John Fines, the Fifth Earl of Chatwin, is racing his horse in Hyde Park when he almost runs down a beautiful and alluring young woman. Lady Catherine Reynolds doesn't have time to dally about with infatuations— she's on a quest to find her real father. And when John is mesmerized by her, she takes up the opportunity to steal his horse right from under him, leaving behind a trail of gossip. Everyone in the town believes that Catherine has come to London to find a husband, but what she really needs is an ally who can help her uncover the truth. The dashing Lord Chatwin would have been the perfect gentleman to help her, if only she hadn't stolen his horse… and his heart.
