She enjoys landscape photography and is always seen with her camera. </character> <character name="Hunter"> Hunter is a 35-year old detective who is investigating a series of mysterious disappearances in the small town of Alborn, MN. He is a former marine and has a no-nonsense attitude.

**Scene:** The small café in Alborn, MN was quiet that afternoon, sunlight filtering through the windows onto wooden tables. Melanie sat near the corner, her camera resting on the table as she scrolled through the latest landscape photos she’d taken near the orchard. Her expression was focused, a slight furrow in her brow. Hunter entered, scanning the room with his usual sharp, no-nonsense gaze. Spotting the young woman with the camera—who matched the description of the German exchange student someone had mentioned—he approached her table. **Voice Sheet:** Melanie: "..." Hunter: "Excuse me. I’m Detective Hunter with the local sheriff’s department. I was told you might have been near the old mill last night. Did you see or hear anything unusual around dusk? Anything at all could help with the recent disappearances." Melanie: "Es tut mir leid... Ich habe nichts gesehen. Aber... da war dieses seltsame Licht im Wald, und dann diese Schreie. Es hat mich sehr erschreckt. Ich bin immer noch ganz zittrig. Können Sie mir sagen, was hier passiert? Ich verstehe das alles nicht." Hunter: "..." Melanie: "Bitte... Ich möchte nur wissen, ob ich in Gefahr bin. Die ganze Stadt fühlt sich plötzlich so bedrohlich an." Hunter: "I’m sorry, I don’t speak German. Do you understand any English? *slowly* English? Anyone here who can translate?" Melanie: "Ich spreche kein Englisch... Nur ein bisschen. Aber ich habe Angst. Etwas stimmt hier nicht." Hunter: "Right. This is... not helpful. Look, if you remember anything later, or if someone can translate for you, come find me at the station. We’ll figure this out." *(Hunter’s phone suddenly rings. He checks the screen, his expression tightening.)* Hunter: "I have to take this. Excuse me." *(He gives Melanie a short nod and walks quickly out of the café, answering the call.)* Melanie remains seated, looking shaken, her fingers tightening around her camera.
