The Haunted Man and the Ghost's Bargain

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'.
