# Voice Sheet: Café Interview **Setting: A small café on Main Street, Alborn, MN** --- Hunter: "Excuse me, miss? Mind if I sit down? I'm Detective Hunter, with the county sheriff's office." Isabella: *looks up from her camera, puzzled* "Mi scusi? Non capisco..." Hunter: "I'm investigating some incidents in town. Were you at the apple festival grounds yesterday evening?" Isabella: *her eyes widen with recognition at "apple festival," becomes visibly shaken* "Il festival! Sì, sì, ero lì! Ho visto qualcosa di terribile... una persona, è scomparsa nel nulla! Un momento c'era, e poi..." *gestures frantically* "...poof! Sparita!" Hunter: *frowning* "I'm sorry, I don't understand. Do you speak English?" Isabella: *shakes her head apologetically* "Inglese? No, no... solo italiano." *taps her camera urgently* "Ma ho le foto! Guardi, guardi qui!" Hunter: "Photos? You took photos?" Isabella: *nods vigorously* "Sì! Foto!" *scrolls through her camera, hands trembling* "Questa donna... l'ho fotografata, e poi è scomparsa. Ho paura, signore. Ho molta paura." Hunter: *squints at the camera screen* "That's... that's one of the missing persons. Ma'am, I need to see these pictures. Can you— is there someone who can translate?" Isabella: *looks at him helplessly* "Non so cosa vuole che faccia. Mi può aiutare?" Hunter: *sighs, pulls out his phone to take notes* "This is going to be a long day—" *His phone rings* Hunter: *answering* "Hunter here. ...What? Another one? I'm on my way." *stands abruptly, looks at Isabella* "Don't go anywhere, okay? Stay. Here." *points at the ground emphatically* Isabella: *confused but nods slowly* "Restare qui? ...Va bene. Starò qui." Hunter: *hurrying toward the door, muttering* "I need to find a translator..." --- **END SCENE**
