In “The Haunted Man and the Ghost’s Bargain”, Professor Redlaw nurses grievances and past wrongs done to him as he stares into the fire. Visited by a spirit who appears to him as his phantom twin, he is offered a way to “forget the sorrow, wrong, and trouble” he has known. This intervention has consequences for the people in Redlaw’s life, and leads to a resolution of his troubles. This is the last of the five Dickens Christmas Books that begin with “A Christmas Carol”.
