The teasing, transparent nighties were so shredded they barely covered the bodies of the murdered beauties. The blonde wore black. The redhead, green. And now someone was combing the city for the same number in white.   Two strange slayings and a very frightened model set Mike Hammer on a chase through the world of high fashion and UN cocktail parties to Village bars and sleazy hotels. Snarling Hammer hits pay dirt when he dives underground to a secret sex cult, and busts open a group of degenerate, but highly eminent kick-killers.   “A breathless mystery of violence, death and the macabre machinations of international operation.”—Savannah News   “A blockbuster finish. Spillane has applied his Midas touch to another thriller.”—Florida Times-Union   “Mike Hammer at his best.”—Charlotte Observer
