DI Monica Kennedy

Sixteen-year-old Robert arrives home late. Without a word to his dad, he goes up to his bedroom. Robert is never seen alive again. A body is soon found on the coast of the Scottish Highlands. Detective Inspector Monica Kennedy stands by the victim in this starkly beautiful and remote landscape. Instinct tells her the case won’t begin and end with this one death. Meanwhile, Inverness-based social worker Michael Bach is worried about one of his clients whose last correspondence was a single ambiguous text message; Nichol Morgan has been missing for seven days....

Annabelle has come to the Scottish Highlands to escape. But as she speeds along a deserted mountain road, she is suddenly forced to swerve. The next thing she remembers is waking up in a dark, damp room. A voice from the corner of the room says, ‘The doctor will be here soon.' Scott is camping alone in the Scottish woodlands when he hears a scream. He starts to run in fear of his life. Scott is never seen again. 

Twelve years ago, DI Monica Kennedy caught the notorious serial killer Pauline Tosh, imprisoning her for life. When Tosh asks Monica to visit her at the remote Highlands Carselang prison, the detective thinks she's playing games. But then Tosh hands her a hand-drawn map with a cross marking the desolate marsh lands near Inverness and Monica can't ignore it—she was always convinced there were more victims out there. And when a body is discovered, it looks like they've found a new name from Tosh's kill list. But things are never that simple.
