Marie: "Oh mon Dieu... ces photos... je n'arrive pas à y croire." Hunter: "Excuse me, miss. Sorry to bother you, but you look like you were at the apple festival last night. Did you see anything unusual around 10 PM? Near the town square?" Marie: "Oui, oui ! J'étais là avec mon appareil photo. Il y avait cet homme... grand, avec un manteau noir. Il a suivi la jeune fille blonde, et puis... elle a disparu ! Comme les autres !" Hunter: "Uh... I'm sorry, do you speak any English? I don't understand. Festival? Missing girl?" Marie: "Je suis terrifiée ! J'ai une photo floue, regardez ! Il l'a emmenée vers les vergers. Police ! Appelez la police !" Hunter: "Whoa, slow down. Photo? Show me? Police... I'm the police. Detective Hunter. Can you point? Or write it down?" Marie: "Non, non, c'était sombre, mais son visage... des cicatrices ! Il faut arrêter ça ! Les disparitions, c'est lui ! S'il vous plaît, comprenez-moi !" Hunter: "Okay, scars? Man in black coat? Point to the picture... yeah, I see a shadow. This could be important. Can you come to the station? Translate app maybe?" Marie: "Station ? Oui, tout de suite ! Mais il est dangereux, il rôde encore !" Hunter: "(phone rings) Hunter here. Yeah? Another one? Where? Got it, on my way. (to Marie) Sorry, miss, emergency call. Stay here, I'll send someone with a translator. Don't delete that photo!" Marie: "Attendez ! Ne partez pas ! C'est urgent !"
