Idealistic young scientist Henry Jekyll struggles to unlock the secrets of the soul. Testing chemicals in his lab, he drinks a mixture he hopes will isolate - and eliminate - human evil. Instead it unleashes the dark forces within him, transforming him into the hideous and murderous Mr. Hyde. The Strange Case of Dr. Jekyll and Mr. Hyde dramatically brings to life a science-fiction case study of the nature of good and evil and the duality that can exist within one person. Resonant with psychological perception and ethical insight, the book has literary roots in Dostoevsky’s 'The Double' and Crime and Punishment. Today Stevenson’s novella is recognized as an incisive study of Victorian morality and sexual repression, as well as a great thriller.
