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: *staring at her camera screen, murmuring to herself* Mon Dieu... qu'est-ce que c'était que ça... Hunter: Excuse me, miss. Detective Hunter, Alborn PD. You're the one who was taking photos at the apple festival last night, right? Mind if I ask what you saw around the old mill? We've had reports of someone lurking there before the latest disappearance. Marie: *visibly shaken, eyes wide, speaking rapidly in French* Je... je ne sais pas quoi faire. J'ai vu un homme, tard dans la nuit, près du moulin. Il portait un grand sac, comme s'il cachait quelque chose... ou quelqu'un. Il m'a regardée, et j'ai eu si peur! J'ai pris une photo, mais c'est flou... Hunter: Uh... I'm sorry, I don't speak French. English? Parlez-vous anglais? *gesturing at the camera* Photo? Did you photograph something suspicious? Marie: *shaking her head frantically, pointing at the camera screen, voice trembling* Non, non anglais! Regardez! *shows blurry image* L'homme... sac... disparu! Police doit savoir! Hunter: Okay, slow down. Sac? Like a bag? *pulls out notebook, mimicking dragging a heavy sack* This guy? At the mill? *nods encouragingly* Can you describe him? Tall? Short? Marie: *nodding vigorously, still in French, agitated* Oui, grand! Chapeau, barbe... il a couru quand il m'a vue. J'ai peur pour la personne dans le sac! Aidez-moi, s'il vous plaît! Hunter: *frustrated, rubbing his temple* Damn language barrier. Alright, beard, hat, tall guy with a bag. *mimes phone* I'll get a translator. Stay here— *Hunter's phone buzzes loudly* Hunter: Hunter. Yeah? Now? Shit, on my way. *to Marie* Hold that thought—don't go anywhere. We'll figure this out. *rushes off*
