The police are called in to investigate when a local judge is the target of a series of mysterious attacks, but the case takes a sinister turn when the prime suspect is found dead on his own doorstep. Peggy is delighted when David's new radio starts picking up police broadcasts, but a news reporter does not share her enthusiasm.
