I. The Pale Blue Eye

True! — nervous — very, very dreadfully nervous I had been and am; but why will you say that I am mad? The disease had sharpened my senses — not destroyed — not dulled them.

Above all was the sense of hearing acute. I heard all things in the heaven and in the earth. I heard many things in hell. How, then, am I mad? Hearken! and observe how healthily — how calmly I can tell you the whole story.

Object there was none. Passion there was none. I loved the old man. He had never wronged me. He had never given me insult. For his gold I had no desire.

I think it was his eye! yes, it was this! 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.
