Ruth Gordon is mystery novelist and playwright Abigail Mitchell, in season seven’s “Try and Catch Me.” When Mitchell’s beloved niece dies in a boating incident, she suspects murder. When the police fail to find evidence of foul play, she does the next natural thing- killing the niece’s husband by locking him in a vault. Everyone does that, right? Myke Chilian (Uncle Grandpa, Rick and Morty, Channel 101) joins Jon and RJ to see how Columbo could find such a sweet old lady to be such a cold-blooded killer.
