Location: The County Courthouse early in the episode is actually the Malibou Lake Clubhouse which still exists. The Clubhouse has been used in several Perry Mason episodes like episode #113. Malibou Lake is also featured in episode #45 and 195. Posted by Eric Cooper, 9/21/2009.
About 34 minutes into this 1966 episode, Paul, Perry, and Della go to Natasha’s and you can clearly hear the 1965 #1 hit “Downtown” play in the background. Posted by Eric Cooper, 9/21/2009.
+ Also playing in the background is "Bye Bye Baby", notably sung by Marilyn Monroe in the 1953 movie "Gentlemen Prefer Blondes". jfh 10Aug2018.
+ A snippet of "Bye Bye Baby" is also sung by 'Sandy Chester' two episodes later in "The Case Of The Avenging Angel". jfh 14Aug2018.
Location: At the same time that Downtown plays, Paul checks the car registration of Cynthia Perkins. Her address is listed as 1416 No. La Brea. This is an inside joke. That address was not only the home of Perry Mason’s production company Paisano Productions from 1961 to 1966 but also where Raymond Burr often slept during the filming of episodes. It was originally Charlie Chaplin studios but is currently home to Jim Henson Productions. Submitted by Eric Cooper, 5 October 2010.
