Burroughs Edgar. Carson of Venus

Carson of Venus is the third book in the Venus series (Sometimes called the "Carson Napier of Venus series") by Edgar Rice Burroughs. Burroughs wrote the novel in July and August 1937. It was serialized in 1938 in six weekly installments from January 8 to February 12 in Argosy, the same publication where the previous two Venus novels appeared. It was published in book form a year later from Edgar Rice Burroughs, Inc.
The novel, which was written two years before the outbreak of World War II, satirizes Nazi Germany by including a fascist political faction called the "Zani." There is also a character named "Muso" as a reference to Benito Mussolini. Unlike the first two Venus novels, Carson of Venus focuses on spy intrigue and war instead of wilderness adventuring.
