From Canada, now prostrate under a tyrant rule, had come the threat that warned Operator #5. The three bandit nations of Europe were planning a monstrous, unprovoked invasion of this country — and he must cross the sea with two hundred volunteer aides in a desperate undercover battle. One by one, the gallant members of that doomed company of patriots died, willing sacrifices on the altar of patriotism, buried in foreign fields. Finally, having matched the enemy’s secret agents, man for man, Operator #5 alone was left to confront that mighty, mechanized army, already landed and ravaging freedom’s sacred shores!
For his first effort, The Masked Invasion, Operator #5 author Frederick C. Davis selected a super-scientific menace, but he soon began pitting James Christopher—Operator #5 of the United States Intelligence Service—against the Yellow Empire, thinly-disguised European dictators, and other torn-from-the-headlines global actors. The more Operator #5 exploits Davis and subsequent writers wrote, the more horrific the threats to national security became: Wicked would-be conquerors, creepy cults, weird famine-creating menaces to our mid-western breadbasket. Davis’ tales were disciplined, yet apocalyptic—a difficult accomplishment when you are tasked to turn out a 50,000-word novel every 30 days! And all this would lead to the epic Pulp Classic - The Purple Invasion.
Investigating a strange attack from friendly but helpless Canada, Operator 5 learned that to save his country from the most astounding invasion in history, he and his volunteer aides must cross the sea to fight a desperate undercover battle with the three bandit nations of the Old World — and match American agents against their foes in the grim hope that he might overwhelm a ruthless enemy!
