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: "Oh, mio Dio, è stato terribile! Ho visto quell'uomo sparire nel bosco, con la nebbia che lo inghiottiva... Non so cosa fare!" Hunter: "Excuse me, ma'am? I'm Detective Hunter with the local PD. I noticed your camera there—mind if I ask if you've seen anything unusual around the apple orchards lately? We've had some folks go missing." Isabella: "Non capisco... Parla italiano? Ero lì con la mia macchina fotografica, e ho scattato foto, ma poi... quell'ombra! Era come un fantasma nel festival delle mele!" Hunter: "Whoa, slow down. Italian? Uh, I don't speak that. Did you say something about photos? You got pictures of the festival? Maybe something related to the disappearances?" Isabella: "Le sparizioni? Sì, sì! Ho visto una persona... svanire! Ecco, guardi le foto!" (She gestures frantically at her camera, holding it up.) Hunter: "Photos? Okay, that I get. Let me see... Wait, these are from the woods near the orchard? That shadow—looks suspicious. Hang on, you witnessed one of the vanishings?" Isabella: "Non so l'inglese! Chiami qualcuno che parli italiano, per favore! Sono spaventata!" Hunter: "Alright, alright, I think you're saying you're scared. Don't worry, we'll figure this out. Maybe I can get a translator over here—" (Hunter's phone rings.) Hunter: "Hold that thought. This is Hunter... Yeah, another lead? I'm on my way. Sorry, ma'am, duty calls. Stay put—I'll send someone back for those photos!"
