Margaret Mitchell (1900-1949), author of Gone With the Wind , jilted her kind, protective suitor, John Marsh, and instead married Red Upshaw, an unstable bootlegger who physically abused her. Even after she divorced Upshaw, Mitchell, according to Walker, was a confused romantic who in many ways resembled her heroine, Scarlett O'Hara. A "classic demanding-dependent personality," Mitchell found more than a supportive fatherly mate in public relations executive Marsh, whom she finally married in 1925. Walker, a professor of English and philosophy at the University of Kentucky-Henderson Community College, reveals that Marsh played a vital role in the creation of Mitchell's classic Civil War saga. He offered key ideas and advice, continuously edited the manuscript as his wife wrote it, and helped with the revision. Walker quotes liberally from the couple's letters and also draws on interviews, family papers and archival research to tell a moving love story of a symbiotic union that lasted 24 years. A remarkable piece of detective work.
