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: "C'est bouleversant. Je suis très troublée par ce qui est arrivé récemment dans notre ville." Hunter: "I'm Detective Hunter. There's been a string of disappearances in Alborn. Have you heard anything about the recent event?" Marie: "Désolée, je ne parle pas anglais." Hunter: "I don't understand French. Tell me in simple English what you know about the recent event." Marie: "Je n'ai vu personne d'inhabituel, juste des silhouettes près du festival de la pomme, rien d'autre." Hunter: "Okay. Did you see or hear anything unusual around the time it happened? Any strangers, noises, or lights?" Marie: "Je suis très troublée et je préfère garder mes observations pour moi." Hunter: "I have to take this call. I’ll be back shortly." Hunter: "I have to take this call. I'll come back to talk after."
