'Eva Delectorskaya,' I said mystified. ' Who's that?' 'Me,' she said. 'I am Eva Delectorskaya.' What happens to your life when everything you thought you knew about your mother turns out to be an elaborate lie? During the long, hot summer of 1976, Ruth Gilmartin discovers that her very English mother Sally is really Eva Delectorskaya, a Russian emigre and one-time spy. In 1939 Eva is a beautiful twenty-eight year old living in Paris. As war breaks out, she is recruited for the British Secret Service by Lucas Romer, a mysterious, patrician Englishman. Under his tutelage she learns to become the perfect spy, to mask her emotions and trust no one. Even those she loves most. Since then Eva has carefully rebuilt her life - but once a spy, always a spy. And now she must complete one last assignment. This time, though, Eva can't do it alone: she needs her daughter's help. Restless is a tour de force. Exploring the devastating consequences of duplicity and betrayal William Boyd's gripping novel captures the drama of the Second World War and a remarkable portrait of a female spy.
