Who is Dr. Rance Mandarin? A wizard of science dedicated to hurling modern man back into the Stone Age! A twisted combination of Albert Einstein and Boris Karloff. The malevolent monster who calls himself Doctor Death! Master of the Black Arts, invoker of evil elementals and generalissimo of an army of marauding Zombies, Doctor Death has decreed that mankind must revert to a more primitive state-or perish! And standing against him, a scientific detective steeped the ways of the occult-Jimmy Holm, brave leader of the Secret Twelve, a council of business and political leaders whom Death has marked for destruction. Together, they are mankind's last hope of preventing civilization from crumbling under his sinister supernatural spell. One by one, the Twelve begin falling victim to the evil scientist. Is the end of everything near?
