Wife. Mother. Spy. A double life is no life at all. Since the disappearance of her husband in 1951, Laura Leverett has been living in limbo with her daughter in Geneva. All others see is her conventional, charming exterior; nobody guesses the secret she is carrying. Her double life began years ago, when she stepped on to the boat which carried her across the Atlantic in 1939. Eager to learn, and eager to love, she found herself suddenly inspired by a young Communist woman she met on the boat. In London she begins to move between two different worlds - from the urbane society of her cousins and their upper class friends, to the anger of those who want to forge a new society.
