Secretly, behind closed doors and guarded portals, the mysterious Black Power of Zaava spread its hidden terror throughout America. What evil force was behind the destruction of churches; the wholesale disappearance of entire congregations? What sinister spell had fallen upon American men and women to make them hurl themselves into white-hot flaming furnaces? A trap worse than death is laid for Operator 5 when, in a final effort to combat this monstrous hidden power, he makes his way alone into the Cavern of the Damned!
From out of the pages of 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.
In 1934, with Hitler consolidating power in Germany and the Japanese Empire on the rise in Asia, young pulp publisher Harry Steeger decided that the American public was ready for a magazine chronicling the exploits of an undercover agent dedicated to defending the United States from foreign aggressors. With his editors, Steeger came up with a title, Secret Service Operator #5, and a cover depicting a masked terrorist fleeing an exploding White House. Over this loomed the resourceful hero, blazing away with a .45 automatic. His job: to defeat a new invasion of the United States—every month!
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.
Into this unprecedented crisis plunged Jimmy Christopher. Only one man, but a man who embodied the American spirit—and stands prepared to perish to protect his country.
From the August, 1934 issue of Operator #5 magazine comes Cavern of the Damned. Read by Milton Bagby with single-minded intensity.
