"TRUE! --nervous --very, very dreadfully nervous I had been and am...How, then, am I mad? Hearken! and observe how healthily --how calmly I can tell you the whole story."
"carefully, I lifted the cloth, just a little, so that a single, thin, small light fell across that eye. For seven nights I did this, seven long nights, every night at midnight. Always the eye was closed..."
The narrator spies on the old man while he is sleeping, but his eye is closed
"The eighth night I was more than usually careful as I opened the door...The old man was lying there not dreaming that I was at his door. Suddenly he moved in his bed... Suddenly the old man sat straight up in bed and cried, “Who’s there??!”
On the eight night, the narrator opens the door and wakes the old man
'Slowly, little by little, I lifted the cloth, until a small, small light escaped from under it to fall upon — to fall upon that vulture eye! It was open — wide, wide open...The time had come! I rushed into the room, crying, “Die! Die!” The old man gave a loud cry of fear as I fell upon him and held the bed covers tightly over his head"
The narrator sees the eye, kills the old man, and buries him under the floorboards.
The police show up, he welcomes them, and shows them around. " I took them through the whole house, telling them to search it all, to search well. I led them finally into the old man’s bedroom. As if playing a game with them I asked them to sit down and talk for a while"
He feels guilty and admits the crime to the police who knew all along
Villains!" I shrieked, "dissemble no more! I admit the deed! --tear up the planks! here, here! --It is the beating of his hideous heart!"
