The new Christmas special is called "The Grinning Man" and starts filming at the end of June 2008. As expected Julia Sawalha will not be reprising her role as Carla Borrego and nor will Caroline Quentin be returning as Maddy Magellan. Instead Alan Davies will be joined by Sheridan Smith, an actress who is no stranger to the writings of David Renwick having starred in Love Soup with Tasmin Greig.
Sheridan will play Joey Ross a woman described as "fearlessly sceptical" in the BBC press release.
From the BBC press release:-
"When Creek is called in to solve unexplained events in a vast Gothic house, following several disappearances inside a gloomy old attic known as "The Nightmare Room", he is completely baffled.
For 70 years the room has been claiming lives. Could the ghost of a madman who preys upon human flesh really be to blame?
When two young women take shelter there from a raging thunderstorm one night, it's not long before the ominous "presence" has claimed another victim.
Determined to get to the truth about what has happened to her friend, the fearlessly sceptical Joey Ross (Sheridan Smith) finds herself working alongside veteran lateral thinker Jonathan Creek. Together they embark on a complex, often dangerous, investigation into a mystery which only continues to deepen...
Can Jonathan Creek once again shed light on the riddle and render the impossible possible? Or are his once formidable powers of deduction about to be eclipsed by the raw intuition of his younger counterpart?"
