The doppelganger, 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. 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.
