Espionage! is a period comedy stage play set in London and Porthmadog in 1938.
A committee of military personnel with checkered histories has been mysteriously assembled by the British Secret Intelligence Service, ostensibly to flush out a mole suspected of sharing secrets with the Nazis. The action switches between this intriguing plot and the real-life story of the playwright who is writing this stage play, detailing his battles with the show's producer and investor as they race to meet a deadline for rehearsals and opening night. The characters in the play-within-a-play portray aspects of the characters in the over-arcing story line relating to the playwright and his employers, and are also used to verbalize the thoughts of the writer. This is a truly unique construct, making this a quite remarkable play.
