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: "Estoy muy inquieta. En Alborn han desaparecido varias personas y no entiendo qué está pasando." Hunter: "I don't speak Spanish. Can you tell me what happened in English?" Maria: "No hablo inglés." Hunter: "Then please tell me what you know, in any way you can." Maria: "Vi sombras cerca del café y oí una conversación en voz baja junto a la plaza. Después, el silencio cayó." Hunter: "Shadows near the cafe? Was anyone harmed? Any names or hints?" Maria: "No oí nombres. Solo gestos y un murmullo. Pero el miedo se siente en el aire." Hunter: "Okay. I might need a translator to understand you fully, but try to tell me anything that could help." Hunter: "I have to take this." Maria: "Por favor, vuelve pronto." Hunter: "I have to go."
