Nancy became a valuable courier for a Toulon based Resistance unit, got at least one British operative out of a concentration camp, allowed her home to be used as a safe house, found a five million franc bounty on her head, and after multiple attempts reached Spain from whence she traveled to England. Working throughout Europe, Nancy developed an antipathy to the Nazis from her observations in Vienna during the mid 1930s married to a Frenchman named Henri Fiocca, she offered her services to the Allies and was initially tasked with maintaining an escape route for French aviators attempting to get into Spain. Born Nancy Grace Augusta Wake, she was raised in Sydney, Australia, ran away from home at 16, and made her way to England via New York, supporting herself as a self educated freelance journalist.

Her medals are on display at the Australian War Memorial Museum in Canberra.

Nancy returned home in 1949 and twice stood unsuccessfully for the Australian Parliament before once again going back to England in 1951. She also found that her husband had been killed and that she was essentially broke and thus was forced to remain in the Intelligence Service working at the embassies in Paris and Prague she came to hate the Communists as badly as she had the Nazis.
