**Scene:** The late afternoon sun filtered through the windows of the small café on Main Street in Alborn, MN. Marie sat at a corner table, her dark hair falling across her face as she scrolled through the photos on her camera. Her fingers trembled slightly against the device. Hunter entered the café, his tall frame casting a long shadow. He scanned the room with the practiced eye of a former Marine, then spotted the young woman with the camera. He approached her table. **Voice Sheet:** Marie: "Qu'est-ce que vous voulez ? Je... je ne sais pas... l'homme a juste disparu... comme ça... J'ai peur. Je ne comprends rien à tout ça !" Hunter: "..." Marie: "S'il vous plaît, laissez-moi tranquille. Tout le monde ici agit comme si de rien n'était, mais j'ai vu quelque chose. J'ai vu son visage avant qu'il ne disparaisse ! Mon Dieu, pourquoi personne ne me croit ?" Hunter: "..." Marie: "Vous êtes de la police ? Vous devez m'aider. Personne ne parle français ici et je... je suis toute seule. J'ai seulement pris des photos du festival des pommes... et maintenant... maintenant il y a cet homme qui a disparu juste après que j'ai pris sa photo !" Hunter: "..." Marie: "Je suis désolée... je parle trop vite quand j'ai peur. Vous ne comprenez rien, n'est-ce pas ? Personne ne comprend..." *(Hunter's phone suddenly rings. He checks the screen, his expression shifting to one of urgency.)* Hunter: "I have to take this. Stay safe, miss." *(Hunter nods once at Marie, then turns and strides quickly out of the café, phone already to his ear.)*
