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: *muttering to herself in Spanish while staring at her camera screen* Ay, Dios mío, no puede ser... Hunter: Excuse me, miss. I'm Detective Hunter with the Alborn PD. Mind if I ask you a few questions? Were you at the apple festival last night? Did you see anything unusual near the orchards? Maria: *looking up, troubled and shaken, eyes wide* ¡Sí, señor! Vi... vi un hombre. Estaba discutiendo con alguien, luego... ¡desapareció! Lo arrastraron al bosque, lo juro. ¡Era de noche, pero mi cámara lo captó! Hunter: Uh... I'm sorry, I don't speak Spanish. Do you understand any English at all? Festival? Orchard? *gesturing confusedly* Maria: *frustrated, pointing at her camera, speaking faster* ¡Mire! Aquí, en la foto. Hombre alto, sombrero... ¡y sangre! Por favor, tiene que investigarlo. ¡Estoy asustada! Hunter: Okay, slow down. Photo? *leaning in to look at camera* Blood? That looks like... whoa. Can you describe the man? Alto? Sombrero? *mimicking hat on head* Maria: *nodding vigorously* ¡Sí, alto! Sombrero negro. Y el otro... enmascarado. ¡Corrían hacia los árboles! ¿Entiende? ¡Policía, ayúdenme! Hunter: Masked guy? Trees? Alright, this might be connected to the disappearances. *pulling out notebook, trying to sketch* Like this? *shows crude drawing* You sure? Maria: *gasping, shaking head* ¡No, más grande! Y el grito... ¡un grito horrible! Debe parar esto antes de que pase de nuevo. Hunter: *phone buzzing, he checks it* Scream? Damn. Hold that thought— *answers call* Hunter here. Yeah? Another one? Location? Got it, en route. *to Maria* Stay here, okay? I'll get a translator. Don't go anywhere! Maria: *calling after him desperately* ¡Espere! ¡Vuelva! ¡Por favor!
