Fu-Manchu - The Shadow of Fu-Manchu

World War II has ended. The United States is locked in a Cold War with the Eastern Bloc. It’s the time of mutually assured destruction, yet the atomic bomb isn’t the only weapon to fear. And the Soviets have another enemy with whom to contend.
Dr. Morris Craig has developed an energy weapon with the potential for unlimited destruction—whoever controls it could tip the balance of global power. The quest for Craig’s invention once again brings Fu-Manchu to New York City, his mission to prevent the Communists from acquiring the device. But who can keep it out of the hands of the Devil Doctor himself?

Sax Rohmer was the acclaimed author of the Fu Manchu series of novels. The first, The Mystery of Fu Manchu, was published in 1912 with many more following. Rohmer also wrote more traditional detective stories and supernatural horror. He died in London in 1959.
