Krzysztof Kosior was thirty when he first felt ready to visit Auschwitz. But since childhood, he had heard stories of his great-grandfather’s time there, and of his journey from unknown soldier to one of Poland’s greatest heroes. Talking to actor and spy novelist Charlie Higson, Krzysztof reflects on his family’s memories of Witold, and on the surprising struggles of those with the Pilecki name. Plus he takes listeners inside what happened when Witold met Tomasz Serafinski, whose identity he used during his time in the camp.
