Hermann Göring has gone down in history as one of the world's absolute worst war criminals. Less well known is his marriage to the Swedish noblewoman Carin von Kantzow and his close relationship with her relatives. Leif GW Persson tells the story of a Swedish family that sits on the front row when German Nazism grows in the 1920s, when it takes over Germany in the 1930s and drives the world to disaster in the 1940s.
