Just as I was turning away wearily from the window to go back to the bedroom and make a second attempt to complete the unfinished entry in my journal, I smelt the odour of tobacco-smoke stealing towards me on the heavy night air. The next moment I saw a tiny red spark advancing from the farther end of the house in the pitch darkness. I heard no footsteps, and I could see nothing but the spark. It travelled along in the night, passed the window at which I was standing, and stopped opposite my bedroom window, inside which I had left the light burning on the dressing-table.
