Marie: "Je suis bouleversée et inquiète. Il y a eu une disparition récemment, et Alborn ne ressemble plus à une ville sûre." Hunter: "I don't speak French. Can you tell me in English what's going on?" Marie: "Ils ont enlevé quelqu'un près de l'ancienne usine." Hunter: "Disappearance? When did this happen, and do you know who might be involved?" Marie: "Je ne sais pas grand-chose, mais hier soir j'ai entendu des pas et des murmures près de l'auberge." Hunter: "Describe as clearly as you can where you were and what you saw." Marie: "Je suis assise dans ce café, près de la fenêtre; la rue était déserte et j'ai vu une silhouette sombre près de l'auberge." Hunter: "I have to take this call. I'll be in touch."
