One night, about the close of my fifth year at the school, and immediately after the altercation just mentioned, finding every one wrapped in sleep, I arose from bed, and, lamp in hand, stole through a wilderness of narrow passages from my own bedroom to that of my rival. I had long been plotting one of those ill-natured pieces of practical wit at his expense in which I had hitherto been so uniformly unsuccessful. It was my intention, now, to put my scheme in operation, and I resolved to make him feel the whole extent of the malice with which I was imbued. Having reached his closet, I noiselessly entered, leaving the lamp, with a shade over it, on the outside. I advanced a step, and listened to the sound of his tranquil breathing. Assured of his being asleep, I returned, took the light, and with it again approached the bed. Close curtains were around it, which, in the prosecution of my plan, I slowly and quietly withdrew, when the bright rays fell vividly upon the sleeper, and my eyes, at the same moment, upon his countenance. I looked;—and a numbness, an iciness of feeling instantly pervaded my frame. My breast heaved, my knees tottered, my whole spirit became possessed with an objectless yet intolerable horror. Gasping for breath, I lowered the lamp in still nearer proximity to the face. Were these—these the lineaments of William Wilson? I saw, indeed, that they were his, but I shook as if with a fit of the ague in fancying they were not. What was there about them to confound me in this manner? I gazed;—while my brain reeled with a multitude of incoherent thoughts. Not thus he appeared—assuredly not thus—in the vivacity of his waking hours. The same name! the same contour of person! the same day of arrival at the academy! And then his dogged and meaningless imitation of my gait, my voice, my habits, and my manner! Was it, in truth, within the bounds of human possibility, that what I now saw was the result, merely, of the habitual practice of this sarcastic imitation? Awe-stricken, and with a creeping shudder, I extinguished the lamp, passed silently from the chamber, and left, at once, the halls of that old academy, never to enter them again.
