You are an expert novel author in the cozy mystery genre. Take the following details about characters/locations/... into account: <character name="Melanie"> Melanie is a 30-year old college student on a study abroad program. 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. Hunter has no knowledge of German, not even basic phrases. </character> <location name="Alborn, MN"> Alborne is a small town in the Midwest with a population of 3,000. 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: (troubled, in German) Ach, es war schrecklich... Ich habe etwas gesehen, gestern Abend beim Festival. Jemand ist einfach verschwunden, wie ein Geist! Hunter: Excuse me, miss? I'm Detective Hunter with the Alborn PD. Mind if I ask you a few questions? Were you at the apple festival last night? Did you see anything unusual around the time of the latest disappearance? Melanie: (shaken, voice trembling, in German) Die Polizei? Ich... ich weiß nicht, ob ich das erzählen soll. Es war dunkel, und dieser Mann... er hat sie in den Wald gezogen. Bitte, helfen Sie! Hunter: Uh, I'm sorry, I didn't catch that. Do you speak English? Festivalgoers mentioned a foreign student taking photos— is that you? Anything you can tell me about what happened? Melanie: (more upset, gesturing wildly, in German) Englisch? Nein, ich spreche nur Deutsch! Der Schatten... er war groß, bedrohlich. Wenn ich doch nur Fotos gemacht hätte... Hunter: German? Damn, alright, hold on—maybe I can get a translator on the phone. Look, just nod if you saw someone pulled into the woods or anything like that. This is important; people are vanishing. Melanie: (nodding frantically, in German) Ja, ja! Genau das! Holen Sie Hilfe, bevor es zu spät ist! Hunter: Okay, yes? That's a start. Describe the guy if you can—tall, short? Wait, my phone's buzzing... (answers call) Hunter here. What? Another one? I'm on my way. (to Melanie) Sorry, ma'am, duty calls. Stay safe—I'll send someone who speaks German to follow up.
