Proving her family innocent of treason is taking a toll on lady-turned-maid Juliet. Her latest investigation has brought her into the service of the spoiled Miss Dunbar and her salacious older brother, who pursues Juliet despite repeated rebuffs. Complicating matters further is the reappearance of Juliet's former beau who has not yet learned to do without her, and a growing attraction between herself and her brother's witty--and handsome--best friend. Even with these distractions, Juliet begins to piece together the events surrounding her brother's final days--and his connection to a mysterious figure named only as "H." But Juliet's ruse is under threat of revelation, and her blackmailer is one who will not hesitate to burn her unless she gives him what he wants: every document related to her brother's former role as a spy for His Majesty against the French.
