Enola Holmes

Sherlock's little sister proves to be no mean sleuth herself in this fun adventure, based on the popular novels by Nancy Springer and starring a headstrong Millie Bobby Brown in the title role. Free-spirited Enola awakes on her 16th birthday to find her mother (Helena Bonham Carter) missing, leaving behind an odd assortment of gifts but no apparent clue as to where she's gone or why. Against the wishes of her elder brothers (Henry Cavill as the famous detective, Sam Claflin as the stuffy Mycroft), she absconds from her uptight finishing school and sets out to solve the mystery. It's a knockabout yarn that never takes itself too seriously, blessed with a witty script and taut action. There's so much to enjoy in Brown's captivating central performance, especially her numerous asides to camera that take the viewer along for the ride. The plot may be a little sticky in places, but the occasional hiccups don't hang around, and as the opening salvo in a potential franchise it'll do just nicely.
