"I searched the two big rooms--a dining-room and a back sitting-room--on the ground floor, but finding no one, I stood at the bottom of the stairs and shouted, thinking to discover the whereabouts of the invalid who had rung the bell. There was no answer. The place was dark, so I struck a match, ascended to the first floor and entered the front room, which proved to be a good-sized, well-furnished drawing-room, dimly lit by the street-lamp opposite shining through the windows. At the further end, suspended from the ceiling, a curious lamp was burning in red glass, just like those one sees in Roman Catholic churches, and on examining it I found it to be a little float in oil, so arranged that it would burn continuously for many days and nights without attention. It looked strange and weird, a red spot in the darkness at the end of the room; but what was stranger and more amazing was a discovery I made a moment later when, my eyes having grown used to the semi-obscurity of the room, I discerned two human forms, one that of a woman lying back in an armchair as if asleep, and the other a man, who had fallen close by and was lying outstretched upon the carpet. Even the faint light of the match I struck told me that both were dead, and so startled was I by this unexpected revelation that with scarcely a second glance round the weird place I hastened downstairs and left by the front door." "You went on to the station at once, I suppose?" "Yes," he answered; then after a pause he looked straight into my face, adding, "but to tell the truth, Urwin, you and I are the only persons who know of this affair. I haven't reported it." "Haven't reported it?" I echoed. "Why not? Delay may prevent the mystery being unravelled." "I know it's absurd and foolish," he faltered in an unsteady voice, "but the fact is, I entertain a deep-rooted superstition about snakes. My poor wife was always dreaming of snakes before she died, and strangely enough, whenever I have seen those reptiles in my dreams some bad luck, catastrophe or bereavement has always fallen upon me immediately afterwards." "It isn't like you to speak thus, Patterson," I said, knowing him to be a fearless man who more than once had boldly faced a burglar's revolver. "I really don't know what to do," he said. "It's nearly two hours ago since I entered the place. I was so upset when I came out that I went to the telegraph office and wired to you, in the hope that you might be able to suggest some plan of action." "Report at once and let's thoroughly investigate it," I said promptly. "No. I can't report it on account of that snake. If I did, I feel assured that some fatality would fall upon me." "You're unnerved by what you've seen," I said. "It certainly was not a nice position to unexpectedly find oneself alone with the dead in a dark deserted house like that. In any case, however, the matter is a queer one and must be sifted."
