Sherlock Holmes’s little sister is coming to our screens, and Stranger Things actress Millie Bobby Brown will be playing her.

If that’s not welcome enough casting, Henry Cavill is set to make for a super Sherlock, while Helena Bonham Carter will portray Enola’s mum.

According to Variety, Enola Holmes is set to be based on the six-book series The Enola Holmes Mysteries by Nancy Springer.

It’s all sounding pretty cool, with the writer behind His Dark Materials and stage show Harry Potter and the Cursed Child, Jack Thorne, penning this one.

Production is expected to commence soon.
