YMMV / Bonanza S 04 E 31

• Complete Monster: William Poole, the so-called "Thunder Man", is a friendly-seeming demolitions expert whose pleasant nature belies a violent Serial Rapist and murderer of women. When a helpless young woman crosses his path in the opening pleading for him to help her stroke-afflicted uncle, Poole uses the opportunity to rape and murder her on the spot. Poole attempts to murder the woman's paralyzed uncle afterward, silently gloating over the man with the knowledge he witnessed every moment of Poole's assault on his niece, and, when another young woman clues in that Poole was the murderer, Poole breaks her neck. Poole is confronted by Joe Cartwright at the end of the episode, who pieces together Poole's list of victims is hardly contained to the current day, to which Poole sneeringly declares himself untouchable by heaven or Earth and attempts to kill Joe with a vial of nitroglycerin.
