A seventeen-year-old Jewish boy, a poor Polish immigrant in Paris, handsome and gentle, buys a gun, goes to the German embassy in Paris and shoots the first diplomat he meets. The shooter is Herschel Greenspan, the diplomat is Ernst Pom Rath, the year is 1938. The reason for the assassination: Greenspan wants to take revenge on the Germans who are persecuting his family members in Poland. Pom Rat breathed his last two days later. Goebbels and Hitler jump on his death as the finder of great loot. The assassination would be a wonderful excuse to massacre the Jews. It will be the excuse for "Kristallnacht" - "Crystal Night" - which some see as the beginning of the Holocaust. The Gestapo imprisoned Greenspan in order to put him on a show trial. But from then on, a battle of wits began between the young, innocent and inexperienced young man, who starred in the headlines of the world's newspapers, and the senior officials of the Nazi regime. Greenspan has the upper hand. Based on new research, Stephen Koch unfolds the amazing story of the brave young man as a never-ending suspense story.
