# Voice Sheet: The Café Encounter **Setting: A small café on Main Street, Alborn, MN. Late morning.** --- Hunter: "Excuse me, miss? Mind if I sit down for a moment?" Marie: "Oh... oui, bien sûr." Hunter: "I'm Detective Hunter. I'm investigating some incidents in town. Were you by any chance near the old mill yesterday evening?" Marie: "Le moulin? Oui, j'y étais... pour prendre des photos du coucher de soleil. Mais... mon Dieu, ce que j'ai vu..." Hunter: "I'm sorry, I don't... Are you saying you were there?" Marie: "J'ai entendu des cris, monsieur. Des cris terribles près de la forêt. Et puis... plus rien. Le silence. C'était effrayant." Hunter: "Ma'am, I really need to understand what you're telling me. Do you speak any English?" Marie: "English? Non, non... je suis désolée. Je ne parle pas anglais. J'essaie de vous dire... quelqu'un avait peur. Quelqu'un criait à l'aide, j'en suis certaine." Hunter: "Okay, uh... cries? Crying? You heard crying?" Marie: "Oui! Oui, des cris! Et j'ai couru, j'ai couru vers ma voiture. Regardez..." Hunter: "Your camera. You took pictures? Can I see?" Marie: "Les photos... elles sont sombres, mais là, vous voyez? Cette silhouette près des arbres? Ce n'était pas un animal, monsieur." Hunter: "What the... Is that a person? When exactly—" *[Hunter's phone rings]* Hunter: "Detective Hunter. ...Yeah. ...Right now? ...Understood. I'm on my way." Marie: "Vous partez? Mais... qu'est-ce que je dois faire?" Hunter: "Look, I have to go, but don't leave town, okay? I'll find someone who speaks... who can translate. Stay here. Stay safe." Marie: "Je ne comprends pas, mais... d'accord. Soyez prudent, monsieur." Hunter: "I'll be back. Thank you, miss." --- *[Hunter exits hurriedly, leaving Marie clutching her camera, visibly shaken]*
