Eleven linked stories follow Sir Percy Blakeney and the League as they rescue people threatened by revolutionary courts, prisons and local committees. The missions include divided families, children separated from parents, nobles hiding under false identities and League members whose courage is tested when the danger becomes personal. Each operation begins with limited information and a victim whose time is running out.
Percy rarely confronts authority directly. Instead, he uses rumours, forged documents, theatrical disguises and the assumptions of officials who expect fear to make their prisoners predictable. The collection broadens the series beyond Percy and Marguerite by showing the organisation’s reach and the costs borne by its agents. Its separate episodes share the conditions of the Reign of Terror, when rescue depends on moving through a bureaucracy designed to turn suspicion into execution.
