Melanie: *(scrolling through camera photos, murmuring to herself)* "Das kann doch nicht sein... das war doch gestern Abend noch da..." Hunter: "Excuse me, miss? Mind if I ask you a few questions?" Melanie: *(looking up, startled)* "Oh—hallo. Ähm... entschuldigen Sie, ich verstehe leider nicht so gut..." Hunter: "Detective Hunter, Alborn PD. I'm looking into some disappearances around town. You were out by the old mill yesterday evening, weren't you? Someone said they saw a young woman with a camera." Melanie: *(eyes widening, voice trembling)* "Die Mühle... ja, ja, ich war dort. Aber etwas war komisch. Ich habe etwas gesehen—oder gehört—ich weiß es nicht mehr genau..." Hunter: *(frowning)* "I'm sorry, I don't... is that German? Do you speak any English at all?" Melanie: "Englisch? Nein... nur ein bisschen, ganz wenig." *(holding fingers close together)* "Ich bin erst seit zwei Wochen hier. Aber bitte—Sie müssen sich das ansehen." *(turning camera toward him with shaking hands)* Hunter: *(leaning in, squinting at the screen)* "What is that? Is that... somebody standing in the trees? When did you take this?" Melanie: "Gestern. Gestern Abend, bei der Mühle. Ich wollte nur den Sonnenuntergang fotografieren, und dann—" *(she stops, hugging the camera to her chest)* "Es war jemand da. Und heute Morgen ist das Foto... anders. Verstehen Sie? Anders!" Hunter: "You're shaking. Hey—it's okay. I can't understand a word you're saying, but somethin's got you spooked, that much I can read." *(he pulls out a notepad)* "Mill. Photo. You. Got it. Look, is there someone who can translate—" Melanie: *(grabbing his sleeve, urgent)* "Bitte, hören Sie mir zu! Da war jemand, und jetzt sind Leute verschwunden, und ich glaube, ich habe es gesehen, ich habe es auf dem Foto—" Hunter: *(his phone rings; he holds up a finger)* "Hold that thought. Hunter." *(pause, his expression hardening)* "Where? ...When? ...Don't touch anything. I'm five minutes out." *(he stands abruptly)* Melanie: *(looking up at him, lost)* "Was ist los? Was ist passiert?" Hunter: "I gotta go. Listen—" *(he sets a business card on the table)* "Call me. Get a translator, get anybody. That photo—I want to see that photo. You understand? Phone." *(mimes a phone to his ear)* "Call." Melanie: *(clutching the card)* "Telefon... ja. Ja, okay." Hunter: "Good. Don't go back to that mill. Whatever you saw—stay put." *(already walking)* "Stay safe, kid." Melanie: *(to herself, watching him leave, voice small)* "...Was hast du gesehen, Melanie? Was hast du nur gesehen?"
