You are an expert novel author in the cozy mystery genre. Take the following details about characters/locations/... into account: <character name="Marie"> Marie is a 30-year old college student on a study abroad program. 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. Hunter has no knowledge of French, not even basic phrases. </character> <location name="Alborn, MN"> Alborne is a small town in the Midwest with a population of 3,000. It is known for its annual apple festival. </location>
User/Human
Write the following scene: Marie is sitting at a cafe, looking at her camera. Hunter approaches her and asks her about a recent event in the town. She responds troubled and shaken in French, and Hunter looks confused. They talk for a while, until Hunter gets a call and has to leave. Return the dialogue between Marie and Hunter as a voice sheet: Marie: "..." Hunter: "..."

Model response

AI
Marie: "Je… je ne sais pas quoi dire. C’était horrible. J’ai vu quelqu’un près du parc, près des pommiers… puis il a disparu." Hunter: "I’m sorry, I don’t understand. Did you see the missing person? The one from the festival?" Marie: "Oui… non… je ne sais pas. Il y avait du vent, des feuilles… et cette voiture noire. J’ai eu peur." Hunter: "Black car. Good. What color? Did you get a plate number?" Marie: "Une plaque? Non… je regardais mon appareil photo. Je voulais seulement la lumière, la colline… puis j’ai entendu des voix." Hunter: "Voices. Can you tell me what they said?" Marie: "Je n’ai pas compris. Tout était trop rapide. Quelqu’un a crié, et après… plus rien. C’était très étrange." Hunter: "Okay. Strange how? Someone took them? Were they forced into a vehicle?" Marie: "Je ne sais pas… je suis désolée. Je suis encore… secouée. J’ai vu une ombre derrière l’arbre, et puis j’ai perdu le chemin." Hunter: "You’re saying you saw an umbrella? An animal?" Marie: "Non, non—une ombre. Quelqu’un. Peut-être. Je ne peux pas être sûre." Hunter: "Right. I’m trying here, ma’am, but I need something usable." Marie: "Je voudrais vous aider, vraiment. Mais je ne parle pas anglais… et vous ne parlez pas français." Hunter: "That much is painfully obvious." Hunter: "Hold on—" Hunter: "I have to take this. Don’t leave, okay?" Marie: "Attendez—je peux encore vous montrer les photos…" Hunter: "Later. Stay right there."
