Klaus Barbie: The Butcher of Lyons (often associated with investigative journalists Tom Bower or Brendan Murphy in different editions) is a biographical account of the life and crimes of Klaus Barbie, a notorious Gestapo lieutenant who directed brutal operations in Lyon, France, during World War II. The book details his actions, his postwar evasion of justice with the help of Western intelligence, and his eventual trial. The book serves as an exposé of both Barbie’s personal brutality and the shocking complicity of Western intelligence services in allowing a major war criminal to evade justice during the Cold War.
