That Woman: The Life of Wallis Simpson, Duchess of Windsor by Anne Sebba is the first full-scale biography of Wallis Simpson written by a woman. Wallis Simpson, born Bessie Wallis Warfield in 1896 in Baltimore, was an American divorcee who became notorious for allegedly seducing a British king off his throne. Queen Elizabeth, The Queen Mother, famously referred to her as “that woman.” Despite neither being beautiful nor brilliant, Wallis had an impoverished childhood that fueled her burning desire to rise above her circumstances.
