Up to this time I had always considered myself fairly brave, but I now began to question my right to the title. Should I return whence I came, safe in limb, sane in mind, but baffled in my quest by my own fears, or should I invite one of the servants to accompany me? No! I determined to venture by myself. What a fine thing it would be, if, alone and unaided, I should succeed in solving the mystery that gave this chamber the reputation of being haunted! I should be the hero of the hour, eclipsing all the male guests of Silverdale and receiving the smiles and praises of the women. While the men were singing carols at a safe distance, I should have been keeping a solitary vigil in a moonlit hall surrounded by ghostly perils. Vanity rather than courage inspired me to proceed. I could still hear the carolling of the servants, and the sound, remote though it was, gave me a sense of safety. Once more I turned the key, and then flung wide the door. Before entering, I gazed down the gallery, but no sound came from it now, and nothing moving was to be seen. It was a superb night. The moon was at the full, and its bright rays, falling upon the tall casements, flung parallelograms of light across the polished oak flooring, causing the gallery to present a chequered appearance, silver alternating with ebony in regular perspective. A more weird place to spend a night in could hardly be imagined, and I quite forgave the servants for believing it to be haunted. Mailed warriors and mounted knights shimmered in the moonlight apparently on the point of starting into life and action; the eyes of the portraits on the walls seemed to stare at me with a marvellous resemblance to those of human beings; mysterious shapes seemed to be lurking in the alcoves, whispering and pointing at me as I advanced with beating heart. I had not taken more than ten steps when the great door swung to on its hinges with a clang that gave me a sudden start and called forth strange echoes from the gallery. There is nothing remarkable in the clanging of a door, if it be due merely to a current of air or to automatic action; but when neither of these causes is in operation it is apt to create an uneasy sensation, especially when, as in the present instance, it is accompanied by what sounds very like a laugh, coming it is impossible to say whence. I felt afraid almost to turn round to discover the author of the laugh, but when I had turned and could perceive nothing to justify my belief that it was a laugh, I was equally afraid to turn the other way, and so stood rooted to the spot for a few moments, not wishing to retire, nor yet overbold to go forward.
