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.
