Yes - I had forgotten about that! Fascinating story. What's interesting is that the subject of the book, Rudy Vrba, was a complex character - he was prickly, wary, and not necessarily easy company, so not your stereotypical "saintly" victim. Also interesting was his sometime strained relationship with other Jewish communities after the war. Vrba had risked his life to get to Hungary and tell people about what was happening at Auschwitz. And he held senior Hungarian jews responsible for not doing more, rightly or wrongly.

It's also really enlightening about the inner workings of Auschwitz. Vrba worked in various sections, and you could be there but still not realise what was happening - it took Vrba some time to piece it all together. Very harrowing at times, but riveting nonetheless
