The narrator dismembers the body and hides the pieces below the floorboards in the bedroom. He is careful not to leave even a drop of blood on the floor. As he finishes his job, a clock strikes the hour of four. At the same time, the narrator hears a knock at the street door. The police have arrived, having been called by a neighbor who heard the old man shriek. The narrator is careful to be chatty and to appear normal. He leads the officers all over the house without acting suspiciously. At the height of his bravado, he even brings them into the old man’s bedroom to sit down and talk at the scene of the crime. The policemen do not suspect a thing. The narrator is comfortable until he starts to hear a low thumping sound. He recognizes the low sound as the heart of the old man, pounding away beneath the floorboards. He panics, believing that the policemen must also hear the sound and know his guilt. Driven mad by the idea that they are mocking his agony with their pleasant chatter, he confesses to the crime and shrieks at the men to rip up the floorboards.
