The Strange Case of Dr Jekyll and Mr Hyde

The Strange Case of Doctor Jekyll and Mister Hyde was a novel by Robert Louis Stevenson, (AUDIO: Medicinal Purposes) released soon before the 1890s. (AUDIO: Stage Fright)

In 1828, Doctor Robert Knox alluded to the novel during a conversation with Evelyn Smythe. Given that Stevenson would not be born until the 1850s, the Sixth Doctor realised that he mentioned the novel as a test for Evelyn whom he correctly believed may be another time traveller.

Henry Gordon Jago and George Litefoot were familiar with the book in the 1890s, and suggested that it needed a theatre revival. (AUDIO: Stage Fright)

The character of Mr Hyde existed in the Land of Fiction, as one of the members of the Sisyphean Society's senior circle. (COMIC: Character Assassin)
