Provincial France, 1793. Fleurette has grown up at a distance from Parisian politics, but the Law of Suspects reaches her village when revolutionary troops begin searching homes and arresting anyone connected with the former aristocracy. Her concern for a neighbouring family and her own concealed parentage make her vulnerable to denunciation, while the man she believes to be her father carries secrets tied to Chauvelin.
Sir Percy enters a landscape where local grudges can be converted into accusations of treason and where even the innocent may be trapped by association. His rescue plan must protect Fleurette and the threatened household without revealing the full network of the League. The novel gives Chauvelin a personal stake in the consequences of revolutionary justice, compelling Percy to save people connected to his old enemy as well as those he would normally regard as allies.
