Marie: *looking troubled at her camera, muttering to herself* Mon Dieu... qu'est-ce que j'ai vu... Hunter: Excuse me, miss. I'm Detective Hunter. I understand you're a visitor here in Alborn. Did you happen to see anything unusual at the apple festival last night? Around the time Ms. Jenkins went missing? Marie: *shaken, eyes wide, speaking rapidly in French* Oui! Oui, j'ai photographié quelque chose... un homme avec un manteau noir, il tirait quelqu'un vers les bois près du stand de pommes! C'était horrible, il faisait sombre... Hunter: *confused frown* Uh... I'm sorry, I don't speak French. Do you understand any English at all? Parlez anglais? Marie: *frantic, shaking her head, pointing at her camera* Non, non anglais! Regardez! *shows him a blurry photo on the camera screen* Là, l'homme! Danger! Hunter: *leaning in, puzzled, trying to interpret* Okay... a man? In a black coat? *mimes pulling someone* Like this? Towards the woods by the apple stand? Marie: *nodding vigorously, voice trembling* Exactement! Il a enlevé quelqu'un, je le jure! Aidez-moi, s'il vous plaît! Hunter: Alright, that's helpful. Stay here, I'll get an interpreter or— *phone rings* Hold on. *answers* Hunter here... Yeah? Now? Damn. *to Marie* Excuse me, I gotta run. Don't leave town, okay? We'll talk more! Marie: *calling after him anxiously* Attendez! Monsieur!
