A Case For The Bishop is the pilot episode of the British Supermarionation television series "The Secret Service". It was written by Gerry & Sylvia Anderson, directed by Alan Perry and was first broadcast in ATV Midlands on the 21st September 1969.

£1 million in used bank notes is travelling to London by express train. One attempt to steal the notes has already been made, so the Bishop assigns Father Unwin and Matthew to protect the train's cargo. After the train is hi-jacked, Unwin finds himself unable to stop the vehicle as it hurtles towards London at 80mph.

The Bishop assigns Father Unwin to protect the King of Muldovia during his visit to London, joining his retinue for a flight to New York where the King plans to visit his son. An attempt on the King's life is foiled by Matthew, but the Prince of Muldovia has hidden a bomb aboard the King's private plane and rigged a device that incapacitates the pilot and co-pilot.
