The cast for the forthcoming new episode of Jonathan Creek was revealed by the BBC today.
Starring alongside Alan Davies as Creek and Sheridan Smith as fellow investigator Joey Ross, pictured, in the 90-minute special The Clue of the Savant's Thumb will be Rik Mayall, returning as Detective Inspector Gideon Pryke, Sarah Alexander, Joanna Lumley, Nigel Planer, and Hasina Haque.
The episode, written and directed by David Renwick, sees Creek and Ross 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.
Filming is currently under way, with the action being shot in Sussex, Surrey, Hampshire, and Hertfordshire. The episode is due to air on BBC One this Easter.
