The Spy Girls Files - Spy Girls, #1

Before they were mothers and grandmothers, the women of the Greatest Generation were many other things. Including spies. Meet Violet and Claire. Violet, the faithful suburban wife and mother, PTA president and Girl Scout leader. The perfect image of post-war blue-collar domesticity. Claire, the privileged daughter of a diplomat. A spinster, dedicated to bettering the lives of others as a civil servant, a woman in a man's world.
Two women with nothing in common. Until the secrets of their past begin to emerge. These five stories explore the stories that bring Claire and Violet to a fateful meeting-one that might eventually uncover the secret past that connects them.
