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.

It is known for its annual apple festival. </location>
User/Human

Return the dialogue between Maria and Hunter as a voice sheet: Maria: "..." Hunter: "..."

Model response

AI
Maria: *sitting quietly at an outdoor cafe table in Alborn's town square, fiddling with her camera lens, her expression distant* Hunter: Excuse me, miss? I'm Detective Hunter with the Alborn PD. Mind if I ask you a few questions? You were at the apple festival last night, right? Did you see anything unusual around the time those festival workers went missing? Maria: *looks up startled, her eyes widening with unease, speaking rapidly in Spanish, voice trembling* ¿Qué? No entiendo... Anoche, en el festival, vi a un hombre extraño cerca de los árboles. Estaba discutiendo con alguien, y luego... desaparecieron. ¡Parecía sospechoso! Llevaba una chaqueta oscura, y creo que tenía algo en la mano, como un arma o... no sé, me asusté y me fui. Hunter: *blinks, scratching his head, clearly lost* Uh... I'm sorry, what? English? Do you speak any English? Festival... last night... strange man? *mimes holding a camera* You take pictures? Can you show me? Maria: *shakes her head, more agitated, gesturing with her hands as if describing a scuffle, her voice rising slightly* ¡No hablo inglés! Por favor, es importante. El hombre... alto, con barba. Los trabajadores... se fueron con él, creo. ¡Llamen a la policía! *points urgently at her camera screen, showing a blurry night photo of shadowy figures near apple trees* Hunter: *leans in, squinting at the camera, frustration building but trying to stay calm* Okay, slow down. Alto... beard? *pulls out his notebook, sketching roughly* Like this? Workers... gone? *nods encouragingly, though obviously puzzled* This photo—it's helpful. Can you come to the station? We have a translator maybe? Maria: *nods vigorously, but her hands are shaking as she clutches the camera* Sí, sí, iré. Pero es peligroso... ese hombre, lo vi mirándome. *trails off, glancing nervously over her shoulder* Hunter: *sighs, rubbing his temple* Alright, dangerous... got it. Just stay put for a sec— *his phone buzzes loudly in his pocket* Damn. Hold on. *answers the call* Hunter here. Yeah? Now? *pauses, face hardening* On my way. *hangs up, turning back to Maria apologetically* Look, I gotta run—another lead. Stay here, I'll send someone for you. Gracias? *attempts a mangled pronunciation* Maria: *nods shakily* De nada... tenga cuidado. Hunter: *gives a thumbs-up and hurries off, muttering under his breath* What the hell was that?
