She enjoys landscape photography and is always seen with her camera. </character> <character name="Hunter"> Hunter is a 35-year old detective who is investigating a series of mysterious disappearances in the small town of Alborn, MN. He is a former marine and has a no-nonsense attitude.

It is known for its annual apple festival. </location>
User/Human

**Scene:** Melanie sat at a small outdoor table of the café on Main Street in Alborn, MN. The autumn sunlight filtered through the changing leaves as she scrolled through the photos on her camera, her brow furrowed. The last few images from her walk near the old orchard two days ago still troubled her. Heavy footsteps approached. Hunter, dressed in a dark jacket with his detective badge clipped to his belt, stopped beside her table. **Voice Sheet:** Melanie: "…Entschuldigung… ich spreche kein Englisch. Ich habe nichts gesehen, nur Bäume… aber… da war etwas im Wald. Ich habe Angst. Die Person ist einfach verschwunden." Hunter: "Miss? I’m Detective Hunter. I’m investigating the disappearances. Mind if I ask you a few questions about what happened at the apple festival last weekend?" Melanie: "…Es war schrecklich. Ich habe nur fotografiert… plötzlich war die Frau weg. Ich habe versucht zu helfen, aber… ich verstehe nicht, was hier passiert. Bitte… ich bin nur eine Austauschstudentin." Hunter: "…Uh. I don’t speak German. Do you understand any English at all? English? Do you have any information about the missing people?" Melanie: "…Ich glaube, jemand beobachtet mich jetzt auch. Die Fotos… schauen Sie sich die Fotos an. Etwas ist im Hintergrund. Ich kann nicht schlafen seitdem." Hunter: "Okay… this isn’t working. Look, here’s my card. If you remember anything—or if someone who speaks English shows up—call me. We really need to figure out what’s happening in this town." Melanie: "…Bitte gehen Sie nicht. Ich habe Angst allein hier." Hunter: "I wish I could understand you. Stay safe, alright?" *(Hunter’s phone suddenly rings. He checks the screen, his expression tightening.)* Hunter: "Damn it… I have to take this. Excuse me." *(He gives her one last frustrated but concerned look, then turns and walks quickly away, answering the call.)* Melanie watched him leave, clutching her camera tightly to her chest, the untranslated fear still heavy in her chest.
