From The Perry Mason TV Show Book (Revised and Amplified)
Bonnie Craig is accused of dispatching her cousin, an aspiring poet who claims to channel the writing of her late brother, Thomas Leslie Walker, another would-be bard and the subject of a wealthy, vulnerable, grieving mother’s obsession.

Perry comes up with another of his demonstrations—this one involves both ESP and a 22,000-volt contraption known as the Faraday Cage—to defend his client and solve a related mystery.
