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: "..."

Isabella: "Buongiorno... sì, ero al festival ieri sera. Ho visto... ho visto quell'uomo, quello con il cappello, litigare con una donna vicino al chiosco delle mele. Sembrava arrabbiato, e poi lei è sparita. Mi ha spaventata." Hunter: "Excuse me, miss. I'm Detective Hunter with the Alborn PD. I understand you're a visitor here—mind if I ask about the apple festival last night? Did you see anything unusual?" Isabella: "Non capisco... inglese? No, solo italiano. Ma era terribile, quella scena... il litigio, e poi silenzio. Ho le foto sul telefono, ma non so spiegare." Hunter: "Italian? Uh, do you speak any English? I'm investigating some... incidents. Festival? Apple? Fight? Did you see a fight?" Isabella: "Sì, fight... lite. L'uomo ha urlato, 'Non dirlo a nessuno!' e lei è corsa via. Io ho scattato una foto, ma ero sola, spaventata. Per favore, aiutatemi a capire." Hunter: "A fight, huh? Okay, that's something. Can you show me the photo? Phone? Camera?" (pauses, mimicking taking a picture) "This might be important. Hold on—" Isabella: "Ecco, guardi... qui, l'uomo con il cappotto scuro. Sembrava sospetto. Ma non so il vostro linguaggio..." Hunter: "Dark coat... suspect. Alright, if you could just—damn it." (phone rings) "Hunter here. Yeah? Now? Shit, on my way. Sorry, miss, duty calls. We'll need to follow up—do you have a name? Isabella? Thanks. Stay safe."
