The Haunted Man and the Ghost’s Bargain - a novella by Charles Dickens, an English writer who is regarded by many as the greatest novelist of the Victorian era.

Redlaw is a teacher of chemistry who often broods over wrongs done him and grief from his past. He is haunted by a spirit, who is not so much a ghost as Redlaw's phantom twin and is "an awful likeness of himself...with his features, and his bright eyes, and his grizzled hair, and dressed in the gloomy shadow of his dress..." This spectre appears and proposes to Redlaw that he can allow him to "forget the sorrow, wrong, and trouble you have known...to cancel their remembrance..." Redlaw is hesitant at first, but finally agrees.
