# Voice Sheet: The Café Interview **Setting: A small café on Main Street, Alborn, MN. Late morning.** --- Hunter: "Excuse me, miss? Mind if I sit down? I'm Detective Hunter with the county sheriff's office." Marie: "Pardon? Je... je ne comprends pas." *(Sorry? I... I don't understand.)* Hunter: "I'm a detective. De-tec-tive. I need to ask you some questions about what happened at the apple festival grounds last night." Marie: "Oh, détective... oui, oui. La nuit dernière... c'était horrible. J'étais là avec mon appareil photo, je prenais des photos du coucher de soleil, et puis..." *(Oh, detective... yes, yes. Last night... it was horrible. I was there with my camera, taking photos of the sunset, and then...)* Hunter: "I'm sorry, I don't— do you speak English? Eng-lish?" Marie: "Non, non, je suis désolée. Français seulement. J'ai vu quelque chose dans les arbres. Une silhouette. Et puis j'ai entendu un cri terrible." *(No, no, I'm sorry. French only. I saw something in the trees. A figure. And then I heard a terrible scream.)* Hunter: "Okay, you're clearly upset. I can see that. Can you show me? On your camera maybe?" Marie: "Mon appareil? Oui, regardez... regardez ici. Cette photo. Vous voyez? Il y a quelqu'un là, dans l'ombre. Je ne l'ai remarqué qu'après." *(My camera? Yes, look... look here. This photo. You see? There's someone there, in the shadow. I only noticed it afterward.)* Hunter: "Wait— is that a person? Right there behind the barn? Can I see that closer?" Marie: "Oui, c'est ça qui me fait peur. Qui est-ce? Et cette femme qui a disparu... est-ce que c'est lié?" *(Yes, that's what scares me. Who is it? And this woman who disappeared... is it connected?)* Hunter: "I wish I knew what you were saying. This photo though... this could be important. Can I take this? Take... camera?" Marie: "Prendre mon appareil? Non, non, mais je peux vous envoyer la photo. Email? Vous avez email?" *(Take my camera? No, no, but I can send you the photo. Email? Do you have email?)* Hunter: "Email? Yes! Here, let me write down my— hold on." *Hunter's phone buzzes insistently.* Hunter: "Hunter here. What? Another one? Where? I'm on my way." Marie: "Qu'est-ce qui se passe? Vous devez partir?" *(What's happening? You have to leave?)* Hunter: "I'm sorry, I have to go. Stay in town, okay? Stay. Here. In Alborn. I'll find someone who speaks French and come back. Merci— that's thank you, right?" Marie: "Oui... merci. Soyez prudent, détective." *(Yes... thank you. Be careful, detective.)* Hunter: "I don't know what you just said, but I'll be back. Don't go anywhere." --- *Hunter hurries out of the café, leaving Marie clutching her camera, her eyes fixed on the shadowy figure frozen in her photograph.*
