Four feature-length murder mysteries starring David Suchet as moustache-twirling Belgian detecive Hercule Poirot. In 'The Clocks' (2009), typist Sheila Webb (Jaime Winstone) arrives at 19 Wilbraham Crescent in Dover to find a well-dressed corpse surrounded by five clocks, each one set to a different time. Could there be a connection with the recent discovery of a German mole within the Navy? In 'Three-Act Tragedy' (2010), retired actor Sir Charles Cartwright (Martin Shaw) invites thirteen guests for dinner. By the end of the evening one of the guests is dead, apparently poisoned - but the complete lack of an apparent motive leaves Poirot perplexed. In 'Halloween Party' (2010), Poirot is reunited with his old friend, crime novelist Ariadne Oliver, (Zoe Wanamaker), to investigate the drowning of two children at a Halloween party. In Agatha Christie's best-known mystery 'Murder on the Orient Express' (2010), Poirot must eliminate a long list of suspects to find the real killer after businessman Samuel Ratchett (Toby Jones) is found stabbed to death on the luxury rail route The Orient Express. Samuel West, Hugh Bonneville, Eileen Atkins and Barbara Hershey co-star.
