**Scene** In the warm, sunlit corner of Alborn’s only café, where the smell of cinnamon apple muffins hung sweetly in the air, Selvi sat hunched over her camera. The small town’s annual apple festival had ended days ago, yet the images on her memory card still troubled her. She scrolled through the photos with trembling fingers, the quiet click of the buttons the only sound at her table. Heavy footsteps approached. Detective Hunter, broad-shouldered and serious in his flannel jacket, stopped beside her. He had noticed the young woman taking pictures all over town and hoped she might have captured something useful. The conversation that followed was… difficult. **Voice Sheet** Hunter: "Pardon me, miss. I’m Detective Hunter. I understand you were taking landscape photos during the apple festival last weekend. We’re investigating a disappearance that happened that night. Did you see anything unusual—anyone acting strange, anything out of place?" Selvi: "मैं बहुत डरी हुई हूँ… मैंने देखा था। एक आदमी अचानक गायब हो गया, जैसे हवा में घुल गया। मैं चिल्लाई भी नहीं पाई। अब नींद नहीं आती। ये तस्वीरें… इनमें कुछ है, लेकिन मैं समझ नहीं पा रही क्या करना चाहिए।" Hunter: "…Right. I don’t speak a word of that. I’m guessing Hindi? Do you understand English at all? English? We have a missing person. Missing. It’s important." Selvi: "हिंदी… हाँ, सिर्फ हिंदी। आपकी भाषा मुझे नहीं आती। वो आदमी अचानक से चला गया। मेरा कैमरा था हाथ में, लेकिन जब देखा तो वो वहाँ नहीं था। मुझे अभी भी उसका चेहरा याद आता है। डर लगता है।" Hunter: "I’m getting about one word in ten. Look, I can see you’re upset. If you saw something, I need to know. Can you write it down? Write? Or maybe there’s a student at the college who speaks—" Selvi: "मेरा फोन भी नहीं काम कर रहा ठीक से। मैं अकेली हूँ यहाँ। अगर आप पुलिस वाले हैं तो मदद कीजिए ना। वो गायब हुआ आदमी… शायद और लोग भी गायब होंगे। मैंने और भी अजीब छायाएँ देखीं।" Hunter: "This isn’t working. I’ll find a translator and come back. Just… stay in town. Don’t go wandering with that camera until we talk properly." Selvi: "क्या कहा आपने? ट्रांसलेटर? हाँ, कोई हिंदी बोलने वाला लाइए। मैं सब बता दूंगी। लेकिन जल्दी कीजिए… मुझे लगता है वो जो कुछ हुआ, वो खत्म नहीं हुआ है।" Hunter: "Hold on— I have to take this call. It’s the station. We’ll continue this later. Stay safe, miss." *(Hunter steps away, phone already to his ear, leaving Selvi staring after him, camera still clutched tightly in her hands.)*
