She's braved battlefields. She's stolen dispatches from under the noses of heads of state. She's played the worldly courtesan, the naive virgin, the refined British lady, even a Gypsy boy. But Annique Villiers, the elusive spy known as the Fox Cub, has finally met the one man she can't outwit...

British spymaster Robert Grey must enter France and bring back the brilliant, beautiful-and dangerous-Fox Cub. His duty is to capture her and her secrets for England. When the two natural enemies are thrown into prison, they forge an uneasy alliance to break free. But their pact is temporary and betrayal seems inevitable as the fates of nations hang in the balance.
