From New York Times bestselling author Candace Camp comes an exciting Regency adventure, where a slow-burning love affair collides with a complex mystery… After the scandal of his broken engagement, Nathan Dunbridge accepted his fate as a bachelor—so of course that’s when the most ineligible woman of all turns up in disguise at a society event: Verity Cole, former spy and Stonecliffe’s resident troublemaker… a woman Nathan finds equal parts alluring and irritating. Living in London under an assumed name, Verity runs an investigation agency. So when a stranger shows up claiming to be the rightful Dunbridge heir, Nathan turns to Verity to help him uncover the truth. Verity agrees, always eager to unravel a mystery—especially when it involves the handsome Nathan Dunbridge. As Nathan’s family secrets threaten everything he’s known, he finds Verity is the only person he wants to confide in. But Verity has secrets too—secrets that make it impossible to be with a proper gentleman like Nathan. And when an enemy from her past appears, will Nathan and Verity be able to hold on to their impossible love, or will they be torn apart?
