"So you see he would have been a very profound old man, indeed, to suspect that every night, just at twelve, I looked upon him while he slept."
"It was open-wide, wide open-and I grew furious as I gazed upon it... I knew that sound well, too. It was the beating of the old man's heart."
"In an instant I dragged him to the floor, and pulled the heavy bed over him."
The narrator, for seven nights, watches upon the Old Man and his eye while he sleeps, becoming, more anxious and angry.
"First of all I dismembered the corpse. I cut off the head and the arms and the legs."
On the eighth night, the narrator walks into the old man's room and sees his eye open in the ray of light while hearing the beating noise of his heart.
"The shriek, I said, was my own dream. The old man was absent in the country."
After carefully watching the Old Man, the narrator crept into the room, awoke the Old Man, and killed him quickly.
I admit the deed!--tear up the planks!--here,here!--it is the beating of his hideous heart!
Before anyone could notice, the narrator disposed of the body by putting the body and limbs in a secret location.
Just after the narrator hid the evidence, police officers came knocking at the door and he explained to them that everything was fine.
Towards the end of the narrator's conversation with the police officer's, he began to hear the heartbeat again. It grew so loud that he went back to the Old Man and ripped out his heart for the police officers. Finally, the narrator admitted to killing the Old Man.
