Marie: "Pardon... je ne parle pas anglais. Je suis désolée." Hunter: "That's okay. I'm Detective Hunter, Alborn Police. I need to ask about last night—about the recent disappearance." Marie: "Je... j'ai vu quelque chose hier soir. Près du verger, à la lisière de la route. C'était tard." Hunter: "I don't understand French. Did you see anything unusual? Last night. Orchard. Disappearance." Marie: "Je ne comprends pas. Mais regardez, s'il vous plaît. Mon appareil. Les photos." Hunter: "Camera? Photos? Yes. Can I see?" Marie: "Oui. Tenez. Ici... là... vous voyez? Le camion." Hunter: "Truck. Okay. Dark blue? Is that right? What time was this?" Marie: "Hier soir, vers vingt et une heures. Juste avant la pluie. Je tremble encore." Hunter: "Nine-something... I can check the timestamp. Who was there? A man? A woman?" Marie: "Une fille... je crois. On l'a poussée dans le camion. Elle a crié, très vite, puis plus rien." Hunter: "Pushed? Someone pushed her into the truck? Did you see a face?" Marie: "Non. Casquette. Veste sombre. Tout allait trop vite. Il y avait l'odeur de pommes... des pommes pourries." Hunter: "Muddy plates? License plate—numbers? Letters?" Marie: "La plaque... couverte de boue. Je n'ai presque rien vu. Peut-être un C? Ou un G? Je ne sais pas." Hunter: "Got it. Where exactly? Show me." Marie: "À côté du grand hangar rouge, près des bacs de pommes. Là où le sol est boueux et la clôture est cassée." Hunter: "Red shed by the bins. Broken fence. Okay. Can I keep these photos? Copy them?" Marie: "Je... je préfère garder la carte SD. Mais vous pouvez copier, oui. S'il vous plaît." Hunter: "I can copy. Thank you. What's your name?" Marie: "Marie. Je suis étudiante. Échange universitaire." Hunter: "Marie. I'm Hunter. You're safe. We'll look into this." Marie: "S'il vous plaît... trouvez-la. Je n'arrête pas d'y penser." Hunter: "We will. Where are you staying?" Marie: "Chez une famille d'accueil, la maison bleue près de la bibliothèque. Je ne connais pas l'adresse exacte." Hunter: "Blue house by the library. Okay. If you remember anything else, call the station. Do you have a phone?" Marie: "Un téléphone, oui, mais... tout est en français. Je peux passer au poste?" Hunter: "Yes. Come by the station anytime today." Marie: "D'accord. Je viendrai. Et... je suis désolée de ne pas avoir aidé hier. J'ai eu peur." Hunter: "You did help. These photos help. Thank you." Marie: "Je reste ici un moment. Si vous avez besoin de plus de détails, je peux montrer d'autres clichés." Hunter: "Good. Hold on—" Marie: "Quoi?" Hunter: "Sorry, I have to take this. It's a call. I need to go." Marie: "Oh. D'accord. Je comprends." Hunter: "I'll be back. Please stay close, Marie." Marie: "Oui. Je reste. Faites attention." Hunter: "You too. Keep the camera with you."
