"The Tell-Tale Heart" is a short story by American writer Edgar Allan Poe, first published in 1843.
 It is told by an unnamed narrator who endeavors to convince the reader of his sanity, while describing a murder he committed.
 The victim was an old man with a filmy "vulture-eye", as the narrator calls it.
 The murder is carefully calculated, and the murderer hides the body by dismembering it and hiding it under the floorboards.
 Ultimately, the narrator's feelings of guilt, or a mental disturbance, result in him hearing the dead man's beating heart.
