The unnamed narrator of “The Tell-Tale Heart” by Edgar Allan Poe almost immediately reveals himself to be unreliable and untrustworthy, in terms of his ability to present events as they actually are. The narrator claims he killed an old man because of the man’s evil eye. But his description of the eye suggests that he believes that the eye almost has disembodied evil, a life of its own beyond that of the old man himself. “He had the eye of a vulture --a pale blue eye, with a film over it. Whenever it fell upon me, my blood ran cold; and so by degrees --very gradually --I made up my mind to take the life of the old man, and thus rid myself of the eye forever” (Poe).

Again, he seems to harbor the delusion that it is the old man’s eye, not the old man himself that is generating his sense of unease. “And this I did for seven long nights --every night just at midnight --but I found the eye always closed; and…
