The Adventure of the Western Star - S2-E9
Continuity mistake: In his preparations for the arrival of his idol, Poirot sets a bunch of flowers with a card ("Mlle. Marie Marvelle"). When we see the bunch later as Poirot has to leave to go to her, the card is absent - but he has not touched the table. (00:03:55 - 00:05:15)

The Adventure of the Western Star - S2-E9
Continuity mistake: Mademoiselle Marvelle outstretches her arm to hand Poirot the menacing message; her hand does not move in the following shot, but when we get back to a full view of Rosalind Bennett, she is holding the card with her arm bent. (00:07:05)
The Adventure of the Western Star - S2-E9

The Adventure of the Western Star - S2-E9
Continuity mistake: Japp shows his documents to the two policemen who caught him lurking in the bushes; when he says "Twigez-vous?" he's holding the card by the corner, while in the reverse shot ("Oh, very sorry, Sir") he's holding it in the middle. (00:25:30)
The Adventure of the Western Star - S2-E9
Revealing mistake: Japp is waiting for Van Braks to make his move, and when he is hopping on a taxi for the airport, he begins to tail him. When the car moves, reflected in the door is a modern No Parking cone in bright yellow (incidentally, they also pass by a parked car with a FUU 692 plate that is a bit too recent for the series, being an Austin Big 7, first produced in 1937). (00:41:05)
The Adventure of the Western Star - S2-E9
Continuity mistake: When Poirot enters the room of Mademoiselle Marvelle after her husband took off for the airport, she opens the door to him holding the door in two contrasting ways (right hand on the side of the door in the first shot, behind the door using the left hand to push it closed in the other). (00:41:35)

Continuity mistake: Japp watches the worker with the flags pass him by while he's leaning his arm on the window. His arm was not there in the shot of the vehicle from behind. (00:45:15)

The Adventure of the Western Star - S2-E9
Factual error: Assuming the episode is in line with the others of the season and it is set in 1935, a few vehicles shown are slightly too recent. The plane waiting for South Africa is a Beechcraft Model 18 (first produced in 1937), the train going to Yardly has a SR Q locomotor first produced in 1938, and the truck that slows Japp down before getting to the airport is a Bedford M-Type, a model first produced in 1939 (the specific one used in this episode is from 1947).
