Robert Louis Stevenson’s classic novella paints a dark and complex tale about the duality of man’s nature. The story explores this contrast of human character through the strange case of Dr. Jekyll. A kind scientist by day, Jekyll discovers a way to transform into the form of Mr. Hyde by night. With a personality who carries all the hidden evil traits Jekyll disdains, Mr. Hyde becomes more difficult to control just as he perpetrates darker and more vicious deeds. Anticipating modern psychology, Dr. Jekyll and Mr. Hyde is a brilliant original study of man’s dual nature—as well as an immortal tale of suspense and terror. The book was an immediate success and remains one of Stevenson’s best-selling works.
