The Tempest twins, Louisa and Lavinia, have been invited to London. When their carriage pulls up to Lord Charleton's Mayfair address, Louisa's heinous cat, Hannibal, gets loose and dashes into the house next door. Louisa unwittingly follows her beloved pet into the bachelor residence of the notorious Mayfair beast, The Right Honorable Pierson Viscount Wakefield. Wakefield isn't amused at finding yet another marriage mad miss in his house. And while she should be furious at the viscount's rudeness, Louisa can't stop thinking about his dusty, horrible house-and that perhaps he wouldn't be such a beast if it was cleaned and well-organized. She can't shake that ingrained belief that she wouldn't be a good neighbour if she left Pierson's situation unmended. Against his wishes, Louisa slowly wrestles Pierson's house into order. Pierson eventually berates Louisa for her efforts and demands she leave him be. Not long after, Pierson realizes that he cannot live without Louisa. Just as they begin to fall in love, though, Pierson's former betrothed returns and aims to sink her claws back into Pierson. Will her selfish manipulations come between them - or will a good neighbour and a clean house bring a happily ever after to the viscount who lived down the lane?
