Poirot astounds the police and others by being able to intuit whodunit by what is not present in a crime scene, as much as what is right in front of him. He has an almost instant ability to size up people’s personalities and know whether he wants to interact with them, such as when he tells a man frankly that he will not act as his bodyguard because he “does not like” (or trust) him. Poirot is not at that moment aware of his scandalous history, but senses something amiss with him. SPOILERS. Though warm, interested in people, and usually polite, Poirot also has an objective sense of morality. He grapples with it in solving this case, since it asks him to go against his moral principles and forgive a bunch of murderers, due to the crime they were reacting against being so “heinous” that it gives him second thoughts. Poirot morally judges the victim as reprehensible, and as those responsible for his death in the wrong, but then turns his back on the case and enables them to escape, believing they have avenged the dead woman and her child. His Ti twists the case around and around in his head, unable to reconcile his hunch with the facts, until he finds something, the only thing, that makes sense to him – that they all did it. He uses his Se mostly to gather clues in crime scenes and react in the moment if necessary, but also shows his ability to forward-think in preparation for that (when he plants his cane in the Wailing Wall, knowing someone is going to smack into it and fall in an attempted escape).

Poirot is a perfectionist to the hilt, who has to have his eggs be the exact same size before he will pronounce them edible. He has strong, even rigid at times, moral principles and tells a man to his face he does not care for him, nor have any interest in protecting him on the train. He would much rather sit and read his book. Alone. Yet, a sense of duty and morality drives him, again and again, to accept cases, because he is “needed.” That appeals to his 2 wing’s ego, which prides itself on being useful in society and fixing its ills. It also enables him to have a softer side than some previous Poirot incarnations – he is forgiving of people and their mistakes and makes allowances for their fallible human nature.
