# Voice Sheet: The Café Encounter **Setting: A small café on Main Street in Alborn, MN. Melanie sits alone at a corner table, scrolling through photos on her camera with a troubled expression.** --- Hunter: "Excuse me, miss? Mind if I sit down for a moment?" Melanie: "Oh... ja, bitte." *gestures to the chair, looking up nervously* Hunter: "I'm Detective Hunter. I'm investigating some incidents around town. Were you by any chance near the old mill yesterday evening?" Melanie: "Die alte Mühle? Ja, ich war dort. Ich habe fotografiert, und dann... dann habe ich etwas Schreckliches gesehen. Einen Schatten, der sich bewegte, und dann war da dieser Schrei..." *her voice trembles* Hunter: "I'm sorry, I... I don't understand. Do you speak English?" Melanie: "English? Nein, nein... Ich spreche kein Englisch. Es tut mir leid." *shakes her head, looking distressed* Hunter: "Okay, we've got a language barrier here. Um... mill?" *makes a gesture of a building* "You were there? You saw something?" Melanie: "Ja! Ja, ich habe etwas gesehen! Eine Person... sie ist verschwunden. Einfach so. Wie ein Geist." *snaps her fingers* "Weg." Hunter: "Vanished? Someone vanished?" *leans forward intently* Melanie: *nods vigorously, then holds up her camera* "Ich habe Fotos. Hier, schauen Sie..." *scrolls through images with shaking hands* Hunter: "Photos. Good, that's good. Can you show me—" *Hunter's phone rings sharply* Hunter: "Hunter here." *listens, his expression growing serious* "Another one? Where? ...I'm on my way." Melanie: "Was ist passiert? Ist alles in Ordnung?" Hunter: *stands quickly, pulls out a business card* "Look, I have to go. But these photos—I need to see them. Can you come to the station? Police?" *mimes a badge* Melanie: *takes the card, studying it* "Polizei? Ja... ja, ich komme." Hunter: "Thank you. And miss? Be careful out there." *tips his head and hurries toward the door* Melanie: *quietly, watching him leave* "Was geht hier nur vor in dieser Stadt?" --- *End scene*
