SHE NEVER CONFESSED. NOW SHE'S READY TO TALK.

Twelve years ago DI Monica Kennedy caught the notorious serial killer Pauline Tosh, imprisoning her for life.

When Pauline asks Monica to visit her at the remote Highlands Carselang prison, the detective thinks she's playing games.

But then Pauline 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 Pauline's kill list.
But things are never that simple...
An atmospheric thriller set in the Scottish Highlands, perfect for fans of James Oswald, Ann Cleeves and Val McDermid.
