The lady is a spy: Virginia Hall, World War II's most dangerous secret

Virginia Hall never thought she'd be a spy. The young American had been working for the State Department overseas when she was involved in an accident that required her left leg to be amputated.

Despite this setback, Hall was eager to do something to help the Allies win World War II.

She made her way to Vichy, France where she helped coordinate underground resistance movements, sabotaging the Nazis at every turn.

Her covert operations, including capturing 500 Germans, greatly contributed to the Allies' eventual win.

In 'The Lady is a Spy', author Don Mitchell explores the fascinating life of America's greatest female spy.
