Skinner's Ordeal

A plane explodes mid-flight and plunges from the Scottish skies, the British and American Defence Secretaries among the victims. For Edinburgh Deputy Chief Constable Bob Skinners, the means of destruction is apparent from the start, but the investigation quickly grows more puzzling as a violence act wenches Skinner out of the picture. As Skinner's ordeal reaches its crescend, the police pursue their suspects one by one, until at last they are brought to a dramatic, thrilling, but tragic conclusion.  Book 5 of series.
