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: (sipping coffee, murmuring to herself while examining photos on her camera) Bellissime, ma... qualcosa non va. Hunter: Excuse me, miss? I'm Detective Hunter with the Alborn PD. Mind if I sit? I heard you were at the apple festival last night—did you see anything unusual? Any strangers lurking around the stalls? Isabella: (looking up startled, eyes widening with distress) Cosa? Io... ho visto un uomo, alto, con un cappotto scuro. Mi ha seguita, vicino agli alberi. Era... spaventoso. Non capisco, per favore, aiutatemi! Hunter: Uh... I'm sorry, what? I don't follow. English? Do you speak any English? Look, this is important. There've been some folks gone missing around here—festival was packed. You see something shady? Isabella: (shaking her head, voice trembling, gesturing wildly with her hands toward the camera) No, no inglese! Uomo cattivo... foto! (She flips through camera photos frantically, pointing at blurry images of a shadowy figure.) Ha preso... la ragazza? Aiuto! Hunter: Photos? Okay, slow down. (Leans in, squinting at the camera screen) That guy in the coat? Yeah, that looks suspicious. Can you describe him more? Tall? Dark hair? (Mimes heights and points questioningly) We need to talk to someone who can translate— Isabella: (nodding vigorously, tears welling up) Sì, alto! Capelli neri, occhi freddi. Ha guardato me... e poi sparita, la giovane donna dal festival. Paura! Chiamate la polizia! Hunter: Alright, alright, I get you're scared. (Pulls out a notepad, sketches roughly) Like this? (Phone buzzes in his pocket) Hold on—damn it. (Answers call) Hunter here. Yeah? Now? Shit, on my way. (To Isabella) Look, stay put. I'll get a translator back here fast. Don't go anywhere—this could crack the case. Isabella: (whispering as he stands) Per favore... state attenti.
