**Scene:** In the cozy corner of Alborn's only café, the scent of spiced apple cider and fresh pastries filled the air. Melanie sat alone at a wooden table near the window, her camera resting in front of her as she reviewed the landscape shots from the previous night’s apple festival. The small Midwest town felt anything but peaceful to her now. Hunter approached with his usual purposeful stride, his ex-Marine posture straight and serious. He pulled out the chair across from her. Hunter: "Excuse me, ma’am. I’m Detective Hunter. I’m investigating last night’s disappearance at the festival. You were seen taking photographs near the orchard path. Did you notice anything unusual?" Melanie looked up, visibly shaken, her hands trembling slightly as she clutched her camera. Melanie: "Es war schrecklich! Ich habe eine dunkle Gestalt gesehen… die Person war plötzlich einfach weg. Ich habe alles mit der Kamera aufgenommen, aber ich bin immer noch völlig durcheinander und habe Angst." Hunter looked confused, his brow furrowed as the rapid German washed over him. Hunter: "I… don’t understand German. Do you speak English? English? I need to know if you saw the missing man." Melanie: "Nein, ich spreche kein Englisch. Nur Deutsch. Es war so unheimlich… die Schatten, die plötzliche Stille." Hunter: "Slow down. Camera? Photos? Maybe your pictures show something. Can I look?" Melanie: "Die Fotos… ja, vielleicht helfen sie. Schauen Sie sich diese Aufnahme hier an. Der Schatten bewegt sich fast wie eine Person." Hunter: "I can’t understand what you’re saying, but those photos might be important. I’ll need someone who speaks German." Melanie: "Ich hoffe, die Bilder können helfen. Ich wollte nur Landschaften fotografieren… nicht so etwas." Hunter’s phone suddenly rang. He glanced at the screen and stood up quickly. Hunter: "This is Hunter. Yeah, I’m on my way. Ten minutes." He looked back at Melanie with an apologetic expression. Hunter: "I have to go. But I’ll return with a translator. Your photos might be the key." Hunter gave a curt nod and left the café, the bell above the door jingling behind him. Melanie remained at the table, still shaken, gently turning her camera over in her hands.
