Born in France, she is fluent in French and does not yet know any English. She enjoys landscape photography and is always seen with her camera. </character> <character name="Hunter"> Hunter is a 35-year old detective who is investigating a series of mysterious disappearances in the small town of Alborn, MN. He is a former marine and has a no-nonsense attitude.

Hunter: "Ma'am, Detective Hunter. I need to ask you about what happened near the orchard last night." Marie: "Pardon... je ne parle pas anglais." Hunter: "You were there, right? At Peterson Orchard? Did you see the girl who went missing?" Marie: "J'ai vu quelque chose, oui... une ombre entre les pommiers. Et puis un cri. Mon Dieu, ce cri..." Hunter: "I'm sorry, I don't understand. Did you see who it was?" Marie: "Non, non... pas le visage. Seulement une silhouette. Grande. Très vite. C'était horrible." Hunter: "A silhouette? One person? More than one?" Marie: "Je ne sais pas! J'étais tellement effrayée. Quelqu'un était derrière moi aussi, je crois. Des pas... puis plus rien." Hunter: "Behind you? Somebody was following you?" Marie: "Oui—enfin, je crois. Je tremble encore. Je regardais avec mon appareil, et puis tout a disparu." Hunter: "Your... camera? Did you take a picture?" Marie: "Peut-être. Je ne sais pas. Mes mains bougeaient trop. Tout était flou." Hunter: "Ma'am, I need a clear answer, and I am not getting one." Marie: "Je suis désolée. Je voudrais aider, mais je ne comprends pas." Hunter: "Right. Okay. Stay calm. Don't go anywhere, all right?" Marie: "Quoi? Monsieur, attendez—" Hunter: "Hunter speaking... Yeah. When? ...I'm on my way." Hunter: "I've got to go. Stay here. I'll be back." Marie: "Mais non, attendez! Je ne comprends toujours pas!"
