On the day of convicted serial killer-rapist John Mathers's execution, a new case following his MO causes a stay after countering the already administered lethal injection and urgent forensic (re-)examination. It was Catherine's first case leading to death row. The most modern techniques, even requiring federal equipment not available to Greg, show another killer was at work and probably one was a copy-cat, but the question remains in which order, as that may or not discharge Mathers.

[All trivia items for this title are spoilers.
When anyone (man or woman) is to be executed, the prison warden is in constant contact with the Governers office and State Supreme Court. This is to make sure that if there are any grounds for the execution not to proceed, it is stopped before the death sentence is carried out. In almost all cases, any halt is called hours if not days before an execution is to happen. A halt has never been called at the last second. See more
