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
Maria: "¿Anoche? Yo estaba tomando fotos... vi una luz, muy extraña, cerca de los árboles. Luego alguien gritó. Fue... fue horrible." Hunter: "Slow down. I only caught 'light' and 'trees.' Are you saying you saw someone?" Maria: "Sí... o creo que sí. Una silueta. No podía ver la cara. Tenía mucho miedo." Hunter: "I need plain English here, not guesses. Did this person talk to you? Touch you? Anything?" Maria: "No, no. Solo escuché pasos... y después silencio. Como si el aire se hubiera roto." Hunter: "Great. That doesn't help me much." Maria: "Lo siento. Estoy nerviosa. Desde entonces, no puedo dejar de pensar en eso." Hunter: "Wait—hold on. My phone's ringing. I have to take this. Don't go anywhere; I may need to come back and ask again." Maria: "¿Qué...? No entiendo... espere." Hunter: "Yeah, that's kind of the problem. I'll be back."
