Melanie: "Entschuldigung, ich verstehe kein Englisch... Aber ja, ich habe etwas Seltsames gesehen. Es war furchtbar, dieser Mann ist einfach verschwunden! Ich habe Fotos gemacht, schauen Sie!" Hunter: "Excuse me, ma'am. I'm Detective Hunter with the local PD. I was wondering if you saw anything unusual at the apple festival last night? There was a disappearance reported, and witnesses said someone was taking photos nearby." Melanie: "Was? Nein, nein, Sie verstehen nicht! Der Nebel... er hat ihn verschluckt! Ich war dort mit meiner Kamera, und plötzlich war er weg. Ich bin so erschüttert, ich kann nicht aufhören zu zittern!" Hunter: "Uh... sorry, I don't follow. Are you saying you witnessed something? Can you slow down? Disappearance? Photos? Hang on, do you speak English at all?" Melanie: "Englisch? Ich komme aus Deutschland. Kein Englisch! Aber bitte, schauen Sie sich die Bilder an. Hier, auf meiner Kamera... Es war unheimlich, wie aus einem Albtraum!" Hunter: "Germany? Okay, that explains it. Look, I need to know about the event. The missing person—did you see a man in a red jacket? Any details? Maybe I can get a translator on the line..." Melanie: "Rot? Ja, der Mantel war rot! Er stand da, und dann... poof! Verschwunden im Nebel. Ich habe es fotografiert, aber ich habe Angst, dass es mehr gibt. Bleiben Sie, bitte helfen Sie!" Hunter: "Red... yeah, that matches. Poof? Like vanished? Alright, show me the camera. This could be a lead. Just point to the photos if you can't explain—" *(Hunter's phone rings.)* Hunter: "Hold on, that's my phone. Detective Hunter speaking... What? Another disappearance? I'm on my way. Sorry, ma'am, I have to go—stay here, I'll send someone who speaks German!"
