The Tell-tale Heart

Introduction
One of Edgar Allen Poe's most famous works, this story was first published in 1843. In this story, the narrator has to take care of an old man with a vulture's eye. In a fit of rage, he murders the man and hides his body under the floorboards. When the police arrive to search for the body, he hears a heartbeat that grows louder and louder until he goes insane and gives himself up.

Effects
If one carries the book on their person, then the user will get angry at someone for a perceived slight, murder them in cold blood, and hide their bodies under the floor. The book then lets out a heartbeat that makes the user hallucinate flashbacks of their misdeeds and grows louder and louder until they go insane and confess their deed. Some health-based artifacts can be used to cure the user's insanity, and the book is stored in the Dark Vault for this reason.
