Set in a brooding, wintry Scotland, McBride’s bone-chilling thriller finds DC Edward Reekie on the trail of a murderer as an ex-cop-turned-gangster is found tortured to death in his bungalow.
It was supposed to be an easy job.
All Detective Constable Edward Reekie had to do was pick up a dying prisoner from HMP Grampian and deliver him somewhere to live out his last few months in peace.
From the outside, Glenfarach looks like a quaint, sleepy, snow-dusted village, nestled deep in the heart of Cairngorms National Park, but things aren't what they seem. The place is thick with security cameras and there's a strict nine o'clock curfew, because Glenfarach is the final sanctuary for people who've served their sentences but can't be safely released into the general population.
Edward's new boss, DI Montgomery-Porter, insists they head back to Aberdeen before the approaching blizzards shut everything down, but when an ex-cop-turned-gangster is discovered tortured to death in his bungalow, someone needs to take charge.
The weather's closing in, tensions are mounting, and time's running out - something nasty has come to Glenfarach, and Edward is standing right in its way.
