Do you know which Hogwarts house does Poirot belong to? Gryfindor, Hufflepuff, Ravenclaw, or Slytherin?
Hello! I’d put Poirot into Ravenclaw (intelligence, wit, wisdom, cleverness, learning, individuality, originality), same with Miss Lemon and Ariadne Oliver. They all fit Ravenclaw’s motto, “Wit beyond measure is man’s greatest treasure.” Ravenclaw welcomes eccentric and unique people who think outside the box, and they can be outspoken and blunt. The traits fit Poirot, Miss Lemon and Mrs Oliver perfectly.
Captain Hastings and Inspector Japp I see as Gryffindors (courage, chivalry, determination, nerve). They’re men of action, and they’re both brave and true. Japp is a little trickier to sort into a house because he is an intelligent policeman, just not on Poirot’s level, but this is an unfair comparison because no one can match Poirot as a detective. Japp (especially the ITV version with Suchet) has the traits of both Gryffindor and Ravenclaw. He’s a Gryffinclaw to me.
Thank you for your lovely ask! :D
