Hamiltons partner and best friend, Lundwall, is murdered by the Mob. Hamilton is dragged into a bitter and brutal vendetta between himself and the Mob-leader Don Tommaso.
Someone is killing off Swedish military officers and making it look like the works of Soviet agents. Hamilton has to crack the case before all hell breaks loose and there is a full scale spy-war with the soviets.
