Set in the bucolic English village of King’s Abbot, the novel is narrated by Dr. James Sheppard, physician to the area’s leading residents, one of whom is Roger Ackroyd, a wealthy industrialist. Sheppard is a bachelor who lives with his sister Caroline, an elderly spinster with a bent for gossip. Ackroyd, a widower, lives with his widowed sister-in-law, the penurious yet proud Mrs. Cecil Ackroyd. Her daughter Flora is engaged to marry Ralph Paton, Ackroyd’s penniless and irresponsible stepson.
Shattering the usual calm are two deaths, seemingly connected only by proximity of time and place, but in fact directly related.

All that was sound and wholesome and law abiding in him must have turned from her utterly in that moment....” She asked Ackroyd for twenty-four hours before he reported her crime, and during this period she committed suicide. While he was telling Sheppard the tale, the butler brought in the evening mail, which included a letter from Mrs. Ferrars, presumably identifying her blackmailer. Ackroyd set it aside to read after Sheppard left. When the police search the room after Ackroyd’s death, the letter is gone.
In the aftermath of the murder, a newcomer to the village enters the picture. The Larches, a house next to that of the Sheppards, has been rented by an elderly foreigner, thought to be a retired hairdresser but actually Hercule Poirot, the Belgian private...
