When Pamela Churchill Harriman died in 1997, the obituaries that followed were scathing – and often downright sexist. Written off as a social climber, her glamorous social life and infamous erotic adventures overshadowed her true legacy. Much of what she did behind the scenes to shape the twentieth century, on both sides of the Atlantic, remained invisible. That is, until now: with a wealth of fresh research, Sonia Purnell unveils for the first time the full, spectacular story of how Harriman left an indelible mark on the world today. There is practically no-one in twentieth-century politics, culture and fashion whose lives she did not touch.
