The Agatha Christie Hour: The Mystery of the Blue Jar/The Red...

Two episodes of the early 1980s BBC drama series based on the short stories of crime writer Agatha Christie.

In 'The Mystery of the Blue Jar', trainee solicitor Jack Hartingdon (Robin Kermode) hears a woman's voice crying for help while he's playing golf.

When local resident Felise (Isabelle Spade) claims that she too has heard the voice and seen the ghost of a murdered woman holding a blue jar, Jack's friend Dr Lavington (Michael Aldridge) arranges a seance in Felise's cottage.

But is there really a ghost - or is Jack the victim of a cunning trick? In 'The Red Signal', Dermot West (Richard Morant) is invited to dinner at the home of Jack and Claire Trent (Christopher Cazenove and Joanna David) along with his famous psychiatrist uncle, Sir Alington West (Badel).

When the doctor is mysteriously killed following a conversation about supernatural forces and premonitions, Dermot finds himself a prime suspect along with his best friend's wife, Claire, with whom he is secretly in love.
