The Murder of Sherlock Holmes - S1-E1
Continuity mistake: During the scene at the train station, Jessica's nephew introduces to her Kitt Donovan from the publishing company. Just as he says "in public relations", a man pops in the foreground - it is an extra that walks out of the rail car. In the reverse shot that follows, the same extra is only then coming out of the train. (00:09:35)
The Murder of Sherlock Holmes - S1-E1
Continuity mistake: Episode 1-0, "The Murder of Sherlock Holmes"; Mr. Giles opens the door of the antechamber of his office, finally putting an end to Jessica's long wait. Grady right away at the first click of the lock takes his hands off his pockets and tidies up his sleeves. But in the next shot when Grady actually enters and talks to the secretary, Grady is still with his hands on his pockets repeating the gesture. (00:10:10)
Another Killing in Cork - S11-E20
Continuity mistake: In the opening exterior shot of the train, it has at least six brown and green carriages. However, in the next exterior shot, the train is made up of three brown and cream carriages.
Plot hole: When Beverly is killed the killer shuts off the main power switch which would have turned all the lights off in the house, not just those in the bathroom. (01:31:00)
Continuity mistake: When Danny Kincaid is at the beach, he is wearing green shorts when he is taking his shirt and shoes off, but he has blue and black shorts on when he goes into the water. (00:19:00)
Character mistake: Ottawa is misspelled "Ottowa" on Nicholas Jenson Davis wanted picture.
Continuity mistake: When Ron Moody runs into the sea in pursuit of a suspect trying to escape, he shouts at Jessica to "Get the package!" In the next shot we see Jessica reluctantly follow him in, with a clear waterline from a previous take showing on her dark overcoat/cloak.
Murder of the Month Club - S11-E10
Factual error: When Joellen removes the manuscript from the locker at the Yonkers bus station, you can see the address it was originally mailed too. The zip code is 10205. This is incorrect. All Buffalo, NY zip codes start with "14xxx" a zip code starting with "10xxx" would be much further down state.
Revealing mistake: When the episode ends and Jessica drives the buggy, she is replaced by a very obvious stunt double with a wig that not only does not resemble her hairstyle, but it's grey as opposed to her light blonde colour.
Visible crew/equipment: After Seth drives Jessica downtown, lights, crew, and filming equipment are reflected on the car window.
Continuity mistake: When Jessica is having dinner, his glass swaps between full or almost empty depending on the shot.
Audio problem: The cabin floor is carpeted, but the footsteps heard are of a hard tiled floor.
Audio problem: Several times during the episode, when someone is walking on a rug, the sound of footsteps is that of a hard tiled floor.
Character mistake: When the corpse is taken out of the water, he moves his mouth.
Factual error: Celestial navigation can determine one's position on the earth's surface to within about one mile, not precise enough to give the location of a buried treasure. It also requires more than a sextant. It requires tables published in a nautical almanac (which is updated each year), charts on which to plot lines of position, and an accurate chronometer that is set to the precise time at the Prime Meridian (Greenwich Mean Time).
Factual error: "Witches" were burned at the stake in Europe, but not in America. In America, they were hanged.
Continuity mistake: When the episode begins, Jessica is having a meeting with Sally Wilson, who hangs a bag over her shoulder. A shot later, her bag is down and she is hanging it again.
Audio problem: When Buck walks to the bar downstairs and meets Mrs. Oates, the sound of their footsteps is that of tiled floor, but they're walking on a rug.
Revealing mistake: Kat pumps her shotgun several times with no shells coming out.
Mirror, Mirror, On the Wall (2) - S5-E22
Other mistake: When the sheriff finds the apple, the bitten side has a fresh white colour, instead of the brown colour it should have after the many hours passed.
