- Captain Hastings: [referring to marriage] You ever thought about it?
- Hercule Poirot: In my experience, I have known of five cases of women murdered by their devoted husbands.
- Captain Hastings: Yes?
- Hercule Poirot: And twenty-two husbands murdered by their devoted wives. So thank you, non. The marriage, it is not for me.
- [last lines]
- Hercule Poirot: You will keep it, I hope. Something to remember me by.
- Countess Vera Rossakoff: Oh... I won't forget you.
- [kisses his head]
- Countess Vera Rossakoff: Hercule.
- Hercule Poirot: Nor I you... Countess.
- Countess Vera Rossakoff: [as the train pulls away] Au revoir.
- Captain Hastings: So why did you go back into the house?
- Mr Johnstone: The call of nature, if you must know.
- Captain Hastings: Were there any witnesses?
- Countess Vera Rossakoff: So, you are saying the police cannot solve it because they're too English.
- Hercule Poirot: Or because the culprit, he is not English enough.
- Hercule Poirot: One can always tell when the summer, it is arrived.
- Captain Hastings: It's in the air, eh?
- Hercule Poirot: No, Hastings, it is in the speed of your driving!
- Hercule Poirot: When was this last robbery?
- Captain Hastings: Three days ago.
- Hercule Poirot: Three days! But it is too late. It is better to strike while the metal is warm, yes?
- Chief Inspector Japp: So what do you think, Poirot?
- Hercule Poirot: I think that it is strange. The glove and the cigarette case, it is as you might say the double clue.
- Captain Hastings: Twice as much for us to work on.
- Hercule Poirot: It is too much, Hastings, too much.
- Captain Hastings: Oh, I hadn't thought of that.
- Hercule Poirot: If you are to be Hercule Poirot, you must think of everything.
- Hercule Poirot: We wait. Already the thief is planning his next crime. And the next one - it will be his last.
- Hercule Poirot: Madam, you are the most remarkable, the most unique woman that I have ever met. But also...
- Countess Vera Rossakoff: Opposites.
- Hercule Poirot: C'est ca. You must continue your work and I must continue mine. But not in the same country.
- Hercule Poirot: Countess, please allow me to introduce two colleagues of mine. Monsieurs Redfern and Blake.
- Blake: Good evening, ma'am.
- Hercule Poirot: They are, like myself, private detectives.
- Countess Vera Rossakoff: Do you really think I need an escort?
- Hercule Poirot: No, no, no. They are for your protection. During your short visit in England, there have been four very clever robberies. I would not wish you to be involved in a fifth.
- Countess Vera Rossakoff: Of course.
- Countess Vera Rossakoff: I had a house like this once in Petrograd. First the house - then a wing in the house - then a room in the wing - and now nothing.
- Hercule Poirot: But that does not make you the thief, madame.
- Countess Vera Rossakoff: No. Life itself is the thief. It has taken everything I had.
- Hercule Poirot: Eh bien, comtesse, tomorrow I will take you to the Tate Gallery to see the collection of Turners.
- Countess Vera Rossakoff: But I find these expressionist painters so exciting. Don't you, Hercule?
- Hercule Poirot: In part, yes. You know, I do not believe that there is anyone of my acquaintance who calls me by that name.
- Countess Vera Rossakoff: Oh, I'm so sorry. Excuse me.
- Hercule Poirot: Madame.
- [first lines]
- Receptionist: Good evening, Countess. It's an honour to have you with us again. Your usual suite is ready.
- Captain Hastings: Suppose he, uh... Poirot and the countess...
- Miss Lemon: He wouldn't... Would he?
- Captain Hastings: I don't know. I've never seen him like this before.
