“Yes, yes-you will give him the earth-because you love him. Love him too much for safety or for happiness. But you cannot give to people what they are incapable of receiving.”

“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....”

“The happy people are failures because they are on such good terms with themselves they don't give a damn.”

“I know when a couple are really in love with each other. And by that I do not mean just sexually attracted. There is too much talk about sex, too much attention is paid to it. I do not mean that anything about sex is wrong. That is nonsense. But sex cannot take the place of love, it goes with love, but cannot succeed by itself.”

“It is a curious thought, but it is only when you see people looking ridiculous that you realize just how much you love them. ”

“You tell your lies and you think nobody knows. But there are two people who know. Yes- two people. One is le bon Dieu - and the other is Hercule Poirot”

“Trains are relentless things, aren't they, Monsieur Poirot? People are murdered and die, but they go on just the same. I am talking nonsense, but you know what I mean.""Yes, yes, I know. Life is like a train, Mademoiselle. It goes on. And it is a good thing that that is so.""Why?""Because the train gets to its journey's end at last, and there is a proverb about that in your language, Mademoiselle.""'Journey's end in lovers meeting.'" Lenox laughed. "That is not going to be true for me.""Yes--yes, it is true. You are young, younger than you yourself know. Trust the train, Mademoiselle, for it is le bon Dieu who drives it."The whistle of the engine came again."Trust the train, Mademoiselle," murmured Poirot again. "And trust Hercule Poirot. He knows.”
