A dedicated Pinkerton agent, Sarah Margaret "Yancey" Calhoun can't ignore an impassioned summons from the Dowager Duchess of Somerset, who believes Yancey is her son's estranged wife. Nothing could be further from the truth. But another woman named Sarah Calhoun has been murdered in Chicago. And Yancey could be next.
Traveling to England alone is hardly intimidating for a woman who works undercover. But when Yancey arrives at the remote country estate of Stonebridge, she is shaken to find that Samuel Treyhorne, the Duke of Somerset, is a force to be reckoned with—and a man who trusts her as little as she trusts him.
Masquerading as Sam's wife may be the only way to untangle the web of deceit that threatens both their lives. As Yancey's feigned affection for Sam becomes all too real, she must risk everything she holds dear...if she hopes to save the man she's come to love.
