You are an expert novel author in the cozy mystery genre. Take the following details about characters/locations/... into account: <character name="Selvi"> Selvi is a 30-year old college student on a study abroad program. Born in India, she is fluent in Hindi and does not yet know any English. She enjoys landscape photography and is always seen with her camera. </character> <character name="Hunter"> Hunter is a 35-year old detective who is investigating a series of mysterious disappearances in the small town of Alborn, MN. He is a former marine and has a no-nonsense attitude. Hunter has no knowledge of Hindi, not even basic phrases. </character> <location name="Alborn, MN"> Alborne is a small town in the Midwest with a population of 3,000. It is known for its annual apple festival. </location>
User/Human
Write the following scene: Selvi is sitting at a cafe, looking at her camera. Hunter approaches her and asks her about a recent event in the town. She responds troubled and shaken in Hindi, and Hunter looks confused. They talk for a while, until Hunter gets a call and has to leave. Return the dialogue between Selvi and Hunter as a voice sheet: Selvi: "..." Hunter: "..."

Model response

AI
Selvi: यह सब कैसे हुआ? शहर के बीच-बीच में लोग गायब हो रहे हैं, मैं डर गई हूँ। Hunter: I don't speak Hindi. Could you tell me in English what happened here? What did you see? Selvi: हाँ, मैंने एक तेज़ आवाज़ सुनी और लोग अचानक भाग गए, फिर कुछ मिनटों में सब गायब हो गए। Hunter: Are you sure this is related to the disappearances? What else did you notice? Selvi: कैमरे में मैंने एक अजीब रोशनी देखी—हल्की सी चमक, फिर अंधेरा छा गया और लोग गायब हो गए। Hunter: A strange light? Do you have any footage of that light or any timestamp on the camera? Selvi: हाँ, कैमरे के LCD पर वह रोशनी साफ़ दिखी थी; मुझे लगता है यह कुछ संकेत था, पर मैं समझ नहीं पाई। Hunter: Stay safe. If you remember anything else, tell me. Hunter: I have to take this call.
