A powerful army of invasion - armed with the most ghastly modern weapons: bacteria, plagues, hideous diseases - lay carefully hidden within the borders of the United States, ready to strike at the heart of the nation, to kill, pillage, demolish.... A foreign demagogue, mad-drunk with power, greed, and lust, planned the slaughter of a million helpless men and women, to state his twisted, race-proud ambition. Belligerent nations watched and waited, sighting America helpless before them. One man - Operator #5 - read the crimson writing on the wall - and he alone was left to battle the frightful odds!
From from Operator #5 magazine steps a dramatic hero who pits himself against threats to national security from all origins. Whether it's a subversive internal threat, or a full-scale invasion from an enemy land, James Christopher stood ready and resolute to defeat it.
James Christopher did not technically belong to the US Secret Service. He was a top agent for an America's unnamed Intelligence Service. It was in his blood. His father, John Christopher, retired from the same agency years before. Answerable only to his superior, Z-7, and carrying a letter from the President of the United States identifying him as Operator #5, Jimmy Christopher played for keeps. He carried a rapier sewn into his belt, and in a golden skull hanging from his watch-chain was a reservoir of poison to be taken in the event of capture.
Aided by a small group of trusted assistants, ranging from his twin sister Nan to scrappy street urchin Tim Donovan, Jimmy Christopher was a one-man defense force. Proud and patriotic, expert marksman and swordsman, he is the best America has to offer in a time of severe trial.
Invasion of the Dark Legion is read with stirring intensity by Milton Bagby. Originally published in the October, 1934 issue of Operator #5 magazine.
