Born in France, she is fluent in French and does not yet know any English. She enjoys landscape photography and is always seen with her camera. </character> <character name="Hunter"> Hunter is a 35-year old detective who is investigating a series of mysterious disappearances in the small town of Alborn, MN. He is a former marine and has a no-nonsense attitude.

It is known for its annual apple festival. </location>
User/Human

Model response

AI
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."
