Read the excerpt from "the tell-tale heart.”

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.

read the excerpt from "the black cat.”

for the most wild, yet most homely narrative which i am about to pen, i neither expect nor solicit belief. mad indeed would i be to expect it, in a case where my very senses reject their own evidence. yet, mad am i not—and very surely do i not dream. but to-morrow i die, and to-day i would unburthen my soul.
