- Captain Arthur Hastings: I just wondered if you were having problems sleeping.
- Hercule Poirot: So you awaken me to inquire? That is friendship indeed, Hastings.
- Hercule Poirot: Hastings, a favor. Whatever I should say, you are to nod in agreement.
- Captain Arthur Hastings: Did I ever do otherwise, Poirot?
- Hercule Poirot: But you and I, we know, Bob, one does not have to speak in order to tell. And you will tell to me all, in your own good time.
- Hercule Poirot: You forgot the Sisters Tripp.
- Captain Arthur Hastings: Oh those two? They're batty, yes, but not murderers surely?
- Hercule Poirot: What is murder but a kind of madness, mon ami?
- Captain Arthur Hastings: Marvelous view over here, Poirot. Come and take a look.
- Hercule Poirot: [as he and the fox terrier sit] No. We will take your word for it.
