Dr. Jekyll believes that evil burdens every soul, so he creates a drug to rid himself of evil. But little does he know, each time he takes to drug, the evil within him starts to grow more powerful. A London lawyer named Gabriel John Utterson investigates the strange occurrences between his old friend, Dr. Henry Jekyll, and the evil Edward Hyde. The Strange Case of Dr. Jekyll and Mr. Hyde is commonly associated with the rare mental condition often called "split personality," referred to in psychiatry as dissociative identity disorder, where within the same body there exists more than one distinct personality. In this case, there are two personalities within Dr. Jekyll, one apparently good and the other evil. The book's impact is such that it has become a part of the English language, with the very phrase "Jekyll and Hyde" coming to mean a person who is vastly different in moral character from one situation to the next.
