What is revel heart?

As an AI language model, I do not have access to private or personal information about individuals. However, if you are referring to the book "The Tell-Tale Heart" by Edgar Allan Poe, it is a short story that was first published in 1843. The story is told from the perspective of an anonymous narrator who is trying to justify his decision to murder an old man because of his "vulture eye." The narrator subsequently hears the man's heart beat loudly, seeming to reveal his guilt. The story is often cited as an example of Poe's use of psychological horror and suspense in his writing.
