Killers have terrorized Aberdeen in the past--Detective Sergeant Logan McRae has the scars to prove it--but when body parts show up in a cargo container at the harbor they kick off Scotland's largest manhunt in twenty years. Last time they were searching for Kenneth Wiseman, a brutal killer who terrified the country, who was eventually caught only to be acquitted eleven years later on a technicality. Now he's gone missing, people are dying, and the police are certain he's at work again.
