# Voice Sheet: The Café Encounter **Setting: A small café on Main Street, Alborn, MN. Late morning.** --- Hunter: "Excuse me, miss? Mind if I sit down for a moment?" Maria: *looks up from her camera, startled* "¿Perdón? ¿Puedo ayudarle?" Hunter: "I'm Detective Hunter with the county sheriff's office. I'm investigating some incidents in town. Were you anywhere near the old mill last Tuesday evening?" Maria: *eyes widening, voice trembling* "¡El molino! Sí, sí, estuve allí. Vi algo terrible... había sombras, y escuché gritos. ¡Tenía mucho miedo! Corrí tan rápido como pude." Hunter: *frowning, leaning forward* "I'm sorry, I don't... Do you speak English?" Maria: *shaking her head, gesturing anxiously* "No inglés. Lo siento. Pero tiene que entenderme... lo que vi esa noche... no era normal. ¡Algo está muy mal en este pueblo!" Hunter: "Look, I can see you're upset about something. The mill? Is that what's bothering you?" Maria: *nodding vigorously, pointing at her camera* "¡Fotos! Tengo fotos. Mire, mire aquí..." *scrolls through images with shaking hands* "¿Ve? Las luces... las figuras..." Hunter: *squinting at the camera screen* "These photos... that's definitely the mill. And those lights—" Maria: "¡Exacto! ¡Las luces! Aparecieron de la nada. Y después... después escuché a alguien gritar y todo quedó en silencio." Hunter: *sighing, rubbing his temple* "I wish I knew what you were saying. This could be important." Maria: *frustrated, speaking slowly* "Peligro. ¿Entiende? Peh-lee-gro." Hunter: "I'm getting maybe one word in ten here..." *Hunter's phone rings* Hunter: *answering* "Hunter here. ...Yeah. ...Now? Alright, I'm on my way." *stands up, looks at Maria apologetically* "I have to go. But I'm going to find someone who speaks Spanish and come back. Don't go anywhere, okay? Just..." *mimes staying put* "...stay?" Maria: *nodding slowly* "¿Volver? ¿Va a volver?" Hunter: *placing a business card on the table* "My card. Call if... well, find someone to call for you." *tips his head and hurries out* Maria: *watching him leave, muttering to herself* "Este pueblo guarda secretos oscuros... y nadie me puede entender." --- **END SCENE**
