What becomes of your life when everything you thought was solid and certain about it turns out to be a fantastically complicated lie? This happens to Ruth Gilmartin when, one day in 1976, her mother Sally suddenly tells her she has been living a double life. She is not respectable Sally Gilmartin but in fact Eva Delectorskaya, a spy for the British Secret Service who has been on the run for 30 years.
