest, but my observations soon made me realize that it was in truth much more extraordinary than would at first sight appear.
