Colonel William Reid has returned home from India to retire near his children. Upon his return to the Isles, however, he finds that one of his daughters has vanished. Having served as second-in-command to the Pink Carnation, one of England's most intrepid spies, it would be impossible for Gwendolyn Meadows to give up the intrigue of Paris for a quiet life. But, when the Pink Carnation's little sister goes missing, Gwen reluctantly returns home to investigate the girl's disappearance. Thrown together by circumstance, Gwen and William must cooperate to track down the young ladies before others get their hands on them. But Gwen's partnership with quick-tongued, roguish William may prove to be even more of an adventure for her than finding the lost girls.
