内容简介：
Ten years ago Pam Thomas witnessed her parents' murders. The events were so terrifying and traumatic, she blocked out all the events of that night. Two weeks ago she began getting threats on her answer phone. Two days ago a dead rat was left on her doorstep with a note saying, she'd be next. Now she's gone missing. Detective Sergeant Katie Mitchell is assigned to take over the case when DCI Martin suffers a heart attack. With the aid of her partner, DI Colin Farnsworth, she must find Pam Thomas before it is too late and she is found dead. The only way to find Pam Thomas is to solve a murder case that happened ten years ago. Katie Mitchell has no crime scene and no evidence to provide any leads because after the murders, the house was burned down. The Thomas murder file has mysteriously disappeared. The prime suspect in the parents' murders was Jamie Thomas, the brother, a man she recently met on holiday and takes a fancy to. Her challenge becomes even more difficult to embrace when her own life becomes threatened. Will she find Pam Thomas in time? Is Pam already dead?
