After years of dangerous fighting on the Peninsula, Captain Jack Carrington has returned home to take up family duties and find himself a wife. But his life is thrown into turmoil when he views a fencing lesson unlike any other. The talented student is no student at all, but a beautiful young woman, and the most infamous courtesan in all of London—Lady Belle.

Who is the mysterious Belle? A jaded cyprian seeking her next protector? A kind friend helping those in need? Or a mistress of sensual delights that tempt a man to madness? Eager to uncover the true woman behind the facade, Jack wagers he can win a kiss from Belle if he bests her at fencing. And though Belle is a woman he can neither afford to keep nor dare to marry, he’s willing to risk it all to win her to his bed.
