When Katrin Himmler, Heinrich's great-niece, was 15, one of her school mates asked during a history lesson if she was related to the Himmler. Yes, she stammered, at which there was a deathly hush in the classroom. The teacher, embarrassed and unsure, quickly moved the lesson on. As she grew older, Katrin gave her family history a wide berth - but married to an Israeli whose family was confined to the Warsaw Ghetto and with a young, half-Jewish son, she realises that she cannot evade the past so easily. Katrin Himmler's cool but meticulous examination of the Himmler story reveals - in all its dark complexity - the gulf between the 'normality' of bourgeois family life and the horrors perpetrated by one member.
