A new Sherlock Holmes spin-off is coming to Netflix, except the pipe-smoking deerstalker-capped super-sleuth isn’t the star of this film.

Instead, this is a story about Sherlock's younger sister, Enola Holmes, who will be played by Stranger Things star Millie Bobby Brown.

Netflix announced that it had acquired distribution rights to Enola Holmes in a tweet on Tuesday, April 21. The streaming giant did not give an exact date as to when the film will be released on the platform but did say it would be sometime in the third quarter of the year.

The film, which was made by Legendary Entertainment, is based on Nancy Springer's book series The Enola Holmes Mysteries. Directed by Fleabag's Harry Bradbeer, the film tells the story of Enola – who is every bit a super detective like her older brother – who sets out to find their missing mother, played by Helena Bonham Carter, who mysteriously disappears on her 16th birthday.

Enola asks her brothers for help but Sherlock and Mycroft, played by Henry Cavill and Sam Claflin respectively, seem more interested in sending her off to a boarding school.

Realising she can’t depend on her brothers, Enola runs away to London to find her mother, meeting a troupe of memorable characters along the way.

Season four of Brown's Netflix series Stranger Things was also due to hit the platform later this year. But as production, which was due to begin in February, was postponed due to the coronavirus pandemic, its release date will almost likely be pushed back to next year as well.
