"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".
"I knew what the old man felt, and pitied him although i chuckled at heart".
"There was no pulsation. He was stone dead. His eye would trouble me no more."
The narrator is trying to tell the readers that he is sane and not mad. The narrator has a plan to kill the old man cause he hates his blind eye.
*Knock Knock Knock*
The narrator sneaks into the old mans room for eight nights to see if his eye is open. On the eight night the narrator killed the man and strangled him with a mattress.
The narrator killed the man and cut up his body and hid the pieces of his body under the floorboards.
"I admit the deed! tear up the planks!- here, here!- it is the beating of his hideous heart."
The narrator heard a knock at the door and franticly opened the door realizing it was the police.
The narrator remained calm and took the police officers around the house and into the room where he killed the old man and placed the chair he is sitting in right over his body.
The narrator heard his heart beating louder and louder and thought the police suspected something even though they had no idea. The narrator owned up to what he did and showed the police where he hid the body.
