Hopefully, “Rest in Peace, Mrs. Columbo” will put lie to the “There is no Mrs. Columbo” conspiracy theories out there. Because, in this one, someone actually tries to take out the Lieutenant’s wife! Helen Shaver plays Vivian DiMitri, a crooked real estate agent whose husband was sent to the pen by Columbo a few years ago. The guy died in the joint, so she kills her boss (who may have ratted the husband out), mostly to bring Columbo into the case. Her grand plan to take down Columbo? Find his wife’s favorite type of toast spread, apparently. Illustrator Stevie VanBronkhorst (@spoolses)is here to help Jon and RJ make some sense of all of this. Also, we all learn a bit about the wonderful town of Warrenton, Virginia.
