Hardcover. NY, Doubleday, 1st, 1976, Book: Very Good, Dust Jacket: Very Good, Hardcover in a bright dust jacket. A Scotland Yard procedural with the New York Mafia moving in on a pair of psychotic London supercriminals, the Magnus cousins, modeled on the infamous real-life Kray twins, Ronnie and Reggie. The lead is Detective Inspector Derek Torry, a lapsed Catholic whose fiancee dumps him because of his guilts (he hasn't bedded her once in their two-year engagement). Soon Torry is making it with Jenny, a suspect in a triple bomb-murder, whose former boyfriend was arrested at Dover for smuggling 150 pounds of heroin into the country in his Bentley (she tipped the coppers). Vendettas explode left and right. Clean copy.
