Evan Placey's Jekyll & Hyde is a radical re-imagining of Robert Louis Stevenson’s 1886 gothic novella, Strange Case of Dr Jekyll and Mr Hyde. It was commissioned by the National Youth Theatre of Great Britain, and first performed by the company at the Ambassadors Theatre, London, on 27 September 2017.

The play opens in the Victorian period, after the death of Dr Jekyll (the culminating event in Stevenson's novella). Jekyll's widow, Harriet, is trying to continue her late husband's work, which results in her developing an alter ego as a violent, forthright prostitute, Flossie Hyde, who isn’t going to be exploited by anyone. But the world of the story is increasingly disrupted by glaring anachronisms until, at the end of Act One, the twenty-first-century world breaks through in the form of a new plot concerning a young woman called Florence Monroe, who is blogging a story about Harriet Jekyll, and using it to incite rebellion and public violence against patriarchal authority.
