Robert Louis Stevenson's thrilling tale of the mild-mannered Dr. Jekyll and his evil double, Mr. Hyde, is one of the most famous horror stories in English literature. It is also a profound and fascinating fable of the divided self that continues to seize readers' imaginations. This story of a misguided genius who brings his doppelg nger to life brilliantly dramatizes inner conflict and the capacity for violence and evil in every soul. An instant sensation on its first publication in 1886, Stevenson's spine-chilling novella has given rise to countless adaptations on stage and screen over the past century, but none can match the power and dark complexity of the original.
