Butterfly in Shades of Grey - S12-E2

Plot hole: Columbo says that all the doors and windows at the murder scene were found to be locked. But Fielding Chase left the house through a door with a dead-bolt lock, wiping the doorknob and not locking the door.

Freshman Orientation and the Inventor of the Zipper - S4-E6

Plot hole: Memaw gets a call from Dr. Sturgis saying that he has moved to Waxahatchie and would she please call him back. He does not say the new phone number, and this was well before cell phones were in widespread use by the general public, so it could only be a land line. Memaw calls him back, although she could not know the number.

First Trap - S7-E11

Other mistake: Jack is taking photographs with a film camera that does not have an autowinder. He continues to take photos, but never winds the film.

Audio problem: When the Monster is tap-dancing to "Puttin' on the Ritz", the motion of his legs and feet do not correspond to the sound of the tap-dancing.

Continuity mistake: Brophy and Dr. Thorndyke are in the bathroom. The lid of the toilet is ajar, then is suddenly closed properly.

Factual error: When Mollie is scaring Ken in the station wagon, they pass a red Chrysler 300 twice (tip of the hat to the chase scene in Bullitt). The Chrysler is a 1965 model, and the scene takes place in 1964.

Factual error: Several of the "spies" use revolvers with silencers. You can't use a silencer with a revolver.

Things Were Different Then - S4-E16

Factual error: The car is referred to as a '73 Cadillac Eldorado. It has square headlights, and therefore is a '75 or '76.
