The Strange Case of Dr. Jekyll and Mr. Hyde by Robert Louis StevensonRead about the other books on Martel's list.
Forget what you think you know about the story. It starts as a fairly conventional gothic horror story—until you get to the last chapter. There, you find one of the greatest descriptions in literature of the battle between good and evil in the human heart. We are all good Dr. Jekylls, and the moral question put to each of us by the novel is the same: What will you do with the evil Mr. Hyde lurking in you?
The Strange Case of Dr. Jekyll and Mr. Hyde also appears on John Mullan's list of ten of the best butlers in literature.
