I'm Detective Hunter with the Alborn Police Department. Mind if I ask you a few questions?" **Marie:** *[looks up, startled]* "Oh! Euh... bonjour, monsieur." **Hunter:** "I'm investigating the disappearances in town. Were you at the apple festival yesterday evening?" **Marie:** *[nervously clutching camera]* "Je... je ne comprends pas. Vous parlez français?" **Hunter:** *[frowning]* "I'm sorry, what? Do you speak English?" **Marie:** *[agitated, speaking quickly]* "Non, non! Écoutez, j'ai vu quelque chose d'étrange hier soir! Près du verger, il y avait... il y avait une silhouette!" **Hunter:** *[confused]* "Okay, hold on. You're not understanding me, are you?" **Marie:** *[pointing at her camera desperately]* "Les photos! Regardez les photos! Ici, dans mon appareil!" **Hunter:** *[holding up hands]* "Easy, easy. I can see you're upset about something. Let me see if I can..." *[pulls out phone, attempts to use translation app]* **Marie:** *[breathing heavily]* "Quelqu'un a disparu! J'ai tout vu! Vous devez me croire!" **Hunter:** "This damn thing is taking forever to load... Look, just stay calm, okay?" **Marie:** "Comment puis-je rester calme? Cette personne... elle était là, et puis... pouf! Disparue!" **Hunter:** *[phone rings]* "Hang on." *[answers]* "Hunter here. What? Another one? When? Dammit. I'm on my way." *[looks at Marie apologetically]* "I have to go. There's been another incident." **Marie:** "Attendez! Vous ne comprenez pas! Je peux vous aider!" **Hunter:** *[standing, frustrated]* "I'm sorry. I'll... I'll find someone who speaks French and come back. Don't leave town, okay? Stay. Here." *[gestures emphatically]* **Marie:** *[deflating in her chair]* "Mais... mais non... Personne ne me comprend..." **Hunter:** *[already walking away, calling back]* "I'll be back!" **Marie:** *[quietly, to herself]* "Il faut que je trouve un moyen de communiquer... Ces photos sont la clé de tout."
