When a local aristocrat is discovered dead beside a trout stream, Inspector Roderick Alleyn must navigate the insular and dismissive social circles of a charming English village to identify a killer. The investigation forces Alleyn to contend with a cast of characters who view the murder more as a social inconvenience than a tragedy. As he attempts to extract the truth from the tight-lipped residents, he faces the logical challenge of untangling a web of long-standing local grievances and hidden motives. The narrative follows a traditional third-person perspective, emphasizing the methodical collection of clues and the psychological profiling of the suspects.

This work is frequently noted for its stylistic proximity to the golden age of detective fiction, particularly the works of Agatha Christie. The narrative relies on the interplay between the polished, observant Inspector Alleyn and the rigid, often oblivious social hierarchy of the village. Readers often highlight the author's ability to balance a grim crime with the detached, almost comedic irritation of the suspects involved. The book serves as a quintessential example of the classic whodunit, where the atmosphere of the setting is as vital to the mystery as the evidence itself.
