Faced with a rapidly escalating body count, the local sheriff, Captain Peters, holds a town meeting at which the laboratory's leading sex researcher, Henry Murger, urges the town populace to practice sexual abstinence – an idea greeted with derision by the locals. Neil and Julie arrange a meeting with Murger afterwards to discuss his theories as to the cause of his deaths, only to see him chased down and run over by a car with an unseen driver. While investigating Murger's home in search of clues, Neil discovers a secret room concealing sexual paraphernalia and Murger's gay lover, Joe, who informs Neil that he saw Murger driving off with an unknown woman prior to his death.
