Melanie: *(murmuring to herself, scrolling through photos)* "Das kann doch nicht sein... das war doch gerade noch hier..." Hunter: "Excuse me, miss? Mind if I sit down? Name's Hunter, I'm a detective. I'm looking into what happened by the old mill last night." Melanie: *(looking up, startled)* "Oh—entschuldigen Sie, ich... ich spreche kein Englisch. Tut mir leid." Hunter: "...Right. You don't speak English. Great. Of course." *(rubbing his temple)* "Look, I just need to ask you a few questions. Last night. The mill. Did you see anything?" Melanie: *(hands trembling, clutching the camera)* "Ich habe etwas gesehen... da unten am Fluss. Es war dunkel, aber ich hatte meine Kamera dabei. Da war... da war eine Gestalt, und dann... dann war sie einfach weg." Hunter: "Okay, okay, slow down. I got maybe one word of that. 'Kamera.' Camera. You have pictures?" Melanie: *(nodding quickly, turning the camera toward him)* "Ja, ja! Hier, sehen Sie. Das ist es. Sehen Sie diese Person? Und auf dem nächsten Bild ist niemand mehr da. Niemand!" Hunter: *(leaning in, squinting at the screen)* "Huh. That's... that's a person right there. And then—nothing. Where'd they go?" *(looks at her)* "You took these? Last night?" Melanie: *(eyes welling up)* "Ich habe solche Angst. Ich verstehe das alles nicht. Was geht hier vor sich in dieser Stadt?" Hunter: "Hey, easy. You're shaking. I don't know what you just said, but you look scared half to death." *(softening)* "I'm gonna need that camera. Or these photos, at least. Comprende? Camera. I take. Find someone who speaks German." Melanie: "Sie wollen die Kamera? Nein—die kann ich Ihnen nicht einfach so geben, die ist alles für mich..." Hunter: "No, no—I'm not taking it from you. We'll figure this out. Together. Okay?" *(Hunter's phone buzzes loudly. He answers.)* Hunter: "Hunter. ...What? When? ...No, don't touch anything, I'm on my way. Two minutes." *(hangs up, stands abruptly)* "Listen—I gotta go. Another one. Somebody else is missing." *(points at her, then at the cafe table)* "You. Stay. Right here. I'll be back. Don't go anywhere with that camera, you understand? Stay." Melanie: *(confused, calling after him)* "Wohin gehen Sie? Warten Sie! Was soll ich denn jetzt tun?" Hunter: *(already walking away, over his shoulder)* "I have no idea what you just said. Just—stay put!" Melanie: *(alone again, looking down at the photo, whispering)* "...Niemand. Da ist einfach niemand mehr."
