What happens to your life when everything you thought you knew about your mother turns out to be an elaborate lie? Ruth Gilmartin discovers the strange and haunting truth about her mother, Sally, during the long hot summer of 1976. For Sally Gilmartin is not what she seems at all. Russian by birth, she was recruited into the British Secret Service in Paris in 1939 and spent the war years as a spy. But once a spy, always a spy. Sally Gilmartin has far too many dangerous secrets, and she has no one to trust. Before it is too late, she must confront the demons of her past. This time though she can't do it alone, she needs Ruth's help. "Restless" is yet another tour de force from William Boyd. Exploring the devastating consequences of duplicity and betrayal, it is a thrilling novel that captures the drama of the Second World War and a remarkable portrait of a female spy. Full of suspense, emotion and history, this is storytelling at its very finest.
