Troublemaker tells the wild and unlikely story of Jessica Mitford, fifth of the six famous Mitford Girls, a British aristocrat-turned-American Communist, famous for exposés like The American Way of Death; this biography brings her astonishing self-transformation to life with a riveting, often hilarious account of trading wealth and status for a life of radical activism. Who could predict that a British aristocrat would so energize American antifascist and civil rights struggles that Time magazine would crown her “Queen of the Muckrakers”? Jessica Mitford, always known as Decca, was brought up by an eccentric English family to marry well and reproduce her wealth and privilege, not to advocate for the rights of others. Her beautiful sisters have been subjects of books and movies dedicated to their naughty, glamorous lives. Decca ran away to America to forge a rebel’s life. As this richly researched book details, Decca broke the Mitford mold. Instead of settling for life as a professional Beauty, she fought fascism in the Spanish Civil War, became an American Communist and pioneered witty, hugely popular journalism, including her 1963 blockbuster The American Way of Death. Decca dedicated her life to social justice and proved herself an immensely effective ally, but she also injected laughter into all her political work, annoying some activists with her relentless antics but encouraging many others to find joy in the struggle. From famed baby doctor Benjamin Spock to best friend Maya Angelou, her anti-authoritarian irreverence had a profound impact on American culture. Mining extensive, untapped sources, and with nearly fifty new interviews, Kaplan’s passionate biography beautifully illuminates how Decca’s hard-won and self-taught social empathy offers a powerful example of female freedom, the dramatic, novelistic story of an extraordinary woman of her time who is remarkably relevant and resonant today.
