Written by Agatha Christie. Adapted by Archie Scottney.

Martin Jarvis reads this intriguing 1920s story by the undisputed queen of Crime. Mr Satterthwaite is holidaying on a Spanish Island. One day he proceeds from the hotel to the small harbour. He passes the black lava beach where the surf thunders and where, long ago, an English swimmer was carried out to sea and drowned.

High up, on the edge of the cliff, is a white villa with faded green shutters, and a tangled beautiful garden. Today Mr Satterthwaite's peace is going to be oddly shattered. Something strange and frightening once occurred in this house. But will it take Mr Harley Quin's influence over Satterthwaite to discover the truth? Christie considered this character to be her personal favourite.
