In the glittering world of Regency London, Lord Lucas Cambridge, the Marquess of Winchester, is a man of secrets and intrigue. Having fought in the Peninsular War and serving the British Home Office in the shadows, he is a cynical and devilish rake who scoffs at the notion of marriage. But when his meddling family plots to ensnare him in their matrimonial schemes, he seeks refuge behind a ballroom curtain, only to discover a mysterious woman hiding there. She seems familiar and intrigues him like no other.

Caitlin Drummond, a wallflower on her third season in the marriage mart, dreams of escaping the relentless matchmaking efforts of her stepmother. As the secret apprentice to a progressive physician, she views the eligible bachelors with disdain, knowing the vices they indulge in behind closed doors. When Lucas Cambridge becomes intrigued by her familiar eyes, Caitlin is determined to keep her distance. For if he uncovers the truth of their previous encounter, it could destroy the carefully constructed life she has built for herself.

From the extravagant ballrooms of London to the gritty underbelly of the rookeries, follow Lucas and Caitlin as they navigate their way through a delicate dance of danger, espionage and romance.
