Edith Lavery is middle class, the only child of an accountant and a mother with social ambitions. She works in an estate agency and is bored by it. Almost by accident she bags one of the country's most eligible bachelors, Charles, Earl Broughton, heir to the Marquess of Uckfield. He's not especially bright, but is a decent, loyal man. Edith doesn't love him but the opportunity is really too good to pass and they marry. How will Edith cope with her elevation to the aristocracy? More importantly, how will she cope when she realises that she's exchanged one form of boredom for another?
