The third movie follows Enola as she prepares for her impending wedding to Lord Tewkesbury in Malta.
However, her plans are upended when her brother, Sherlock, suddenly gets abducted. As she investigates the disappearance, she becomes entangled in a web of darker, more complicated mysteries.
The franchise is based on The Enola Holmes Mysteries, a series of novels written by Nancy Springer. Although the movie isn’t directly based on any single book, its basic premise resembles the third entry, The Case of the Bizarre Bouquets.
While the novel also focuses on Enola and Tewkesbury’s relationship, the central mystery revolves around Dr. Watson’s disappearance.

While Netflix hasn’t officially announced a fourth installment yet, the franchise could easily continue. With eleven installments in Springer’s book series, there is plenty of source material for a fourth film.
During an interview with Digital Spy, Brown addressed the possibility of Enola Holmes 4, admitting she would do it if Netflix were interested.
