# Voice Sheet: The Café Encounter **Setting:** A small café on Main Street in Alborn, MN. Late morning. Marie sits alone at a corner table, scrolling through photos on her camera. --- Hunter: "Excuse me, miss? Mind if I sit down for a moment?" Marie: *looks up, startled* "Pardon? Je... je ne comprends pas." Hunter: "I'm Detective Hunter. I'm investigating some incidents in town. Were you near the old mill yesterday evening?" Marie: *eyes widening, clutching her camera* "Le moulin? Oh mon Dieu... Oui, j'étais là. J'ai vu quelque chose de terrible. Une ombre, une silhouette qui traînait quelque chose vers la forêt..." Hunter: *frowning, leaning forward* "I'm sorry, I don't... Do you speak English?" Marie: *shaking her head, voice trembling* "Non, non... Anglais, non. Je suis désolée. C'était effrayant. J'ai couru. J'ai eu tellement peur..." Hunter: "Okay, okay... Uh, you were scared? Afraid?" *mimes frightened expression* Marie: *nodding vigorously* "Oui! Oui, peur! Très peur!" *gestures toward her camera* "J'ai des photos, peut-être... mais je ne sais pas si..." Hunter: "Photos? You have photos?" *points at camera* Marie: "Oui, photos..." *starts scrolling through her camera, hands shaking* Hunter: *phone buzzes* "Damn it." *answers* "Hunter here. ...What? Another one? I'm on my way." *hangs up, stands* "I have to go. Stay in town, okay? Stay." *gestures downward* "Don't leave." Marie: *confused, worried* "Je ne comprends pas... Qu'est-ce qui se passe dans cette ville?" Hunter: *sighs, frustrated* "I'll find someone who speaks French. Just... stay safe." *hurries out* Marie: *whispers to herself, looking back at her camera* "Qu'est-ce que j'ai photographié...?" --- *End of scene.*
