The Queen sends Georgie to the French Riviera to recover a stolen royal snuffbox from an unscrupulous Englishman. In Nice, Georgie is drawn into the fashionable world of casinos, parties and couture when Coco Chanel asks her to model a new design, while Darcy’s appearance with another woman adds a personal complication.
Before Georgie can retrieve the snuffbox, a member of the Riviera circle is murdered and evidence begins to connect the death with the stolen object. Georgie must move between servants, socialites and suspicious expatriates to recover the royal property and identify the killer.
