She can hide from him no longer...

Perpetually vexed by his misbehaving niece, the Marquess of Camden and Spymaster to the Crown is putting his foot down once and for all. Though Miss Evie Stuart refuses a debut, her dear Uncle Oliver insists that she formally enter noble society this Season. Evie would prefer to continue the years-long search for the traitor in their midst, but following the available clues leads her to concede that a Season by her uncle's side might bring her ever closer to her ultimate goal. As the traitor hides among Society, Evie will reluctantly assume her ultimate role as a Lady of the Ton.

After much confusion and frustration, Captain Anthony Browne finally learns the identity of the mysterious tart who saved his life in a French brothel four years ago. But the last place he expected to find the lovely lightskirt with whom he shared a single night of pleasure is at the Marquess of Camden's side, where she is announced as the Spymaster's niece. With only one honorable way forward, Anthony accepts his fate. Taking a bride was not in his plans, but he could do much worse than an adventuress who shares his goal of finally capturing the traitor, and doesn't mind testing his desire for control.

Evie, however, has no intention of marrying, even if the domineering Captain is the one man she has never been able to forget. Her only wish is to beat him and everyone else to the traitor. Though the competition between them is fierce, their attraction is even more powerful, and a scintillating scandal threatens to force them together 'til death do they part.
