Quisling
The word "Quisling" has been used as a synonym for "traitor" or "treachery." The original Vidkun Quisling (1887-1945) was a gifted Norwegian army officer who sided with the Nazis on the first day of Norway's entry into the Second World War. Dahl's biography is the first to use a complete range of source material from Nordic, German, Italian and Russian archives, and family archives now in the United States tracing Quisling's career through to the drama of his trial and execution for high treason in 1945.
