The strength of Lee’s book is the way these facts of history are twinned with the perverted domesticity of everyday Nazism. SS men, for example, were encouraged to push prams and change nappies. Before he married, Griesinger’s fiancée, like all SS wives, was subjected to extensive gynaecological examinations, including checks on her menstruation, to be sure that she would produce the minimum four Aryan children. It is the domestic focus that Griesinger’s children say they remember. They claim they knew nothing of their father’s SS membership, and recall only the family Christmases and his care for the family dog. The armchair stuffed with hidden swastikas is an apt symbol for that weird and disturbing double life.
