4. Best Defense

The detectives follow the trail when an assistant district attorney confronts and kills a hired gunman following a series of death threats. They first suspect his wife, a prominent defense attorney, through a convict whose case was being prosecuted by the A.D.A. and the rumors of her romantic affairs. When they realise that there are cracks in their seemingly airtight case, Goren has to keep Carver in the dark about some details to prove his theory.
