The Narrator starts off with saying he is not mad nor crazy. He is simply just nervous, diseased, and has obviously signaling internal conflict. He claims he can tell us everything calmly. The Narrator says he wanted to kill an old man, only because his "vulture" like eyeball.
The Narrator is kind to the old man for a week, although the sight of the eye disturbed him. Every night at 12 A.M. he would watch the old man sleep. He would open the lantern, attempting to check if the Old Man's eye was open. In the morning, he would ask how he slept each morning. The Narrator at this point is confirmed to be the antagonist of this story.
The Narrator, on the 8th night, tries to open the lantern again, but in the process his finger slips and it makes a noise. They both have a one hour stand off. The Narrator once again tries to open the lantern, he saw the Old Mans eye. Suddenly, the Narrator hears a low, dull, quick sound. The quick sound is in fact his heart beat, this symbolizes his severe anxiety, caused by all the suspense.
At the dead hour of night, which is foreshadowing, a new anxiety overtakes the Narrator, he is scared that the neighbors will here the heart beat as the volume increasing. Death stalked the old man (personification). Finally, he lets out a shriek and suffocated the with a mattress.
After the old man is killed by the Narrator, he was dismembered in the bathtub. The Narrator, claiming to be very cautious for doing so, hid the body under the floorboards. Later, the police knock on his door, suspicious due to the neighbors calling because of a shriek late at night. The Narrator, being overly confident, willingly invites the police in, when he sits down, right over the floorboards in which he hid the body, he began to hear another intense heart beat.
At this point, the Narrator is overwhelmingly anxious. The anxiety overtakes him, and he screams at the officers, admitting the deed and telling them the location of the dead body.
