Description

At a Cornwall dinner party hosted by retired stage actor Sir Charles Cartwright, a guest dies after taking an apparently ordinary drink. No poison is found in the glass, leaving the death without an obvious cause. When another guest dies in strikingly similar circumstances, Cartwright joins Mr Satterthwaite, the young woman known as Egg, and Hercule Poirot in an investigation that moves across England. The survivors of the gatherings carry suspicious histories and possible motives, yet the missing poison and uncertain connection between the victims resist a simple explanation. Christie stages the mystery through social performances, repeated scenes, and misleading appearances, asking Poirot to determine whether two perplexing deaths belong to one carefully designed plot.

About Agatha Christie

Agatha Christie (1890–1976) was an English mystery writer associated with the Golden Age of Detective Fiction. After six rejections, she established her career in 1920 with The Mysterious Affair at Styles, which introduced Hercule Poirot. Much of her fiction places a limited group of suspects in a confined social setting, such as a country house, train, boat, or island, then tests their accounts against physical clues and private motives. Her direct, dialogue-led prose keeps these investigations clear while giving weight to discrepancies in testimony and behavior. Poirot exemplifies this attention to both material evidence and human conduct. Across her work, Christie returned to concealed relationships, guilt, unreliable witnesses, and the tension between establishing what happened and deciding what justice requires.
