David Suchet stars as the fastidious Belgian detective Hercule Poirot in this made-for-TV adaptation of the classic mystery by Agatha Christie. A killer is on the loose who is toying with the great sleuth by sending him a series of letters in which he announces when and where his next crime will occur. Can Poirot discover who is the criminal and determine his motive before he kills again? Poirot: The ABC Murders was originally aired in the U.S. on the PBS series Mystery! The supporting cast includes Philip Jackson as Inspector Japp and Hugh Frasier as Capt. Hastings. ~ Mark Deming, All Movie Guide
