It was supposed to be an easy job. All Detective Constable Edward Reekie had to do was pick up a dying prisoner and deliver him somewhere to live out his last few months in peace. Glenfarach looks like a quaint, sleepy, snow-dusted village, 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 Victoria 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.
