Secret Agent X #7: Octopus of Crime

His true face unknown, his identity forever buried in a secret government file, Secret Agent ¿X¿ came back from the dead to take on the sinister sadists and evil extortionists who prey on innocent Americans. A master of disguise who carries a non-lethal gas gun, ¿X¿ the unknown is backed by a cabal of wealthy citizens and is answerable only to the shadowy K-9 in Washington. Tentacles of terror reached over the country, spreading like a hideous blight through the cities of America. The Underworld, welded together under the secret symbol of a monster of crime, was organized as never before. And Secret Agent ¿X,¿ master man-hunter, went up against a genius of crime who stooped even to the ghastly horrors of medieval torture.
