A Tros of Samothrace novelette
From Canada had come the false feint at America’s great steel-armored line that warned Operator #5 that to save his country from the most astounding invasion in history, he and his picked aides must cross the sea to fight a desperate undercover battle with the three bandit nations of the Old World!
Operator #5 starts his grim march through Purple Empire territory to bring guns and ammunitions to our crumbling defenses in the West!
An entire country transfixed–drawn by an intoxicating power to hurl themselves toward destruction. Beneath the Earth, in flaming furnaces of mystical power, lay Operator 5’s future. Will he risk his life–let alone betray the orders of the United States Intelligence Service–in order to dilute this devilish cult of death? Can Jimmy Christopher, with the aid of his loyal pal, Tim Donovan, defy temptation and meet this leprous annihilation head on?
Steele’s Operator 5 adventure has the entire Agency hypnotized–held in the grips of Zaavian cultists. Against Z-7’s orders, Jimmy Christopher will risk dying for his country. Can this spell be broken through this journey into the Cavern of the Damned?
In a naval escapade spanning coastal California to the Panama Canal, Operator 5 tackles a most cunning adversary–Chief secret agent of the Yellow Empire, Kara Vizna, the most dangerous, and most beautiful, secret agent alive.
The Asian Pacific Empire has demanded the surrender of the U.S. Pacific Fleets. Strike first and declare war afterward is their devilish strategy–counterfeiting American vessels to make it seem that the U.S. has instigated the attacks. Only Jimmy Christopher, known in the Intelligence department as Operator 5, has the wherewithal to defeat this devious reign of terror.
