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

Marie: "Bonjour... Oh, le festival d'hier soir? C'était affreux. J'ai vu un homme... il se disputait avec quelqu'un près des pommiers, et puis... il a disparu dans l'ombre. J'ai pris une photo, mais je tremble encore." Hunter: "Excuse me, miss. I'm Detective Hunter with the Alborn PD. You're Marie, right? The one who was taking photos at the apple festival last night? Did you see anything unusual—a argument, maybe, or someone who seemed out of place?" Marie: "Non, non, je ne comprends pas... L'homme, il criait en anglais, je pense. La femme avec lui... elle avait l'air effrayée. Et maintenant, avec ces disparitions en ville... Mon Dieu, et si c'était lié? J'ai peur de rester ici toute seule." Hunter: "Uh... photos? Festival? Argument?" (pausing, looking confused and gesturing toward her camera) "Can you... show me? English? Parlez-vous anglais?" Marie: "Photos? Oui, j'ai mon appareil... Regardez, voilà. (shows camera screen) Mais c'est flou, il faisait sombre. S'il vous plaît, dites-moi que vous enquêtez là-dessus. Je ne sais pas quoi faire, je suis si secouée." Hunter: "Whoa, hold on—that looks like it could be important. The blurry figure in the background... (leaning in, then pulling back) Damn, if only we could talk this through properly. Is there anyone who can translate? This might connect to the missing persons cases." Marie: "Traduire? Je ne parle que français. C'était près du stand aux tartes aux pommes. L'homme a poussé la femme, et elle a crié... Puis plus rien. (gesturing animatedly, voice trembling) Aidez-moi, s'il vous plaît!" Hunter: "Okay, okay, slow down. Tarts? Push? (miming a push, nodding) Yeah, I get that much. Look, I appreciate you trying. If you can come down to the station later with that camera—" (Phone rings) Hunter: "Hold that thought—sorry, that's my partner. I gotta take this. Stay safe, alright? We'll figure this out." (stands and answers the phone, walking away) "Hunter here. What's the update on the latest sighting?"
