"Jamie McKinnon's mum vanished on a Wednesday afternoon."
How can you save somebody else if you can't save yourself?
When widow and young mother Stephanie McKinnon's disappearance in the Scottish Borders is escalated to the Major Investigations Team, it couldn't have come at a worse time for DCI John Waters. Pulled into a complex case while dealing with his own torment, his inner demons threaten to consume him.
Garry Plumb, meanwhile, is building a life he never thought possible – a thriving company, a fiancée he adores, and a future that almost lets him forget what he is. But the beast inside hasn't gone anywhere. It's just waiting for a reason to come out – and it finds several.
Garry tells himself that each kill is righteous, but there's no escaping that the voice talking him into it doesn't sound like his own conscience. This voice is familiar, and monstrous.
Waters' desperation to reunite the missing mother with her little boy grows and, knowing things nobody else does, he turns to Garry. The only question he needs to answer is: can Garry's past save their future, or has he become the very thing he once destroyed?
