How Does Your Garden Grow? - S3-E2
Factual error: At the very beginning of the episode, Katrina visits the Soviet embassy. It is written in big letters; "Union of the Soviet Socialist Republic", while the correct official name was "Union of Soviet Socialist Republics." (00:01:45)

Continuity mistake: Miss Barrowby pretends to have just then recognized Poirot, she lowers her left hand, but has it up when he nods to her, and he has his matching hand suddenly higher too. (00:09:00)

Continuity mistake: Once Japp passes him back the seed packet telling him it's empty, Poirot checks it out; in the close-up he's holding the paper in a completely different way (the side instead of the top). (00:11:20)

Continuity mistake: Poirot asks Dr. Sims "So the Delafontaines, they were dependant" etc., the doctor's right hand changes position between shots, and the hand positions keep alternating between the two versions depending on the camera angle (an item suddenly appears in his hand when Miss Lemon mentions the living relatives, too).

Factual error: Poirot and Miss Lemon go to the riding school to meet the solicitor of the deceased. Parked in the road right as the camera pans, and featured for a few seconds, is a car Morris Eight series II, a 1938 model while the episode (as made abundantly clear by the fair invite and banner) is set in 1935.

Other mistake: After Katrina is arrested, Mr. Delafointaine is reading about it on the newspaper. The newspaper is dated Thursday 23rd May 1935. The date is correct, the whole investigation does happen in a day, starting around 10 AM; Poirot is greeted by the couple with "Good afternoon" and to imagine that by the time he gets to their home Katrina's news (complete with picture of the arrest!) is already in a late edition of the newspaper (a local one, at that) is a bit too much of a stretch, with all the steps taken for the investigation, everything in broad daylight. (00:43:20)
Answer: He definitely says "Belgian", but the subtitles get it wrong and show him saying "American."
