"The Haunted Man and the Ghost's Bargain" is Charles Dickens 19th century novella that concludes his series of five Christmas books written between 1843 and 1848. It is the story of Professor Redlaw, a chemistry teacher who is constantly brooding over the grief caused by past wrongs done to him. Redlaw is haunted by a spirit who takes from him these painful memories, which leaves him unexpectedly bitter. Ultimately the conflict of the novella is resolved in an uplifting way which asserts the moral of the story, that 'it is important to remember past sorrows and wrongs so that you can then forgive those responsible and, in doing so, unburden your soul and mature as a human being.'
