This BBC Radio FullCast dramatization of one of Agatha Christie's most imaginative mysteries stars John Moffatt as the great Belgian detective, Simon Williams as his faithful sidekick Captain Hastings, and Philip Jackson as Chief Inspector Japp. Alice Asher, a poor, elderly shopkeeper, is murdered in Andover. Betty Barnard, a young waitress, is strangled with her own belt at BexhillonSea. Next comes Carmichael Clarke, collector of Chinese art, clubbed to death in Churston. Only in Doncaster does the pattern vary: the man found stabbed to death in the Regal Cinema is called George Earsfield. But each time, an ABC railway guide is found by the dead bodies, and each time, Poirot is warned in advance by a taunting letter from someone signed ''ABC''.
