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.

Melanie: Es tut mir leid, ich bin sehr aufgewühlt. Letzte Nacht ist hier in Alborn etwas passiert, und ich habe gesehen, wie jemand verschwand. Hunter: I don't speak German. Tell me in English what happened, please. Melanie: Die Straßen waren leer, der Wind riss an den Bäumen, und eine Gestalt zeigte sich kurz hinter einem Auto. Dann war sie einfach weg. Hunter: A silhouette behind a car that disappeared? Was it a man or a woman? Any other details you can give me? Melanie: Es war eine Frau, dunkel gekleidet, mit Kapuze; sie wirkte gehetzt, und dann war sie verschwunden. Hunter: What street? Any landmarks or sounds I should be looking for? Melanie: Sie verschwand in die Gasse hinter dem Obststand, in der Nähe des Marktplatzes. Hunter: I appreciate it. I have to take this—urgent call from the precinct. I'll come back to talk when I can.
