Malcolm Fox

Nobody likes The Complaints - they're the cops who investigate other cops. Complaints and Conduct Department, to give them their full title, but known colloquially as 'the Dark Side', or simply 'The Complaints'. Malcolm Fox works for The Complaints. He's just had a result, and should be feeling good about himself. But he's middle-aged, sour and unwell.

Malcolm Fox and his team are back. They've been sent to Fife to investigate whether fellow cops covered up for a corrupt colleague, Detective Paul Carter. Carter has been found guilty of misconduct with his own uncle, also in the force, having proved to be his nemesis. But what should be a simple job is soon complicated by intimations of conspiracy - and a brutal murder committed with a weapon that should not even exist.
