Radio's smoothest sleuth and his glamorous wife solve a case of international mystery.

From 1938 to 1969 crime novelist and detective Paul Temple and his Fleet Street journalist wife Steve solved case after case in one of BBC radio's most popular serials.

They inhabit a sophisticated, well-dressed world of chilled cocktails and fast cars, where the women are chic and the men still wear cravats. And where Sir Graham Forbes of Scotland Yard always needs Paul's help with a tricky case.

In this case, an aeroplane passing over Dulworth Bay, crashes into a cliff, while a row boat watches and waits, then heads for the shore.
