Now I am rather an imaginative person; that is why engineering captured my fancy. It was through his trying to make an architect (a person who quarrels with women about their kitchen sinks!) of a boy who wanted to be an engineer that my grandfather and I failed to hit it off. From boyhood I have never seen a great bridge or watched a locomotive climb a difficult hillside without a thrill; and a lighthouse still seems to me quite the finest monument a man can build for himself. My grandfather’s devotion to old churches and medieval houses always struck me as trifling and unworthy of a grown man. And fate was busy with my affairs that night, for, instead of lighting my pipe with the little sketch, I was strangely impelled to study it seriously. I drew for myself rough outlines of the interior of Glenarm House as it had appeared to me, and then I tried to reconcile the little sketch with every part of it. “The Door of Bewilderment” was the charm that held me. The phrase was in itself a lure. The man who had built a preposterous house in the woods of Indiana and called it “The House of a Thousand Candles” was quite capable of other whims; and as I bent over this scrap of paper in the candle-lighted library it occurred to me that possibly I had not done justice to my grandfather’s genius. My curiosity was thoroughly aroused as to the hidden corners of the queer old house, round which the wind shrieked tormentingly. I went to my room, put on my corduroy coat for its greater warmth in going through the cold halls, took a candle and went below. One o’clock in the morning is not the most cheering hour for exploring the dark recesses of a strange house, but I had resolved to have a look at the ravine-opening and determine, if possible, whether it bore any relation to “The Door of Bewilderment.” All was quiet in the great cellar; only here and there an area window rattled dolorously. I carried a tape-line with me and made measurements of the length and depth of the corridor and of the chambers that were set off from it. These figures I entered in my note-book for further use, and sat down on an empty nail-keg to reflect. The place was certainly substantial; the candle at my feet burned steadily with no hint of a draft; but I saw no solution of my problem. All the doors along the corridor were open, or yielded readily to my hand. I was losing sleep for nothing; my grandfather’s sketch was meaningless, and I rose and picked up my candle, yawning. Then a curious thing happened. The candle, whose thin flame had risen unwaveringly, sputtered and went out as a sudden gust swept the corridor. I had left nothing open behind me, and the outer doors of the house were always locked and barred. But some one had gained ingress to the cellar by an opening of which I knew nothing.
