The Judas Tree (Jonathan Creek)

"The Judas Tree" is the twenty-seventh episode of the British crime drama series Jonathan Creek. The feature-length episode was written and directed by series creator David Renwick, and premiered on BBC One on 4 April 2010. The episode focuses on a series of mysteries surrounding housekeeper Emily Somerton (Natalie Walter), including a vanishing house and the murder of her employer Harriet Dore (Sasha Behar). Alan Davies returns as the series' titular sleuth, Jonathan Creek, while Sheridan Smith reprises her role as his assistant Joey Ross, and Stuart Milligan returns as Jonathan's boss, magician Adam Klaus.

Financial constraints at the BBC delayed broadcast of the episode from January until April 2010. Davies' fee for the episode was reduced by 25 per cent, and the production's design budget was also subject to a significant reduction, as the BBC attempted to achieve efficiencies with the show. The episode was watched by 5.45 million viewers, and received mixed reviews from critics. David Brown of the Radio Times and Vicky Frost of The Guardian both praised the plot and Davies' performance, however Paul Whitelaw of The Scotsman felt that the series ought to be retired.
