# Voice Sheet: Café Interview **Setting:** A small café on Main Street, Alborn, MN. Isabella sits alone at a corner table, scrolling through photos on her camera with trembling hands. --- **Hunter:** "Excuse me, miss? I'm Detective Hunter with the county sheriff's office. Mind if I ask you a few questions?" **Isabella:** *looks up, startled* "Cosa? Mi scusi, non... non capisco." **Hunter:** "I'm sorry, do you speak English? I need to ask about last night—the disappearance near the apple orchard." **Isabella:** *clutches camera tightly, voice shaking* "L'ho visto... quella notte, ero là per fotografare il tramonto. Ho visto qualcosa di terribile, ma non so come spiegare..." **Hunter:** *frowns, shifts weight* "Ma'am, I... I don't understand what you're saying. Do you have someone who can translate?" **Isabella:** *frustrated, gestures at camera* "Guardi! Guardi le foto! C'era un'ombra... una figura vicino agli alberi. Poi ho sentito un urlo e sono scappata." **Hunter:** "The camera? You want to show me something on the camera?" **Isabella:** *nods vigorously* "Sì, sì! Le foto!" *scrolls through images, hands trembling* "Qui... vedete? Questa ombra... non era normale. Ho paura, signore. Ho molta paura." **Hunter:** *leans in, squinting at screen* "That shadow there... that could be something. I wish I knew what you were trying to tell me—" *Phone rings* **Hunter:** *answers* "Hunter here. ...Yeah. ...Now? Alright, I'm on my way." *hangs up, turns to Isabella* "I have to go. Please—" *mimes staying put* "—stay in town. I'll find someone who speaks... whatever that is. Italian?" **Isabella:** *nods slowly* "Italiano, sì. Per favore... tornate presto. Non mi sento sicura qui." **Hunter:** *tips head in acknowledgment* "I'll be back, ma'am. Don't go anywhere." --- *Hunter exits. Isabella watches him leave, then looks back at her camera, her face pale.*
