ROHMER, SAX & HUGH HEFNER. The Insidious Dr. Fu-Manchu. New York: McKinlay, Stone & Mackenzie, 1920. Fifth Edition. Playboy Magazine Founder Hugh Hefner’s copy with his bookplate affixed to the front pastedown and a letter of provenance from the Hugh M. Hefner Foundation. One of the older books in the Hefner Playboy Mansion library and perhaps a favorite book of his youth. The first Fu-Manchu mystery novel. Very good used copy without dust jacket.
