The ABC Murders (1936) is one of Agatha Christie's most celebrated detective novels, featuring the brilliant Belgian detective Hercule Poirot. A mysterious killer, calling himself "ABC," sends taunting letters to Poirot before committing a series of murders across England. The victims and locations follow alphabetical order—Alice Ascher in Andover, Betty Barnard in Bexhill, Sir Carmichael Clarke in Churston—with an ABC railway guide left beside each body. As public panic grows, Poirot races to decode the pattern before the killer strikes again. In a masterful twist, Christie reveals that the alphabetical killings conceal a single, calculated murder disguised among random crimes.
