From its dawn in the 1660s to its twilight in the 1960s, Cliveden was an emblem of elite misbehaviour and intrigue. Conceived by the Duke of Buckingham as a retreat for his scandalous affair with Anna-Maria, Countess of Shrewsbury, the house later served as the backdrop for the Profumo Affair, which would bring down a government and change the course of British history.In the three hundred years between the Countess and Christine Keeler, the house was occupied by a dynasty of remarkable women: Elizabeth Villiers, an intellectual who brokered the rise and fall of governments; Augusta of Saxe-Gotha, a minor German royal who almost became queen of England; Harriet Duchess of Sutherland, the glittering society hostess turned political campaigner; and Nancy Astor, the consummate controversialist who became the first woman to take a seat in parliament. Under the direction of these women, Cliveden provided a stage for political plots and artistic premieres, hosted grieving monarchs and republican radicals, was idealised as a family home, and maligned as a threat to national security.The Mistresses of Cliveden is by turns a historical epic, a political thriller, a family drama, and an intimate history of the relationships between people and place. Above all, it is a story about sex and power, and the ways in which exceptional women have evaded, exploited, and confronted the expectations of their times.
