You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

Rain hammered down on the streets of Soho, turning the cobblestones into a slick, treacherous path. Detective Harlow Quinn's breath came in sharp bursts, each exhale a puff of mist in the cold night air. Her worn leather watch, a relic of her years on the force, ticked steadily against her wrist, a metronome to her pursuit. She rounded a corner, her sharp jaw set in determination, eyes scanning the dimly lit alleyways for any sign of her quarry. Ahead, a figure darted through the shadows, the brief flash of a Saint Christopher medallion catching the light from a flickering streetlamp. Tomás Herrera. She'd been tailing him for weeks, convinced he was the key to unraveling the web of supernatural activity that had ensnared the city. Her partner's death still haunted her, a specter that drove her to the edge of obsession. She couldn't let Herrera slip through her fingers now. The Raven's Nest loomed up ahead, its distinctive green neon sign casting an eerie glow over the rain-soaked street. Quinn's eyes narrowed as she saw Herrera push through the bar's heavy wooden door. She quickened her pace, her boots splashing through puddles, and reached the entrance just as the door swung shut behind him. Inside, the bar was a haven of dim light and murmured conversations. Old maps and black-and-white photographs adorned the walls, giving the place a timeless, almost nostalgic feel. Quinn's eyes adjusted quickly to the gloom, and she spotted Herrera weaving through the tables toward the back of the room. She followed, her movements precise and controlled, her senses on high alert. Herrera disappeared behind a bookshelf, and Quinn's heart skipped a beat. She approached cautiously, her fingers brushing against the spines of the old books. A hidden mechanism clicked, and the bookshelf swung open to reveal a narrow passageway. She slipped through, the door closing silently behind her. The passageway led to a staircase that spiraled downward, the air growing cooler and more oppressive with each step. Quinn's mind raced. She'd heard rumors of an underground market, a place where the supernatural and the illicit intertwined. If Herrera was heading there, it meant he was deeper in this world than she'd realized. At the bottom of the stairs, a heavy iron door barred her way. She hesitated for a moment, then pushed it open, stepping into a cavernous space that buzzed with activity. The Veil Market. Stalls lined the walls, selling everything from enchanted trinkets to banned alchemical substances. The air was thick with the scent of incense and the hum of whispered deals. Quinn's eyes scanned the crowd, searching for Herrera. She spotted him near a stall selling bone tokens, his olive skin and short curly hair unmistakable. He was speaking with a vendor, his scarred left forearm visible as he gestured animatedly. Quinn moved closer, her heart pounding in her chest. As she approached, Herrera glanced over his shoulder, his warm brown eyes widening in recognition. He turned and bolted, weaving through the throng of market-goers. Quinn cursed under her breath and gave chase, her military precision guiding her through the chaos. Herrera led her through a maze of stalls and narrow passageways, the market's layout shifting and changing as if it had a mind of its own. Quinn's breath came in ragged gasps, her muscles burning with exertion. She couldn't let him escape. Not now. They burst into a wider chamber, the ceiling arching high above them. Herrera skidded to a halt, his eyes darting around for an escape route. Quinn slowed, her hand resting on the grip of her service weapon. "Herrera!" she called out, her voice steady despite the adrenaline coursing through her veins. "Stop running. We need to talk." Herrera's eyes flicked to her, then to the exits. "You don't understand, Detective," he said, his voice tinged with desperation. "This isn't what you think." Quinn took a step closer, her gaze unwavering. "Then explain it to me. Help me understand." Before Herrera could respond, a group of figures emerged from the shadows, their faces obscured by hoods. Quinn's hand tightened on her weapon, her instincts screaming danger. The leader of the group stepped forward, a bone token dangling from a chain around his neck. "This is not your place, Detective," the leader said, his voice low and menacing. "Leave now, and you might live to see another day." Quinn's jaw clenched. She couldn't back down, not when she was so close to the truth. But the odds were against her, and she knew it. She glanced at Herrera, who was watching her with a mixture of fear and determination. "Go," Herrera said quietly. "I'll handle this." Quinn hesitated, her mind racing. She could fight, but it would be a losing battle. Or she could retreat, regroup, and find another way to uncover the truth. She took a step back, her eyes never leaving Herrera's. "I'll be watching," she said, her voice firm. "This isn't over." With that, she turned and walked away, her heart heavy with frustration and resolve. The rain had stopped by the time she emerged from the market, the city streets glistening under the streetlights. She would find another way. She had to. For her partner, for the city, and for herself.
