Written by the show’s creator David Renwick, the one-off 90-minute episode is due to air next Easter on BBC One.

‘The Clue of the Savant’s Thumb’ will see Creek and fellow investigator Joey Ross (Sheridan Smith) drawn into a complex case involving a secret society, seemingly supernatural events at a girls’ boarding school, and the miraculous disappearance of a body in front of three witnesses.

Alan Davies commented: “The new story has more than the usual amount of twists and surprises, and I’m very much looking forward to sleuthing again. I can’t wait to join Sheridan Smith on set again; we’re very lucky to have her. It’s nearly 17 years since I first auditioned for the part; the duffle coat is always on standby, even if the periods of duffle-hibernation are quite long these days”.

Pete Thornton, Creative Head, BBC In-House Comedy added: “A new Creek script from David is always a joy, and this one is especially brilliant. With the dream team of Alan Davies and Sheridan Smith back on board, we’re looking forward to delivering a really special Easter treat for BBC One audiences next year”.

Filming on ‘The Clue of the Savant’s Thumb’ will begin later this month.
