# Voice Sheet: Cafe Scene **Hunter:** "Excuse me, miss. I'm Detective Hunter with the local police. Mind if I sit down for a moment?" **Marie:** "Oh... oui, d'accord." **Hunter:** "I'm investigating some unusual incidents around town. Have you noticed anything strange lately? Maybe something that caught your eye while you were out taking pictures?" **Marie:** "Je... je ne comprends pas bien. Vous parlez français?" **Hunter:** "I'm sorry, what? Do you speak English?" **Marie:** "Non, non... je parle seulement français. Je suis désolée." **Hunter:** "Okay, uh... English? You speak... English?" **Marie:** "Anglais? Non. Français. Je viens de France, je suis étudiante ici." **Hunter:** "Right. This is going to be difficult. Look, I'm trying to ask about what happened near the old mill yesterday. Were you there? Mill? Camera?" **Marie:** "Le moulin? Oui, oui! J'étais là-bas hier avec mon appareil photo. C'était... c'était terrible! J'ai vu quelque chose, quelque chose d'horrible!" **Hunter:** "Whoa, slow down. I don't... I can't understand you. You were there? At the mill?" **Marie:** "Oui! Le moulin! Il y avait une femme, elle criait, et puis... puis plus rien. Elle a disparu dans les bois. J'ai essayé de la suivre mais j'avais trop peur!" **Hunter:** "You're clearly upset about something. Did something happen? Someone hurt you?" **Marie:** "Non, pas moi! La femme! Je ne sais pas qui elle était. Tout s'est passé si vite. J'ai pris des photos mais elles sont floues..." **Hunter:** "Photos? You have photos? Can I see your camera?" **Marie:** "Mon appareil? Oui, attendez... les photos sont ici. Regardez, vous voyez? C'est tout ce que j'ai pu capturer." **Hunter:** "These are blurry, but... is that someone running? When did you take these?" **Marie:** "Hier soir, vers sept heures. Il faisait presque nuit. J'aurais dû appeler quelqu'un, mais je ne connais pas le numéro d'urgence ici, et mon anglais est..." **Hunter:** "Yesterday evening. Okay, I'm getting that much. Look, I need you to come down to the station. We have a translator who can help us." **Marie:** "Station? Police? Oui, je veux aider! Cette pauvre femme... j'espère qu'elle va bien." **Hunter:** "I wish I could understand you better. This seems important." *[Hunter's phone rings]* **Hunter:** "Hold on. Detective Hunter... Yes... What? Another one? Where? ...I'll be right there." **Hunter:** "I'm sorry, I have to go. Emergency. But don't leave town, okay? I'll find someone who speaks French and we'll talk again. Soon." **Marie:** "Vous partez? Mais attendez! Je dois vous dire ce que j'ai vu! C'est important!" **Hunter:** "I'm sorry. Stay here. Stay. Here. I'll be back." **Marie:** "Je ne comprends pas... Revenez! S'il vous plaît!"
