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.

The relentless London rain slashed through the neon-lit streets of Soho, streaking the pavement with reflections of glowing signs and turning umbrellas into a kaleidoscope of shimmering colors. Detective Harlow Quinn, her sharp jaw set in determination, navigated the slick sidewalks with practiced ease, her eyes trained on the figure darting through the crowds. Her quarry: a young man she suspected held the key to a string of supernatural incidents that had baffled the Metropolitan Police for months. Harlow's keen gaze followed the hunched form of her suspect, ducking through the swarm of tourists and locals. In a city teeming with life, the chase was a chaotic ballet of near-misses and deft maneuvers. Quinn's long strides ate up the ground, her eyes narrowing at every turn, determined not to lose sight of her target. The rain-soaked hair, closely cropped, spoke of a no-nonsense attitude, while the worn leather watch on her wrist ticked in military precision, marking the seconds of the pursuit. Tomás Herrera, the man in question, glanced over his shoulder, his warm brown eyes widening at the sight of the detective on his trail. A former paramedic with a knack for slipping into and out of shadows, he knew the dangers of being caught. But the needle-like drops of water, piercing his olive skin, were the least of his worries. The chase led them to the heart of Soho, where the smoky glow of The Raven's Nest shimmered in the damp night air. Thomas slipped through the distinctive green neon sign, knowing full well it was a well-known haunt for the underground supernatural community. A place the likes of which his pursuer would not dare enter without good reason. Harlow hesitated at the threshold, the rain now drumming a steady beat on her shoulders. The choice before her was clear: she could call for backup, risk her suspect slipping through her fingers, or she could venture into the shadowy depths of the Nest, where the rules of the mortal realm did not apply. Her determined eyes, a storm brewing within their brown depths, spoke of the decision she'd made in an instant. She stepped inside. The bar's interior, dimly lit by candlelight, flickered with shadows cast by old maps and photographs, giving the space a mysterious aura. The patrons, a mix of creatures from the supernatural realm, eyed the new arrival with curiosity, their bodies poised for quick action should they need to flee or fight. Tomás, his breath coming in short gasps, thrust himself into the secret back room hidden behind a bookcase, its entrance already ajar. He spared a glance at the Saint Christopher medallion around his neck, a talisman of protection and a reminder of his past, before plunging into the innermost sanctum. Quinn noticed the subtle shift in the crowd as she surveyed the room. The detectives honed instincts sensed the retreat of her quarry into what was likely a private meeting space. With swift precision, she made her way towards the bookshelf, passing tables of half-finished drinks and half-heard conversations in a mix of languages. Every step echoed in the silence that had fallen over the bar; all eyes now followed the detective, wondering if she knew the rules of this game. As Harlow reached for the book that concealed the entrance to the secret room, a low growl reverberated from within, sending a shiver down her spine. The growl was followed by a snarl, the sound of metal scraping leather, and then, the unmistakable hiss of a blade slicing through air. Harlow's hand paused in mid-reach, her mind processing the sounds that hinted at a confrontation. This was her suspect, she was sure of it, likely now in the throes of a trade or an exchange. The detective had learned from DS Morris, her fallen partner, that an uninvited interruption into the dealings of the supernatural world was not to be taken lightly. For a fleeting moment, Harlow considered backing away, waiting for backup, but the memory of Morris' unsolved disappearance steeled her resolve. She couldn't risk losing Tomás, not if he held answers about the underworld her partner had stumbled upon. With a swift pull, she opened the hidden doorway, the collection of old novels giving way to reveal a dimly lit room filled with swirling smoke. A swift scan of the chamber confirmed her suspicions: Tomás was pressed against the far wall, flanked by two creatures, their faces distorted by shadows, while a hooded figure stood across from them, an ornate dagger glinting in their hands. Time seemed to slow as the detective's eyes locked with Tomás'. In that moment, a lifetime of secrets, regrets, and hopes passed between them. Tomás' scar, a reminder of past perils, seemed to glow in the muted light, as if it held the answer to some great enigma. "Silas," Quinn's voice cut through the tension, her tone as sharp as the daggers being wielded. "Stand down." The hooded figure, the apparent ringleader, turned with a snarl, baring pointed teeth that couldn't quite hide a sardonic smile. "Well, well, well," Silas purred, his voice dripping with a mix of menace and humor. "If it isn't the detective who can't stay in her lane." "I'm here for the suspect," Harlow stated, her eyes flicking to Tomás, still pinned against the wall, his face a mask of determination. "No other business with you." Silas laughed, a chilling sound that sent a ripple through the smoke-filled air. "Detective, dear, you're in my territory now. This is the Veil Market, and the price of admission isn't up for negotiation." Quinn's heart hammered in her chest as she processed the implications. The Veil Market, an urban myth among law enforcement, was a supernatural bazaar that moved locations with each full moon. And the price of admission? A bone token, something this rogue detective knew nothing about. Without taking her eyes off the other occupants of the room, she slowly removed her left glove, exposing the intricate tattoo of a raven that spiraled from her wrist to her elbow. "This is an official Metropolitan Police operation. Step aside, or I'll have every creature here in irons by sunrise." Tomás couldn't hide the flicker of hope that flashed across his eyes at the mention of the police. He knew the potential repercussions of the supernatural community clashing with the mortal world. Yet he was under no illusions, having spent enough time in the shadows to understand that rules were relative in this hidden world. Silas cocked his head, his amusement turning to curiosity. "A lone detective, wandering into my territory with empty threats and an inkling of magic. What can you possibly hope to accomplish here, Detective Quinn?" Harlow didn't blink, her gaze unwavering. "I've come for Tomás Herrera and the truth behind a series of mysterious crimes plaguing this city. I suggest you step aside and let me do my job." The creature behind Tomás tightened his grip, his breath hot against Tomás' neck. "Boss, if it's all the same, I don't mind taking a walk to the Helheim Gates with this cop." But Silas waved him off, his eyes never leaving Quinn's. "The detective has braved my den, confronted my clan. I can't very well refuse her request without causing an international incident now, can I?" He turned to Tomás. "You, young Herrera, owe the detective a debt. Consider this your chance to repay it." The tension in the air snapped like a rubber band, leaving an expectant silence in its wake. Harlow's eyes flicked to Tomás, who returned her gaze, his posture relaxing ever so slightly. Silas stepped forward, his shadow dancing against the walls. "Consider this a one-time courtesy, Detective. Next time you find yourself down this rabbit hole, remember: you're not in Kansas anymore." Detective Harlow Quinn nodded, her eyes never leaving his, as she backed out of the secret room, Tomás' stare burning into her back. She knew better than to let the underworld mark her as an easy target. As she retraced her steps through the bar, the low murmurs of the patrons grew louder. In the rain-soaked streets outside, Quinn's mind raced, processing the encounter. One thing was clear: the further she ventured into this world, the greater the danger, but she'd vowed to see this through, whatever supernatural forces she might unearth. The chase had led her down a path with no clear end, and the detective's inner turmoil mirrored the city's constant ebb and flow. One truth rang clear above the din: Harlow Quinn was in uncharted territory, and not even her sharp instincts could foresee the consequences of her quest.
