My favorite part of this flick is the gotcha end, because that's when Columbo tells an overconfident lady lawyer killer exactly what she was: just that! Which also set the trap for herself. She's so arrogant to believe money can buy anything. Even the love of her dead victim's daughter, who got the pleasure of saying goodbye to a murderous stepmom one last time before Lt Columbo does likewise in another way that brought a big surprise for his target.
