Cavern Of The Damned


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?


The Yellow Scourge


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.
