Episode #3.4 - S3-E4
Continuity mistake: At the concierge during the first interview, the phone rings. Simone asks "May I?" pointing with her left hand, which becomes the right hand after the cut. (00:09:00)
Episode #3.4 - S3-E4
Other mistake: Humph points out a suspiciously large cash transfer that happened 'three months ago'. On the bank statement, the transfer is shown as happening on Feb 3, so we should be around May. The security footage Dwayne reviews established that the murder happened on the 7th of March. (00:22:00)
Episode #3.4 - S3-E4
Other mistake: When Camille checks out Natasha's bank statement (a picture of it, which is kinda odd as you'd expect another file format), it contains amongst many other payments also a cash transfer to Paul Bevans for €10,000, but the subtotals do not reflect that at all (from over 18k Euros goes to 12k). There is also the not negligible detail that her name is misspelled in her own bank account; she is "Natasha Thiebert" but the statement spells it "Tieebert." (00:22:05)
Episode #3.4 - S3-E4
Continuity mistake: Summing up the lack of progress in the case in front of the whiteboard, Humphrey points at Bevans' picture with his right hand at first in the overhead shot, which becomes the left hand at the cut. (00:25:30)
Episode #3.4 - S3-E4
Continuity mistake: When Humphrey foolishly lets Catherine pick the dish for dinner, he lifts the menu and only the menu off the table, but in the following shot he has one of the blue paper towels underneath it. (00:27:30)
Episode #3.4 - S3-E4
Continuity mistake: When Catherine brings the casserole of deadly confit de poulet, Humph unfolds the paper towel in the first shot but it's still perfectly folded in the next. (00:28:10)
Episode #3.4 - S3-E4
Other mistake: When Dwayne stalks Simone, his sidecar is smack in the middle of the driveway when she approaches; he drives away towards the left but he is then lurking on the right side of the road as she drives off. All of that with his front light on. Not even a blind person could Miss it, and he'd have to swerve wildly to get in that sort of position. (00:28:10)
Episode #3.4 - S3-E4
Continuity mistake: Dwayne is reading the local newspaper when Camille and Humph get back from the hotel. The paper folds in opposite directions in the two separate shots. (00:36:40)
Episode #3.4 - S3-E4
Continuity mistake: The hands on the close-up of the phone record sheet are inconsistent with the wider angle (Goodman's left hand should be in frame). (00:37:10)
Episode #3.4 - S3-E4
Other mistake: The phone records Fidel shows are of February, with Valentine's day being the latest entry. It is inconsistent with practically any other inconsistent bit of the episode (bank statements in February listed as 3 months prior, security camera of March, fingerprint file dated February 9th). (00:37:15)
Episode #3.4 - S3-E4
Continuity mistake: When Goodman crawls to get the poison vial, it contains just a bit of liquid left at the bottom. Later when he checks it out at the station in greater detail and many close-ups, it's over half full. (00:40:40)
Episode #3.4 - S3-E4
Continuity mistake: During the denouement, Helen Walker's hair goes from still to windblown and back suddenly between cuts multiple times. (00:45:00)
Episode #3.4 - S3-E4
Continuity mistake: In the final part of the enquiry, Goodman pulls out of the evidence bag with the bottle of poison; the bag is turned differently between shots (check out of the small ribbed part in the corner, the bottle's cork). (00:45:40)
Episode #3.4 - S3-E4
Continuity mistake: Simone's reaction shot to Helen saying "I wasn't even here!" is flipped, as the position of her hair makes obvious (she wears the hair combed on the opposite side throughout the whole episode). (00:47:05)
Episode #3.4 - S3-E4
Other mistake: Twice in the episode Fidel gets from the computer a fingerprint match for Adam Frost. The date of the sample is February 10th, which not only is inconsistent with the supposed timeline of the episode (the security camera puts the murder on March 7th, and the previous episode was set in the fourth week of March as per the gigolo's appointment schedule). but also differs from Natasha's fingerprint date, February 9th. The murder was discovered in the morning, so the victim's prints have been taken the same day as the suspects'.
Episode #3.5 - S3-E5
Continuity mistake: Inspecting the study where the victim supposedly killed himself, DI Humphrey Goodman at one point rattles the window handle and then at the cut stands side by side with Commissioner Selwyn Patterson. In the shot from that particular angle, which repeats itself a few seconds later when he says it's "one of those things" after he made an exaggerated shooting gesture, his right hand does not appear gloved (and he tucks it both times rather quickly under the other arm), while he wears latex gloves in the rest of the scene. (00:05:20)
Episode #3.5 - S3-E5
Continuity mistake: The two detectives plus the Commissioner have broken to the family the news of the case being a murder investigation. They walk down some stairs discussing the case; Dwayne' scooter is visible in the background, shadows in its vicinity. When Patterson bids his farewell, Camille and Humph get called by Dwayne; the shadows by the bike now extend through a larger space all of a sudden. (00:09:05)
Episode #3.5 - S3-E5
Continuity mistake: Camille tells Humph that Marlon Croft they just spoke to is "probably" her father. He reaches them outside; during the scene the passersby walk at relaxed pace yet the street crowd behind Marlon completely changes after the brief cut on Humph and Camille. (00:13:30)
Episode #3.5 - S3-E5
Continuity mistake: When Camille tells her mom about Marlon being on the island, she turns around theatrically asking back "Your father?" Throughout the scene, Elizabeth Bourgine's arm position and stance appears subtly inconsistent between shots, and Camille goes from having one hand at the hip to the arm flat against her side at the cut following "It's just bad luck." (00:14:10)
Episode #3.5 - S3-E5
Continuity mistake: There is a cut when Humphrey says "if you caught your dad having an affair..." Camille's bottle of fictional beer is then facing a different direction. (00:19:25)
Answer: Most likely they had only tropical exotic drinks, he wanted an old fashioned English beer.
