# Voice Sheet: Cafe Scene **Isabella:** *[muttering to herself in Italian while reviewing photos]* "Questo non può essere vero... cosa ho fotografato?" **Hunter:** "Excuse me, miss. I'm Detective Hunter. I'm investigating some incidents in town. Mind if I ask you a few questions?" **Isabella:** *[looks up startled, speaks rapidly in Italian]* "Oh! Io... io non parlo inglese molto bene. Lei è della polizia?" **Hunter:** *[frowns]* "I... what? Do you speak English?" **Isabella:** *[shaking her head, troubled]* "No, no inglese. Io sono italiana. Ieri sera... ho visto qualcosa di strano nel bosco. Qui, guarda!" *[frantically shows camera screen]* **Hunter:** *[leans in to look, speaking slowly]* "What... am... I... looking... at?" **Isabella:** *[pointing at the camera, voice trembling]* "Una persona! Là, tra gli alberi! E poi... sparita! Come... come un fantasma! Io ho paura!" **Hunter:** *[sighs heavily]* "Okay, slow down. I don't understand a word you're saying. Do you have a translator app or something?" **Isabella:** *[pulls out phone, fumbling with it]* "Traduttore... sì, sì! Un momento..." *[struggles with the app]* "Questa cosa non funziona!" **Hunter:** *[gestures at the camera]* "Can I see that? The camera?" *[mimes taking a picture]* **Isabella:** *[nods, hands it over carefully]* "Sì, la macchina fotografica. Guardi le foto di ieri sera. Le ultime tre." **Hunter:** *[scrolls through photos, eyes narrowing]* "This was taken where? When?" *[points at screen, then at his watch]* **Isabella:** *[speaks urgently]* "Ieri! Nel bosco vicino al festival delle mele! C'era una luce strana e poi ho sentito urlare!" **Hunter:** *[looks increasingly frustrated]* "Festival... apple festival? You were at the festival grounds?" **Isabella:** *[nods vigorously]* "Sì! Festival! Mele!" *[makes eating gesture]* "Ma dopo... nel bosco... pericolo!" **Hunter:** *[his phone rings]* "Hold on." *[answers]* "Hunter here... Yeah... Another one? When?... I'll be right there." *[hangs up, looks at Isabella]* **Hunter:** "I have to go. There's been another incident. Can I take your camera? As evidence?" **Isabella:** *[clutches camera protectively]* "No, no! La mia macchina fotografica! È tutto quello che ho!" **Hunter:** *[pulls out business card, hands it to her]* "Okay, fine. Call this number if... just call. Somehow." **Isabella:** *[takes card, nods]* "Capisco. Lei deve andare. Ma per favore... aiuti questa città. C'è qualcosa di molto sbagliato qui." **Hunter:** *[already walking away, calls back]* "Stay safe, miss. And maybe learn some English!" *[exits quickly]* **Isabella:** *[watches him leave, whispers to herself]* "Dio mio, cosa sto facendo qui?" --- **[End Scene]**
