# Voice Sheet: The Café Interview **Setting: A small café on Main Street, Alborn, MN. Late morning.** --- Hunter: "Excuse me, miss? Mind if I sit down? I'm Detective Hunter with the county sheriff's office." Isabella: *looks up from camera, startled* "Scusi? Non capisco..." Hunter: "I'm investigating the disappearance of a local woman. Sarah Mills. Were you in town last Tuesday evening?" Isabella: *eyes widening with recognition at the name* "Sarah? Oh, Dio mio... L'ho vista! L'ho vista quella sera vicino al lago. Stava parlando con qualcuno nell'ombra. Era così strano, così inquietante..." *clutches camera nervously* Hunter: *frowning, leaning forward* "I'm sorry, I don't... Do you speak English?" Isabella: *shaking her head, gesturing frantically* "No, no English. Mi dispiace. Ma devo dirle—quella notte, ho scattato delle foto. Forse... forse c'è qualcosa..." *taps her camera* Hunter: "Photos? You took photos?" *points at camera* "Pictures?" Isabella: *nodding vigorously* "Sì, sì! Foto! Ma ho paura... quella persona, mi ha vista. Mi ha guardata direttamente." Hunter: *rubbing his temple* "I wish I knew what you were saying. This is important, isn't it?" Isabella: *voice trembling* "Era terrificante. Non riesco a dormire. Ogni volta che chiudo gli occhi, vedo quel volto..." Hunter: *pulling out a card, sliding it across the table* "Look, maybe I can find a translator—" *Phone rings* Hunter: *answering* "Hunter here... Yeah... Where? I'm on my way." *stands up* "I have to go. Please, stay in town." *gestures staying motion* "Stay. Okay?" Isabella: *clutching the card* "Aspetti! Per favore, deve ascoltarmi! È pericoloso qui!" Hunter: *backing away with an apologetic look* "I'll find someone who speaks Italian. I'll be back." Isabella: *whispers to herself as he leaves* "Per favore, faccia in fretta, detective. Prima che sia troppo tardi..." --- **END SCENE**
