This was the last episode of the police detective series before it morphed into a spy show. The performances by guest stars were very good, and the murder mystery was legitimately solvable from clues and motives revealed during the course of the show. Nevertheless the suspense of who was the killer was kept up until the end, with all candidates in the running. A big plus was the method of murder itself, which was wholly original. And Tim finally gets a girlfriend. If only Gene Barry didn't insist on doing literal song and dance routines this would be a 10.
