Murder on the Orient Express (ABC) (Agatha Christie Poirot)

This eagerly anticipated adaptation of Agatha Christie's best-loved murder mystery is a star-studded production. Directed by BAFTA winner Philip Martin (Wallander), David Suchet returns as eccentric Belgian detective, Hercule Poirot.

Travelling from Istanbul to London on the famous Orient Express, Poirot is approached by ruthless businessman Samuel Ratchett (Toby Jones - Frost/Nixon), who offers him $10,000.00 to watch his back. Poirot refuses, but when Ratchett is stabbed to death he vows to find the killer. Aided by amateur sleuth Dr Constantine (Samuel West - Desperate Romantics), Poirot assembles an extensive list of suspects, including Ratchett's manservant Edward Masterman (Hugh Bonneville - Bonekickers), elderly Princess Dragomiroff (Dame Eileen Atkins - Cranford), and pushy Mrs Hubbard (Barbara Hershey - The Mountain).

The stakes are raised when the train gets stuck in a snowdrift. Cut off from civilization, Poirot's skills are tested to the limit. What was Ratchett frightened of? More importantly, is the assassin still on the train?
