Which author created The Enola Holmes Mysteries book series?

Nancy Springer created The Enola Holmes Mysteries book series. Her novels introduced Enola Holmes, the teenage younger sister of Sherlock and Mycroft Holmes, years before the character appeared in the Netflix films.

The series began with The Case of the Missing Marquess in 2006. Enola is not a character created by Arthur Conan Doyle, even though she belongs to the Holmes family and lives in the same Victorian detective world. Springer built a new protagonist around the gaps in Doyle’s original stories, imagining a fiercely independent young investigator with her own cases and voice.

Netflix’s films adapt and expand the premise of Springer’s books rather than simply retelling a Sherlock Holmes story. The first movie draws particularly on The Case of the Missing Marquess, while the screenplays were written by Jack Thorne. Springer’s series earned Edgar Award nominations, helping establish Enola as a significant modern addition to the Holmes literary tradition.
