Octopus of Crime

Published in the 09/1934 issue of Secret Agent X.
"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."
