Dr. Jekyll has been experimenting with identity. He has developed a drug which separates the two sides of his nature, allowing him to abandon himself to his most corrupt inclinations as the monstrous Mr. Hyde. But gradually the journey back to goodness becomes more and more difficult, and the risk that Mr. Hyde will break free from Dr. Jekyll's control puts all of London in grave peril. This groundbreaking tale of identity and morality is accompanied by several other of Stevenson's best short stories, including "The Body-Snatcher," "A Lodging for the Night," "Markheim," "The Misadventures of John Nicholson," and "Thrawn Jane."

Robert Louis Stevenson was born in Edinburgh in 1850. Chronically ill with bronchitis and possibly tuberculosis, Stevenson withdrew from Engineering at Edinburgh University in favour of Studying Law. Although he passed the bar and became an advocate in 1875, he knew that his true work was as a writer.

Between 1876 and his death in 1894, Stevenson wrote prolifically. His published essays, short stories, fiction, travel books, plays, letters and poetry number in dozens. The most famous of his works include Travels With A Donkey in the Cevennes (1879), New Arabian Nights (1882), Treasure Island (1883), The Strange Case of Doctor Jekyll and Mr Hyde (1887), Thrawn Janet (1887) and Kidnapped (1893).

After marrying Fanny Osbourne in 1880 Stevenson continued to travel and to write about his experiences. His poor health led him and his family to Valima in Samoa, where they settled. During his days there Stevenson was known as 'Tusitala' or 'The Story Teller'. His love of telling romantic and adventure stories allowed him to connect easily with the universal child in all of us. 'Fiction is to grown men what play is to the child,' he said.

Robert Louis Stevenson died in Valima in 1894 of a brain haemorrhage.
