**Voice Sheet – Scene at the Café** Marie: *(looking up from her camera, startled)* "Pardon, monsieur ? Je ne parle pas anglais. Vous cherchez quelqu'un ?" Hunter: "Ma'am, I'm Detective Hunter. I need to ask you about the man who disappeared near the park yesterday. Did you see anything unusual?" Marie: *(frowning, voice shaky)* "Je… je ne comprends pas. Il y a eu un incident ? J'ai pris des photos, mais… tout allait bien. Pourquoi me demandez-vous ça ?" Hunter: *(sighs, rubs his forehead)* "Look, I know you don't speak English, but this is important. A man vanished. You were there. Just tell me what you saw." Marie: *(eyes wide, gesturing with her camera)* "Un homme a disparu ? Mon Dieu… je l'ai vu, oui. Il était près du vieux chêne. Il regardait autour, nerveux. Puis plus rien. J'ai cru que c'était un touriste." Hunter: "Okay, okay… slow down. I don't understand a word, but you look upset. Can you write it down? Or point? Anything?" Marie: *(shakes head, hands trembling)* "Je suis désolée… je ne peux pas vous aider si je ne parle pas votre langue. Peut-être… mon téléphone ?" Hunter: *(pulls out his phone, but it rings)* "Hang on—I have to take this. Stay here, alright? I'll be right back." *(answers phone, walks away)* "Hunter here. What have you got?" Marie: *(calling after him, desperate)* "Attendez ! Je n'ai pas fini ! Il y avait un bruit… comme un moteur…" *(Hunter disappears around the corner)* "…et puis il a crié." *(sits back down, staring at her camera, visibly shaken)*
