Tony's first case with the police comes back to haunt him when Jason Eglee, convicted of murder on Tony's evidence, comes up for parole. Jason appears to be a reformed character after years of therapy in prison, but Tony's not convinced and manages to sway the board to his view until Eglee's distraught mother attacks him before collapsing and dying.
For the press and public Tony has blood on his hands and Eglee is released as a compassionate gesture. When a girl is murdered in the same circumstances as Eglee's former victim, Tony is in no doubt that Eglee is starting a new spree. But Eglee has a cast iron alibi and when he is persuaded to give a blood sample for matching to the original crime for which he was imprisoned he is found to be innocent: the crime DNA isn't the same.
Tony's confidence begins to crumble and, as the press hound him for an expose, Alex decides she can no longer permit him to work for the police. However, not everyone has lost faith in Tony and his acuity hasn't deserted him. As the murderer gears up to take another victim, Tony suddenly realises who they are and why.
