Meet the Duke of Ruisdell, the unlikely hero of this traditional Regency Romance, after the manner of Georgette Heyer and Candice Hern. The duke has just returned wounded from the Napoleonic wars. He is weary, cynical, and very bored. Known as the worst rake in England, he finds he has no interest in upholding that distinction, when his friend, the Marquis of Somerset, proposes a bet: "Five thousand guineas says that seducing Miss Elise Edwards will cure your ennui." Because his friend has just lost a packet to him, he agrees that the bet be posted in White's famous Betting Book. The following day, while walking in Green Park, he spies a mysterious young woman, veiled, and obviously grieving. A disembodied voice, sounding strangely like that of his late adjutant, informs him, "The jig is up. That is the girl you are going to marry!"
