Born in France, she is fluent in French and does not yet know any English. 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. Hunter has no knowledge of French, not even basic phrases. </character> <location name="Alborn, MN"> Alborne is a small town in the Midwest with a population of 3,000. It is known for its annual apple festival. </location>
User/Human

Marie sat at a small outdoor table in Alborn’s only café, the crisp autumn air carrying hints of cinnamon and apples from the town’s annual festival. Her camera rested on the table as she scrolled through landscape photos, her fingers trembling slightly at the strange images that had appeared in yesterday’s shots. Hunter approached with his usual direct stride, his former Marine posture making him stand out among the locals. **Voice Sheet:** Hunter: "Ma'am, I'm Detective Hunter. I understand you were taking photographs near the old orchard trail yesterday. We’ve had a disappearance, and I need to know if you saw anything unusual." Marie: "Je suis désolée, je ne parle pas anglais... J’ai vu un homme disparaître ! Il était là, près des arbres, et tout à coup il n’était plus là. J’ai tout photographié mais j’ai tellement peur, je ne comprends rien à ce qui se passe ici !" Hunter: "I don’t speak any French. Not a word. Do you understand me at all? English? Did you see the missing man?" Marie: "Non, je ne connais que le français. C’était horrible, il y avait une ombre bizarre et puis plus rien. Je suis encore sous le choc, j’ai du mal à dormir depuis hier soir !" Hunter: "This is frustrating. Photos? You have photos of what happened? Can you show me what’s on your camera?" Marie: "Mon appareil photo ? Oui, il y a des images étranges... une forme noire qui bouge. Je ne sais pas ce que c’est, mais je veux rentrer en France. Cette ville me terrifie !" Hunter: "Alright, slow down. You look really shaken. I’ll find someone who speaks French and come right back. Just stay in town for now." Hunter’s phone rang sharply. He glanced at the screen, his expression hardening. Hunter: "Hunter here. Another one? I’m on my way." He gave Marie an apologetic look, then turned and left the café at a brisk pace.
