# Scene: Alborn Café - Voice Sheet **Melanie:** *(looking at her camera's display, startled by Hunter's approach)* "Ja? Kann ich dir helfen?" **Hunter:** "Miss, I'm Detective Hunter. I'm investigating some incidents around town. Were you near the old Miller property yesterday evening?" **Melanie:** *(troubled, shaking her head)* "Ich... ich verstehe nicht. English? Nein, nein English." **Hunter:** *(pausing, frustrated)* "Do you... speak English at all?" **Melanie:** *(gripping her camera tightly, voice shaken)* "Nein. Nur Deutsch. Ich bin... I am from Germany. Study abroad." *(gestures nervously)* "Was ist los? What is... wrong?" **Hunter:** *(sighing, pulling out a small notebook)* "I need to know if you saw anything unusual. Yesterday. Evening. Around sunset." **Melanie:** *(eyes widening, speaking rapidly in German)* "Gestern? Ach Gott, ja... es war schrecklich. Ich habe Bilder gemacht—photographs—und dann... dann ist etwas Seltsames passiert." **Hunter:** "I have no idea what you just said, but you seem pretty upset about it." **Melanie:** *(frustrated, close to tears)* "I see... something. In the woods. Sehr dunkel. Very dark. I do not have the words..." *(holds up camera helplessly)* **Hunter:** *(leaning forward)* "Can you show me the photos on that camera?" **Melanie:** *(scrolling through images, pointing at several dark, blurred shots)* "Hier. Here. Etwas... something moved. Ich weiß nicht was." **Hunter:** *(examining the screen)* "These are too blurry. But you saw something move out there?" **Melanie:** *(nodding emphatically)* "Ja, ja. Something... or someone. Es war schrecklich angespannt. Tensión. The feeling was... nicht gut. Not good." **Hunter:** "Okay, I'm going to need you to—" *(Hunter's phone buzzes. He checks it, his expression darkening.)* **Hunter:** "Damn it." *(looking back at Melanie)* "I have to go. Stay in town. Don't go back to those woods." **Melanie:** "Wait! Du musst—you must understand, there was—" **Hunter:** *(already standing, phone to his ear)* "I'll send someone by who speaks German. Don't leave town." *(walking away)* "Yeah, I'm heading there now..." *(Melanie sits alone with her camera, troubled and uncertain.)*
