Strange Case of Dr Jekyll and Mr Hyde is an 1886 Gothic horror novella by Scottish author Robert Louis Stevenson. It follows Gabriel John Utterson, a London-based legal practitioner who investigates a series of strange occurrences between his old friend, Dr Henry Jekyll, and a murderous criminal named Edward Hyde.

Strange Case of Dr Jekyll and Mr Hyde is considered to be a defining book of the gothic literature genre. The novella has also had an impact on popular culture, with the phrase "Jekyll and Hyde" being used in vernacular to refer to people with an outwardly good but sometimes shockingly evil nature.

Stevenson had long been intrigued by the idea of how human personalities can reflect the interplay of good and evil. While still a teenager, he developed a script for a play about William Brodie, a Scottish cabinet-maker, deacon of a trades guild, and Edinburgh city councillor, who maintained a secret life as a burglar in order to fund his mistresses and gambling addiction, which Stevenson later reworked with the help of W. E. Henley and which was produced for the first time in 1882.[5][6]

Inspiration may also have come from the writer's friendship with an Edinburgh-based French teacher, Eugène Chantrelle, who was convicted and executed for the murder of his wife in May 1878.
