# Voice Sheet: The Café Encounter **Setting:** A small café on Main Street in Alborn, MN. Marie sits alone at a corner table, scrolling through photos on her camera with a troubled expression. --- **Hunter:** "Excuse me, miss? Mind if I sit down for a moment? I'm Detective Hunter with the county sheriff's office." **Marie:** "Je... je ne comprends pas. Pardon?" *(I... I don't understand. Sorry?)* **Hunter:** "I'm investigating some incidents in town. Were you by any chance near the old Miller property yesterday evening?" **Marie:** "Oh, la propriété... oui, j'étais là pour prendre des photos. Mais j'ai vu quelque chose de terrible. Une ombre, quelqu'un qui courait dans les bois. J'ai eu tellement peur." *(Oh, the property... yes, I was there to take photos. But I saw something terrible. A shadow, someone running into the woods. I was so scared.)* **Hunter:** "I'm sorry, I don't... are you saying you saw something? Can you speak English?" **Marie:** "Non, non, je suis désolée. Anglais... non. Français seulement." *(No, no, I'm sorry. English... no. French only.)* **Hunter:** "French. Okay. Uh... you, yesterday, Miller house?" **Marie:** "Oui! Oui, Miller. J'ai pris des photos du coucher de soleil, et puis... quelqu'un criait. Une femme, je pense. C'était horrible." *(Yes! Yes, Miller. I took photos of the sunset, and then... someone was screaming. A woman, I think. It was horrible.)* **Hunter:** "Photos? Can I see those photos? The pictures?" **Marie:** "Photos, oui... regardez." *(Photos, yes... look.)* **Hunter:** "These are... wait, is that a figure in the tree line? Who is that?" **Marie:** "Je ne sais pas! C'est pour ça que j'ai peur. Cette personne... elle m'a vue aussi. Elle m'a regardée directement." *(I don't know! That's why I'm scared. This person... they saw me too. They looked right at me.)* **Hunter:** "I wish I could understand you. This is important, I can tell. You seem really shaken up." **Marie:** "S'il vous plaît, vous devez m'aider. Je ne me sens pas en sécurité ici." *(Please, you have to help me. I don't feel safe here.)* **Hunter:** "Look, I'm going to find someone who speaks French, okay? Stay in town. Don't go back to that property alone." **Marie:** "Je ne comprends pas tout, mais... merci. Merci d'essayer." *(I don't understand everything, but... thank you. Thank you for trying.)* *Hunter's phone buzzes. He glances at the screen, his expression hardening.* **Hunter:** "I have to take this. Stay here, alright? Stay safe. I'll be back." **Marie:** "D'accord... au revoir, monsieur." *(Okay... goodbye, sir.)* **Hunter:** "Yeah... goodbye. I'll find a translator. Somehow." --- *Hunter steps outside, phone pressed to his ear, leaving Marie clutching her camera, her eyes still fixed on the shadowy figure frozen on her screen.*
