Don't miss this fast-paced thriller on BBC Radio 4 on Saturday 26th March at 2:30pm, starring Claire Foy, Blake Ritson and Charlie Cox; directed by Sasha Yevtushenko.

This taut, character-driven conspiracy thriller, writhing with twists and heavy on menace, will be compelling Saturday afternoon entertainment.

David and Helen, a professional couple in their mid-twenties, are shocked when Jamie, an old friend from university, dies unexpectedly. At the funeral, they meet Mark, another mutual friend. Mark implies that he works for Special Services, and tells them that Jamie, a high-flying investment banker, may have killed himself - and that his bank has been under investigation. Did Jamie contact the couple before he died? As Mark teases out information, Helen begins to suspect he is not entirely innocent. Mark's questions turn into threats, and people start getting hurt. David and Helen find they must expose a murder before it's too late.

The lead roles are played by three top young British actors; Claire Foy (THE PROMISE, LITTLE DORRIT), Charlie Cox (STARDUST, DOWNTON ABBEY) and Blake Ritson (UPSTAIRS DOWNSTAIRS, ROMANTICS and the lead in Radio 4's four-week serial THE FAR PAVILIONS, Feb 2011).

Simon Passmore has had a string of recent successes on radio with ACCOMPLICES, OFFSHORE and GOING TO GROUND.
