Published as a shilling shocker, Robert Louis Stevensons dark psychological fantasy gave birth to the idea of the split personality. The story of respectable Dr Jekylls strange association with damnable young man Edward Hyde, the hunt through fog-bound London for a killer, and the final revelation of Hydes true identity is a chilling exploration of humanitys basest capacity for evil. The other stories in this volume also testify to Stevensons inventiveness within the gothic genre: Olalla, a tale of vampirism and tainted family blood, and The Body Snatcher, which shows the murky underside of medical practice.
