This book is a thought-provoking exploration of the trial of Adolf Eichmann, a major organizer of the Holocaust. The author argues that Eichmann was not a fanatical ideologue, but rather an ordinary individual who simply followed orders and bureaucratic procedures, highlighting the terrifying potential for evil in any system that values obedience over personal responsibility.
