YMMV / Monk S4E7 "Mr. Monk Goes to a Wedding"

• Complete Monster: Theresa Scott is a Black Widow murderer trying to marry into Natalie Teeger's family via her brother Jonathan. In truth, Theresa has a habit of marrying wealthy men, murdering them, and vanishing, with at least three prior victims. When a photographer remembers her from a previous wedding and tries to blackmail her, Theresa knocks him over the head and leaves him to drown in a mud bath before trying to kill a police officer who worked a previous husband's case. Finally caught, she tries to hold a knife to Jonathan's throat to make good on her escape.
