Episode #4.3 - S4-E3
Plot hole: Five people in total are on a remote location, but they have food poisoning, so severe that they call in the paramedics. Humphrey arrives when they are being taken care of already. During all the time it took for the doctors to arrive, and when the actual rescue was there and was administering help, nobody bothered to check on the victim in his tent - if anyone did, they would have found him dead, since the poison killed him in 30 minutes. The son, the lover and the good friend of the victim, nobody thought about him for a moment.
Episode #4.3 - S4-E3
Plot hole: The killer poisons the victim's belonging when they met early in the morning - that means that the victim stayed the whole day with the poison in the pages of his journal he always brings with him. Yet the murderer's plan required the poisoning to happen at a very specific and precise moment: the end of the day after they'd all had eaten together the stew with the non-lethal dose. It is something that they couldn't have planned at all the way it is described, not when they did the poisoning so far in advance.
Episode #4.3 - S4-E3
Continuity mistake: Humphrey walks into Henri Garon's place, camera in hand, showing him video proof of his mischief. In close-up, the lanky policeman's pinky finger is off the camera, while in the shot before and after the finger is on the camera lens. (00:37:15)
Episode #4.3 - S4-E3
Character mistake: On the website of the Saint Marie Heritage Society, there's an ample mention of Catherine's bar where the society gathers. However, it mentions the lovely "Catherine Duval" serving drinks - Catherine is Camille's mother, and their last name, as also present in the credits, is Bordey, not Duval. (00:20:45)

Continuity mistake: Goodman and Camille are driving back from the chat with the treasurer of the Society and wonder if $4,000 are enough to motivate someone to kill. In this part of the scene, Camille takes her hand off from the steering wheel, but it's back in the reverse shot. (00:18:15)
Episode #4.3 - S4-E3

Continuity mistake: When Florence passes the sheet with Alan Butler's info to DI Humphrey Goodman, on the background Dwayne is working at the computer and glances towards them - but as the paper reaches Goodman's hands in the next shot, Dwayne has changed stance and is sitting comfortably watching them. (00:12:15)
Episode #4.3 - S4-E3
Continuity mistake: When Camille spots the camera and asks Henri Garon to give it to the authorities, in close-up the camera is fairly close to the side of the table by him. In the wider angles though, it's noticeably more distant, at least compared to the distance with the shorter side of the table. (00:07:50)
Episode #4.3 - S4-E3
Continuity mistake: During the first interview with the suspects, at Catherine's, the drinks on the table are positioned differently depending on the angle; for instance when Imke Sandt mentions the "foraged for other ingredients", the slice of lemon on her glass is on the part of the rim closest to her, but when Camille begins her follow-up question the slice moved to the opposite side. (00:07:30)
Episode #4.3 - S4-E3
Continuity mistake: Dwayne goes through the personal belongings of the victim he just catalogued. In the background, watch for Florence; she is not holding a pen, her right hand is on the bloc notes. Camera closer up, and she is holding a pen. Moments later, Camille is writing with her pen that has the cap fitted on the top, except in the last shot (when Dwayne mentions the authentic meal) when it's gone. (00:05:35)
