"I stole away quietly without waiting to learn any more, but I stayed up till far into the night preparing my final plans. My intention was to shoot her just before dinner, and arrange for the false report to explode after he had arrived and hidden himself in the old staircase, waiting for her to go to him. Then, when the report startled everybody in the dining-room, I intended to be the first to rush upstairs, and lead the search in the direction of the old staircase. I would have had him by the throat, before he had time to get away. How would he have been able to account for his secret presence in the house when her jewels were in his pocket and her dead body upstairs, close to where he was hiding? "I had intended to kill Violet with a small revolver which I had bought in a second-hand place at London last winter, but Nepcote's carelessness in leaving his own revolver in the gun-room gave the last finishing touch to my plan. I could scarcely believe my luck when I found it. It seemed as though he himself were playing into my hands. I hid it away, expecting that there would be inquiries, but there were none. He had forgotten all about it. It was strange, too, that Violet herself helped by telling my aunt before dinner on the night of her pretended illness that she did not wish to be disturbed by anybody. That removed a defect in my arrangements which had caused me much anxious thought. I had feared that somebody, probably a servant, might enter the room in the period between the first and second reports. It was a chance I could not afford to overlook, and I could see no way of guarding against it except by locking the door, which I did not want to do. I wanted to leave the door partly open so as to make sure of the second report penetrating to the dining-room downstairs. "When my aunt gave me Violet's message in the library shortly before dinner I knew that the moment had arrived. The altered arrangements for an earlier dinner cost me a moment's perplexity, but no more. One cannot hurry one's own guests, and I knew it would be impossible to get dinner over as quickly as my aunt anticipated. If it were ending too quickly for my purpose it would be an easy matter to introduce a subject which would set somebody talking. That, as you know, is what actually happened.
