Not since the sinister Dr. Fu Manchu himself has there been a more fascinating villain than Yu'an Hee See, who moves like a dark cloud of evil through the breathless pages of this new book of mystery and adventure. Limehouse, Marseilles, the near East, the placid Mediterranean are the scenes of his murderous battle with Dawson Haigh of Scotland Yard, with the beautiful girl Haig loves as a pawn and a vast fortune of gold as the stake. This is Sax Rohmer's most exciting book since "The Hand of Fu Manchu."
