Thanks to her noble parents, Lady Anne Glenconner has been friends with the future Queen Elizabeth II and her sister, Princess Margaret since childhood. Throughout her long life, Anne was close to the royal family: she attended the coronation of Elizabeth II and was a lady-in-waiting to Princess Margaret until her death in 2002. Friendship and duties at court were overshadowed by personal tragedies: an unsuccessful marriage with the flighty Baron Glenconner, who left his entire fortune to a servant, the death of two sons and the coma of a third son. All this time, Anne continued to accompany the royal family around the world and develop the Caribbean island of Mustique, which became a favorite haven not only for Princess Margaret, but also for celebrities around the world. "Maid of Honor" is a frank and touching story of female friendship and life in a golden cage, shedding light on the secrets of the royal court.
