Who wrote the Gothic short story 'The Tell-Tale Heart'?

Edgar Allan Poe wrote the Gothic short story 'The Tell-Tale Heart'.

First published in 1843, the story is told by an unnamed narrator who insists on being sane while describing the calculated murder of an old man. The narrator claims not to hate the victim, but becomes fixated on his “vulture” eye. After killing him, the narrator hides the dismembered body beneath the floorboards and confidently receives several police officers.

The story's famous psychological turn comes when the narrator hears what seems to be the dead man's heartbeat growing louder beneath the floor. The officers do not appear to hear it, so the sound may be a hallucination produced by guilt and panic. Unable to endure the imagined evidence, the narrator confesses and tells the officers to tear up the boards.

Poe leaves many details deliberately unclear, including the narrator's gender, relationship to the old man, and exact motive. That uncertainty intensifies the story's unease. The tale is a classic of Gothic fiction because it combines claustrophobic setting, murder, unreliable narration, obsession, and the collapse of a mind that tries—and fails—to prove its own rationality.
