Cold Death - Taking a well-earned break from the 'Dearne Valley Demon' case, Detective Sergeant Hunter Kerr's rest is suddenly shattered when he witnesses a violent argument involving his father, shortly followed by a murderous road-rage attack upon his parents. As he delves deeper, Hunter uncovers disturbing facts and suspects that his father is harbouring a sinister secret from his past; a secret, which he is desperate to keep buried. In his father's native Scotland a sadistic and violent killer is on the rampage. Three retired detectives are found tortured and butchered. Is there a link? Or, is it someone who just likes killing cops? Hunter pushes and pushes to learn the truth, never realising just how much danger he was placing himself, and those around him, in.
