Dr Jekyll and Mr Hyde

It is when Mr Utterson, a dry London lawyer, peruses the last will of his old friend Henry Jekyll that his suspicions are aroused. What is the relationship between upright/respectable Dr Jekyll and the evil Edward Hyde? Who murdered the distinguished MP, Sir Danvers? So begins Stevenson's spine-tingling horror story, the story of Dr Jekyll's infernal alter ego, and of a hunt throughout the nocturnal streets of London that culminates in some dreadful revelations.
