A Case for the Bishop is the first episode of the British television series The Secret Service.

It's a case for the Bishop when a foreign ambassador plans to leave the country with a stolen computer prototype. The Bishop contacts Father Stanley Unwin, who minimizes Matthew and stows him away in the Ambassador's aircraft. After the plane takes off, Matthew switches off the engines. The plane is forced to land in a deserted airfield, where the Ambassador is confronted by Father Unwin, who soon recovers both the stolen computer prototype and Matthew.
