When the police arrive, called by neighbors who heard a scream, the narrator appears calm and confident. However, while speaking to the officers, he begins to hear the sound of a beating heart, growing louder and louder. Consumed by guilt and madness, he breaks down and confesses the crime.

The story is short but intense, marked by repetition and rising rhythm that mirror the narrator’s mental state. Its unreliable narrator, dark tone, and psychological focus make it a classic example of the short story genre, highlighting themes of guilt, obsession, and madness.
