England 1803: Elliot Malvern, seventh Marquis of Ullenwood is very content with his bachelor lifestyle, spending his fortune on the pleasurable pursuits of gambling and mistresses. Rosamond Beaumarsh is determined to remain unmarried and independent. What, then, could persuade them to plunge together into an adventure that carries them to post-revolutionary Paris, and into a headlong flight across France? Only the exercise of logic. The pair embark upon a romantic adventure and learn that rational thought has very little to do with true love.
