# Voice Sheet: Café Encounter **Hunter:** "Excuse me, miss? Mind if I sit down for a moment? I'm Detective Hunter with the county sheriff's office." **Selvi:** "..." *looks up from camera, hesitant* **Hunter:** "I'm investigating some incidents in town. Were you by any chance near the old mill yesterday evening? Someone matching your description was seen in the area." **Selvi:** "मुझे समझ नहीं आ रहा... मैं वहाँ थी, हाँ, लेकिन मैंने कुछ देखा... कुछ बहुत अजीब।" *(I don't understand... I was there, yes, but I saw something... something very strange.)* **Hunter:** "I'm sorry, I don't... Do you speak English?" **Selvi:** "English? नहीं, नहीं... बहुत कम।" *(No, no... very little.)* *shakes head, visibly distressed* **Hunter:** "Okay, okay. The mill?" *makes a gesture like a building* "You were there?" **Selvi:** "हाँ, हाँ, mill। वहाँ एक आदमी था... वो अचानक गायब हो गया। बस ऐसे ही। मैं बहुत डर गई थी।" *(Yes, yes, mill. There was a man... he suddenly disappeared. Just like that. I was very scared.)* *mimics something vanishing with her hands* **Hunter:** "Disappeared? Someone disappeared?" *leans forward* "Can you show me? On your camera?" **Selvi:** *scrolls through camera, hands trembling, shows him a blurry night photo* "देखिए... यहाँ वो था... और फिर..." *swipes to next photo* "...कोई नहीं।" *(Look... he was here... and then... no one.)* **Hunter:** "Jesus. That's..." *studies the photos intently* "I need copies of these. Can I—" *Hunter's phone rings* **Hunter:** "Hunter here." *pause* "What? When?" *stands abruptly* "I'm on my way." *to Selvi* "I have to go. Stay in town, okay? Don't leave." *makes a staying gesture* "Stay. Here. Town." **Selvi:** "Stay? ठीक है... मैं यहीं रहूँगी।" *(Okay... I will stay here.)* **Hunter:** *places his card on the table, taps it* "Call. If you remember anything." *mimics phone to ear* **Selvi:** *nods slowly, clutching her camera* "बहुत अजीब जगह है ये..." *(This is a very strange place...)*
