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: *sitting at the cafe table, fiddling with her camera lens, glancing nervously around the quiet Alborn street* Hunter: *approaching the table, flashing his badge subtly* Excuse me, miss. I'm Detective Hunter with the Alborn PD. Mind if I ask you a few questions? We're looking into that disappearance from the apple festival last weekend—the one with the vendor who vanished. Did you see anything unusual that night? Maybe with your camera? Isabella: *looking up startled, her hands trembling slightly on the camera* Io... io ho visto qualcosa di strano. C'era un uomo, vicino al chiosco delle mele, parlava con qualcuno nell'ombra. Sembrava spaventato, poi è scomparso. Non riesco a togliermelo dalla testa! Hunter: *blinking, tilting his head* Uh... sorry, what? I didn't catch that. You speak English? Can you repeat it slower? This is important—anything about the festival? Isabella: *shaking her head, voice rising with agitation, gesturing wildly at her camera* No, no inglese! Ho foto... ombre, luci strane. Qualcuno lo ha preso! Per favore, aiutatemi a capire, è orribile! Hunter: *frowning deeply, rubbing his chin, clearly frustrated but trying to stay calm* Okay, okay, slow down. Foto? Is that... pictures? You took photos? *mimes taking a picture* Can I see? Show me the camera? Isabella: *nodding vigorously, pulling up photos on her camera screen, pointing at blurry shadows* Sì, sì! Qui, guarda—l'uomo sparisce. Ombre... movimento. Ho paura, detective. Qualcun altro? Hunter: *leaning in to peer at the screen, squinting* Huh. Yeah, that's... shadowy. Looks like it could be something. *straightens up, pulling out a notepad* Alright, if you could just—wait, damn it. *his phone buzzes insistently* Hold on, I gotta take this. *steps away briefly* Hunter here... Yeah? Now? Shit, alright, on my way. Isabella: *watching him anxiously* Aspetta... detective? Hunter: *pocketing his phone, giving her a nod* I'll be back. Don't go anywhere—we need to figure this out. Stay safe. *hurries off toward his car*
