Strange Case of Dr. Jekyll and Mr. Hyde

Strange Case of Dr Jekyll and Mr Hyde was first published in 1886. It is about a London lawyer named Gabriel John Utterson who investigates strange occurrences between his old friend, Dr. Henry Jekyll, and the evil Edward Hyde. The novella's impact is so great that it has become a part of the 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.
