You are an expert novel author in the cozy mystery genre. Take the following details about characters/locations/... into account: <character name="Isabella"> Isabella is a 30-year old college student on a study abroad program. Born in Italy, she is fluent in Italian 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 Italian, 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: Isabella 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 Italian, and Hunter looks confused. They talk for a while, until Hunter gets a call and has to leave. Return the dialogue between Isabella and Hunter as a voice sheet: Isabella: "..." Hunter: "..."

Model response

AI
Isabella: "Oh no... non posso credere a quello che ho visto..." Hunter: "Excuse me, miss. Detective Hunter, Alborn PD. You were at the apple festival last night? See anything unusual near the woods?" Isabella: "Un uomo! Alto, con cappuccio... trascinava una ragazza! Ho provato a fotografare, ma era troppo buio! Tremendo!" Hunter: "Whoa, slow down. I don't speak Italian. English? Parla inglese?" Isabella: "No! Solo italiano! La ragazza... sparita! Come gli altri! Devo dirlo a qualcuno!" Hunter: "Disappeared? Like the others? Can you point it out? Show me on your camera?" Isabella: "Sì, la macchina fotografica! Guarda qui... ombre, lotta... polizia, per favore, indagate!" Hunter: "Okay, camera—foto? Let me see those shadows. This could be key to the missing persons case." Isabella: "Esatto! L'uomo aveva un tatuaggio sul braccio... un serpente? Aiutatemi, ho paura!" Hunter: "Tattoo? Snake? That's a lead. Stay here, I'll—" *[phone rings]* Hunter: "Hunter here. Yeah? Another one? On my way—five minutes out." Isabella: "Aspetta! Non andare, devi vedere le foto!" Hunter: "Gotta go. Grazie—uh, thank you. We'll talk soon."
