Here is the dialogue between Melanie and Hunter: Melanie: "Entschuldigen Sie?" Hunter: "Excuse me, miss. Detective Hunter Vance. Do you mind if I ask you a few questions about something that happened recently? I'm looking into the disappearances. Have you seen anything unusual around town? Especially yesterday evening?" Melanie: "Oh, Gott... Es war... es war so still, nachdem die Lichter ausgingen. Und der Schatten... er war einfach fort." Hunter: "I'm sorry, I don't understand. Are you speaking German? Do you speak English?" Melanie: "Nein, ich... ich kann nicht. Es tut mir leid. Die... die Lichter. Dunkelheit. Und dann... nichts." Hunter: "Okay, okay. Hold on. Is there anyone here who can translate? Or... can you point to something? Anything you saw, something strange?" Melanie: "Ich mache Bilder, verstehen Sie? Landschaft. Aber gestern Abend... es passte nicht. Es war... ein Loch. Ein leeres Loch, wo vorher etwas war." Hunter: "A hole? Something missing? Did you photograph it? Do you have it on your camera?" Melanie: "Nein... ich... ich habe es nicht fotografiert. Es war zu schnell. Aber ich _sah_ es." Hunter: "Right. So you saw something disappear, but you didn't get a picture of it. And you can't describe it to me in a language I understand." Hunter: "Do you have an address I can reach you at? Or contact information?" Melanie: "Melanie." Hunter: "Thank you. I'm Detective Vance. I'll... see if I can find someone to help us talk." Hunter: (On phone) "Vance. ... I'm on my way." Hunter: "Look, I'm really sorry, something just came up. I have to go. I'll be in touch." Melanie: "Auf Wiedersehen." Hunter: "Yeah, see ya."
