When a young schoolmaster is discovered dead in a staged execution, Inspector Alec Stainton must navigate the insular and secretive environment of his former boarding school to identify the killer. Stainton returns to the grounds of his youth, where the rigid hierarchy of the institution complicates his investigation. As he interrogates both staff and students, he finds that the current tragedy is inextricably linked to a long-buried secret from the past. The narrative unfolds through a traditional investigative framework, focusing on the methodical peeling back of layers within a closed community.

This novel aligns with the conventions of the traditional British detective story, emphasizing a closed-circle mystery where the setting functions as a character itself. The narrative relies on the interplay between the inspector's past experiences and the current investigation to build tension. Readers likely find the school environment a fertile ground for exploring themes of tradition and hidden malice. The pacing remains steady, prioritizing the logical deduction of motives over rapid action sequences.
