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: (looking up from her camera, voice trembling in French) Oh mon Dieu, c'était horrible... Cet homme, il a simplement disparu dans la brume près du lac. J'ai pris une photo, mais... je suis si effrayée! Hunter: Excuse me, ma'am? I'm Detective Hunter. I was wondering if you've seen anything unusual around town lately—maybe related to the recent disappearances? Folks have been going missing without a trace. Marie: (shaking her head, still in French, gesturing wildly with her hands) Non, non! Vous ne comprenez pas! Il y avait des ombres, des bruits étranges... J'ai vu quelque chose d'anormal lors du festival des pommes. Aidez-moi, s'il vous plaît! Hunter: Whoa, slow down there. I'm sorry, I don't speak... is that French? Look, if you witnessed something, can you point it out or show me on your camera? We need to get to the bottom of this. Marie: (frustrated, pointing at her camera and speaking faster in French) Regardez! Voici la photo. L'homme avec le chapeau rouge... il était là, puis plus rien. C'est comme un fantôme dans cette petite ville! Hunter: Okay, the photo—yeah, I see it. That guy looks familiar. One of the missing persons? Hang on, let me try to... uh, par-lay voo? Darn it, that's all I got. Can you draw a map or something? Marie: (sighing deeply, still in French, her voice shaky) Un carte? Oui, mais c'est dangereux. La forêt près d'Alborn... des secrets sombres. Soyez prudent, détective. Hunter: Forest? Danger? Alright, I think I get the gist. Thanks for your help—stay safe out here. (phone rings) Hold on... Yeah, this is Hunter. What? Another disappearance? I'm on my way. Sorry, ma'am, gotta run!
