In this powerful deconstruction of Calvinist belief and the hypocrisy at the heart of Victorian society, Stevenson creates a gothic icon in the divided self that is Dr Jekyll and Mr Hyde. Born from a nightmare and anticipating Freud`s theory of the unconscious, Stevenson literalises the concepts of the supernatural doppelganger and the split personality in a timeless tale of guilt, desire, and violence by which all subsequent `double` stories must be judged. In seeking to cleanse his soul of sin, Dr Henry Jekyll instead unleashes a monster. First published in 1886, this tragic study of the duality of man established Stevenson`s international reputation as an author.
