I recently re-watched Prescription: Murder and, of course, the weakest thing about it is indeed that Ray falls into a trap that a little kid should have seen coming. Another thing I noticed was that the sequence where Ray messes up the apartment to make the crime look like a burglary just seems to go on and on. Compare that with the similar bit in Murder by the Book, where we get the idea in a few seconds. Or any of the other phony break-ins that got staged over the years, for that matter. I did like the music that played while Ray was doing the dirty work, though. And, for being the first Columbo, P:M will always have a special place in the canon.
