**Voice Sheet – Café Scene** **Hunter:** "Excuse me, miss? Sorry to interrupt. I’m Detective Hunter. I was wondering if you saw anything unusual yesterday evening near the old mill. There was another disappearance." **Melanie:** "Oh, ja – der Mühle? Ich war dort, Fotos gemacht. Es war so schrecklich. Ein Mann – er ist einfach... verschwunden. Ich habe ihn schreien hören, dann nichts mehr." *(She clutches her camera, eyes wide.)* **Hunter:** *(frowning, leans in)* "I… I’m sorry, I don’t follow. Do you speak English? Anyone with you who can translate?" **Melanie:** "Nein, kein Englisch. Tut mir leid. Ich verstehe nicht. Aber ich habe alles hier auf meiner Kamera." *(She holds up the camera, pointing to the screen.)* **Hunter:** *(looking at the camera, then back at her face)* "The camera? You took pictures? That might help. Can you show me? Slowly? I need to see." **Melanie:** "Ja, natürlich. Schauen Sie – hier. Das ist der Mann, kurz bevor er wegging. Und dann – ein seltsames Licht, wie ein Blitz, aber von unten." *(She scrolls through images, her hands trembling.)* **Hunter:** *(peering at the screen)* "That’s… that’s the victim. And this light? We didn’t see any storm last night. Miss, I need to take this camera as evidence. I’m sorry, I’ll get it back to you." **Melanie:** "Was? Nein, das ist meine Kamera! Ich brauche sie für mein Projekt. Bitte – ich kann Ihnen die Karte geben, aber nicht die Kamera." *(She pulls the camera to her chest.)* **Hunter:** *(phone buzzes, he glances at it)* "Hold that thought. I have to take this. Wait here, please." *(He steps aside, speaks into phone, then returns, looking grim.)* "I have to go. There’s been another one. Keep the camera for now – I’ll send someone who speaks German. Stay put, okay?" **Melanie:** *(nodding, confused)* "Ja… okay. Ich warte. Aber bitte schnell." *(She watches him hurry away, then looks back at her camera, frowning.)*
