When a routine favor for a colleague turns into a murder investigation, Archie Goodwin and Nero Wolfe must navigate a web of deceit to exonerate one of their own. Orrie Cather, a frequent associate of the firm, finds himself the prime suspect after his mistress is discovered dead in her apartment. Archie, having been sent to retrieve incriminating documents from the scene, becomes entangled in the investigation alongside his employer. Wolfe must apply his analytical rigor to untangle the victim's complicated romantic history while contending with the interference of a determined showgirl who has her own agenda. The narrative follows the classic Nero Wolfe structure, alternating between Archie's street-level legwork and Wolfe's sedentary, intellectual deduction.

This novel is widely regarded as a quintessential entry in the Nero Wolfe series, showcasing the established chemistry between the two leads. Readers often highlight the sharp, banter-filled dialogue that defines the interaction between Archie and Wolfe as a primary draw. The introduction of Julie Jacquette is frequently noted for providing a rare, formidable challenge to Wolfe's usual dominance in the investigative process. The work is characterized by its tight pacing and the clever, puzzle-like construction of the central mystery. It remains a staple for fans of traditional detective fiction who appreciate character-driven procedural narratives.
