Palace of Justice, Nuremberg, 20th November 1945

I always wanted to know exactly how my father had managed to escape from Nazi-occupied Poland and survive the Holocaust that killed almost his entire family.

Like so many other refugees trying to build a new life in a foreign land, he didn’t want to talk about the past he’d lost for ever. When my father reached his early seventies, though, he seemed more willing to open up. Thinking he’d find it easier to talk to a stranger, I arranged for a fellow journalist to interview him.

But there are two things that make the family story of the lawyer and author Philippe Sands stand out from the rest of the genre. First, his assiduous research has enabled him to construct entire chapters of East West Street: On the Origins of Genocide and Crimes Against Humanity from a flimsy scrap of paper or an unidentified photograph. Those interspersed passages, which…
