A serial killer has gone international. A desperate detective is the only one who can stop them.
Detective Lomac thought his cold cases would remain just that-cold. But when a pattern emerges linking a series of unsolved Oslo murders to a fresh crime scene in Glasgow, he knows he's dealing with a predator who has finally come out of hiding.
Dispatched to Scotland to consult on the case, Lomac finds himself an outsider in a city that doesn't trust him-and a hunter in a game he doesn't fully understand. With no leads, mounting pressure from two police forces, and a killer who is always one murder ahead, Lomac must connect the threads of an old conspiracy.
