'Unmissable Rankin, as gripping and involving as any Rebus story' CHOICE; 'A brilliant book' GUARDIAN

From the No.1 bestselling author of A SONG FOR THE DARK TIMES

'On the evidence of THE COMPLAINTS it looks as if Fox will be just as sure-footed a guide to the city as his grizzled predecessor' DAILY EXPRESS.

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. He also has a father in a care home and a sister who persists in an abusive relationship.

In the midst of an aggressive Edinburgh winter, the reluctant Fox is given a new task. There's a cop called Jamie Breck, and he's dirty. Problem is, no one can prove it. But as Fox takes on the job, he learns that there's more to Breck than anyone thinks. This knowledge will prove dangerous, especially when murder intervenes.
