Fearful Lightning Taggart : Season 16 Episode 3

A string of people are murdered by electrocution. All of these people are in some way connected to with a local (and popular) spiritualist, who claims he can speak with the dead. When the Taggart team disbelieve the man's powers, the clairvoyant gives them frighteningly accurate messages from a man very dear to their hearts--Jim Taggart! Meanwhile, the murders begin to pile up, and Taggart team race to find the murderer, this time aided by Jim Taggart himself.
