# Scene: Alborn Café - Dialogue Voice Sheet **SETTING:** *A small café in downtown Alborn. Melanie sits at a corner table, scrolling through photos on her camera. Hunter approaches, his detective badge visible on his belt.* --- Melanie: "..." Hunter: "Excuse me, miss? I'm Detective Hunter. I'm investigating some incidents that have occurred in town over the past few weeks. I noticed you were taking photographs near Maple Street yesterday afternoon. Did you happen to see anything unusual?" Melanie: "Ach, ja... ich meine, ja, es war schrecklich. Der Mann, er ist einfach... verschwunden. Ich habe es auf meiner Kamera nicht gesehen, aber die anderen Menschen, sie waren so erschrocken. Es war furchtbar." Hunter: *[Squinting slightly]* "I'm sorry—what? Do you speak English?" Melanie: *[Looking distressed, speaking faster in German]* "Nein, nein English. Nur Deutsch. Ich verstehe nicht... was haben Sie gefragt? Es war so erschrecklich, was ich gesehen habe!" Hunter: *[Clearly frustrated, rubbing his temple]* "English. Do you... speak... English?" *[Speaking slowly and deliberately, as if volume might help]* Melanie: *[Shaking her head, clutching her camera]* "Nein. Deutsch. Nur Deutsch. Bitte... ich bin sehr nervös." Hunter: *[Sighing, pulling out his phone to look for a translation app]* "Okay, okay. Just... give me a second here." Melanie: *[Quietly, in German]* "Der Mann war dort... und dann war er weg. Ich weiß nicht, was passiert ist." Hunter: *[Phone buzzes. He glances at it, then back at Melanie]* "Look, I wish I could understand you, but—" *[His phone rings. He holds up a finger.]* Hunter: "One second." *[Answers]* "Hunter here... Yeah, we got another lead on the Patterson case... I'm on my way." *[Hangs up, looks apologetic]* "I'm sorry, miss. I have to go. But we're going to need to finish this conversation—with a translator." Melanie: *[Nodding anxiously, still in German]* "Ja... ja, natürlich. Ich erzähle Ihnen alles, was ich weiß." Hunter: *[Heading toward the door, muttering to himself]* "This day just got a whole lot more complicated..." --- **END SCENE**
