The gentleman spy

Summary: "When his father and older brother suddenly pass away, the new Duke of Haverly is saddled with a title he never expected to bear. To thwart the plans of his scheming family, the duke impulsively marries a wallflower. After all, she's meek and mild; it should be easy to sequester her in the country and get on with his life--as a secret agent for the Crown. But his bride has other ideas. She's determined to take her place not only as his duchess but as his wife. As a duchess, she can use her position to help the lowest of society--the women forced into prostitution because they have no skills or hope. Her endeavors are not met favorably in society, nor by her husband who wishes she'd remain in the background as he ordered. Can the duke succeed in relegating her to the sidelines of his life? When his secrets are threatened with exposure, will his new wife be an asset or a liability?"--
