I really enjoyed this episode, one of my favourites. I don't know how others felt, but to me it was darker and felt different to other Columbo episode.
One thing though, how sloppy was the second murder? Didn't it occur to the Commissioner that the coroner might find soap in her lungs?
How do you think the Commissioner would have killed her if she wasn't in the bathtub?
He would later have witnesses to her being thrown in the pool and "drowning" there so he assumed that the constituency of the water in her lungs would not be questioned.
Agreed. I used to watch that episode over and over. It's really good! As of right now, I am watching Colombo almost every night, especially before going to bed.
