I suppose that calling this a favorite episode isn't saying much since I didn't consider any of the "Mrs. Columbo" episodes to be well written. Nevertheless, and in spite of some negative reviews, this was one of the few that I enjoyed. It had nothing to do with having a plausible plot (which it didn't), but rather to the acting skills of Claudette Nevins who was excellent from start to finish, especially in the final scene which did a good job of showcasing her acting. In fact, the last scene was good enough to have been written by a different writer.
As a previous reviewer said, Sam Groom probably did what he could with the foolish lines he was given but, overall, it was hard to watch him most of the time. While the women were updated to the late 70's, poor Sam was left dawdling in the late 50's, early 60's.
For "goof" fanatics, overhead mics can briefly be seen in the final scene.
