Following the success of the first series of 'The Mysterious Mr Quin', Martin Jarvis reads more stories featuring Agatha Christie's personal favourite character.

Mr Quin assists his friend Mr Satterthwaite to investigate three mysteries. But one mystery remains - who is Mr Harley Quin himself?

Mr Satterthwaite, on holiday in Corsica, travels by car with his friend the Duchess and an Indian judge, to the top of the island known as The Worlds End. They are led, via perilous ravine lined roads, by Naomi, a young, strangely distracted artist.

In a village at the summit they suddenly encounter Mr Quin and, whilst sheltering from a sudden snowstorm, another visiting group - a well-known actress, her husband and a theatre producer. The actress tells the story of her stolen opal and the young writer imprisoned for the offence. Naomi seems unexpectedly disturbed by the tale.

Has Mr Quin once again appeared in time to avert a possible tragedy?
