This is a BBC Radio 4 full-cast dramatization starring John Moffatt as the great Belgian detective.
Hercule Poirot and his good friend Captain Hastings are enjoying a well-deserved break on the Cornish Riviera, in the idyllic village of St Loo.

The girl is Nick Buckley, last in a long line of Buckleys to live at End House, an isolated old place perched on the end of a rocky outcrop.
As she reassures the two friends that living there is more fun than it might seem, Poirot's ears prick up - she is having fun, Nick says, despite the fact that she has had three near-fatal accidents in the past few days.
