Here's what I don't understand:
At the end, it is revealed that Dr. Flemming has another ('real') girlfriend, whom he plans to marry, after dumping the actress. It turns out that he was just using the actress girlfriend in order to kill his wife.
BUT>>> Why in the world wouldn't Flemming think that (once he dumped her for the other woman), the acress would not go and immediately tell the police of the murder?? Hasn't the doctor ever heard of "Hell hath no fury like a woman scorned?" Man, I'd turm him in so quickly, his head would spin. Funny how he never seems to think about this as a possibility.
Although she was an accessory to the murder and so maybe would keep quiet, I feel it was only likely/a matter of time before the police would be able to connect the two anyhow (although her sentence would probably be minor).
Aside from this, I like this Columbo quite a lot.
