Burns Bannion is back on another assignment: the fleshpots of YOSHIWARA—the age-old home of prostitution in the middle of Tokyo. . .

The young and voluptuous Hiroko puts Bannion on the tracks of her older sister, who has been savagely beaten to death by Bannion's own weapon—

KARATE, the deadly method of Japanese fighting in which the human hand can be as lethal as a knife blade. Before he's finished in YOSHIWARA, Bannion has more corpses lying around than you'd care to count. . .
