"Be that as it may," said Sir Henry, "the diseased brain can give such torture to its victim that death is preferable. All my life I have been what I consider a healthy minded man. I have plenty of money, and have never been troubled with the cares which torture men of commerce, or of small means. When I married, three years ago, I considered myself the most lucky and the happiest of mortals." "Forgive a personal question," I interrupted. "Has your marriage disappointed you?" "No, no; far from it," he replied with fervour. "I love my dear wife better and more deeply even than the day when I took her as a bride to my arms. It is true that I am weighed down with sorrow about her, but that is entirely owing to the state of her health." "It is strange," I said, "that she should be weighed down with sorrow about you for the same cause. Have you told her of the thing which terrifies you?" "Never, never. I have never spoken of it to mortal. It is remarkable that my wife should have told you that I looked like a man who has seen a ghost. Alas! alas! But let me tell you the cause of my shattered nerves, my agony, and failing health." "Pray do, I shall listen attentively," I replied. "Oh, doctor, that I could make you feel the horror of it!" said Sir Henry, bending forward and looking into my eyes. "Three months ago I no more believed in visitations, in apparitions, in so-called ghosts, than you do. Were you tried as I am, your scepticism would receive a severe shock. Now let me tell you what occurs. Night after night Lady Studley and I retire to rest at the same hour. We say good-night, and lay our heads on our separate pillows. The door of communication between us is shut. She has a night-light in her room--I prefer darkness. I close my eyes and prepare for slumber. As a rule I fall asleep. My sleep is of short duration. I awake with beads of perspiration standing on my forehead, with my heart thumping heavily and with every nerve wide awake, and waiting for the horror which will come. Sometimes I wait half an hour--sometimes longer. Then I know by a faint, ticking sound in the darkness that the Thing, for I can clothe it with no name, is about to visit me. In a certain spot of the room, always in the same spot, a bright light suddenly flashes; out of its midst there gleams a preternaturally large eye, which looks fixedly at me with a diabolical expression. As time goes, it does not remain long; but as agony counts, it seems to take years of my life away with it. It fades as suddenly into grey mist and nothingness as it comes, and, wet with perspiration, and struggling to keep back screams of mad terror, I bury my head in the bed-clothes." "But have you never tried to investigate this thing?" I said. "I did at first. The first night I saw it, I rushed out of bed and made for the spot. It disappeared at once. I struck a light--there was nothing whatever in the room." "Why do you sleep in that room?"
