# Voice Sheet: Cafe Encounter **Marie:** "Bonjour... oui, bonjour." *(looks up from camera, eyes red-rimmed)* **Hunter:** "Hey there. Mind if I ask you a few questions? I'm Detective Hunter with the Alborn Police Department. There was an incident last night near the old mill—did you happen to see anything unusual?" **Marie:** "Je... je ne comprends pas. Parlez plus lentement, s'il vous plaît?" *(clutches camera nervously, shakes head)* **Hunter:** *(squints, speaking slower and louder as if volume helps)* "The. Mill. Last. Night. Did. You. See. Anything?" **Marie:** "Non, non... je suis désolée. Je ne parle pas anglais. Vous parlez français?" *(voice trembling)* "Il y avait quelque chose de terrible hier soir... près de la forêt. J'ai entendu des cris." **Hunter:** *(pulls out notepad, frustrated)* "Look, I don't know what you're saying, but I need you to work with me here. Were you outside yesterday evening or not?" **Marie:** *(stands up abruptly, distressed)* "Oui! Oui, j'étais dehors! J'ai vu quelque chose... quelque chose de très grave. Une lumière étrange et puis... plus rien. La fille, elle a simplement disparu!" *(grips the edge of the table)* **Hunter:** *(leans forward, trying to piece together her body language)* "Okay, okay... calm down. Did you see a person? A woman?" **Marie:** *(nods frantically, points toward her camera screen)* "Je l'ai photographiée! Regardez! Elle était là et..." *(trails off, turning camera toward him with shaking hands)* "...et maintenant elle n'existe plus." **Hunter:** *(examining the camera photos, understanding dawning)* "These photos... this is important. Can you—" *(Hunter's phone buzzes loudly. He checks it, his jaw tightens.)* **Hunter:** *(into phone)* "Yeah, I'm on my way." *(turns back to Marie)* "I have to go. Stay in town. Don't leave." **Marie:** *(confused, frightened)* "Quoi? Attendez! Vous devez m'écouter! C'est important!" **Hunter:** *(already heading toward the door, calling over his shoulder)* "I'll find someone who speaks French. Just... stay put." *(Hunter exits quickly. Marie sits back down slowly, staring at her camera, still trembling.)*
