Marion Crawford was 22 when she became governess to the young princesses Elizabeth and Margaret in 1933. A working-class girl with progressive ideas, she had intended to teach children in the Edinburgh slums. Instead, she had a ringside seat at some of the most seismic events of the 20th century.

The castles and palaces housed a family frozen in time. But outside the royal gates, poverty and unemployment were breeding unrest in 1930s Britain. Hitler was on the rise in Europe. If royalty was to survive, it must draw closer to the people. And so Marion took the princesses on tubes and buses, swimming at public baths, Christmas shopping at Woolworth’s.

Marion’s devotion meant personal sacrifices. Her passionate affair with a socialist ended tragically. The royals refused to let her leave to marry and start a family. But 17 years of dedication counted for nothing once she published The Little Princesses, a loving, harmless account of life as a royal governess. It earned Marion the Windsors’ lasting fury.

Basing her fiction on Marion’s own accounts, plus a wide range of historical sources and her own imagination, Wendy Holden shines a captivating light into the childhood of the world’s longest reigning monarch. This is a story of conflict and contradiction, of state dinners and hunger marches, of a left-winger amongst the ultimate conservatives, of a modern woman in an ancient institution. And the divided Britain of the 1930s: the unemployment, the opportunity gap, the rise of the far right. All of this resonates with our own troubled times.
