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

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: "..."

Model response

AI
Hunter: "Excuse me, miss. Detective Hunter here. I'm investigating a series of disappearances in town. Did you see anything unusual at the apple festival last week?" Melanie: "Oh Gott! Es war so furchtbar. Ich habe einen Mann gesehen, der plötzlich wegging. Ich habe Fotos auf meiner Kamera, die das zeigen, aber jetzt habe ich solche Angst!" Hunter: "I didn't catch any of that. You're not speaking English. Can you repeat what you saw about the event?" Melanie: "Entschuldigung, ich spreche kein Englisch. Der Mann ist verschwunden! Sehen Sie das hier auf dem Display? Es ist beängstigend." Hunter: "This is pointless without an interpreter. Do you have any English at all, or can you show me something on that camera?" Melanie: "Ich hoffe, Sie finden den Mann. Ich bin hier auf einem Studienprogramm und jetzt alles ist unheimlich." Hunter: "Hello? Detective Hunter speaking. Yeah, on my way—another lead just came in."
