America, last citadel of freedom and democracy in the world, has made a valiant but futile stand against the ravening war hordes of the cruel conqueror, Rudolph I, the man whose super-fighting machine is ruthlessly putting the nations of civilized man in thrall. Daily mass executions of men and women — even children — on the Eastern seaboard, are but one of the diabolical means of bringing the surviving patriots to heel. But there is one band that will never yield, who grimly say: “Death before dishonor!” Their leader, Jimmy Christopher, known to them as Operator #5, realizes that only one bold, desperate move can furnish his fellow Americans with the thundering fleet of air destroyers with which alone they can hope to save their country. Grimly, quickly, silently, he sets his plan in action!
The Purple Invasion was heady stuff for a pulp magazine. Never before had an action hero failed to resolve the main threat by the end of his own magazine’s lead novel. But in the new Operator #5 magazine, Jimmy Christopher was forced to fight on and on, with no clear victory in sight. In fact, the situation simply got worse and worse with each intense installment. Long-time characters perished. New ones were introduced. They fell in battle. It was heroic tragedy on a scale never before seen.
Thundering across a ravished America comes a loot laden train bearing twenty million dollars in gold, hurtling toward the despoiled metropolis of New York, where Emperor Rudolph I has established headquarters. Suddenly the train trembles to a stop. A desperate little band of American patriots, who refuse to bow to the conqueror’s yoke, make a bold attack. Their leader, Jimmy Christopher, known as Operator #5, realizes that that trainload of gold is the only chance for America to repel the brutal invaders!
