# Voice Sheet: Cafe Scene **Marie:** *[mumbling to herself in French while reviewing photos]* "Mon Dieu, c'est impossible... qu'est-ce que j'ai photographié là?" **Hunter:** "Excuse me, miss. I'm Detective Hunter. Mind if I ask you a few questions?" **Marie:** *[looks up startled]* "Quoi? Je... je ne comprends pas..." **Hunter:** "I'm investigating the disappearances in town. Were you at the apple festival yesterday?" **Marie:** *[voice shaking]* "Le festival? Oui, oui! J'étais là! Mais il y avait... j'ai vu quelque chose de terrible! Dans les bois, près des pommiers!" **Hunter:** *[frowning]* "I... what? Do you speak English?" **Marie:** *[frantically gesturing at her camera]* "Regardez! Regardez les photos! Cet homme... il a disparu! Une seconde il était là, et puis... rien!" **Hunter:** "Slow down. I don't understand a word you're saying." **Marie:** *[frustrated, speaking rapidly]* "Comment puis-je expliquer? Vous devez comprendre! C'était hier soir, vers dix-neuf heures. J'ai tout photographié!" **Hunter:** *[pulls out notepad helplessly]* "Look, I need to understand what you're telling me. Is there someone who can translate?" **Marie:** *[calming slightly, tries hand gestures]* "Homme... disparu. Poof!" *[makes vanishing gesture]* **Hunter:** "Disappeared? Someone disappeared? You saw it?" **Marie:** "Oui! Oui! Disparu!" **Hunter:** *[leaning forward]* "Can you show me on your camera?" **Marie:** *[nodding vigorously, scrolling through photos]* "Voilà... ici, vous voyez? Et maintenant... regardez la suivante..." **Hunter:** *[studying the camera screen]* "That's... wait, that's the same spot but he's... gone?" **Marie:** *[whispering]* "Exactement. Il a disparu devant mes yeux. J'ai tellement peur..." **Hunter:** "These photos... this is evidence. I need—" *[Hunter's phone rings]* **Hunter:** *[answering]* "Hunter here. What? Another one? When? Damn it. I'm on my way." *[to Marie]* "I have to go. Don't leave town. I'll find a translator and come back." **Marie:** *[confused]* "Quoi? Où allez-vous? Attendez!" **Hunter:** *[already walking away]* "Stay here. I'll be back. Stay!" **Marie:** *[calling after him]* "Je ne comprends pas! Revenez!"
