On 7 November 1938, 17-year old Polish Jew Herschel Grynszpan shot a Nazi official dead at the German embassy in Paris. The repercussions triggered a calamity which has been called the opening act of the Holocaust. In the novel Champion, Grynszpan's life is intertwined with that of German boxer, Max Schmeling, a poster boy of the Nazis. Rob Weinberg talks to author Stephen Deutsch about Champion, a gripping tale of two lives, which reaches a climax during Kristalnacht.
