As Lady Sophia Beresford (recently Lady Finkel) passes through the gates of her new bridegroom's country estate and he begins to whisper in her ear of the delights that await her in his bed, Lady Sophia realizes she has made a most dreadful mistake. There's only one thing to do. She must bolt.
The bride-on-the-run is rescued by the exceedingly handsome William Birmingham who thinks she's a woman named Isadore, and though he's the richest man in England, she mistakes him for a common (but well-to-do) criminal. Since she'd rather be dead than wed to Finkel, Sophia pretends to be Isadore and take her chances with the provocative Mr. Birmingham. But how could she have known that her ruse would bring the gallant Mr. Birmingham into such peril from the wicked man she married? And how could she have known her enigmatic rescuer would ignite passions she'd never known she possessed?
