Enola Holmes ★★★½

The adventures of Sherlock Holmes's smarter sister, specifically sixteen year old Enola, bred to solve ciphers and fight.

Millie Bobby Btown is the new Holmes on the block,tiptoeing into politics and matters of disguise.

Henry Cavill swaps superheroes for Sherlock, while Sam Chaflin makes his Oswald Mosley from Peaky Blinders morph into a starchy Mycroft.

Trouble with the Conan Doyle estate aside, it is hard to see whether this will translate into any further adaptations. Watch this to enjoy Burn Gorman, Frances de La Tour, David Bamber and Fiona Shaw - plus, Sherlock alumni spotters, you may spot Jay Simpson from The Baker Street Boys in a teeny role.
