# Dialogue Voice Sheet: Cafe Encounter **Marie:** "Bonjour... Oui, bonjour." *(nervous smile, glancing at camera)* **Hunter:** "Hey there. I'm Detective Hunter. I'm investigating some disappearances around town. Were you near the old mill road yesterday evening?" **Marie:** "Pardon? Je... je ne comprends pas." *(looks confused, fidgeting with camera strap)* **Hunter:** "The mill road. Yesterday. Around six o'clock?" **Marie:** "Ah, non... non, non, non. Je suis désolée. Je ne parle pas anglais." *(shakes head, speaks more rapidly, distressed)* "C'était horrible... j'ai vu quelque chose de très étrange hier soir." **Hunter:** *(leans back, frustrated)* "Look, I don't know what you're saying, but I need to know if you saw anything." **Marie:** *(voice trembling)* "Oui, oui... j'ai vu une lumière bizarre, et puis... et puis la personne, elle a disparu. Juste comme ça! Envolée!" *(makes a disappearing gesture with her hand, clearly shaken)* **Hunter:** "Did you... take any photos? With that camera?" **Marie:** *(brightens slightly, understanding the word "camera"* "Camera? Oui! Oui, j'ai..." *(scrolls through device desperately)* "Regardez, regardez ici..." **Hunter:** *(takes out phone to look, but it immediately rings)* "Hold on a second." *(Hunter answers phone)* **Hunter:** "Yeah, this is Hunter... Uh-huh... Another one? Where?... I'm on my way." **Marie:** "Quoi? Que se passe-t-il?" **Hunter:** *(standing up, putting phone away)* "I gotta go. Don't leave town." *(walks away quickly)* **Marie:** *(calling after him, bewildered)* "Attendez! Attendez, s'il vous plaît!"
