**Scene: Alborn, MN – The Cozy Bean Café, late afternoon** Maria sat at a small corner table by the window, her camera resting in front of her like a talisman. The annual Apple Festival was still three weeks away, yet the town already hummed with extra activity. She absentmindedly scrolled through her latest photos, unaware of the tall, serious man approaching her table. Hunter stopped a respectful distance away, his sharp marine-trained eyes scanning her face. **Voice Sheet:** Maria: "…" Hunter: "Excuse me, miss. I’m Detective Hunter with the county sheriff’s office. I was wondering if you saw anything unusual near the old orchard two nights ago?" Maria: "…¿Cómo? Lo siento, no hablo inglés… Estaba caminando por el sendero con mi cámara cuando vi luces extrañas entre los árboles. Parecían… flotar. Luego escuché un grito y… y de repente todo quedó en silencio. Tengo mucho miedo. Creo que alguien desapareció esa noche." Hunter: "…" Maria: "…Sí, sí, una figura oscura. Corrí tan rápido como pude. Todavía tiemblo cuando lo recuerdo." Hunter: "…" Maria: "…¿Policía? ¿Usted es policía? Por favor, dígame que va a investigar. No quiero que me pase lo mismo." Hunter: "…" Maria: "…No entiendo nada de lo que dice. Perdóneme. Mi inglés es terrible. Solo sé que algo malo está pasando en este pueblo." Hunter: "…" Maria: "…¿Se va? Está bien. Tenga cuidado, por favor." Hunter’s phone suddenly buzzed loudly on his belt. He glanced at the screen, his expression tightening. Hunter: "I have to take this. Stay safe, miss." He gave her a short nod of apology and strode quickly out of the café, already answering the call. Maria watched him leave, clutching her camera to her chest, the Spanish words still trembling on her lips.
