It's not nice to bug Perry Mason
22 January 2013 | by bkoganbingSee all my reviews

Perry Mason gets involved with this episode's client when his boss hires the Drake Detective Agency to secure a top secret meeting where vital industrial information is exchanged about a desalinization process is discussed. William Hopper apparently didn't do his job because a rival company published that it had a breakthrough.

The client is Van Williams who once worked for the rival, the voluptuous Dee Hartford who is the sexiest looking industrial tycoon I've ever seen portrayed. Later on when Bryan O'Byrne who also was hired by Williams's firm to investigate is murdered and Williams found over the body and found by among other people Raymond Burr, I'm betting William Talman is thinking he has a slam dunk case.

Foolish man indeed as this episode takes us into the world of industrial espionage. Even Perry Mason's office gets bugged, but being the clever fellow Perry is, he sets a trap for the real killer, who only indirectly falls in it.

One of the best from the last season of Perry Mason.
