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: "Je suis troublée et ébranlée. Je regardais mes photos sur mon appareil quand vous vous êtes approché." Hunter: "I don't speak French. Have you heard anything about the recent disappearances in Alborn?" Marie: "Je ne parle pas anglais." Hunter: "Then tell me in any way what you saw." Marie: "J'étais assise ici, à prendre des photos près de la place, quand des silhouettes et une voiture noire ont été vues. Puis tout s'est accéléré et la rue est devenue silencieuse." Hunter: "A car, silhouettes... anything more specific? Time? Location?" Marie: "La lumière autour de la fontaine s'est éteinte juste avant le départ de la voiture." Hunter: "Okay. I think I have something to go on." Hunter: "I have to take this call. I'll come back as soon as I can."
