I had the 4th season sitting around for a while before I finally watched this Mrs. Columbo episode yesterday.
OK, granted the idea of Mrs. Columbo is kind of silly (the opening credit sequence is almost as siller as another spin-off to another show called K9 and Company, and kudos to anyone who knows that), but I kind of liked the episode on season 3 with Donald Pleasance. This one with the puppet guy was just so lame and seemed more at place in my new season 3 of Tales from the Crypt. Also, the clues (the screwdriver placement and the flower) were so contrived and easy and stolen a certain other Columbo episode, Etude in Black.
