Common Perry Mason tropes
My wife and I have seen every episode many times. I always like to point out these re-used story elements when we see them. What are some others you've noticed?
The unlatched front door that opens when somebody knocks. That ALWAYS means there is a dead body inside! Always!
Identical handguns. There were a few episodes that featured identical handguns. Perry always creates confusion around them one way or another, secretly swapping them or in one case firing one of the guns into a tree in an area related to the crime.
Mis-identified bodies. A wreck or plane crash in a remote area, with no witnesses. Sometimes, Perry's client decides to switch identities with the deceased.
