Col. Johnny Race: Why doesn't someone murder her.
Hercule Poirot: Well maybe the world's lending libraries will band together and hire an assassin.
Andrew Pennington: What the hell is going on?
Hercule Poirot: We're going through your private papers, sir, isn't that obvious?
Mrs. Van Schuyler: Shut up, Bowers. Just because you've got a grudge against her, or rather her father, no need to be uncivil.
Miss Bowers: Grudge? Melhuish Ridgeway ruined my family.
Mrs. Van Schuyler: Well, you should be grateful. If he hadn't, you would have missed out on the pleasure of working for me.
Miss Bowers: I could kill her on that score alone.
Mrs. Van Schuyler: Come, Bowers, it's time to go, this place is beginning to resemble a mortuary.
Miss Bowers: Thank God you'll be in one yourself before too long you bloody old fossil.
Mrs Otterbourne: Frenchmen aren't afraid of good strong sex.
Mrs. Van Schuyler: You need a nice cool holiday, I was thinking of a trip along the Gobi Desert.
Jim Ferguson: You damn froggy eavesdropper.
Hercule Poirot: Belgian! Belgian eavesdropper.
