The Tell-Tale Heart
In the "Tell-Tale Heart", Edgar Allen Poe examines themes of sanity vs. madness

We see this nervousness again on the eighth night as he is staring at the "vulture eye".

He says "I have told you that I am nervous: so I am"(Poe 356). In his nervousness, the sound of the beating heart "incited me to uncontrollable terror". (Poe 356) His nervousness that a neighbor may hear the sound urges him to kill the man. The fact that he attributes his own fear and nervousness to the old man once again...
