Paul Temple's Triumph

Andrew Leigh has been working on his secret formula -- what does it do? Shut up, he explained -- when a couple of henchmen show up, threaten his daughter, and eat his biscuits without asking. They're working for the Z organization, a bunch of spies who sell their secrets to the highest bidder. Somehow, John Bentley and Dinah Dinah Sheridan as mystery writer Paul Temple and his wife Steve wind up at the hotel where the spies and police chasing spies congregate. Can Temple and company stumble their way to success in less than eighty minutes? It is to laugh.

It's based on one of the radio show's serial that originally aired in November and December of 1939, doubtless changed from Nazi agent to something that suggests The 39 Steps without much humor. With Jack Livesey, Jenny Mathot, and Leo de Pokorny in his final screen performance.
