Richard St. John, the Earl of Blackwood, operates in the shadows. To bring down a traitor, he requires the ultimate shield: a wife.
It is a cold calculation, a marriage of convenience designed to deflect suspicion from his covert operations against the French. He chooses a woman of sharp intellect and quiet beauty, intending a partnership on paper only. But as they navigate the treacherous waters of high society espionage, the calculated distance between them crumbles.
Forced proximity and shared danger ignite a passion neither anticipated. When the mission threatens to destroy them, Richard must decide what matters more: his duty to the Crown, or the woman who has captured his heart.
