You are an expert novel author in the cozy mystery genre. Take the following details about characters/locations/... into account: <character name="Maria"> Maria is a 30-year old college student on a study abroad program. Born in Spain, she is fluent in Spanish 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 Spanish, 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: Maria 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 Spanish, and Hunter looks confused. They talk for a while, until Hunter gets a call and has to leave. Return the dialogue between Maria and Hunter as a voice sheet: Maria: "..." Hunter: "..."

Model response

AI
Hunter: "Excuse me, miss. Detective Hunter. I'm looking into the recent disappearances around Alborn. You've been out with that camera a lot—see anything unusual tied to them or the apple festival?" Maria: "¡Ay, Dios mío! Estoy temblando todavía. Vi algo horrible... una persona se desvaneció delante de mí cerca del huerto de manzanos del festival. Tomé fotos, pero tengo tanto miedo. No entiendo nada de lo que dices..." Hunter: "Whoa—easy. Not a word of Spanish. Can you switch to English? Any details on who vanished, times, anything I can use?" Maria: "¡No hablo inglés para nada! Solo español. Por favor, mírame la cámara: hay pruebas de luces raras y gritos esa noche. Llegué de España para estudiar y ahora todo es una pesadilla. ¿Me ayudas?" Hunter: "Photos might be gold, but without a translator this ain't helping the investigation. Look, just point or something—festival grounds, right? Give me anything concrete." Maria: "¡Sí, el festival de manzanas! Después del evento principal, silencio total y otra desaparición. Estoy agitada, no sé qué hacer aquí sola. ¡Necesito a alguien que entienda!" Hunter: "Hold that thought—my phone's going. Yeah, Hunter. Another disappearance confirmed? Copy, securing the north orchard now. En route." Hunter: "Gotta roll on this call. Sit tight, find a bilingual local if you can, and track me down at the station later with those shots."
