As the Perry Mason series wound down many episodes had conclusions which were very shallow.Sadly this episode is one of those which does not have a credible ending.If we are to believe that a highly rated radio personality murders his boss after being threatened with replacement or being fired then Howard Stern would have murdered 9-10 times by now.A successful radio personality can always find another job.The poorly thought out ending makes this an extremely disappointing Perry Mason episode.It's no wonder that Burr and Hopper were unhappy doing the show at this point.The quick,very poorly written ending ruins the episode.
