- Dr. Lutz: May I ask you something? Why do you insist on referring to yourself in the third person? It is intensely irritating!
- Hercule Poirot: Because, Doctor Lutz, it helps Poirot achieve a healthy distance from his genius.
- Dr. Lutz: Ha, you French! You make me scream with laughter.
- Hercule Poirot: I am glad, but also Belgian.
- Dr. Burton: What you need, my dear fellow, is another case. Preferably one that puts your life in danger.
- Hercule Poirot: That is your advice most considered, is it?
- Dr. Burton: It's cost you ten guineas, so I suggest you act on it.
- Inspector Lementeuil: Put down the gun.
- Dr. Lutz: This is not a gun! It's an objective correlative!
- Inspector Lementeuil: Put down the objective correlative.
- Katrina: And what are your "requirements", monsieur?
- Hercule Poirot: *Time*, mademoiselle. Time is all that is required by Poirot.
- Hercule Poirot: You look well, Countess.
- Countess Rossakoff: Well?
- Hercule Poirot: Oui.
- Countess Rossakoff: Hercule, such insipidity. At the very least I want to look like a goddess, one of the better ones.
- Hercule Poirot: Oui.
- Countess Rossakoff: Of course I look well. It is my life of unrelenting virtue. My life of crime is largely over.
- Schwartz: A, a point of information. I am advised that a small quantity of snow has fallen in the tunnel of the funicular. The, the workmen are attending to the obstruction, and it'll soon be clear.
- Hercule Poirot: S'il vous plaît, monsieur, how soon?
- Schwartz: Oh, tout suite, monsieur. Very soon, very soon. Within a couple of days for certain.
- Countess Rossakoff: Ah, so we a trapped in this preposterous place.
- Schwartz: It is a large... small quantity of snow, but don't be despondent. It will be gemütlich up here. We have a food, we have a wine. We shall be... ah... What is the phrase?
- Countess Rossakoff: Demented with boredom.
- Schwartz: Ah, cosy! We shall be most cosy.
- Alice Cunningham: With the killer in the premises.
- Countess Rossakoff: Ah, yes.
- [giving a box]
- Countess Rossakoff: These are for you.
- Hercule Poirot: For me? Ah.
- [looking at the cufflinks]
- Hercule Poirot: These a beautiful.
- Countess Rossakoff: I have from time to time lost my money and my dignity, Hercule. I never lost my taste.
- Hercule Poirot: But...
- Countess Rossakoff: No, I did not steal them. My father wore them when we fled Petersburg.
- Hercule Poirot: Merci beaucoup.
- Dr. Lutz: Monsieur Poirot! Let me be absolutely clear. I cannot permit you to interfere with my patient.
- Hercule Poirot: Doctor Lutz. Are you an admirer of Nietzsche?
- Dr. Lutz: All Austrians are not Nazis, Monsieur Poirot.
- Hercule Poirot: You think that I try to trap you?
- Dr. Lutz: Naturally, it's your métier. Who is employing you and what do you want from my patient?
- Hercule Poirot: In this case, I am engaged by Monsieur Ted Williams, and what I require from Mademoiselle Samoushenka is to return her maid Nita.
- Dr. Lutz: I've genuinely no idea what you're talking about.
- Hercule Poirot: Nita, the servant maid impeccable. Monsieur Ted Williams, the lover most ardent and full of chivalry.
- Dr. Lutz: You speak to me in archetypes. All this is very Jung. Nobody with intelligence credits Jung.
- Hercule Poirot: What is wrong with the lady in Room 16?
- Dr. Lutz: Pah! You French, you make me scream with laughter.
- Hercule Poirot: Hmm, I am glad... but also Belgian.
- Dr. Lutz: You cannot expect me to compromise my client confidentiality. Are you mad?
- Hercule Poirot: No, Doctor, but neither is Katrina Samoushenka.
