**Scene:** In the warm, cinnamon-scented Apple Orchard Café in Alborn, MN, Marie sat tucked in a window booth, her beloved camera resting on the checkered tablecloth. She scrolled through the previous weekend’s landscape shots from the apple festival, her fingers trembling slightly. The small Midwest town was quiet today, but the memory of what she had witnessed still haunted her. Heavy footsteps approached. Detective Hunter, broad-shouldered and all business, stopped at her table. He had noticed the young woman always clicking away with her camera and hoped she might be a lead in the string of baffling disappearances. The two attempted to speak. What followed was a comedy of confusion, worry, and one-sided urgency—until Hunter’s phone rang. **Voice Sheet:** Marie: "Oh mon Dieu... J'ai tout vu au festival. L'homme près des pommiers... il était là et puis il a simplement disparu ! Ma caméra a capturé quelque chose d'horrible, une ombre, un mouvement que je ne peux pas expliquer. Je suis encore toute secouée..." Hunter: "Ma'am, I'm Detective Hunter. I understand you were photographing the apple festival last weekend. Did you see anything connected to the disappearance of Mr. Thompson?" Marie: "Je ne parle pas anglais... Personne ici ne comprend ? C'était terrifiant ! Un instant il souriait, et l'instant d'après il n'était plus là. J'ai peur que ça recommence. Regardez les photos, s'il vous plaît, regardez !" Hunter: "I... don't speak French. Not a word. English? Do you speak English? The festival—did you see a man vanish? Any strange people hanging around?" Marie: "Il y avait une lumière bizarre juste avant qu'il disparaisse. Je pensais que c'était un effet du soleil sur l'objectif, mais maintenant je crois que c'est lié aux autres disparitions. Cette ville n'est pas aussi paisible qu'elle en a l'air !" Hunter: "Okay, this isn't working. I need a translator. But if you're saying you caught something on that camera, I need to see those pictures. Can you show me?" Marie: "Oui, regardez l'écran ! Là, dans le coin... vous voyez l'ombre ? Je n'ose plus sortir seule depuis ce jour. Qu'est-ce qui se passe ici ?" Hunter: "I have no idea what you're saying, but your face tells me it's bad. Whatever you saw, you're not alone in this. I'm going to figure it out." Marie: "Ne partez pas tout de suite ! J'ai d'autres photos qui pourraient aider... Je vous en prie, il faut que quelqu'un me croie." Hunter: "Hold on—it's the station calling. I have to take this. Don't go anywhere, okay? We'll... find a way to talk. Somehow."
