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>

Model response

Melanie: "Oh Gott... die Verschwundenen! Ja, ich habe etwas Furchtbares gesehen. Es war gestern Abend am Waldrand, eine schattenhafte Gestalt hat jemanden einfach... mitgenommen. Ich bin so erschrocken!" Hunter: "Excuse me, miss. Detective Hunter, Alborn PD. I'm looking into these recent disappearances. Did you see anything unusual around town, maybe near the old trails or the lake?" Melanie: "Verschwinden? Ja genau! Meine Kamera hat es fast erwischt. Schauen Sie hier, dieses Landschaftsfoto... der Weg war leer, dann der dunkle Mantel. Ich verstehe gar nichts mehr, warum passiert das hier?" Hunter: "Whoa, slow down. I don't speak a word of German. Camera? Show me the pictures. Is that the park by the orchards? Looks like someone vanished right there." Melanie: "Genau der Park! Ich fotografiere Landschaften, ich bin nur Studentin hier... aber plötzlich war die Person weg. Es hat mich so erschüttert, ich kann kaum schlafen!" Hunter: "Park near the festival grounds? That tracks with two of the missing. Damn language barrier. Stay put, I need a translator fast—" Melanie: "Bitte helfen Sie! Die Leute hier sind so freundlich, und dann das... ich will nur meine Fotos machen und studieren!" Hunter: "Hold that thought. Hello? Yeah, Hunter here. Another one just reported? On my way right now. Sorry, miss—gotta run. Stay safe."
