“The Mysterious Affair at Styles” marks the grand entrance of Agatha Christie into the world of detective fiction, introducing the Belgian detective Hercule Poirot, whose keen observation and brilliant deductive skills would captivate readers for decades.

Published in 1920, this novel not only set the stage for many of Christie’s later works but also defined the conventions of the classic detective story. Set against the backdrop of World War I, the narrative unfolds in a quintessential English country house, Styles Court, where family tensions, secrets, and the eventual murder of Emily Inglethorp stir the plot.

Plot Summary

The story is narrated by Captain Arthur Hastings, who, while recuperating from injuries sustained during the war, finds himself entangled in a mysterious murder case at Styles Court, the estate of his wealthy friend, John Cavendish. The Cavendish family matriarch, Emily Inglethorp, is found poisoned, and the peculiar circumstances of her death prompt the involvement of Hercule Poirot, a former Belgian police officer and a refugee residing nearby.

Poirot’s methodical and meticulous approach to solving the crime—examining alibis, motives, and physical evidence—leads him through a maze of clues and red herrings, culminating in a surprising denouement where the true murderer and their ingeniously concealed method are revealed.


The novel is populated by a cast of characters that are as diverse as they are intriguing. Hercule Poirot, with his distinctive ‘little grey cells,’ brings a methodical and peculiar charm to the investigation, contrasting with Hastings’ often naive and impulsive nature.
