In June 1934, Kim Philby met his Soviet handler, the spy Arnold Deutsch. The woman who introduced them changed the course of history. Her name was Edith Tudor-Hart. She changed the course of 20th century history. Then she was written out of it. Drawing on the Secret Intelligence Files on Edith Tudor Hart, along with the private archive letters of Kim Philby, this finely worked, evocative and tense novel tells the story of the woman behind the Third Man.
