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.

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
Melanie: "Ich schaue gerade auf meine Kamera. Es ist schrecklich, was hier geschieht. Das macht mich nervös." Hunter: "Excuse me, miss. I'm Detective Hunter. There've been disappearances around Alborn. Have you seen or heard anything unusual lately?" Melanie: "Ich spreche kein Englisch." Hunter: "I don't speak German." Melanie: "Ich verstehe kein Englisch." Hunter: "Okay. Have you seen anything tonight—footsteps, lights, or people acting oddly?" Melanie: "Heute Nacht gab es hinter dem Café ein Rascheln. Eine Person mit Kapuze hat sich dort herumgeschlichen." Hunter: "Describe them as best you can." Melanie: "Große, schlanke Gestalt, ungefähr 1,80 Meter; die Kapuze verdeckte das Gesicht." Hunter: "I have to take this call. I'll step outside for a moment."
