Role of Female Spies in World War II [PDF ebook] 

Although spying has always been a part of warfare, espionage didn’t become an official part of American war efforts until World War II. The United States government established the Office of Strategic Services, which employed spies, translators, map readers, and code breakers to help gather information. Many of these roles were filled by women. This compelling book tells the riveting stories of six of these lady spies, including singer Josephine Baker, who smuggled military secrets on her sheet music; model and countess Aline Griffith; and the dangerously effective "Limping Lady, " Virginia Hall.
