 DI Jack Frost is now living above an Indian curry restaurant and his day is off to an inauspicious start when he is held by a gun-toting teenager suspected of dealing in drugs. The police are concerned that there may be others guns being sold on the street. He also has to deal with another armed robbery of a security van and the death of a part-time soldier on maneuvers who was shot when everyone was supposed to be using blanks. Frost suspects the van robberies are an inside job. It s determined that the soldier could not have been shot with a military weapon and the police find an identical pistol to that used by the gun-toting teenager. Frost soon determines the motive and the identity of the killer.
