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: *(murmuring to herself, scrolling through her camera)* "...non è possibile. L'ho visto. So che l'ho visto." Hunter: "Excuse me, miss? Mind if I ask you a few questions? Detective Hunter, Alborn PD." *(pulls out a small notepad)* "You were near Birch Street last night, weren't you? Around the time of the disturbance?" Isabella: *(looking up, startled, eyes wide)* "Oh— mi scusi, io... non parlo inglese. Non capisco." Hunter: "...Right. Okay. You don't— you don't speak English." *(sighs, rubs the back of his neck)* "Look, I just need to know what you saw. Last night. The lights, the noise—anything." Isabella: *(voice trembling, gesturing toward her camera)* "Ho delle foto. Guardi— guardi qui. C'era qualcuno tra gli alberi, e poi... poi è sparito. Sparito nel nulla! Le giuro, non sto mentendo." Hunter: "Whoa, whoa, slow down. I'm not—" *(leans in, squinting at the camera screen she's thrusting toward him)* "Is that... a photo? You got a photo of something?" Isabella: *(nodding rapidly, near tears)* "Sì! Sì, esatto! Ecco, lo vede? Quella figura, lì in fondo. Aveva qualcosa in mano. E io ho avuto così tanta paura..." Hunter: "Hey, easy. It's okay. I can see you're shaken up. I just—God, I wish I had a translator right now." *(studies the image, jaw tightening)* "That... that actually might be something. Can I get a copy of this?" Isabella: *(pressing the camera to her chest protectively, then softening)* "Lei mi crede? Davvero? Nessun altro mi ascolta. Pensano tutti che io sia pazza." Hunter: "I don't understand a word you're saying, but I think we both saw the same problem in this town." *(his phone buzzes; he glances at it, expression hardening)* "Hold that thought." Isabella: *(watching him answer, anxious)* "Cosa succede? È un'altra persona scomparsa?" Hunter: *(into phone)* "Hunter. ...When? ...All right, I'm on my way." *(stands abruptly, pocketing the notepad)* "I have to go. Listen—" *(points at her, then the camera, then mimes typing)* "Stay here. Photos. I'll come back. Okay? Don't go anywhere." Isabella: *(confused, reaching out)* "Aspetti! Dove va? Non mi lasci così, la prego—" Hunter: "I'm sorry, I really am. I'll—" *(already backing away toward the door)* "I'll find someone who speaks Italian. I promise. Just stay safe." Isabella: *(calling after him, quietly, as the door closes)* "...Per favore, torni. Non so a chi altro rivolgermi."
