Inhalt: After participating in the Jacobite Rising of 1745, Robin and Prudence, brother and sister, become engaged in a swashbuckling, romantic adventure. Our hero and heroine must cross-dress and switch genders if they are to escape prosecution—a humorous move that allows Heyer to explore the manners and language affectations of the period as the two romp through the elite saloons and clubs of London. But what the two don't foresee is that they might fall in love along the way: Prudence with the elegant and dashing Sir Anthony Fanshawe, and Robin with the charming Letitia Grayson. Can the two unmask themselves without losing their lives?
