According to this website:
Nancy Wake was the Allies’ most decorated servicewoman of WWII, and the Gestapo’s most-wanted person. They code-named her ‘The White Mouse’ because of her ability to elude capture. When war broke out she was a young woman married to a wealthy Frenchman living a life of luxury in cosmopolitan Marseilles. She became a saboteur, organiser and Resistance fighter who led an army of 7,000 Maquis troops in guerrilla warfare to sabotage the Nazis. Her story is one of daring, courage and optimism in the face of impossible odds.

The other by Russell Braddon.
