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: “Mein Gott… habe ich wirklich gerade ein Mädchen in einer grünen Jacke verschwinden sehen? Es war ganz plötzlich…” Hunter: “Excuse me, miss—mind if I ask you a few questions about what happened here last Friday?” Melanie: “Der Nebel… überall. Ich habe Fotos gemacht… und dann war das Mädchen weg. Es war wie ein… Trick.” Hunter: “I’m Detective Hunter. I’ve been talking to people who were at the festival.” Melanie: “Das Fest… ich habe eine Menschenmenge gefilmt, alles lachte… bis zu jenem Moment. Keiner hat sie bemerkt.” Hunter: “Anything unusual? Anyone leave in a hurry?” Melanie: “Ein Schatten, zwischen den Apfelbäumen. Nicht normal. Ich habe auch gefroren—konnte nichts sagen.” Hunter: “Can you describe the shadow? ” Melanie: “Es sah aus wie ein Mantel… sehr groß. Ich dachte erst an eine Statue, aber Statuen bewegen sich nicht.” Hunter: “All right, thanks for trying—” *Hunter’s phone rings. He steps away, glancing apologetically.* Hunter: “I’ve got to take this. Stay here if you’re willing, okay?”
