A true tale of spying and espionage in the tradition of "Operation Mincemeat" and "Agent ZigZag". It is the story of a communist superspy in the first half of the 20th century; a story that takes us from Bohemian Prague and Weimar Berlin to the Spanish Civil War and World War II. Otto Katz was the inspiration for the character of Lazlo in "Casablanca", and encountered major figures such as Kafka, Marlene Dietrich, the Cambridge Spies, Noel Coward, Hitler and Stalin in the course of his subversive career.
