When the abrasive and wealthy Sybil Foster is murdered at a retreat for the elite, Inspector Roderick Alleyn must navigate a web of social pretension to uncover the killer. The investigation centers on the claustrophobic environment of a local hotel, where the victim's irritating personality and snobbish behavior provide a surplus of suspects. Alleyn, known for his methodical and gentlemanly approach, must sift through the motives of the victim's family and associates to distinguish genuine malice from mere social friction. The narrative follows the classic whodunit framework, emphasizing the interplay between class dynamics and the cold logic of criminal investigation.

This novel is widely regarded as a quintessential example of the Golden Age style of detective fiction, showcasing the author's mastery of the classic whodunit format. Readers often highlight the sharp characterizations and the intricate, puzzle-like nature of the mystery as the primary strengths of the work. The setting of the English village is utilized effectively to create a sense of insular tension that heightens the stakes of the investigation. As a late-career entry in the Alleyn series, the book reflects a refined approach to the genre that prioritizes clever plotting and social commentary over visceral action. The narrative maintains a consistent tone that appeals to those who appreciate the traditional conventions of British crime writing.
