Marguerite de Fleurignac, once a glittering aristocrat in a world of privilege, is on the run, disguised as Maggie Duncan, British governess. Penniless and alone, cornered by fanatics of the revolution, she falls into the hands of a compelling stranger. There's no chance this menacing rogue with the rough voice and the sinister scar is an innocent bookseller. Why does he risk his life to save her? William Doyle, England's top spy, has a cunning plot to foil and a score to settle with the de Fleurignacs. When he pulls Maggie from the charred ruins of her chateau, he knows her for what she is -- the final, dangerous flower of a noble line. He's ruthless enough to use her for his own ends. And Maggie has come up with some interesting plans for Doyle. As they're drawn inexorably into the intrigue and madness of revolutionary Paris, they gamble on a love neither of them will admit. When the dance of deception and desire is over, which one of them will betray the other?
