“Difficulties are made to be overcome ~ Miss Felicity Lemon, Agatha Christie's Poirot: The Plymouth Express”

“Hercule Poirot: I am an imbecile. I see only half of the picture. Miss Lemon: I don't even see that.”

“Det kan du stole på. Liker du detektivfortellinger? Det gjør jeg. Jeg leser alle sammen, og har navnetrekkene til Dorothy Sayers og Agatha Christie og Dickson Carr og H.C. Bailey.”

“About Miss Debenham," he said rather awkwardly. "You can take it from me that she's all right. She's a pukka sahib."What," asked Dr. Constantine with interest, "does a pukka sahib mean?""It means," said Poirot, "that Miss Debenham's father and brothers were at the same kind of school as Colonel Arbuthnot was.""Oh!" said Dr. Constantine, disappointed. "Then it has nothing to do with the crime at all.""Exactly," said Poirot.”

“Poirot, watching him, felt suddenly a doubt--an uncomfortable twinge. Was there, here, something that he had missed? Some richness of the spirit? Sadness crept over him. Yes, he should have become acquainted with the classics. Long ago. Now, alas, it was too late....”

“If you are to be Hercule Poirot, you must think of everything.”
