Heymann, bestselling biographer of Jacqueline Kennedy Onassis and Barbara Hutton, offers a captivating chronicle of the female power behind American politics in the latter half of the 20th century. In a time when men wrote the rules of the political game, he writes, five formidable women greatly influenced who won and who lost: Washington Post publisher Katharine Graham; Lorraine Cooper, wife of Kentucky's Sen. John Sherman Cooper; Evangeline Bruce, wife of U.S. ambassador David Bruce; Democratic Party fund-raiser (and later ambassador) Pamela Harriman, married to the powerful and wealthy Averell Harriman; and Sally Quinn, Washington Post writer and wife of the Post's former executive editor Ben Bradlee. While they had husbands in high places, these women wielded a vital political influence in Georgetown by organizing the parties where momentous meetings took place and decisions were made. These women were so compelling not only for their professional and political accomplishments and legendary dinner parties but for their dynamic, and often clashing, personalities and ambitions. Heymann deftly explores these personalities through interviews with family, friends, enemies, admirers and detractors. The resulting anecdotal social history of Georgetown is a winning combination of sex, scandal and political escapade. It also provides a complex portrait of its subjects. "What the Georgetown Five ultimately share is their ability to maintain a public pose, to protect the image they sought to create, no matter what the cost, no matter what the burden," writes Heymann, whose earlier books have become award-winning TV miniseries. 16 pages of b&w photos not seen by PW.
