The doppelganger, or the ghostly double infecting the soul, was a popular fictional subject for late nineteenth-century writers, and it found its most brilliant realization in Robert Louis Stevenson's story of Dr. Jekyll, whose reckless genius allows him to bring his own appalling double to life. Dr. Jekyll's attempts to purify himself by creating a drug by which to separate the good and evil inherent in all humans results in the appearance of the murderous Mr. Hyde. When a curious lawyer begins to investigate, the connection between Jekyll and Hyde becomes clearer, and the danger and suspense intensify. The finest horror story in our language, Dr Jekyll and Mr Hyde is also a metaphysical fairy tale of stunning perspicacity. Also included in this collection are "Markheim," "A Lodging for the Night," "Thrawn Janet," "The Body-Snatcher," and "The Misadventures of John Nicholson."
