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: *sitting at the cafe table, fiddling with her camera lens, looking pensive* Hunter: Excuse me, miss. I'm Detective Hunter with the Alborn PD. Mind if I ask you a few questions? Were you at the apple festival last weekend? Did you see anything unusual—anyone acting suspicious near the orchards? Marie: *looks up startled, her eyes wide and troubled, setting the camera down with shaky hands* Oh... je... je ne comprends pas. C'était horrible, monsieur. J'ai vu quelqu'un... une ombre dans les arbres, près du festival. Une femme a disparu, n'est-ce pas? J'ai pris des photos, mais... elles sont floues. J'ai peur. Hunter: *frowning in confusion, leaning in slightly* Uh, sorry? I don't follow. Festival? Disparu? You speak English? Look, I'm investigating some missing persons cases. Anything you saw could help. Marie: *shaking her head, voice trembling, gesturing vaguely toward her camera* Non, non... pas d'anglais. L'ombre... elle bougeait vite. Comme si elle traquait quelqu'un. La police... vous devez vérifier les bois derrière le stand de pommes. S'il vous plaît, c'est important! Hunter: *rubbing his temple, trying to parse her words, no-nonsense tone softening a bit* Okay, slow down. Bois? That's... trees? You saw something in the woods? *mimes taking a photo* Pictures? Can I see? Marie: *nods frantically, pulling up photos on her camera screen, pointing at blurry shapes* Oui, ici! Regardez... une silhouette, la nuit tombante. J'ai entendu des cris, mais personne ne m'a crue. C'est lié aux disparitions, je le sais! Hunter: *squinting at the screen, nodding slowly* Alright, this is something. Shadowy figure, cries—got it, sort of. *pulls out a notepad, sketching roughly* Near the apple stand? You're sure? Marie: *biting her lip, voice hushed and shaken* Absolument. Mais... je ne veux pas d'ennuis. Les gens ici regardent bizarrement les étrangers. Aidez-moi, s'il vous plaît. Hunter: *sighing, still puzzled but determined* I'll look into it. Stay safe, okay? If you remember more— *phone buzzes in his pocket* Damn. Hold on. *answers the call* Hunter here. Yeah? Now? Alright, I'm on my way. *to Marie, standing up* Gotta go—emergency. Thanks for the tip. We'll talk again. Marie: *watching him leave, whispering to herself* Au revoir... soyez prudent.
