Marianne Simpson has the appearance and manners of a sophisticated lady, but every evening she enters the arena of her uncle's traveling circus, and so far no rival has managed to defeat the girl in a fair boxing match.The handsome, noble and arrogant St. John Powell, Duke of Staunton, earned his detractors the nickname Lord Faultlessness. The Duke despises circus performers and comedians, but he needs Marianne, because the girl is the only one who can help him snatch his younger brother from the hands of the cruel and treacherous Baron Strickland.
