Melanie: *sits at the cafe table, fiddling with her camera, looking pensive* Hunter: Excuse me, miss. I'm Detective Hunter with the Alborn PD. Mind if I join you for a minute? I understand you're a visitor here—I'm looking into those recent disappearances around the apple festival. Did you happen to see anything unusual last weekend? Crowds, strangers lurking? *Hunter pulls out a chair and sits, notepad in hand. Melanie looks up startled, her face paling as she clutches her camera tighter.* Melanie: Ich... ich weiß nicht... Der Festival, ja. Aber ich habe etwas gesehen. Eine Frau, sie verschwand einfach... in der Menge. Es war dunkel, und jemand... jemand hat sie weggezogen. Ich bin so aufgewühlt, ich konnte niemanden warnen! *Hunter furrows his brow, leaning forward with a confused expression, clearly not understanding a word.* Hunter: Uh... sorry? I didn't catch that. English? Do you speak any English at all? This is important—about the festival. Disappearances. Anything you saw? *Melanie shakes her head vigorously, gesturing with her hands as if mimicking someone being pulled away, her voice trembling.* Melanie: Nein, kein Englisch. Nur Deutsch. Die Frau... sie schrie nicht, aber ihre Augen... voller Angst. Und der Mann, der sie nahm, er hatte eine Jacke mit dem Apfel-Logo. Bitte, Sie müssen mir glauben! Ich habe Fotos, aber sie sind unscharf... *Hunter rubs his chin, frustration evident, trying to piece it together from her tone and gestures. He nods slowly, pointing to her camera.* Hunter: Okay, slow down. Deutsch? Like... German? Look, if you saw something—a woman, a guy in an apple jacket? Pointing at the camera—photos? Can I see? This could help with the missing persons case. *Melanie hesitates, then flips open her camera, scrolling to blurry shots of the festival crowd, her hands shaking as she points emphatically.* Melanie: Ja, Fotos! Sehen Sie hier—die Menge, und dort... der Schatten. Ich dachte, es war nichts, aber jetzt... mit den Verschwindenen. Die Polizei muss das untersuchen! Ich fühle mich so hilflos hier. *Hunter squints at the screen, murmuring to himself, still lost on the words but noting her distress. He starts sketching a rough description in his notepad.* Hunter: Alright, I get it—you're shaken up. Festival, shadow, jacket... I'll have someone who speaks German come by later. What's your name? Where are you staying? We need to follow up on this. *Suddenly, Hunter's phone buzzes loudly. He checks it, his expression hardening.* Melanie: Melanie. Ich bin im Hostel am See. Bitte, rufen Sie an—es ist wichtig! Hunter: Melanie, got it. Hold on—damn, I gotta take this. Stay put, okay? Someone'll contact you. Thanks. *Hunter stands abruptly, answering the call as he walks away.* Hunter: Hunter here—yeah, on my way.
