See You in Court, Baby - S7-E3
Visible crew/equipment: When Briscoe visits Dennis, multiple set lights are reflected in his lenses. These reflections cannot correspond to practical fixtures within the house, as no such light sources are visible in the reverse shots.
See You in Court, Baby - S7-E3
Visible crew/equipment: When Dennis finds Marcia in the house, he sits down and she follows. The shadow of the boom microphone can be seen moving downwards on the wall behind them.
Deadly Misunderstanding - S7-E2
Continuity mistake: Throughout the episode, Jeff's hair appears very dark brown, almost black. In the rainy night sequence when he meets Melissa, his hair is dark black in the classroom—likely due to being wet—but shifts to a noticeably brighter light-brown tone once it dries. In subsequent scenes, it returns to its original dark brown colour. This variation cannot be attributed to lighting, as in multiple other interior scenes his hair remains consistently dark brown.
Deadly Misunderstanding - S7-E2
Revealing mistake: In the shot where Ralph lies dead, the padding used to accommodate the stabbed scissors protrudes under his shirt.
Deadly Misunderstanding - S7-E2
Continuity mistake: Floyd holds the gas canister with either one hand or both hands, depending on the shot.
Deadly Misunderstanding - S7-E2

The Murder of Sherlock Holmes - S1-E1
Visible crew/equipment: When Mr. Cellini meets Jessica Fletcher alongside her "refreshment committee" at the rehearsal, the camera's shadow is visible on his right shoulder when he walks to ask his assistant George to "sharpen up the last cue." (00:02:40)
The Sicilian Encounter - S6-E22
Visible crew/equipment: When Jessica sits down to read her mail, a square set light is reflected in the glass behind her. It does not belong to the house, as there are no practical square lamps positioned directly in front of Jessica.
The Sicilian Encounter - S6-E22
Visible crew/equipment: When Michael and Claudia are mugged on the street, actors' marks are visible on the ground.
The Sicilian Encounter - S6-E22

Funeral at Fifty-Mile - S1-E22
Continuity mistake: When Jessica walks from the house to the barn at the end, she is wearing knee high brown boots. By the time she reaches the barn they have been replaced with court shoes.
Revealing mistake: When the first scene at Emma's hideaway was shown, obviously the two characters Emma and Jessica were filmed seperately on the couch and then the film was put together (as both are played by Angela Lansbury). However Jessica did a lot of moving while she was talking, so Emma was looking straight across at where she had been, despite her bending down while she talked.
Audio problem: When singing "Goodbye little yellow bird" Emma blows a kiss to Oliver offstage, but she is still singing the song when she is blowing the kiss. Although it's possible she was pretending as it was part of the act, her voice wasn't even muffled by her hand.
Continuity mistake: When Emma was almost hit by a car she jumped up onto the edge of the wall and then back down onto the floor. When she landed she was facing the theatre door, but when Oliver came of the door and the shot changed, she was facing away from the wall. This happened in the transition from stunt person to Angela.
Tinker, Tailor, Liar, Thief - S8-E15
Revealing mistake: In the second close up shot of Nigel Atkins lying dead, after Jessica drops her Harrod's bag in the chair, it is obvious he is still alive as you can see his pulse on the side of his neck.
Factual error: At the end of the episode after Wayne is shot, there is a brief shot of the outside of the hospital where he has been taken. The sign outside the hospital says Dalesboro, Ohio. Why would someone shot in coastal Maine end up in a hospital in Ohio?
Deadly Lady - S1-E2
Revealing mistake: When Howard Duff's two daughters enter the police station to identify his body, the cop pulls back the blanket. Howard's eyelids are moving even though he is supposed to be dead.
