# Voice Sheet: Cafe Scene **Marie:** *[muttering to herself in French]* "Ces photos... quelque chose ne va pas du tout..." **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, monsieur?" **Hunter:** "I'm investigating the disappearances in town. Were you at the apple festival yesterday?" **Marie:** *[nervously, speaking rapidly in French]* "Je... je ne comprends pas. Vous parlez français? J'étais au festival, oui, et j'ai vu quelque chose de très étrange près des arbres..." **Hunter:** *[frowning]* "I... what? Do you speak English?" **Marie:** *[shaking her head, distressed]* "Non, non! Anglais, je ne parle pas! Mais regardez—" *[frantically showing him her camera]* "—les photos! Regardez!" **Hunter:** *[taking the camera, confused]* "Okay, slow down. I don't understand what you're saying." **Marie:** *[pointing at camera screen, voice shaking]* "Là! Cette ombre! Je l'ai vu... quelqu'un a disparu juste après. J'ai peur!" **Hunter:** *[squinting at the photos]* "These are from the festival... What are you trying to tell me?" **Marie:** *[desperately]* "Comment je peux expliquer? Il y avait un homme... et puis plus rien! Disparu!" **Hunter:** *[sighing]* "Look, I can see you're upset about something, but I need someone who can translate—" **Marie:** *[pleading]* "S'il vous plaît, vous devez me croire! C'est dangereux ici!" **Hunter:** *[phone ringing]* "Hold on." *[answering]* "Hunter here... Yeah? Another one? Where? ... I'll be right there." **Hunter:** *[to Marie]* "I have to go. Stay here—I'll find someone who speaks French and come back." **Marie:** *[confused]* "Quoi? Vous partez? Non, attendez!" **Hunter:** *[already walking away]* "Just... stay put. I'll be back." **Marie:** *[calling after him, defeated]* "Monsieur! Les photos..."
