In seeking to discover his inner self, the brilliant Dr Henry Jekyll discovers a monster. Developing a serum with the intent of separating his good side from his darker impulses, he periodically transforms into Edward Hyde, a brutal creature, free of any conscience. The scientist's strange behaviour is investigated by his friend, the lawyer John Utterson. What follows is a classic thriller, and a terrifying study of the duality of human nature. Also included in this collection are five other classic tales of mystery and horror, from some of the greatest writers of the era.
