The narrator was haunted by the old man's vulture eye. And he wants to kill him. Each night, he spys on him while he's asleep. The narrator is very boastful in what is he doing.
Each night for eight nights, the narrator peers into the old man's room waiting for him to wake up.
While the narrator was trying to open the lantern he accidentally dropped it and woke up the old man. And he stood up in great terror when he felt the presence of someone else in the room.
On the eighth night, after the narrator dropped the lantern. He starts to hear the old man's heart beat faster and faster. And he is afraid that the neighbors will hear the sound of his heart, so with a loud yell the narrator suffocates him by turning his bed over on him. And he kills him!!
After he killed him, he made sure the reader knew that he wasn't mad-he just did what was just! Once the police came to the narrator's door because someone heard a shriek. He confidently gave them a tour around the whole house. When he invited them to sit and rest, the narrator placed a chair on top of the spot where he hid the old man's dead body.
While sitting over the old man's body, the narrator heard a sound, almost exactly like a beating heart. And he slowly grew nervous and pale. As soon as he couldn't take it anymore, he confessed that he...KILLED THE OLD MAN!!
