When a leading Scottish politician doesn't turn up at work one morning, it seems like a simple missing persons case to Brian Bain. But then a big news story lands and things don't seem to be so clear cut.
Meanwhile, the discovery of a body in Midlothian's Gore Glen leads DI Scott Cullen on a wild chase through nearby Gorebridge and across southern Scotland, while the press close in on Cullen over choices made on a previous case, unearthed during a new mysterious podcast about the police.
Is there a connection between the two cases? Will Cullen be able to catch the killer before they strike again? And will the ghosts of Cullen's past come back to haunt him?
