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 troubled, shaking slightly as she clutches her camera* Je... je ne sais pas quoi faire. J'ai vu quelqu'un près du festival des pommes hier soir. Il y avait une dispute, et puis... elle a disparu. C'était horrible, comme dans un cauchemar. Hunter: Excuse me, miss. I'm Detective Hunter with the Alborn PD. Mind if I ask—did you see anything out of the ordinary at the apple festival last night? Folks have been going missing, and we're talking to everyone. Marie: *eyes widening, voice trembling* Non, non, vous ne comprenez pas ! La femme... elle criait en français, et l'homme l'a traînée vers les arbres. J'ai pris une photo, mais je tremble tellement... Et si c'était lié aux autres disparitions ? Hunter: Uh... I'm sorry, I didn't catch that. Do you speak English? This is important—anything about the festival? A woman, you said? *frowning in confusion, leaning in slightly* Marie: *frustrated and shaken, gesturing vaguely toward her camera* Anglais ? Non, je suis désolée. Écoutez, la police doit savoir ! Il portait un chapeau, et il sentait l'alcool. S'il vous plaît, aidez-moi à expliquer... Hunter: Okay, slow down. Photo? You have a photo? *trying to mimic her gestures, pulling out his notebook* Hat... alcohol? Can you show me? *glancing around the cafe, clearly puzzled* Marie: *nodding urgently, fumbling with her camera but still distressed* Oui, photo ! Regardez ici... *shows a blurry image on the screen* C'est flou, mais c'est lui. Je suis effrayée, monsieur. Alborn semble si paisible, mais il y a du danger. Hunter: *squinting at the camera screen* Alright, that's... something. Smells like we're onto— *phone buzzes loudly; he checks it* Damn. This is Detective Hunter. Yeah, got a lead—wait, what? Another one? I'm heading over now. *stands up abruptly* Sorry, miss, I gotta run. Stay safe— we'll follow up on that photo soon. *hurries off*
