The narrator is thinking about the old mans eye and he wants to kill the old man because he thinks he is evil because he has that kind of eye.
The narrator spied on the old man for seven nights. He did this every night at midnight. He was really careful and quiet. He started to hear the old mans heart.He used a lantern to shine on the eye to see if it was open. The lantern made a noise and it woke the old man. The eye was open.
The narrator now killed the old man by suffocating him.
Now he put the old man in the bath tub to kill him and take out his eye.
The narrator said "I killed the old man." The cops said you are going to jail and he is in jail for life.
