Episode #2.1 - S2-E1
Continuity mistake: In the prologue, Roger Seymour is snogging his attractive young lover. She has her fan in her left hand when he says "I won't be long", but the fan is gone (and in her right hand) in the next shot. (00:00:40)
Episode #2.1 - S2-E1
Continuity mistake: When Richard says "Mothers can be real hazards, particularly yours", he has his right hand on the steering wheel, the left in the next shot. (00:04:30)
Episode #2.1 - S2-E1
Continuity mistake: When the doctor introduces the various guests to Richard and Camille, the close-up on Alex features him at an angle and under a lighting that have nothing to do with the rest of the scene. (00:08:55)
Episode #2.1 - S2-E1
Continuity mistake: When Kim Neville answers Richard's first question ("Almost a year"), she has her hand in front of her lips in the view from behind, hands on her lap in the fuller view later. This continuity gap keeps happening also at the end of the scene before Fidel arrives. (00:10:30)
Episode #2.1 - S2-E1
Continuity mistake: Louis Nelson's shirt during the first interview with the police pops up fluttering in the wind suddenly between shots when he tells Poole that he was cleaning the barn. (00:11:25)

Episode #2.1 - S2-E1
Other mistake: Dwayne is a veteran police officer who's somehow never ever heard of Luminol (misspelled in close captions, incidentally). (00:14:30)
Episode #2.1 - S2-E1
Character mistake: The clinic who ran the tests for Roger Seymour's brain tumor surely does not employ just brain surgeons, because the spelling in the official report is simply atrocious ("apetite" (twice), "consistant"). (00:21:00)
Episode #2.1 - S2-E1
Revealing mistake: Richard at home is reading a book on slavery. An English book, at least the cover and the big header of the first internal page are in English, and about slavery. But a quick peek before the cut easily reveals that the book is written in French and talks about cocktails. (00:28:10)
Episode #2.1 - S2-E1
Continuity mistake: After Camille shut everyone up with her whistle, Richard says "We'd like to speak with Miss Neville." She has her arms folded, but they are down her sides in the reverse shot. (00:30:00)
Episode #2.1 - S2-E1
Continuity mistake: When Richard gets the proper inspiration to solve the murder thanks to the ribbon Camille dropped on his desk, ribbon and paper are in positions entirely different and under a completely different lighting between close-up and the shot when he picks the ribbon up. (00:33:20)
Episode #2.1 - S2-E1
Continuity mistake: Richard brought Camille to the mill and entrusted his bag to her. As he thinks out loud, he grabs a big iron hammer. Camille changes position moving her hand from the top of the bag to the bottom, and does it again in the close-up a moment later. A few shots later she suddenly is holding the bag by the top again (when he mentions "walking down the track"). (00:34:15)
Episode #2.1 - S2-E1
Continuity mistake: When Dwayne faces the culprit at the end, the handcuffs are above or below his pointed index finger, depending on the angle. (00:46:15)
Answer: Most likely they had only tropical exotic drinks, he wanted an old fashioned English beer.
