Location: In the scene where Paul is on his way to W. L. Picard’s office, two California state highway signs can be seen, one for route 23 and the other for route 118. These roads actually converge in the city of Moorpark, not in the “Pinon City” of the show. See here. Submitted by Steve Fox, 10/7/2004.
+ On the "here" page there is a query about arrows under the highway signs. There isn't anywhere to answer it there, so I figured I'd post it here. The arrow under 23 means "go straight to follow Highway 23." The arrows under 118 mean "go straight or turn left to follow Highway 118, depending on which direction you are heading.". OLEF641, 12/16/16.

That Mysterious Black Bar that appears in the scene with the roadsigns is there to cover up a sign. More here. From a post to the Perry_Mason Yahoo! group by Rich Erickson, 12/16/2006.
+ I scanned this episode on the Perry Mason 50th Anniversary DVD for the scene of the Mysterious Black Bar and find that there is no black bar. It looks like the scene has been stretched vertically to eliminate the bar. Tricky! Posted by daveb, 4/8/2008.

I don't think they stretched the frame vertically. It looks more like they just expanded it to 4:3 which also cropped out the left side. The top of the frame is right below where the bottom of the bar would've been. Submitted by Arisia, 03/15/18

The building that Paul enters at the intersection with the mysterious black bar appears is located at 601 Moorpark Ave. The building sits on the NE corner, so the camera was set up just north of the building in the middle of the road apparently. It has changed little save for the awnings over the windows and doors. It is also the location where Aunt Sarah enters the police station in another scene. Posted by Kenmore, 12/02/2016

The restaurant that Paul enters to meet Perry appears to be a building that sits at 105 E High Street, just one block east of the building that Paul entered with the "mysterious black bar" over the top. Today, it's a liquor store and the facade has changed somewhat, but it otherwise looks pretty close. Submitted by Kenmore, 12/02/2016
+To the left of the reastaurant door is a poster in a frame advertising the movie "Dos Tenorios de Barrio." This is a comedy, released in ... 1949! Here is an alternative version of the poster:

Goof: I noticed a blooper in the opening scene. When Adam West looks at the registration for the truck, it says it is a “Ford Pickup.” In the next shot, when the truck pulls up it can clearly be seen that it is a GMC truck. Submitted by J Fleming, 12/31/2009.

Fred Swan's Auto Registration form, spied by J Fleming on Car (1), reads:

  • NAME.....Fred S. Swan________________Code--04
  • ADDR REGISTERED OWNER...1040 No. Las Palmas
  • Licence No.....NFL252____Engine No XCC56338977
  • Make.....Ford___________________Type.....Pick-Up
  • First Sold.....3/8/58_________________Fee $....21.35
  • Date Issued....1/25/61
  • Registered Owner....Fred S. Swan

As per normal, we're only supposed to notice the owner's name: this vehicle isn't a Ford, the plates aren't NFL 252 and Fred's yet another resident of 1040 Las Palmas. What's interesting, though, is that the "Date Issued" entry is about the right time for this prop to have been prepared for this episode. Added by Gary Woloski, 1/11/12.

In another entry of TCOT All-Purpose Address, the above truck registration indicates that Fred Swan is yet another resident of 1040 N. Las Palmas in LA (also used in episodes #78, #89 and #100). As daveb mentioned, Hollywood Center Studio is the long-time tenant of that address, and at their website the Mason series appears in the “Featured List” of TV productions filmed there. Submitted by FredK, 1/3/2010. There’s more about this on the Location Trivia page.

Eloise Hardt makes her only Perry appearance here as Marta Wiltern. When I initially watched the episode, I thought she was Barbara Bain, the resembleance is remarkable. In 1968 Eloise Hardt’s only child, Marina Habe, a 17-year-old college student, was kidnapped and murdered. The murder was never solved, but a lot of people believe it had something to do with the Manson crowd. Submitted by PaulDrake 33, 29 January 2010.

Take a good look at Marta Wiltern's motel room. The same set, with some minor changes, appears to be used in the next episode, #116 TCOT Difficult Detour. Submitted by Dan K, 23 February 2020.

Character Names: Although left out of the credits, Miss Sarah’s last name is McKay, and Prosecutor Hale’s first name is Jonathan. The prosecutor refers to a officer named Gene Barr, but it may or may not be the same Policeman in the credits. Submitted by gracep, 11/8/2010; updated 7/7/2011.

Sightings: The food at Mr. Needham’s restaurant in Pinon City must be awfully good, because it lured Distinguished Gentleman #1 from L.A. to the little town. We see him sipping tea and talking enthusiastically to his companion as Iris McKay (Enid James) storms in. One of the few times he is so emotive! Submitted by gracep, 11/8/2010.

When Iris arrives in Piñon City she apparently rents a car - the same car Paul later drives. So what’s with the bicycle? DOD 10/08/19
+ Iris rides home from the train station with her aunt, then borrows that "machine" to drive to town. jfh 06Dec2023

TCOT Curious Coffee Set: The diner in Piñon City uses the Curious Coffee set. DOD 10/08/19
+ I use the Curious Coffee Set as a marker of what is shot on location versus what is shot at the studio. They would never transport those precious props to Moorpark, would they? Submitted by catyron, March 13th, 2021.

Rather a lurid selection of magazines at the train station - ‘Fantastic’, ‘Lonely’, ‘Model’, ‘Shock’! DOD 10/08/19
+ At least two of the magazines were used in previous PM episodes. Kilo 12/17/2019.

CARS. (1) 1948 - 1953 GMC PickUp Truck with camper pod, Lic No RKM 126, med color, Fred Swan. Note GMC badges on nose and sides of hood. Appears to have new-fer-'52 pushbutton door handles, otherwise could be any '48-'53 GMC FC-Series light truck (split windshield is pre-'54).

Background Cars: (a) After Iris excuses herself from Miss Sara and "W.L." she runs past a 1960 Chevrolet Corvair 4-Door Sedan, med color (wiki article here). The car beyond the Corvair looks like a 1954 Dodge (note the unique taillights). Even photos of this car are rare!

  • (b) While driving his rental-Buick, Paul passes a parked 1958 Edsel Villager station wagon, 2-tone light & medium.
  • (c) A 1961 Plymouth Savoy 4-Door Sedan County Police B&W, is parked at the police station when Miss Sara drops in to give Chief Hagerty a durned-good piece of her mind.

++ Near the beginning, when Iris and Miss Sarah were at the station talking with Dan, Miss Sarah referred to it as the “car”. Twice. Kilo, 9/15/2020.

Long, sideburn of the Law Although Paul is too good natured - or is it too unobservant? - to point it out, neither of the gendarmes who arrest him for beardlessness sports one either (though they do both have mustaches); in fact, of all the characters in the show only Fred Swan sports one...ironically. Submitted by Notcom, 120415.
>>> As a matter of fact, one of the officers points to his mustache with his baton as he tells Paul that all men must wear beards <<< jfh 23Jan2023

In the early parts of the Episode, Adam West sports sideburns. By the court scenes, the sideburns are gone.

Marta Wilburn pronounces her maiden name "Buzz-kirk," though Perry and others always say "Buss-kirk." You'd think Marta would know, right? Ed Zoerner, 2/29/24.
