Quote context

[...]

- That old scoundrel Claudin must have stolen it.

- Why?

- Isn't it obvious?

- Speaking purely as an inspector of the Sûreté, I'm afraid that even the obvious often needs confirmation.

- But as a man, Monsieur Daubert, you can understand that sitting there in the orchestra pit night after night and looking at Christine, Claudin probably fell in love with her.

- You admit that is possible, no?

- Christine, did Claudin ever seek more than a casual acquaintance with you?

- No, never.

- Can you imagine so diffident a lover, monsieur? Claudin was barely 50.

- Well, no doubt he lacked assurance.

- No doubt.

- This is yours, Christine.

- You're giving it to me?

- Yes.

- Well! Then I'll accept it as a gift from both of you.

- Well, I seem to have got the worse of this bargain.
