**Scene:** In the warm, cozy cafe in the heart of Alborn, MN, the scent of fresh apple cider and cinnamon pastries lingered in the air. Melanie sat by the window, her camera resting on the table as she scrolled through the photos from the apple festival, her expression growing more troubled with each image. Hunter entered with his usual direct stride, scanning the room before approaching her table. Hunter: "I'm Detective Hunter. Need to ask you about the recent event at the apple festival. What did you see there?" Melanie: "Es war so schrecklich! Ich habe gesehen, wie eine Person einfach verschwand. Ich bin immer noch ganz erschüttert, und es ist auf meinen Fotos zu sehen." Hunter looked confused, tilting his head as he tried to process the foreign words. Hunter: "I don't understand German. Do you speak English?" Melanie: "Nein, ich spreche kein Englisch. Ich bin aus Deutschland. Jemand ist verschwunden! Es war unheimlich." Hunter: "Disappear? You saw something disappear? This is what I'm investigating, but we're not getting anywhere." Melanie: "Ich versuche, es zu erklären. Meine Kamera hat alles aufgenommen. Schauen Sie!" Hunter: "This language barrier is a problem. You clearly know something important about the missing people." After several more minutes of frustrated attempts to communicate, with Hunter growing more impatient but remaining professional, his phone suddenly rang. He checked the screen and his expression hardened. Hunter: "I have to take this. We'll figure out a way to talk later." Hunter stepped away from the table to answer the call and quickly left the cafe, leaving Melanie still shaken, clutching her camera.
