***SPOILERS*** By the elevator being "fixed" is what caused the death of supposedly in house psychic Philip Paisley, James Forresst. It was Philip who was shown up by his cousin Bonnie Craig, Sonya Wilde, in a psychic automatic writing demonstration at the home of her Aunt Sylvia Walker, Virginia Fields. Philip who's been using his "psychc powers" to talk to and communicate with the dead has convinced Aunt Sylvia that he can contact her recently deceased son Thomas who incidentally died the same way the Philip did in an elevator accident: or was it an accident! Perry Mason, Raymond Burr, a friend of the family who just happened to be at the scene of the accident and saw Bonnie give her automatic writing demonstration takes up her case in that she's the one suspected by the police in driving a hopelessly drunk, with Bonnie providing him with the booze,Philip to get himself killed by rigging his private elevator to free fall with him inside it!
In trying to prove that Bonnie's supernatural powers of ESP, extrasensory perception, is the real deal to show that she didn't plan to get Philip to kill himself in the first place Perry gets real life ESP expert Dr. Ardrija Puhrich to have her tested for it which she fails with flying colors. Thus making things look bad for both her and her defense lawyer Perry Mason in being accused by the police in freaking Philip out to the point where he fell into the trap, the fixed elevator, that she set for him. As it soon turns out it's really not Bonnie's psychic ability that's in question in the death of Philip Paisley but her knowledge of electronics that she needed to rig the elevator to crash with Philip getting crushed under it. And it was that ability that someone at the scene of the crime had beside Bonnie, who studied electronics in collage, who was the person who not only murdered Philip but his cousin Thomas as well!
***MAJOR SPOILERS*** Shocking electoral demonstration put on by Perry Mason which smoked out the real killer who it was discovered not only had it in for Philip but his cousin Thomas or was the killers original target. In Philip finding out what Thomas did by framing the person in the crimes that he himself committed as well as Philip finding out about it and using that information to blackmail him or her for money and a high position, vice president, in family business!
P.S Doctor Puharich playing himself was really convincing in the scenes that he was in making you for a moment think he was being played by an actor not himself until you saw his name in the closing credits. As for the acting honors in this Perry Mason episode they have to go to James Forrest who played Philip Paisley who's over the top and tooth grinding performance, that lead up to his ultimate death by elevator, rivaled even that of the killer shark in the movie "Jaws".
