**Scene:** The small café in Alborn, MN was quiet on this crisp autumn afternoon. Melanie sat at a corner table near the window, her camera resting on the wooden surface as she scrolled through the day’s landscape photos. The golden light filtering through the apple orchards outside had been perfect — until the strange event she’d witnessed earlier that morning. The bell above the door chimed. Hunter entered, his sharp eyes scanning the room with the practiced caution of a former marine. Spotting the young woman with the camera, he approached her table. **Voice Sheet:** Melanie: "..." Hunter: "Excuse me, ma’am. I’m Detective Hunter with the Alborn Sheriff’s Department. I understand you were near the old mill this morning. Mind if I ask you a few questions about what you might’ve seen?" Melanie: "Es tut mir leid… ich habe etwas Schreckliches gesehen. Ein Mann… er ist einfach verschwunden! Es war, als hätte ihn der Boden verschluckt. Ich bin immer noch ganz zittrig. Können Sie mir helfen? Ich verstehe nicht, was hier passiert." Hunter: "..." Melanie: "Bitte… ich spreche kein Englisch. Nur Deutsch. Haben Sie jemanden, der übersetzen kann? Es war so beängstigend. Ich wollte nur Fotos vom Herbstlaub machen und dann… dann war da dieser Schrei…" Hunter: "Right. I… don’t speak German. Not a word. But you look pretty shaken up. Something clearly happened out there. If you can just slow down and—" Melanie: "Der Schrei kam aus dem Nichts. Und dann war da dieses seltsame Licht… wie ein Nebel, der ihn eingehüllt hat. Ich habe versucht, Fotos zu machen, aber meine Hände haben so sehr gezittert. Schauen Sie… hier auf der Kamera. Sehen Sie das?" Hunter: "I’m sorry, I’m not following any of that. But I can tell you’re upset. Whatever you saw, it’s important. We’ve had three other people disappear in the last two weeks. If there’s anything at all you can—" Melanie: "Ich habe Angst, dass es wieder passiert. Dieser Ort… er fühlt sich falsch an. Können Sie mich beschützen? Oder wenigstens jemanden holen, der Deutsch spricht?" Hunter’s phone buzzed loudly on his belt. He glanced at the screen, his jaw tightening. Hunter: "Damn it. I’ve got to take this — it’s the station. Look, don’t go anywhere. I’ll be right back… or I’ll find someone who speaks German. Just stay put, okay?" Melanie: "Warten Sie! Gehen Sie nicht… ich habe noch mehr gesehen!" Hunter gave her an apologetic look, already moving toward the door as he answered the call. Melanie watched him leave, clutching her camera tightly, the untouched coffee growing cold beside her.
