* In the 2010 adaptation, Mary Debenham's (understandably) distraught reaction to witnessing the stoning is likely not just the result of culture shock. [[spoiler: It's more than likely a result of having been badly beaten herself during the kidnapping, to the point of sustaining permanent nerve damage. No wonder she would be upset upon witnessing such an act of violence against a woman.]]

* Possibly a marginal example, but Poirot must have realized something was up right at the beginning. When [=MacQueen=] was informed of [[spoiler:Ratchett's true identity]], he reacts with shock and anger, despite his father having been the District Attorney for the case. If the case had made that much of an impression on him, wouldn't he have recognized his employer for who he was?

** A single person can't be judge, jury, and executioner. [[spoiler: A jury has twelve members.]]

* Poirot reiterates many times in other books that the reason he never lets a murderer get away with it, however despicable the victim, is that once someone has taken it upon themselves by their own judgment to act as judge, jury, and executioner they become too dangerous to continue in society. In this book, [[spoiler: he lets the murderers go, not only because of how much of a monster the victim was and because the wronged parties had already ''tried'' to seek justice through legal means and been bitterly let down, but also because they judged and acted as a large group rather than as individuals and hence would not be likely to form a habit of murder in the future.]]

* In the 1974 ''{{Murder on the Orient Express}}'', every time Poirot finishes questioning a suspect, Bianchi (I think) says "It was (her/him)! (He/she) did it!" [[spoiler: He's right, of course, every time.]]

* Nearly every one of the suspect utters some kind of mistrustful, xenophobic remark in passing -- "That's the worst thing about Americans, they're so sentimental" -- "I normally don't like them Britishers" -- passengers constantly reduce one another to their nationality. But in fact, [[spoiler: everyone is working together, regardless of what country they come from, to eliminate a common enemy. This is actually a calculated move to keep anyone from figuring out they had all been part of the same household, and as close as could be despite most of them not actually being related.]]

* Poirot referring to the Americans as subjects rather than citizens makes a lot more sense when you remember the Belgians have a king, and that Poirot is famous for his ObfuscatingStupidity FunnyForeigner routine.

* In the book, when they learn the victim was repeatedly stabbed, Monsieur Bouc immediately labels it a crime of passion and says that the murderer must be a woman. Actually, [[the crime was ruthlessly planned in advance, but it was a woman who did all the planning and organizing.]] Well played, Agatha.
