A kind and well-respected doctor is transformed into a murderous madman by taking a secret drug of his own creation. This book is about a lawyer who suspects that something is wrong with his dear friend Dr.Jekyll after his cousin tells him about "the blackmail house" and how that door leads into Jekyll's house. His cousin also tells him about the horrid man and the child he saw earlier that night. Also the will that Jekyll wrote to Lanyon (his lawyer) does not make any sense to him. This is a great book for all ages.

Robert Louis Stevenson : studied at Edinburgh, became a lawyer (1875), then turned to writing travel sketches, essays, and short stories for magazines. The romantic adventure story, Treasure Island (1883), brought him fame.
