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.
