This was for me a highly interesting account of how British communist intellectuals - including the Cambridge spies - were recruited as Soviet agents in the 1930s. It sheds light on the key role played by Melita Norwood in passing over details of the cladding of uranium reactor rods (gained from her duties as secretary at research institute) which enabled the USSR to make an atomic bomb in a much shorter time than predicted by Western experts. In the 1950's I was a pupil at the school where Melita's husband Hilary Norwood was the senior science master - in fact he was my form master. So for me this account had special resonance. I can well understand that this straightforward story about the life of a very ordinary woman may lack the drama of a Le Carre novel and may not have universal appeal. However it was the very fact that Melita Norwood appeared to lead such an ordinary life that made her such a successful spy.
