Crooked Cross begins in December 1932, and ends at midsummer the following year. The setting is the little, fictional Bavarian town of Kranach, a picture-postcard place in the foothills of the Alps. Its focus is the Kluger family – a modest, middle-class clan of kindly, loving parents and three grown-up children, Helmy, Lexa and Erich – who are gathering to celebrate Christmas with their cousins and Lexa’s fiance, Moritz. Everything is warm and delightful and full of promise: the tree with its glass baubles and candles, the tissue-wrapped presents, the carols, the roasted goose. Everything is gorgeously decorated, “even” – one reads with a shudder that is deepened by a 21st-century knowledge of where “it” was all headed – “Helmy’s picture of Hitler which stood on the piano”.
