Marie: *sitting at a small outdoor café table in Alborn's town square, fiddling with her camera lens, lost in thought* Hunter: Excuse me, miss. I'm Detective Hunter with the local police. Mind if I ask you a few questions? We're looking into that disappearance from the apple festival last night—the young woman who vanished near the cider tents. Did you see anything unusual? Maybe take any photos? Marie: *looks up startled, her hands trembling slightly on the camera, eyes wide and troubled* Oh... non, je... je ne peux pas... J'ai vu une ombre, près des arbres. Quelqu'un l'a emmenée, je crois. C'était si sombre, si effrayant... Aidez-moi, s'il vous plaît! Hunter: *blinks, clearly confused, leaning in slightly* Uh... I'm sorry, what? I didn't catch that. Do you speak English? Anything you can tell me about the festival? Witnesses? Marie: *shakes her head, voice rising with agitation, gesturing vaguely toward the camera* Anglais? Non, je... Mon Dieu, l'odeur de pommes, et puis ces cris... Elle a disparu comme ça! *snaps her fingers, tears welling up* Pourquoi personne n'a rien vu? Hunter: *rubs his temple, frustration flickering across his face, no idea what she's saying* Look, this is important. The town's on edge with these vanishings. If you saw something— *pulls out his notebook, tries to mime taking a photo* —like with your camera? Photos of the crowd? Marie: *nods hesitantly, pointing at the camera but pulling it close protectively* Photos? Oui, j'en ai pris... mais je ne veux pas les revoir. C'était un homme, grand, avec un chapeau... Il la suivait. *whispers, shaken* Et si c'est lui qui... Hunter: *his phone buzzes loudly in his pocket; he glances at it, sighing* Hold on—damn it. *answers* Hunter here. Yeah? Now? Alright, on my way. *to Marie* Sorry, miss, duty calls. If you can find someone to translate, come by the station. We need to talk. *stands, nods awkwardly, and hurries off toward his car*
