# Voice Sheet: Café Scene **Marie:** *[muttering to herself while reviewing photos]* "Mon Dieu, qu'est-ce que c'était..." **Hunter:** "Excuse me, miss. I'm Detective Hunter with the local police. Mind if I ask you a few questions?" **Marie:** *[looking up, startled]* "Oh! Euh... bonjour?" **Hunter:** "I'm investigating the disappearance near the old mill yesterday. Were you in that area?" **Marie:** *[anxious, speaking rapidly]* "Je... je ne comprends pas. Vous parlez français?" **Hunter:** "I'm sorry, what? Do you speak English?" **Marie:** *[shaking her head, clutching her camera]* "Non, non... anglais, je ne parle pas anglais. Hier, j'ai vu quelque chose de terrible près du moulin!" **Hunter:** *[frowning]* "Ma'am, I need you to... slow down. English?" **Marie:** *[frustrated, pointing at her camera]* "Photos! Regardez! Le moulin... disparu... l'homme!" **Hunter:** "You're showing me your camera? Did you see something at the mill?" **Marie:** *[nodding vigorously]* "Oui, oui! Le moulin! J'ai vu... *[voice trembling]* ...quelqu'un dans l'ombre, et puis plus rien. Disparu!" **Hunter:** "Okay, I'm getting 'mill' here, but I need details. This is frustrating." **Marie:** *[desperate]* "Comment puis-je vous expliquer? Il faut que quelqu'un traduise!" **Hunter:** "A translator... right. That's what we need. Can you come down to the station?" **Marie:** *[uncertain]* "Station? Je... je ne sais pas ce que vous voulez dire." **Hunter:** *[gesturing]* "Station. Police station. Come with me?" **Marie:** *[hesitant]* "Police? Oui... d'accord. Mais mes photos... elles sont importantes!" **Hunter:** "Your photos, yes. We'll look at those. Just—" **Hunter's Phone:** *[rings]* **Hunter:** *[answering]* "Hunter here. Yeah? Another one? Where? Damn it. I'll be right there." **Hunter:** *[to Marie]* "Look, I have to go. Another incident. Stay here, okay? Stay. Here." **Marie:** *[confused]* "Vous partez? Mais... attendez! Et mes photos?" **Hunter:** *[already walking away, turning back]* "I'll send someone who speaks French. Don't leave town!" **Marie:** *[calling after him]* "Je ne comprends pas! Monsieur! Monsieur!" **Marie:** *[sitting back down, to herself]* "Qu'est-ce que je vais faire maintenant?"
