'After what happened, none of us can be sure we're going to see tomorrow'

The killing was an expert hit. Three shots through the head, as the lights dimmed at a celebrity concert in Glasgow. A most public crime, and Edinburgh Chief Constable Bob Skinner is right in the centre of the storm, as it breaks over the Strathclyde force.
The shooters are dead too, killed at the scene. But who sent them?
The crisis finds Skinner, his private life shattered by the shocking end of his marriage, taking a step that he had sworn he never would. Tasked by Scotland's First Minister with the investigation of the outrage, he finds himself quickly uncovering some very murky deeds...The trail leads to London, where national issues compromise the hunt. Skinner has to rattle the bars of the most formidable cage in the country, and go head to head with its leading power brokers . . . a confrontation that seems too much, even for him. Can the Chief solve the most challenging mystery of his career . . . or will failure end it?
