# Voice Sheet: The Café Interview **Setting: A small café on Main Street in 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 her camera, startled* "Scusi? Non capisco..." Hunter: "I'm investigating some incidents in town. Were you here last Tuesday evening? Near the old mill?" Isabella: *eyes widening with recognition at "Tuesday"* "Martedì? Sì, sì... martedì sera. Ho visto qualcosa di terribile. C'era una figura nell'ombra, vicino al mulino. Una donna gridava, poi... silenzio. Nient'altro che silenzio." Hunter: *frowning, leaning forward* "I'm sorry, I don't... Do you speak English? English?" Isabella: *shaking her head, visibly troubled* "Mi dispiace, non parlo inglese. Quello che ho visto... mi ha spaventata molto. La donna, è scomparsa così velocemente." Hunter: "Okay, I'm getting nothing here. Uh... you saw something? Saw?" *mimics looking with his hand* Isabella: *nodding vigorously* "Sì! Ho visto! Ho visto!" *clutches her camera* "Ho delle foto, ma erano troppo lontane, troppo scure..." Hunter: "Photos? On the camera?" *points at her camera* Isabella: *pulls the camera close protectively, then hesitantly shows the screen* "Guardi... qui. L'ombra. Non so cosa sia." Hunter: *squinting at the dark image* "I can barely make anything out. Look, I really need to—" *Hunter's phone rings* Hunter: *answering* "Hunter here. ...What? Another one? I'm on my way." *stands abruptly* "I have to go. Stay in town, okay? Town." *gestures around, then points down* "Stay." Isabella: *looking confused and frightened* "Cosa? Dove va? Ho bisogno di aiuto! Per favore, non ho nessuno qui che parli italiano!" Hunter: *already walking away, turns back briefly* "I'll find a translator. Translator. Someone who speaks..." *waves hand vaguely* "...whatever that is. Italian? Just... stay put." Isabella: *calling after him* "Aspetti! Per favore!" *slumps back in her chair, murmuring to herself* "Che cosa sta succedendo in questa città?" --- **End Scene**
