An abridged version of the tale of a kind and well-respected doctor who can turn himself into a murderous madman by taking a secret drug he has created.

In Robert Louis Stevenson's influential novel of mad science and criminal inquiry, attorney Gabriel John Utterson comes to the aid of Dr. Henry Jekyll, an old friend, only to find himself dragged from a world of genial hospitality into London's foreboding night, which is shrouded in shadows and fog—and stalked by the deranged Edward Hyde. Utterson's quest for truth is not only a detective story laden with twists, but an intense meditation on man's inherently dualistic nature, written in a style that often combines disturbing violence with restrained language typical of the Victorian era.

The work is commonly associated with the rare mental condition often spuriously called "split personality", referred to in psychiatry as dissociative identity disorder, where within the same body there exists more than one distinct personality.[4] In this case, there are two personalities within Dr Jekyll, one apparently good and the other evil; completely opposite levels of morality. The novella's impact is such 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

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.

A kind and well-respected doctor can turn himself into a murderous madman by taking a secret drug he's created.
