CARS: 1957 Ford Skyliner retractable, black (Mason), 1957 Plymouth convertible. From The Cars by Greg Cockerill.
+ The Plymouth is Sybil Granger's 1957 Plymouth Belvedere Convertible with V8 engine (denoted by wide "V" on fender forward of front wheel). Screenshot at 12:09 of the episode is here. Sybil's car was produced after mid-Jan 57: a close look at 12:17 shows that it had six pairs of narrow vertical slots in the underpan behind the licence plate, like this. Cars produced before mid-Jan 57 had six wide slots, which apparently let in too many gophers to plug up the radiator. The 57 Plymouth had very good handling thanks to its new "Torsion-Aire Ride" which included torsion bar Front Suspension. Read about the car here. See Comments section for "1957 Headlight Oddities". & At 16:10 we see the Drake Detective Agency radio car manned by two of Paul's agents. It's a black 1957 Lincoln Premiere 4-Door Sedan.

Anomaly: Robert Bice is listed as Hurley in the closing credits but is identified as Frank Faulkner by Paul Drake.

In this show George Lutts complains to his daughter and son-in-law because steak costs $1.34 a pound. Can you imagine what he would have to say about today’s prices? Submitted by PaulDrake33, 6/25/2008.
+ Steak was actually pretty expensive in 1957, if that price is representative. Using the general CPI, $1.34 at that time equates to $11.32 in 2015 prices. However, the USDA reports the price of sirloin steak at $8.72 per pound for November 2015, and that's even after some large increases in recent years. So in relative terms steak is cheaper now, and was more expensive then. JohnK, 24 December 2015
++ The way Herbert is sawing at that steak it might as well be $.34/lb! Kilo 5/25/2020.
+++ Update on the steak question - according to, $1.34 in 1957 would be $12.73 in 2021. A quick check of steak prices at a local mainstream supermarket, Vons (a local marque of Safeway), reveals (regular) price per pound for these three fairly common steak types: boneless sirloin-$11.99, bone-in New York-$14.99, boneless ribeye-$16.99. So, it looks like, to me at least, she probably was serving sirloin, which can be a bit difficult to cut if you don't have a steak knife. OLEF641 6/7/21

The (shooting?) script for this episode is dated 10 June 1957. At least 7 episodes have scripts dated earlier. So while it was the 3rd episode broadcast, it was probably no earlier than the 8th filmed. Submitted by billp, 3 November 2009.

Here is the putative route of the “second” taxi trip Mrs. Granger took. The actual route described is a plausible one. The taxi is followed south on Roxbury Dr. It turns east onto Santa Monica Blvd. and goes past Hillcrest Dr. While on Santa Monica, it picks up Drake’s man. It then goes north on Doheny Dr., heading towards Sunset Blvd. While on Doheny it presumeably drops off Drake’s man and picks up Mrs. Granger and company. They tell it to go west on Sunset. It then probably goes south on Whittier. Mrs. Granger and friend exit at Whittier and Wilshire. This is somewhat southwest of where we, the viewer, initially picked up the trail. The route followed by the taxi is circular in nature. Frankly, it seems possible, given this description, that Mrs. Granger could have been with Drake’s men when this road trip began and ended. Interesting. I guess if you wanted to do a Perry Mason “re-enactment,” you could trace out this route and check out the scenery. Submitted by billp. 26 November 2009. [Here's the route on Google Maps. Use Street View to check out the scenery. daveb]

Uncredited Actors: Don Anderson makes his third Mason appearance here (unless you count episode 2 twice, since he was in two places in the courtroom). He’s a courtroom spectator seated directly behind Herbert Dean played by Robert Cornthwaite. (See Uncredited Actors). Submitted by FredK 29 September 2010.
+ In an initial long shot of the courtroom, he appears in the back row, but then in a closer cut to Burger, he disappears. Submitted by gracenote, 8/23/2011.

Sightings: Blue Collar Guy can be seen with his arm on the back of an attractive young brunette among the spectators exiting from the first aborted hearing, while Tragg is stalling Mason in the foreground. (See Who Is That?) Submitted by alan_sings 30 September 2010.
+ (Also Continuity Error:) In the courtroom gallery during the first hearing, we find Distinguished Genetleman #1 in the back row, Distinguished Gentleman #2 in the front row, on the prosecutor’s side. In the second hearing the two gentlemen sit together in the back row on the other side of the courtroom—that is until DG #1 shows up again on Burger’s side when he calls a witness. Submitted by gracenote, 8/23/2011.
+We find Distinguished Lady #4 in her favorite spot in the back row on Perry's side of court. Submitted by BigBill767, Nov 11, 2016.

