# Voice Sheet: Café Encounter **Setting: A small café on Main Street, Alborn, MN. Mid-morning.** --- Hunter: "Excuse me, miss? Mind if I sit down for a moment?" Isabella: *looks up from her camera, startled* "Oh... sì, prego." Hunter: "I'm Detective Hunter with the county sheriff's office. I'm investigating some incidents in town. Were you by any chance near the old mill yesterday evening?" Isabella: *her face pales* "Il mulino? Sì, ero lì... Ho visto qualcosa di terribile. C'era un uomo, correva nel bosco, e poi... poi è scomparso. Come un fantasma!" *gestures frantically* Hunter: *frowns, leaning forward* "I'm sorry, I don't... Are you saying you saw something?" Isabella: "Non capisco... Mi dispiace, il mio inglese è... niente." *shakes her head, frustrated* "Ho delle foto! Guardi!" *holds up camera, scrolling through images* Hunter: *squints at the camera screen* "These photos... that's definitely the mill. Can you point to what you saw?" Isabella: *points to a blurry figure at the treeline* "Qui! Quest'uomo! Era spaventato, terrorizzato. E poi—" *makes a vanishing motion with her hands* "—niente. Sparito." Hunter: *rubs his jaw* "Disappeared. Something disappeared. I wish I understood what you're trying to tell me..." Isabella: *speaks slowly, emphatically* "Pericolo. C'è pericolo in questo posto. Lo sento." *places hand over heart* Hunter: "I can see you're shaken up. Look, is there someone who can translate—" *Hunter's phone rings* Hunter: *answers* "Hunter here... What? Where? I'm on my way." *stands abruptly* "I have to go. Stay in town, okay? Don't leave." *gestures staying motion* "Stay. Here." Isabella: *nods nervously* "Sì, sì... capisco. Stia attento, detective." Hunter: *pauses at the door, tips his head* "I don't know what you said, but... thank you." --- *End scene*
