Robert Louis Stevenson's immortal tale of personality and evil, now in a wonderful new clothbound edition 'All human beings, as we meet them, are commingled out of good and evil: and Edward Hyde, alone in the ranks of mankind, was pure evil' Published as a 'shilling shocker', Robert Louis Stevenson's dark psychological fantasy gave birth to the idea of the split personality. The story of respectable Dr Jekyll's strange association with 'damnable young man' Edward Hyde; the hunt through fog-bound London for a killer; and the final revelation of Hyde's true identity is a chilling exploration of humanity's basest capacity for evil.

Stevenson's famous exploration of humanity's basest capacity for evil Dr. Jekyll and Mr. Hyde have become synonymous with the idea of a split personality. More than a morality tale, this dark psychological fantasy is also a product of its time, drawing on contemporary theories of class, evolution, criminality, and secret lives. Also in this volume are "The Body Snatcher," which charts the murky underside of Victorian medical practice, and "Olalla," a tale of vampirism and "the beast within," with a beautiful woman at its center.

Everyone has a dark side. Dr Jekyll has discovered the ultimate drug. A chemical that can turn him into something else. Suddenly, he can unleash his deepest cruelties in the guise of the sinister Hyde. Transforming himself at will, he roams the streets of fog-bound London as his monstrous alter-ego. It seems he is master of his fate. It seems he is in complete control. But soon he will discover that his double life comes at a hideous price...

Dr. Jekyll invented a drug that would change him into the ominous Mr. Hyde. His evil nature, however, became the stronger part of him and to his horror, he no longer needed the formula to transform his appearance.
