The League of War-Monsters — Frederick C. Davis

A group of bitter men-a secret League of War-was ready to plunge the world into a new, earth-wide conflict. They issued orders, and bloody organized murder was loosed in the heart of Europe! And behind this carnage, a single man was scheming to make himself the Dictator of the World! Never before had a single person conceived such a colossal plan for profiting from the slaughter of humans. He had overcome all obstacles-except one lone avenger, Operator 5, America's secret service ace. Can Jimmy Christopher keep the nations of the world from hurling themselves into a war which can bring nothing but universal defeat, misery, and slavery?
