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

Maria: *looking troubled, speaking rapidly in Spanish with a shaky voice* ¿Qué pasó anoche en el festival? Vi a un hombre discutiendo con alguien cerca de los puestos de manzanas... luego simplemente... desapareció. Estaba tan asustada, no sé si debería decirlo, pero sentí que alguien me observaba. Hunter: Excuse me, miss. I'm Detective Hunter with the Alborn PD. I couldn't help but notice you're looking at photos—were you at the apple festival last night? Mind if I ask what you saw? Maria: *shaking her head, more agitated, gesturing vaguely toward her camera* No entiendo... Por favor, fue horrible. El hombre gritó algo sobre "deudas" y luego... nada. Corrí, pero mi cámara capturó... ¿puede ayudar? Mi inglés es cero. Hunter: Uh, English? Do you speak any English at all? *pausing, confused, trying to mimic her gestures* Festival? Man? Disappear? Can you show me the photos? Maria: *fumbling with her camera, showing a blurry image on the screen, voice trembling* Mira, aquí. Sombras, un forcejeo. No sé nombres, pero era alto, con sombrero. ¿Investiga las desapariciones? Tengo miedo, este pueblo parece tranquilo, pero... Hunter: Okay, that's... something. The shadows—looks like near the cider stand. *leaning in, nodding slowly* Disappearances, yes. Can you describe the man? Alto? Sombrero? *frustrated, rubbing his temple* Damn language barrier. Wait here a sec— *Hunter's phone rings loudly* Hunter: Hold on—Detective Hunter. Yeah, I'm at the cafe now. What? Another one? Be right there. *standing up abruptly* Sorry, miss, duty calls. If you can get someone to translate those photos for me later, come by the station. Stay safe.
