"1797. The war with France deepens, the Channel Fleet has mutinied ... and a ruthless traitor lurks within fashionable London society. A chance encounter places an unlikely sleuth on his trail: Mary Finch. Having gained a fortune but lost the regard of Captain Robert Holland, she wants only to enjoy the delights of the Season, yet she cannot ignore the evidence of a deeper mystery. Her curiosity leads to a meeting with an elusive spymaster and an audacious proposal. With England's security and a friend's safety at risk, Mary agrees to become a guest at the exotic Champian Hall, to learn the traitor's secrets from within his household. The assignment is a perilous one, for it aims to unmask a band of murderous conspirators who will stop at nothing to achieve their aims - and Mary has only her wit and courage for protection."--Publisher description.
