The ABC Murders is an adventure and investigation game adapted from the classic Agatha Christie novel. You are the famous private detective Hercule Poirot and, once again, you find yourself up against a mysterious serial killer who goes by the name of "ABC".

Agatha Christie: The ABC Murders is a point-and-click detective adventure that casts players as the legendary Belgian sleuth Hercule Poirot. Adapting Christie's classic novel, the story begins when Poirot receives taunting letters signed "ABC," each foretelling a murder in a town whose name matches the killer's alphabetical pattern. As the bodies mount, Poirot travels across England to examine crime scenes, interrogate suspects, and piece together clues left in the wake of a cunning and methodical killer. Players must exercise the detective's famous powers of observation and deduction to unmask the culprit before the deadly sequence can continue.
