This episode is in the last season of Cannon in 1975. Its one of the best episodes. Tina Louise (Ginger, Gilligan's Island) plays an undercover vice detective investigating a guy murdering hookers. Her mentor in the police academy was Cannon and they hook up again on this case. A judge wears a wig at night and kills hookers while playing this creepy wedding march music. Fantastic script, wonderful acting and lots of plot turns. Nothing this good on TV today.
