Sheridan Smith will be returning to her role as Joey Ross for another Jonathan Creek special

The episode, which is the first Creek to air since 2010's 'The Judas Tree' special, is titled 'The Clue of the Savant's Thumb' and will star its fair share of special guests to go with the two main stars. As well as Davies and Smith, notable actors and actresses Joanna Lumley, Sarah Alexander, Rik Mayall and Nigel Planer will also be taking on roles for this one-off special. The 90 minute show will include all the gripping and sometimes gruelling details that made the show such a hit during the original run, with this episode following Creek as he investigates the disappearance of a dead body from a locked study located in a haunted Catholic girls' school and a local society that seems to have more to offer than initially meets the eye.

The show will air on BBC tonight at 8.30 pm (GMT) and is the latest in a series of one off special made by the BBC featuring Davies and Smith as the lead roles. The initial Jonathan Creek series ran from 1997 until 2004 and featured Davies alongside Caroline Quentin and Julia Sawalha, achieving a notable following during it's time on air.
