One day, descending into the cellar of the building with his wife, the narrator almost trips over the cat. Enraged, the narrator grabs an axe to attack the cat, but his wife defends the animal. Further angered by this interference, the narrator turns his rage at his wife and buries the axe in her head. Faced with the evidence of his crime, the narrator considers many options for the body’s disposal, including dismemberment and burial. The narrator eventually decides to take advantage of the damp walls in the basement and entomb the body behind their plaster. Without any difficulty, the narrator creates a tomb in the plaster wall, thereby hiding the body and all traces of his murder. When he finally turns to the cat, it is missing, and he concludes that it has been frightened away by his anger. 

On the fourth day after the murder, the police arrive unexpectedly at the narrator’s apartment. Cool and collected, the narrator leads them through the premises, even into the basement. Though facing the scene of the crime, the police do not demonstrate any curiosity and prepare to leave the residence. The narrator, however, keeps trying to allay their suspicion. Commenting upon the solid craftsmanship of the house, he taps on the wall—behind which is his wife’s body—with a cane. In response to the tapping, a long, loud cry emanates from behind the wall. The police storm the wall and dismantle it, discovering the hidden corpse. Upon its head sits the missing cat.
