Lyon, France, 1943. In an unassuming house in a quiet street, factional leaders of the French Resistance arranged to meet in secret, in a room above a doctor’s surgery. Ten minutes after the meeting had started, the Gestapo stormed the building and rounded up everybody inside. They did not know it immediately, but the Germans had caught the biggest fish of them all: Jean Moulin, the leader of the Resistance. He is eventually given up, and brutally tortured to death. James Holland is on the ground with historian, Clare Mulley, where they follow the trail of Moulin’s activity leading up to his arrest, imprisonment, and ultimate demise. They visit key sites such as the doctor’s house, Mont Luc prison, and the Traboules; a network of secret passageways used by resistors to avoid detection. It is likely more than luck that the Gestapo were able to catch so many resistance leaders in a single swoop.
