The New York Times bestseller: the incredible untold story of Virginia Hall, an American woman with a wooden leg who infiltrated Occupied France for the SOE and became the Gestapo's most wanted Allied spy, written by acclaimed biographer Sonia Purnell.

In September 1941, a young American woman strides up the steps of a hotel in Lyon, Vichy France. Her papers say she is a journalist. Her wooden leg is disguised by a determined gait and a distracting beauty. She is there to spark the resistance.

The first woman to go undercover for British SOE, her intelligence changed the course of the war - but her fight was still not over. .

This is a spy history like no other, telling the story of the hunting accident that disabled her, the discrimination she fought and the secret life that helped her triumph over shocking adversity.
