In the 28 years from 1931 to 1959, Rohmer added a further 10 books to the Fu Manchu series, meaning the series totals 13 books in all (not counting the posthumous short story collection "The Wrath of Fu Manchu and Other Stories"). The Fu Manchu series drew much criticism from the Chinese government and Chinese communities in the U.S. for what was seen as negative ethnic stereotyping. Sociologist Virginia Berridge has stated that Rohmer created a false image of London's Chinese community as crime-ridden, further claiming that the Limehouse Chinese were one of the most law-abiding of London's ethnic minorities. Critic Jack Adrian has written: "Rohmer's own racism was careless and casual, a mere symptom of his times".
