Born in Germany, she is fluent in German and does not yet know any English. 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.

It is known for its annual apple festival. </location>
User/Human
Write the following scene: Melanie is sitting at a cafe, looking at her camera. Hunter approaches her and asks her about a recent event in the town. She responds troubled and shaken in German, and Hunter looks confused. They talk for a while, until Hunter gets a call and has to leave. Return the dialogue between Melanie and Hunter as a voice sheet: Melanie: "..." Hunter: "..."

Melanie: (looking troubled, clutching her camera, speaking rapidly in German with a shaky voice) Ich... ich habe gestern Abend etwas gesehen. Bei dem Apfel-Festival. Jemand... jemand ist einfach verschwunden. Es war dunkel, und ich habe Fotos gemacht, aber... es fühlt sich falsch an. Hilfe... Hunter: Excuse me, miss? I'm Detective Hunter with the Alborn PD. I saw you here earlier with that camera—mind if I ask if you've noticed anything unusual around town lately? The disappearances, maybe? Folks around the festival? Melanie: (eyes widening in distress, shaking her head) Nein, nein! Die Polizei? Ich weiß nicht... es war ein Mann, groß, mit Hut. Er hat mit jemandem gestritten, und dann—puff! Weg. Ich habe es fotografiert, aber ich habe Angst. Was, wenn sie mich finden? Hunter: Whoa, slow down. German, right? Look, I don't speak a lick of that. English? Parlez-vous... uh, anything? Can you describe it? Point? Anything about the guy who vanished? Melanie: (frustrated and still shaken, gesturing vaguely toward her camera) Englisch? Nein, ich bin aus Deutschland. Nur Deutsch. Der Mann... er war hier (points to the ground), dann... weg! Wie Magie, aber böse. Sehen Sie die Fotos? (fumbles with camera, showing blurry images) Hunter: Alright, pictures—good start. This one... looks like the orchard edge. Guy in a hat? That's helpful, even if I can't get the full story. Hang on, let me jot— (phone buzzes) Damn. Sorry, that's the station. I gotta take this. You stay safe, alright? We'll figure out a translator. Thanks for the pics. Melanie: (nodding anxiously as he leaves) Passen Sie auf sich auf, Herr Detektiv...
