The Insidious Dr. Fu-Manchu is the first title in the famous series of "Yellow Peril" novels published by English writer Sax Rohmer, aka Henry Sarsfield Ward (1883-1959), between 1913 and 1959. The novel, like its many sequels, pits the "evil genius" of the Far East against the British Duo, Denis Nayland Smith and his sidekick Dr. Petrie.
