Other mistake: Poirot, Hastings and The Veiled Lady go upstairs because the lobby is 'too public'. The man spying on them is hiding behind the same newspaper prop used in the previous episode of the season, where Hastings was reading it in Cornwall at the beginning. So must be a pretty old issue now (Peril at End House takes a few days, and they were on holiday). (00:07:40)
Other mistake: The closing credits on the DVD are for another episode, "The Kidnapped Prime Minister." (00:47:15)
Other mistake: Japp manages to coordinate the pincer action of the 3 police cars using a very broad map and no real information about the whereabouts of the suspect. The whole scene is rather silly, it would work in a modern thriller with a GPS, perhaps, not with toy cars and a street map of London.
The Disappearance of Mr. Davenheim - S2-E5
Other mistake: Lowen allows Hastings inside his Bugatti, but then leaves to join a member of his staff who beckoned him. We actually see him in front of the staffer and the person with him. Cue Japp, who has then a little comical interlude with Hastings for about 20 seconds. Cut then to Lowen who.is just now being introduced to the guy he came over to greet. Surely he has not been standing in awkward silence all that time. And even if we assume that this conversation is supposed to happen simultaneously to the Hastings and Japp show, it is half as short, meaning it would have cut into their antics when he ends it by yelling at them. (00:23:15)
The Disappearance of Mr. Davenheim - S2-E5
Other mistake: When Japp and the bobby arrest the pickpocketer, the dialogue says "It was only last week that we put him inside for three months" which obviously does not make sense. In the original story he did the 3 months of jail the year before, and this has to be a flub in the lines of this TV version (it is specified also that he did those in the winter, so the Sergeant can't possibly mean that he was released last week). (00:35:00)
The Adventure of the Cheap Flat - S2-E7
Other mistake: Spying on the Italian embassy from Japp's van, the building has 2 Italian flags of the period. But the rightmost one is mounted upside down, with the crown under the shield instead of the opposite. (00:23:05)
