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 perturbada. No quiero hablar de ello, pero anoche vi cosas extrañas en la plaza." Hunter: "I don't speak Spanish. Tell me in English what you saw." Maria: "Vi sombras cerca de la fuente y oí un grito ahogado; después la plaza cayó en silencio. Alguien dejó una cámara en la banca y se fue." Hunter: "A camera? What are you talking about? Was anyone with you?" Maria: "Mi cámara está conmigo ahora. Yo solo quería fotografiar el festival, pero todo se siente mal, como si algo malo estuviera por pasar." Hunter: "Any detail helps. Where exactly did you see the shadows moving?" Maria: "Cerca de la torre del reloj, entre las sombras; parecían seguir a alguien." Hunter: "I need to take this call." Hunter: "I have to go for now. I'll circle back when I can."
