The morning mist still clung to the damp pavement of Alborn as Hunter approached the small bistro table. He adjusted his coat, his eyes fixed on the young woman staring intensely at her camera screen. She looked pale, her fingers trembling as she scrolled through her shots. He cleared his throat, pulling out his badge just enough for it to be visible. Hunter: "Excuse me. I’m Detective Hunter. I’m looking into the disappearance of the Peterson boy. People say you were down by the old orchard around dusk yesterday. Did you see anything unusual?" Marie: "Monsieur? Oh, mon Dieu... Je ne savais pas à qui parler. J'ai vu quelque chose... quelque chose d'horrible près des pommiers. Une ombre, une silhouette qui ne bougeait pas comme un homme." Hunter: "Whoa, slow down. I don't speak... whatever that is. Did you see the boy? Little kid, red hat? I need a 'yes' or 'no' here." Marie: "Je ne comprends pas ce que vous dites, mais regardez ça... j'ai essayé de prendre une photo, mais c'était trop sombre. Regardez ses yeux sur l'écran. Ce n'est pas normal. J'ai eu si peur que j'ai couru jusqu'ici sans m'arrêter." Hunter: "Look, I need you to focus. Is this about the festival grounds? Did someone hurt you? You look like you’ve seen a ghost, lady, but I need names or directions, not a French lesson." Marie: "C'était là-bas, derrière la vieille grange! Il y avait une trappe cachée sous les feuilles. J'ai entendu un cri, un petit cri étouffé. S'il vous plaît, vous devez aller voir avant qu'il ne soit trop tard!" Hunter: "Listen, I’m sure your vacation is great, but I’m working a missing person case. Just... stay here. Don't leave town." [Hunter’s radio crackles loudly, followed by a sharp ring from his cell phone. He checks the ID and sighs, his face hardening.] Hunter: "Duty calls. That’s dispatch. Look, keep your photos. I’ll find someone at the station who can translate this mess later this afternoon. Stay put." Marie: "Attendez! Ne partez pas! L'enfant... il est peut-être encore là-dessous! Monsieur!"
