Melanie: "Es tut mir leid, ich spreche kein Englisch." Hunter: "I don't understand German. Please tell me what happened in English." Melanie: "Okay. Es geht um das Verschwinden von gestern Abend. Die Stadt ist nervös." Hunter: "A disappearance last night? What did you see or hear near the cafe?" Melanie: "Ich stand hier, fotografierte die Menge. Die Straßen waren ruhig, und plötzlich wurde es still. Jemand flüsterte meinen Namen." Hunter: "I still can’t understand that. We need a translator. Do you have anyone who can translate?" Melanie: "Wir brauchen dringend einen Übersetzer. Ich kann nur Deutsch." Hunter: "I have to take this call." Hunter: "I’ll arrange a translator and come back as soon as I can." Melanie: "Okay."
