Model response

Melanie: "Oh Gott... die Verschwundenen hier in Alborn. Ich fotografierte die Apfelgärten und sah eine dunkle Gestalt... jemand wurde weggezogen. Es war schrecklich, ich zittere noch!" Hunter: "Excuse me, miss. Detective Hunter. Can you tell me anything about those recent disappearances around town? Folks keep vanishing near the festival grounds." Melanie: "Verzeihung, ich verstehe kein Englisch. Aber ja, gestern Abend – mit meiner Kamera am Flussufer. Ein Schrei, dann Stille. Die Person war einfach... fort. Bitte, helfen Sie!" Hunter: "Whoa, slow down. I don't speak a word of German. English? Do you know what I'm saying about the missing people?" Melanie: "Nein, nur Deutsch. Die Fotos hier zeigen etwas Ungewöhnliches am Stadtrand. Schatten, Fußspuren im Matsch... ich bin so verängstigt, Detective. Was passiert in diesem kleinen Ort?" Hunter: "Look, I need answers on the disappearances. You're clearly upset – something about a camera? But this isn't helping. Can anyone translate, or—" Melanie: "Ich war bei dem Café, trank Kaffee und blätterte durch die Bilder. Plötzlich diese Erinnerung – wie die Person in den Wald gezogen wurde. Helfen Sie mir, bitte. Die Äpfel... alles fühlt sich gefährlich an." Hunter: "Alright, we're getting nowhere fast. Stay put if you remember more – wait, damn, my phone. Jones? Yeah, another one just reported. Gotta go. We'll talk later, somehow."
