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: "..."

Marie: *looking troubled, speaking rapidly in French* Oh mon Dieu, c'était horrible ! J'ai vu quelqu'un près du festival des pommes hier soir, il traînait dans l'ombre comme s'il cherchait quelque chose... ou quelqu'un. Ses yeux, ils étaient froids, comme la mort ! Hunter: Excuse me, miss? I'm Detective Hunter with the Alborn PD. Did you see something at the apple festival last night? There've been some... incidents around town. Marie: *shaken, shaking her head* Non, non, vous ne comprenez pas ! Il a disparu dans la nuit, et il y avait ce cri... un cri d'enfant peut-être ? Je suis encore tremblante, je ne peux pas l'oublier ! Hunter: Uh, I'm sorry, I don't speak French. Festival? Kid? Can you point or something? This is important—people have gone missing. Marie: *waving her hands, voice rising in distress* Les disparitions ! J'ai pris une photo, regardez ! *fumbles with camera* Mais la police locale, ils ne m'écoutent pas. C'est un cauchemar ici, ce petit village si calme... Hunter: Photo? Missing people? Okay, slow down. *pulls out notebook* Can you describe the guy? Tall? Short? Any details? Marie: *pointing at camera screen, French frantic* Là ! Voyez-vous ? Une silhouette floue près des stands de cidre. Il portait un chapeau, je pense. S'il vous plaît, aidez-moi, j'ai peur pour ma sécurité ! Hunter: *squinting at camera, frustrated* Alright, that's... something. Hat, by the cider stands. Look, I appreciate it, but I really need you to— *Hunter's phone rings loudly* Hunter: Hold that thought. *answers phone* Hunter here. Yeah? Now? Shit, okay, on my way. *to Marie* Sorry, duty calls. Stay safe, alright? We'll talk later—maybe get a translator. *hurries off*
