To betray, you must first belong ...

In June 1934, Kim Philby met his Soviet handler, the spy Arnold Deutsch. The woman who introduced them was called 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 beautifully tense novel--by the granddaughter of Kim Philby--tells the story of the woman behind the Third Man.
