Melanie: *(staring down at her camera, barely noticing him)* "..." Hunter: "Excuse me, miss? Mind if I have a moment? Detective Hunter, Alborn PD." *(holds up badge)* Melanie: *(startled, looking up)* "Oh—entschuldigen Sie. Ich... ich habe Sie nicht kommen sehen." Hunter: "...Right. I'll take that as a yes." *(pulls out a chair, sits)* "I wanted to ask you about last night. Down by the old mill. You were in the area, weren't you?" Melanie: *(hands tightening around the camera)* "Die Mühle... ja. Ich war dort, um Fotos zu machen. Der Sonnenuntergang war so schön, und dann..." *(her voice wavers)* "...dann habe ich etwas gesehen. Etwas Schreckliches." Hunter: *(frowning)* "I'm gonna be honest with you, ma'am. I have no idea what you just said. Do you speak any English at all?" Melanie: "Ich verstehe Sie nicht. Bitte—es ist wichtig! Da war ein Mann, und ein anderer, und dann war er einfach... weg." *(gestures with her hands, frantic)* "Verschwunden!" Hunter: "Okay, okay, slow down." *(holds up both palms)* "You're upset. I get that much. Were you hurt? Are you hurt?" *(points at her, then makes a vague gesture)* Melanie: *(shaking her head quickly)* "Nein, nein, mir geht es gut. Aber der Mann—" *(she lifts the camera, turning the screen toward him)* "—sehen Sie. Schauen Sie sich das an." Hunter: *(leaning in to look at the screen, his expression shifting)* "Now that... that I understand. That's the mill. And that—" *(taps the screen)* "—who is that?" Melanie: "Ich weiß es nicht. Ich weiß nicht, wer er ist. Aber ich habe Angst." *(quietly)* "Ich habe wirklich Angst." Hunter: "You don't have to tell me. I can see it on your face." *(softening just slightly)* "Listen. I'm going to get someone who can translate, all right? Don't go anywhere. Stay right—" *(Hunter's phone buzzes loudly. He glances at the screen, jaw tightening.)* Hunter: "...Hunter. Yeah. Where?" *(stands abruptly, chair scraping)* "Got it. Two minutes." Melanie: *(half-rising)* "Was ist los? Müssen Sie gehen?" Hunter: "I have to go. I'm sorry." *(pointing firmly at the table, then at her)* "You. Here. Stay. I'll be back." *(grabs a napkin, scribbles a number, slides it to her)* "Anything happens, you call that. Understand? ...Probably not. But try." Melanie: *(clutching the napkin, watching him)* "Bitte... kommen Sie wieder." Hunter: *(already walking, calling back over his shoulder)* "Don't show that picture to anybody else, you hear me?" Melanie: *(to herself, looking back down at the camera screen)* "...Was habe ich nur gesehen?"
