Cartoonist Pond (Over Easy, The Customer Is Always Wrong) weaves glimpses of her own life into an entertaining group biography of the notorious, eccentric Mitford sisters—Nancy, Pamela, Diana, Unity, Jessica, and Deborah. Growing up in suburban Southern California in the 1960s, Pond envied girls who had sisters rather than her boorish brothers; she envied, too, the Mitford girls’ rebelliousness, glamour, and sophistication. Born between 1904 and 1920, the sisters spent their childhood isolated on their family’s vast estate, each inhabiting “an island unto themselves.” Politically, they emerged with diametrically different views: Diana and Unity became unabashed fascists. At the age of 22, Diana divorced her husband to carry on an affair with Oswald Moseley, head of the British Union of Fascists, whom she eventually married. Unity, an ardent admirer of Hitler, went to Germany to meet him and soon, to her family’s horror, published a scandalous letter denouncing Jews. Jessica, on the other hand, touted communism and socialism. With Esmond Romilly (a nephew of Winston Churchill), she left home to aid in the Spanish Civil War. Defying her furious parents, they married and moved to the U.S.; she became a widow when Esmond was killed during World War II, and she later married a lawyer who shared in her labor and civil rights activism. Jessica made her name writing exposés, the first being The American Way of Death, skewering the funeral home industry. Nancy was the first to make her mark as an author, writing satirical novels that offended several members of her family. Pond recounts the sisters’ marriages, divorces, affairs, pregnancies, miscarriages, occupations, and preoccupations, all set in the context of the turbulent times in which they lived: “Across the scope of the entire 20th century,” Pond writes, “was the Mitford Circus.”
