**Voice Sheet: Cafe Encounter** Melanie: "Nein... nein, das kann nicht sein. Ich habe es mit eigenen Augen gesehen, aber es ergibt keinen Sinn." Hunter: "I'm sorry, ma'am, I don't understand. Do you speak English? I just need to ask you a few questions about what happened at the park yesterday." Melanie: "Der Mann... er war einfach weg. Ich habe mein Foto gemacht, und als ich wieder hinsah – nichts. Nur der Hut auf der Bank." Hunter: "Look, I don't know what you're saying, but you seem pretty shook up. Are you okay? Do you need a translator?" Melanie: "Ich brauche keinen Übersetzer. Ich brauche, dass mir jemand glaubt. Der Nebel kam so plötzlich... und dann war er verschwunden." Hunter: "Right. Fog. That's... not exactly helpful. I'm Detective Hunter. I'm looking into a series of disappearances. Did you see anyone unusual? A tall man, dark coat?" Melanie: "Er trug einen roten Schal. Ich habe ihn fotografiert, weil das Licht so schön war. Aber auf dem Bild – sehen Sie selbst – da ist nur der leere Rasen." Hunter: "A photo? Let me see. (Pause) Wait, that's weird. There's nobody in this shot, but you said you saw a man in a red scarf?" Melanie: "Ja! Genau das sage ich doch! Der Nebel hat ihn genommen. Ich weiß es. Ich habe es gesehen." Hunter: "Okay, okay. Take a deep breath. I'm going to write down your name. Do you have any ID? A passport?" Melanie: "Mein Name ist Melanie. Ich bin hier zum Studium. Aber das ist doch nicht wichtig, oder? Der Mann wird vermisst, nicht ich." Hunter: "Melanie. Got it. I'll have someone come by who speaks German. In the meantime, stay in town, okay? (Phone rings) Hold on, I need to take this." Melanie: "Bitte finden Sie ihn. Es war nicht natürlich. Das war... etwas anderes." Hunter: "(Into phone) Hunter here. Yeah? On my way. (To Melanie) I have to go. Stay put. I'll be in touch." Melanie: "Warten Sie! Was soll ich tun? Ich habe Angst." Hunter: "I'm sorry, I really can't understand you. Just... stay safe. (Exits quickly)"
