(at around 19 mins) After Drake tells Mason what he's learned about the death of Sam Carlin, Mason tells Drake to meet Mrs. Fargo (Angie Dickinson) at the bus station and to take Mason's car - a 1957 Ford Skyliner, but when Drake arrives at the bus depot, he's shown getting out of a 1940s DeSoto seven-passenger sedan taxicab.

Perry actually tells Paul to charter a plane and FLY to Harristown to beat the bus. So Paul would have taken Perry's car just to a local airport and, after arriving at an airfield in Harristown, he would need a cab ride to the bus depot. So, the incongruent vehicles are not a mistake.

At the fire, Perry is shown talking to a couple, then the next shot has him staring at the fire with no one around, and then he is shown again talking to the couple.

In the Quotes section, Angie Dickinson's character is referred to as Marian Gallagher, but in the credits she is listed as Marian Fargo. Gallagher is her maiden name, but in the show she went by her married name of Fargo.

Paul Drake describes Marian Fargo's car as beige and black. Later, on the witness stand, the airport parking lot manager George Danvers describes the same car as beige and brown.

After the woman realizes she was mistaken about her upcoming testimony, Burger tells her she would have been guilty of perjury. One is guilty of perjury only when it can be proven the person knowingly lied under oath, not for honest errors.

When Mason and Street enter Carlin's house, the address number - 6920 - is visible on the door. When Mason leaves moments later, the exterior shot shows the house number over the mailbox.

Correction: The house number does not appear on his door, only above the mailbox. (Later, when Mason and Drake find the dead husband in a different house, *that* door had the house number on it, but it wasn't 6920).

Prior to the house explosion, Paul calls Perry; it appears to be evening time. The shot goes to Perry standing outside the house, and it is apparently daytime. When the fire engine is rushing to the site, it is nighttime. Shots of the crowd watching the fire have the sun shining in their faces.

First, the shot of Perry outside the house is not nighttime. It's very definitely intended to be night - the shot is intended to be a well-lit area of the street. Second, it's not the sun shining in the faces of the crowd - it's the light from the fire. The light is flickering, meant to indicate the flickering light of the fire.

When Perry asks Paul to call the fire department, he's gone for only about three seconds and returns promptly to join Perry. He would have had to find a pay phone to call the fire department and would have been gone for several minutes.

Correction: It was not uncommon for Los Angeles city streets to have "fire call boxes" to summon the fire department simply by pulling a lever - there were nearly 200 in LA sixty years before this episode.

Actually, it's more complicated than that. William Hopper apparently didn't wait for the director to yell "cut" before going back to stand beside Raymond Burr in anticipation of filming their lines for after the fire had been put out. What's more, the editor also failed to end the sequence of when Hopper re-enters the frame before doing the fade-out/fade-in transition to the stock photography of the fire engines racing to the fire.

(at around 9 mins) Mason and Street arrive to deliver money, and the raincoat on hall tree is wet. A short time later, Mason departs, and the raincoat is dry.

Correction: The raincoat *is* wet upon Perry and Della entering and leaving the house. However, as soon as they leave, the raincoat's true owner - Arthur Fargo, Marian Fargo's husband - comes in from a back room and after a very brief conversation with Samuel Carlin goes to leave. He grabs his raincoat and at *that* time the raincoat is dry.

When the waiter brings the telephone to Perry at the restaurant, he approaches the table from the left. A long cord would have been trailing on the floor. After Perry completes the phone conversation, the waiter returns and picks up the phone and leaves with it to the right of the table. The cord on the floor would not have allowed him to go in that direction.

Correction : The first waiter brings in the phone with the end plug in his left hand. He sets the phone on the table and bends over to plug in the cord behind Mason. When the second waiter enters, there would be no problem navigating around Mason and the cord.

When Burger objects and gets Ms. Maynard to be a witness for the prosecution instead of the defense, Burger stands to start his examination, the shadow of the camera can be seen on Burger's right shoulder.

Marian instructs Perry to examine the file and verify it is authentic and complete. Perry knows nothing about the file and so would have no idea what it should contain so he could not verify its authenticity or completeness.

After discovering the body, Perry dials the phone to call the police but dials only six numbers. Back in that era, you could dial a number within the same exchange by omitting the first number, so it was possible to dial only six numbers rather than all seven.
