A faded moonbeam fell on the floor, and filled the place with an ancient dream-light, which wrought strangely on my brain, and filled it, as if it, too, were but a deserted, sleepy house, haunted by old dreams and memories. Recollecting myself, I went back for a light; but the candles were both flickering in the sockets, and I was compelled to trust to the moon. I ascended the staircase. Old as it was, not a board creaked, not a banister shook--the whole felt solid as rock. Finding, at length, no more stair to ascend, I groped my way on; for here there was no direct light from the moon--only the light of the moonlit air. I was in some trepidation, I confess; for how should I find my way back? But the worst result likely to ensue was, that I should have to spend the night without knowing where; for with the first glimmer of morning, I should be able to return to my room. At length, after wandering into several rooms and out again, my hand fell on a latched door. I opened it, and entered a long corridor, with many windows on one side. Broad strips of moonlight lay slantingly across the narrow floor, divided by regular intervals of shade. I started, and my heart swelled; for I saw a movement somewhere--I could neither tell where, nor of what: I was only aware of motion. I stood in the first shadow, and gazed, but saw nothing. I sped across the light to the next shadow, and stood again, looking with fearful fixedness of gaze towards the far end of the corridor. Suddenly a white form glimmered and vanished. I crossed to the next shadow. Again a glimmer and vanishing, but nearer. Nerving myself to the utmost, I ceased the stealthiness of my movements, and went forward, slowly and steadily. A tall form, apparently of a woman, dressed in a long white robe, appeared in one of the streams of light, threw its arms over its head, gave a wild cry--which, notwithstanding its wildness and force, had a muffled sound, as if many folds, either of matter or of space, intervened--and fell at full length along the moonlight. Amidst the thrill of agony which shook me at the cry, I rushed forward, and, kneeling beside the prostrate figure, discovered that, unearthly as was the scream which had preceded her fall, it was the Lady Alice. I saw the fact in a moment: the Lady Alice was a somnambulist. Startled by the noise of my advance, she had awaked; and the usual terror and fainting had followed. She was cold and motionless as death. What was to be done? If I called, the probability was that no one would hear me; or if any one should hear--but I need not follow the course of my thought, as I tried in vain to recover the poor girl. Suffice it to say, that both for her sake and my own, I could not face the chance of being found, in the dead of night, by common-minded domestics, in such a situation.
