Any Old Port in a Storm - S3-E2
Audio problem: Pay phones always dropped your coin into an internal cash box when you finished your call. In the bar, Columbo makes two calls, and after the first, we hear the coin drop as it should. When he finishes the second call, we should hear that coin fall, too, but it doesn't. (00:34:05)





Answer: Columbo deduces that the first blow must have been to the front of the head, the force causing the victim to fall backwards and hit the back of his head hard on the ground.
