Melanie: "Ach, diese Bilder... ich kann es nicht glauben." Hunter: "Excuse me, miss. Detective Hunter, Alborn PD. I saw you with that camera—were you taking photos at the Apple Festival last night? Near the main orchard?" Melanie: "Der Festival? Ja... ja, ich war dort. Mit meiner Kamera. Aber ich habe etwas gesehen... etwas Schreckliches!" Hunter: "You were there? What did you see? Slow down—do you speak English?" Melanie: "Nein, nein Englisch! Es war ein Streit! Zwei Männer, sie schrien, dann... puff! Der eine war weg. Verschwunden! Wie ein Geist!" Hunter: "Fight? Two men? One disappeared? Miss, I'm not following—" Melanie: "Groß, dunkle Haare, rotes Hemd! Er fiel fast in den Apfelbaum... dann nichts mehr. Polizei! Ich zeige Ihnen!" Hunter: "Tall guy, dark hair, red shirt? Wait, like this fellow?" *[shows phone photo of missing person]* Melanie: "Ja! Genau der Mann! Er hatte Angst, ich schwöre! Jemand hat ihn gezogen... in die Dunkelheit!" Hunter: "Okay, that's our missing guy—Robert Kline. Pulled into the dark? By who? Can you describe—" Melanie: "Ich weiß nicht! Ein Schatten, groß... bitte, helfen Sie! Es war nach Mitternacht, bei den Laternen!" Hunter: "Shadow? After midnight? Miss, this is huge. If you took photos—" *[Hunter's phone rings]* Hunter: "Hold that thought—Detective Hunter... Yeah? Another one? At the orchard edge? On my way. Ma'am, thank you—I gotta run. Station's on Main Street. Komm? Pictures—show someone!" Melanie: "Warten Sie! Bitte... seien Sie vorsichtig!"
