**Scene:** In the warm glow of the Cozy Apple Café in Alborn, Minnesota, the scent of cinnamon cider and fresh pastries filled the air. Maria sat tucked in a window booth, her beloved camera resting on the checkered tablecloth as she flicked through the day’s landscape shots from the apple festival. The small town outside seemed deceptively peaceful, yet an uneasy undercurrent had settled over the festival since the latest disappearance. Heavy footsteps approached. Hunter, the town’s no-nonsense detective, stopped at her table. His sharp eyes scanned her camera before he spoke. Maria: "¡Ay, no...! Vi lo que pasó en el festival. Un hombre... se llevó a alguien entre los árboles. Tenía una cara que nunca olvidaré. Estoy temblando desde entonces. ¿Qué hago? No conozco a nadie aquí." Hunter: "Ma’am, I’m Detective Hunter. I need to ask you about the disappearance at last weekend’s apple festival. Did you see anything unusual?" Maria: "¡Sí, sí! Todo estaba tan bonito con las manzanas y las fotos, pero entonces... la sombra. La persona simplemente desapareció. Tengo miedo de que vuelva. Mire, mire las fotos, tal vez se vea algo..." Hunter: "I don’t understand a word you’re saying. Spanish? Do you speak any English at all? English? I’m investigating missing people. Missing. People." Maria: "Desaparecidos... sí. Vi a uno de ellos. Estaba tomando fotos del paisaje y de repente... grité pero nadie me entendió. Todavía tengo las imágenes aquí. Por favor, ayúdeme a entender qué está pasando." Hunter: "Camera? You’re pointing at the camera. Did you photograph something? Damn it, this language barrier is going to get someone else killed. I need a translator. Are you willing to come down to the station?" Maria: "La estación... no entiendo. Solo sé que algo malo está ocurriendo en este pueblo tan pequeño. Las fotos... tal vez las fotos digan la verdad." Hunter: "Look, I can see you’re shaken. Whatever you witnessed clearly scared you. I wish I could understand you. Just... stay in town. Don’t go wandering alone." Maria: "No me deje sola... por favor. Siento que me observan también." At that moment Hunter’s phone buzzed loudly. He glanced at the screen, his jaw tightening. Hunter: "I have to take this. Another lead just came in. We’re not finished here. I’ll find someone who speaks Spanish and come back for you." Hunter gave her one last frustrated but concerned look, then turned and strode quickly out of the café, the bell above the door jingling behind him. Maria clutched her camera to her chest, the untouched cider growing cold on the table.
