第 1 集 Time to Murder and Create
播出时间：2006年9月21日
When a rapist who was convicted on Tony's evidence is released Tony appears to be discredited. To make matters worse Carol has left for South Africa without even saying goodbye to him. He offers his help to her successor, Alex, another female officer, when a number of young women are found dead, their bodies buried in fields.

When a young prostitute is found dead, clinical psychologist Dr. Tony Hill sees an immediate parallel with the crimes committed by an incarcerated serial killer, Derek Tyler.

When a young woman is raped and murdered after being kidnapped from a nightclub, Tony Hill is convinced that Jason Eglee is responsible. Ten years previously Tony had got him to confess to the rape of Tracy Bradshaw in what was Tony's first case working for the police. Eglee was released on parole, against Tony's advice, only three weeks before the most recent crime. When a crusading journalist questions Tony's interrogation technique and pushes for Eglee's original conviction to be overturned, DNA testing proves the man is innocent. The evidence notwithstanding, Tony...
