Continuity mistake: A business card from CityMet Bank comes into play. Humphrey points at the whiteboard with the card, but in the next shot the card becomes a magic marker. (00:23:00)
Continuity mistake: In the Scotland Yard office, DI Humphrey Goodman turns around and finds the teleconferencing DI Jack Mooney on screen. He announces to the team "I think I may have found him", and turns around, holding the phone closer to his chest. The movement is repeated in the next shot. (00:28:50)
Revealing mistake: Dwayne turns the volume of the computer in DI Jack Mooney's office; when we start hear him, the volume has gone up just a few notches, but it's already just as loud in the end as it is when Dwayne finishes to set it. (00:29:10)
Continuity mistake: Humphrey picks up the folders of the suspects from Mooney's desk using his left hand, and in the next shot they are in his right hand. (00:31:10)
Continuity mistake: Jack sits at the conference table, next to Florence. She moves the hand away from the notepad, but it's back on it at the cut. (00:34:20)
Continuity mistake: Jack tells the silly story of his cuff-collecting, one-armed uncle; in the reaction shot, Humphrey is sitting with his left arm up in a recognizable position, which changes in the next shot. (00:35:40)
Continuity mistake: JP is interviewing the widow. When she is reacting to the latest questions, her hand is open in the frontals, closed in the rear views. (00:37:00)
Revealing mistake: The photo found by JP in the newspaper archive is photoshopped so badly that you can actually see the line where Julian Wadham's face has been pasted onto the sailor's head. (00:44:55)
Continuity mistake: Humphrey puts on the banker's desk the printed article that establishes him as an old friend of the victim. The paper is in a different spot of the desk depending on the camera angle - you can easily tell by the upper left corner of the sheet, that either juts out from the other papers on the desk, or is properly on top of them. (00:45:10)
Continuity mistake: In the intro, Dominic Green greets the client from Saint Marie. A few people are passing by the car when he opens the door, but when he closes them those people vanished in thin air. (00:01:55)
Character mistake: In the first scene in the office of the dead banker, Jack is not wearing any gloves and touches the cufflink box freely without any precaution. (00:04:40)
Continuity mistake: The detectives are discussing the presence of the cufflink. Humphrey asks if "He's taken his own life in remorse", and the camera cuts to the deceased. Notice an iPhone on the desk by him. A moment later, the phone rings and Humphrey has to search the victim's pockets to come up with the phone. (00:04:55)
Continuity mistake: Jack and Humphrey are following the taxi in Jack's grey car, the registration number is DG60 SGY when they start following the taxi and LN63 FEJ when they park in front of it. (00:14:50 - 00:16:25)
Character mistake: The first term served by Dwayne's father is typo'd as 4 RS instead of YRS. (00:15:25)
Continuity mistake: Up to the point when Martin West says he took the gun to 'impress the lads', Florence has her hair to the right of her face going in front of the shoulder. New shot, and there's much of it combed back, and it keeps going back and forth until it's again all in the front in Florence's next close-up. (00:26:15)
Revealing mistake: Humphrey and the team receive the decisive last clue from Saint Marie; on the Scotland Yard PC, in the inbox there are tons of emails marked as 'today' that come from places like the Guadeloupe lab and instead days old. (00:34:35)
Continuity mistake: At the pub towards the end of the episode, Jack brings a glass of rum to Dwayne. He hands it to him with his left, but you can see in the shot when he begins to get seated that it's the right arm that he has extended. (00:48:10)
Continuity mistake: When Martha says "Yes" to Humphrey, the waiter in the background has his hands free. She kisses him in the next shot, and in order to clap with the others the waiter has to put down two wine glasses he was holding. (00:49:45)
Plot hole: The big locked room mystery is such only because the detectives build it up as one; they don't make any remark about the fact that the door can be locked from inside without the need of a key, they don't check the door frame or the lock (which would have revealed that it was bashed open while unlocked) and they do not even consider for a moment the idea that someone could have made a copy of the keys, which is the first thing anyone would have assumed. Not just that; nobody on the floor who has been working at the bank for years says anything about some cleaning lady they haven't ever seen before and that happens to be the first respondant to the murder.
In the Footsteps of a Killer - S6-E7
Continuity mistake: Dwayne pulls up from the evidence box the gun used for the murder; he holds it at the bottom part of the handle, but he his holding it with a finger near the trigger in the next shot. (00:05:30)
Answer: There's probably no particular reason. Sets and props on long-running TV shows often change as needed and for various reasons throughout a series run.
