Seeing your imminent peril, I also fired--and he fell. I saved you, but I killed the man whom I was compelled to call father, though I had good reasons to hate his memory. He killed my poor mother by sheer brutality and neglect, and made me his puppet and decoy in his nefarious schemes. When he fell, you rushed from the spot, believing that you had killed him, but if you will refer to the medical evidence you will find that he was struck by a single bullet beneath the left shoulder-blade. That shot was the one I fired, and could not possibly have been fired by you. In order to tell you the truth, and yet not commit myself, I sent you anonymously, a few weeks after the occurrence, a piece of tracing-paper with a diagram upon it, and a few words, which were purposely rather vague, hoping that the plan of the spot would show you that you were innocent, and that in case you were afterwards charged with the crime you would be able to use the plan in your defence. Confession I make calmly and of my own free will, in order that it may be signed by the woman who is my companion and my most intimate friend, and that it may be opened by your own hand when I am dead and beyond the reach of man's justice." There was nothing else. Only the signature, "May Beatrice Brodie," together with that of Muriel Mortimer. "This clearly explains how the woman Mortimer, or Biancheri, obtained possession of your secret," observed Cator in surprise, after he had read it through aloud. "My inquiries, I recollect, showed that she entered Mrs. Brodie's employ as companion and was in India for six months, but that she returned, owing to the climate, and again took up her abode with the Meldrums. The explanation given by the Meldrums to friends was that she had been out to India on a visit. Having obtained knowledge of your secret, she imparted it to Biancheri after her marriage, with the result that he and his associates made the clever attempt to blackmail you. She, no doubt, felt herself safe as long as her late employer was living, and is, of course, in ignorance of her death and the passing of this confession into your hands." ------------------------------------------------------------------------
