The year is 1539 and the court of Henry VIII is increasingly fearful at the moods of the ageing sick king. With only a baby in the cradle for an heir, Henry has to take another wife and the dangerous prize of the crown of England is won by Anne of Cleves.

She has her own good reasons for agreeing to marry a man old enough to be her father, in a country where to her both language and habits are foreign. Although fascinated by the glamour of her new surroundings, she senses a trap closing around her. Katherine is confident that she can follow in the steps of her cousin Anne Boleyn to dazzle her way to the throne but her kinswoman Jane Boleyn, haunted by the past, knows that Anne’s path led to Tower Green and to an adulterer’s death.
