He hung up his coat and decided he could lose the suit jacket, too. Some of his colleagues at HQ reckoned the braces were an affectation, but he’d lost the best part of a stone and didn’t like belts. The braces weren’t the shouty kind – dark blue against a plain light-blue shirt. His tie today was a deep dark red. He draped his jacket over the back of his chair, smoothed it at the shoulders and sat down, sliding the locks of the briefcase open, easing out the paperwork on Glen Heaton. Heaton was the reason the Complaints had summoned up the brief round of applause. Heaton was a result. It had taken Fox and his team the best part of a year to compile their case. That case had now been accepted by the Procurator Fiscal’s office, and Heaton, having been cautioned and interviewed, would go to trial.

Glen Heaton – fifteen years on the force, eleven of them in CID. And for most of those eleven, he’d been bending the rules to his own advantage. But he’d stepped too far over the line, leaking information not only to his pals in the media but to the criminals themselves. And that had brought him once more to the attention of the Complaints.

Complaints and Conduct, to give the office its full title. They were the cops who investigated other cops. They were the ‘Soft Shoe Brigade’, the ‘Rubber Heels’. Within Complaints and Conduct was another smaller grouping – the Professional Standards Unit. While Complaints and Conduct worked the meat-and-potatoes stuff – grievances about patrol cars parked in disabled bays or cop neighbours who played their music too loud – the PSU was sometimes referred to as the Dark Side. They sniffed out racism and corruption.
