It was vital to treat the oral testimonies we gathered with an element of scepticism. But these dilemmas were faced by people who were like us in many fundamental ways, and I believe we can thus learn more about ourselves by asking a simple question: “What would we have done?” Certainly, circumstances were different from today. The experiences demonstrate that the past is not some alien world. I was struck by how relevant the testimonies are today. So in 2007 I wrote a book, Their Darkest Hour, about the 35 most extraordinary people I met on my travels. I used some of this material in a number of TV series that I wrote and produced (including Nazis: a Warning from History in 1997 and Auschwitz: the Nazis and the Final Solution in 2005), but a great deal of material has never been published. Auschwitz: the men behind the mass murder.
