The Mysterious Affair at Styles - S3-E1
Continuity mistake: Mrs. Inglethorp's death happens with her having a much messier hair and the neck tilted to an angle in the wider shot, compared to the close-up on Gillian Barge. (00:30:00)
The Mysterious Affair at Styles - S3-E1
Continuity mistake: Poirot locks the document case in a close-up. The shadow on the case is at the center of the object, but in the wider shot it is projected entirely on the left side. (00:38:15)
The Mysterious Affair at Styles - S3-E1
Continuity mistake: The larger broken porcelain pieces Poirot is examining in front of the fireplace change place between shots. (00:39:45)
The Mysterious Affair at Styles - S3-E1
Continuity mistake: About the burnt will, the lawyer asks the obvious question to John Cavendish "Are you so sure it's a coincidence?" He's holding in his raised left hand a sheet. Next shot and he has both hands down on the desk. (00:48:55)
The Mysterious Affair at Styles - S3-E1
Continuity mistake: At the hearings, the doctor is on the stand and says "There was no strychnine in it." Mr. Wells closes his fountain pen. But then in the next shot he holds it in his hand. (00:52:40)
The Mysterious Affair at Styles - S3-E1
Continuity mistake: The coroner asks Mary to tell everyone about the quarrel. Frontal shot of Mr. Wells; he is pointing his hand with the spectacles at a certain height. Reverse shot; the hand is lower, resting on the other hand, and only then he raises it to the same level as it was in the other shot. (00:53:40)
The Mysterious Affair at Styles - S3-E1
Continuity mistake: When Hastings tries the fake beard on, it sticks past his fingertips more in the shots from behind than on the front. (01:09:15)
The Mysterious Affair at Styles - S3-E1
Continuity mistake: Cynthia is sobbing with Hastings, and he asks her to marry him. The handkerchief in her hand changes position between shots (particularly easy to spot when you look at the black band). (01:13:05)
The Mysterious Affair at Styles - S3-E1
Continuity mistake: Poirot is concentrating in London, making a house of cards. When he says "I steady my nerves, that is all", the 6 of hearts can be seen in his right hand, and he sets it as the diagonal piece. Cut to Hastings, and then Poirot supposedly still has the same house in front of him...but it is not. Where the 6 of hearts was, there is now a 6 of spades, and the whole castle is different, with the cards pulled tighter together. Later he rebuilds the house, and he sets horizontally in the close-up a 5 of spades, which turns into the 2 of spades immediately after. (01:19:40)
The Mysterious Affair at Styles - S3-E1

How Does Your Garden Grow? - S3-E2
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)
How Does Your Garden Grow? - S3-E2
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)
How Does Your Garden Grow? - S3-E2
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). (00:26:30)
The Million Dollar Bond Robbery - S3-E3
Continuity mistake: In the cabin of Mr. Ridgeway, Poirot approaches the portmanteau. In the close-up the tie covers completely the lock before Poirot pushes it aside with his cane, but in the wider shot part of it was already visible, uncovered. (00:24:25)
The Million Dollar Bond Robbery - S3-E3
Continuity mistake: When Poirot receives his platter of buttered brains, the delicacy that makes Hastings queasy is turned a different way in each shot (easy to tell from the asparagus). (00:28:05)

Continuity mistake: After Ridgeway puts down his Queens High, his hand is hovering slightly on the table, but at the cut it is arched, fingers pointing on the table. (00:28:55)
The Million Dollar Bond Robbery - S3-E3
Continuity mistake: When Poirot says "I'm sorry" to the culprit, he has the hand on the shoulder of his accomplice. Her hair is on and off that shoulder in a blink. (00:48:35)
Continuity mistake: At the hotel, the Count is checking in. Behind him by the revolving doors you can see three people having a conversation, with one being a woman wearing a distinct floral dress and brown stole. He steps away from the concierge and the same woman is having a chat in a different part of the hotel, right part of the frame. (00:03:30)
Continuity mistake: Hastings and Poirot are talking about the optimist friend. Once Hastings says "It bucketed down", he's holding the newspaper, and it stays pretty firm. Miss Lemon knocks, and the newspaper is now folding at the upper corner. (00:06:45)
