'The Tell-Tale Heart' is a short story by Edgar Allan Poe first published in 1843. It follows an unnamed narrator who insists on his sanity after murdering an old man with a 'vulture eye'. The murder is carefully calculated, and the murderer hides the body by cutting it into pieces and hiding it under the floorboards. Ultimately the narrator's guilt manifests itself in the hallucination that the man's heart is still beating under the floorboards.
The story was first published in James Russell Lowell's The Pioneer in January 1843. 'The Tell-Tale Heart' is widely considered a classic of the Gothic fiction genre and one of Poe's most famous short stories.
