"That night I dreamt of obscene things. I awoke with their images hovering by my bedside, looking at me with sneering eyes, mocking me with lewd gestures. 'Your honour and the honour of the Herediths--Where is it?' they kept repeating: 'Sold by the wanton you have made your wife. What is honour to the lust of the flesh? There is nothing so strong in the world.' But as I watched them the ceiling rolled away, and in the darkness of the sky a stern and implacable face appeared. And it said, 'There is one thing stronger than honour, stronger even that the lust of the flesh, and that is--Death.' "It was the answer to a question I had been asking myself ever since I knew. I got up, and sat by the open window, to plan how I should kill them both. But I wanted the man to feel more than a swift thunderstroke of mortal agony. I wished to make him suffer as I had suffered, but at first I could see no way. "Then it came to me in the strangest way--a light, a direction, a guide. I had been smoking as I sat there thinking--smoking cigarettes which I lit with a little automatic lighter I always used. I must have laid it down carelessly, for I was interrupted in my meditations by the sight of a thin trail of vapour ascending from the window ledge. I had failed to put the extinguisher on the lighter, and the wick had gone on burning. As I watched the red spark crawling almost imperceptibly along the yellow wick, there dawned in my mind the first glimmering of the idea of a slow match and a delayed report. Bit by bit it took form, and the means of my revenge was made clear to me. I went back to bed and slept soundly. "I was in no hurry to act. There was much to think over, much to do, before the plan was finally perfected. I carried out experiments in the gun-room when everybody was in bed, secure in the knowledge that no report, however loud, could penetrate from those thick walls upstairs. While I was making ready I watched them both. Not a furtive glance or caress passed between them which I did not see. "The night my aunt asked Violet about the necklace I suspected that it was no longer in her possession. I guessed that by her evasive answers and telltale face. When she left the room and went upstairs I crept after her in the shadows and followed her to the door of Nepcote's room. I listened to their conversation; I heard him promise her to return secretly to the moat-house on the following night with the necklace. My heart leapt as I listened. I believed that I had him.
