Regency England, August 1812: Sebastian St. Cyr's plans to escape the London heat for a honeymoon are ruined when the body of Gabrielle Tennyson, his wife's murdered friend, is found in a battered boat drifting near a long-vanished castle in a location known like Camlit-Mote. Miss Tennyson, a beautiful young antiquarian, recently caused a storm of indignation and controversy by declaring that ancient Camelot was located on this island. Also missing and presumed dead are Gabrielle's two young nephews, nine-year-old George and three-year-old Alfred. As the investigation moves from medieval inns of court to back alleys in London, from large country estates to rural communities where ancient Celtic beliefs still reign, Sebastian and Gero are trying to determine how their recently concluded marriage will turn out, and sometimes act against each other. Delving deeper into the case, Devlin uncovers dark secrets within the Tennyson family itself, and also finds a mysterious young French lieutenant with a dangerous secret. Rushing to expose the ruthless killer and unravel the mystery of the missing children, the newlyweds soon find that their lives and their growing love for each other are under threat , as their investigation leads them to Father Gero, Sebastian's longtime enemy... and a tall, dark stranger who may hold the key to the mystery of Saint-Cyr's origins.
