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

Model response

AI
Isabella: Sono turbata e spaventata. Qualcosa di brutto è successo qui durante la Festa delle Mele. Non posso dire di più. Hunter: I don’t speak Italian. Could you tell me in English what you saw? Isabella: C’era una figura alta, avvolta in un cappotto scuro. L’ho vista aggirarsi tra la folla vicino al tendone. Hunter: What did this person do? Did they speak to anyone or come near you? Isabella: Non parlava. Sembrava osservarci da lontano, e quando mi ha fissata, un freddo ha scosso la mia schiena. Hunter: This is worrying. I have to take this call.
