Caught in a scandal, Betty Galloway, Lady Frimley, agrees to a fake courtship with Nash Chastain, Viscount Longford.

Betty copes with the loss of her husband two years ago by gambling at Sutcliffe's, a notorious gaming hell and pleasure club. She even has a room of her own there where she enjoys the company of any of a number of the young male patrons, no strings attached. She keeps a list in her diary of the men she wants to sleep with. One man who's not on that list is Viscount Longford.

Nash put Betty out of his thoughts when she turned down his proposal six years ago. He's surprised when Betty seduces him at Sutcliffe's, a night of passion that is interrupted by a scheming young woman hoping to trap him into marriage. A pretend engagement to Betty is the perfect answer to avoiding scandal, and the perfect chance to explore that passion.

He's got another chance to show Betty how much he loves her. Can he win her heart this time?
