# Voice Sheet: Cafe Scene **Hunter:** "Excuse me, miss. I'm Detective Hunter with the local police. Mind if I sit down for a moment?" **Isabella:** "Oh, sì, prego." *[gestures to the seat]* **Hunter:** "I'm investigating some unusual activity in town. I noticed you've been taking a lot of photographs around Alborn. Have you seen anything strange in the past few days? Anyone acting suspicious?" **Isabella:** *[face goes pale, hands trembling slightly on camera]* "Io... io ho visto qualcosa. Due notti fa, vicino al vecchio mulino. Era terrificante." **Hunter:** *[blinks, confused]* "I... sorry, what? Do you speak English?" **Isabella:** *[shaking head, distressed]* "Non parlo inglese. È successo qualcosa di terribile! C'erano delle ombre, e poi... poi quella persona è semplicemente scomparsa!" **Hunter:** *[frustrated, speaking slowly and loudly]* "English? Do. You. Speak. English?" **Isabella:** *[frantically scrolling through her camera]* "Aspetti! Ho delle foto! Guardi!" *[shows him the camera screen]* **Hunter:** *[leans in to look at photos]* "Wait, what am I looking at here? When did you take these?" **Isabella:** "Due notti fa! Lunedì sera, verso le undici. Ero vicino al fiume." **Hunter:** *[pulls out notepad, pointing at it]* "Can you write down... look, I need to understand what you're trying to tell me." **Isabella:** *[takes notepad, writes in Italian]* "Non so come spiegare in inglese..." **Hunter:** *[sighs heavily]* "Great. Just great. Look, I can see you're upset about something, but I can't help you if I don't understand—" **Isabella:** *[voice rising, emotional]* "Qualcuno è in pericolo! Perché non mi capisce? Ho visto qualcosa quella notte!" **Hunter:** *[holds up hands calmingly]* "Okay, okay. Just... calm down. Let me think for a second." *[Hunter's phone rings]* **Hunter:** *[checks phone]* "I have to take this." *[answers]* "Hunter here. Yeah. What? When? I'll be right there." **Hunter:** *[standing up, speaking to Isabella]* "Listen, I need to go. But don't leave town, alright? I'll find someone who can translate and I'll come back to talk to you properly. Stay... stay here. At this cafe. Understand? This. Cafe." **Isabella:** *[confused, worried]* "Dove va? Ho bisogno di aiuto! Devo dirle quello che ho visto!" **Hunter:** *[already backing away]* "I'll be back. Just... wait here." *[hurries out of the cafe]* **Isabella:** *[calling after him]* "Aspetti! Per favore!" --- *End of scene*
