Agatha Christie's The A.B.C. Murders is the tale of a serial killer who murders victims alphabetically by name and place of residence. Against this killer is Hercule Poirot, Christie's most famous detective, who uses logic and character insight to solve crimes.

The third murder in this story, that of Sir Carmichael Clarke, occurs at his home in the village of Churston. The killer's letter alerting Poirot to the planned murder was intentionally misdirected and delayed for three days to prevent Poirot from stopping the murder. The wealthy Clarke was killed by a heavy blow to the head as he took his habitual evening walk.

By this point in the novel, Poirot has gathered a team of earlier victims's relatives to help him with the investigation. When he interviews Clarke's brother and his secretary, the latter is eager to help Poirot. In those family relationships lies the key not only to Clarke's murder but to the entire ABC murder spree: with Clarke's wife dying of cancer, he would probably soon remarry to his secretary and leave her his wealth rather than leaving his fortune to his brother. Clarke's brother planned the series of alphabetical murders not only to hide the fact that his brother was the true targeted victim, but also to place blame on an innocent but unstable salesman who worked as his pawn.

Poirot's questioning cleverly uncovers motives and clues over the course of the investigation. Now that you know whodunit, can you spot how Poirot solves the murders?
