The Enola Holmes Mysteries is a young adult fiction series of detective novels by American author Nancy Springer, starring Enola Holmes as the 14-year-old sister of an already famous Sherlock Holmes, twenty years her senior. There are nine books in the series, and one short story all written from 2006–2023. This pastiche series borrows characters and settings from the established canon of Sherlock Holmes, but the Enola character is Springer's creation and specific to this series.