Star Trek Alert: Gail Bonney (who plays Harriet) has the distinction of being the first Perry alum to appear in the original series Star Trek. She would be the first in a long line of Perry actors to enter the Star Trek universe, including of course Leonard Nimoy, George Takei, and DeForest Kelley (Shatner, alas, never had a role in Perry - what a loss!). In its heyday, it wasn't unusual for a Perry episode to include two, three, or four actors who would go on to join the crew of The Enterprise (or appear as an alien). Indeed, the Star Trek pilot had no fewer than five former Perry actors, including the guy who wore the gorilla suit in TCOT Grinning Gorilla, arguably the worst Perry episode. Bonney was credited as "the second witch" in the Original Series second season episode "Catspaw", wearing lots and lots of makeup. She appeared in two Perry episodes: this one, and TCOT Flighty Father, as the maid. Submitted by MyFavoritePolarBear, 1/14/23.

Additional Hallmark cuts: Part of the dinner conversation when Lutts asks Herbert about Sybil "Did you see her there or didn't you?" and Vinnie says "every day last week"; Burger complaining about endless and purposeless cross examinations; Mason questions Sybil about the distance of the shot; cabbie being sworn in; cabbie saying he took Sybil to Brent building; Bruce asking Mason if he can help and Mason saying he's a little late; conversation between Vinnie and Herbert after Perry, Della and Paul leave; Burger's first objection to Mason's shooting-the-blank demonstration; Mason's telling Sybil to keep a poker face and Ruth being sworn in; Ruth saying she's Sybil's friend and Burger asking if the relationship goes farther. Submitted by Wiseguy70005, 7/04/12.
+ In the syndicated version I recorded on 7 Mar 2014 on MeTV, it went from Sybil and Ruth getting in the cab to four minutes twenty seconds of commercials, then to the start of the trial. We never do learn why Burger considered Sybil to be a suspect. Submitted by Alan Smithee, 3-10-2014.

Gun: The murder weapon was a Colt Official Police. Submitted by oldgray, 2/27/2014.

In the novel the murder was committed on June 3rd. In the episode the date was May 3rd. In both the novel and episode Roxy returned the gun to Sybil's husband on May 30th. So in the novel she returned the gun four days before the murder and in the episode almost a month afterward. Submitted by Wiseguy70005, 1/20/15.

IMDb credits Annabell on 247 episodes. What does the "S.C.H." after her name stand for? Mike Bedard 3.26.15
+ Good question. I guess it's for Society of Cinema Hairstylists, Inc., see for example here, incorporated in California, on April 7, 1955, and now dissolved. However, I didn't see Annabell's name listed in the episode's credits on the 2006 Paramount DVD, only Mel Berns, so I wonder how her name got listed here as an accomplice. lowercase masonite, 2/2/16.
++ Annabell has 247 PM "Makeup Dept." credits, including "Nervous Accomplice," her 2nd IMDb citation. You're right: she's Not listed in the Closing credits: I must have found her on the IMDb list. Mike Bedard 7.12.16.

Perry has a workshop? In other episodes we've seen his office in the Brent building and we've seen his apartment. But this is the first (and only) time we hear that Perry has a workshop. Perry tells Paul to collect all the wood and pipes for the shooting stand and bring them to his workshop. Submitted by Kilo 2/22/2018.

This is the first of two PM appearances for Jean Howell, who in later life became an advocate for the cleanup of Santa Monica Bay. Jean Howell passed in Santa Monica in 1996 at the age of 68...MikeM. 4/24/2018

Maggie Hayes first of four appearances. Would also play a character named Granger in the movie Good Day For a Hanging. Perry remarks to her to the effect that she has an unusual marriage..she has an even more unusual marriage in TCOT Ominous Outcast, and Perry will comment on that as well. Notcom, 091919.

Morris Ankrum the first of his 22 appearances. He will be remembered as the trial judge in The Postman Always Rings Twice (it's a remarkably succinct proceeding that goes from reading of charges to sentencing in all of five minutes!) Notcom, 112822.

Second episode in a row where a couple is off to their honeymoon. Submitted by HamBurger, 9/12/2020

OK folks, here is a real anomaly: In the shooting shack, there is a lamp above the desk/table. Where is the electricity coming from to power that lamp? Doesn't seem like there is electricity to power that for miles. I didn't hear a generator in that scene. Submitted by HamBurger, Jul. 24, 2021

A possible answer is that there was a generator when the shack was in use. But that generator was removed when the development stopped. The trash on the floor indicates that the shack may not have been in use for some time. Submitted by Kenmore 11/28/2022
