# Voice Sheet: Cafe Scene **Melanie:** *[muttering to herself while examining camera]* "Das Licht war so seltsam heute Morgen..." **Hunter:** "Excuse me, miss. I'm Detective Hunter. Mind if I ask you a few questions?" **Melanie:** *[looks up, startled]* "Oh! Ah... ja?" **Hunter:** "I'm investigating some unusual activity in town. Were you near the old mill yesterday evening?" **Melanie:** *[visibly troubled, speaking quickly]* "Die Mühle? Ja, ich war dort! Es war schrecklich... Ich habe etwas gesehen, aber ich verstehe nicht—" **Hunter:** *[confused]* "Whoa, slow down. I don't... Do you speak English?" **Melanie:** *[shaking her head, distressed]* "Nein, nein. Ich spreche nur Deutsch. Es tut mir leid, aber ich muss Ihnen erzählen—da war ein Mann, und dann... verschwunden!" **Hunter:** *[frustrated, holding up hands]* "Okay, okay. I'm not understanding you. Do you... understand... me?" **Melanie:** *[desperately gesturing to her camera]* "Hier! Meine Kamera! Ich habe Fotos gemacht!" *[fumbling with camera buttons]* "Sehen Sie!" **Hunter:** *[leaning in]* "Photos? You took pictures?" **Melanie:** *[showing him the camera screen]* "Ja, ja! Fotos! Aber schauen Sie... dieser Schatten... was ist das?" **Hunter:** "That's... hmm. Can I—" *[phone rings]* "Hold on." *[answers]* "Hunter here. What? When? I'll be right there." **Melanie:** *[anxious]* "Was ist los? Wohin gehen Sie?" **Hunter:** *[standing up, pointing at camera]* "Stay here. Don't delete those photos. I'll find someone who speaks... whatever you're speaking. German? I'll be back." **Melanie:** *[calling after him]* "Warten Sie! Ich kann helfen! Bitte!" **Hunter:** *[over shoulder while leaving]* "Just... stay put!" **Melanie:** *[quietly, to herself]* "Was soll ich jetzt tun..."
