Folks in the UK may be au fait about this, but it’s news to me. Bookish, a new six-part murder mystery series created, starring, and written by Mark Gatiss (Sherlock, The League of Gentlemen), will premiere January 11 on PBS, with new episodes released every Sunday through February 15. Directed by Carolina Giammetta, the series is co-written by Gatiss and Matthew Sweet.

PBS noted that Gatiss and director Carolina Giammetta take viewers “into the chaotic and dangerous shadows of post-war 1946 London, where Gabriel Book’s [Gatiss] encyclopedic knowledge of literature and history makes him an invaluable–if unconventional–consultant to the local police. With razor-sharp wit and an entourage of charming social misfits, Book helps unravel London’s most puzzling mysteries by turning to the thousands of books lining his shelves.”

Polly Walker (Bridgerton, Line of Duty) stars as Trottie Book; Connor Finch (Everything I Know About Love) as Jack; Elliot Levey (We Were the Lucky Ones, Quiz) as Inspector Bliss; Blake Harrison (World on Fire, Still Up) as Sergeant Morris; and Buket Kömür (Our House) as Nora.
