Wire in the Blood - Season 4

When Tony responds to a violent incident at a mental hospital, he believes the inmate was triggered by news of a prostitute's brutal murder. With more victims and no leads, DC Paula McIntyre volunteers to go undercover in a sting operation.

After talking a suicidal man off a roof, Tony assists Alex in evaluating what appears to be a bizarre double murder. Further deaths suggest that the killers might commit suicide after the crime, and Tony believes a secret society may be involved.

Tony gives expert testimony at a parole board hearing, but the police release convicted rapist Jason Eglee against his advice. When a young woman is abducted from a nightclub and murdered, Tony immediately suspects Eglee, despite his rock-solid alibi.
