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.

Detective Harlow Quinn stepped off the last rung of the rusted ladder and into the dimly lit expanse of the abandoned Tube station beneath Camden. Her boots echoed against the cracked tiles, the sound swallowed by the oppressive silence of the underground. She adjusted the worn leather watch on her left wrist, a habit she had developed over years of service, and scanned the area with sharp, brown eyes. The Veil Market, a hidden supernatural black market, had chosen this forsaken place for its latest incarnation. The market moved locations every full moon, and tonight, it had been the scene of a crime. Harlow's salt-and-pepper hair, cropped close to her scalp, gave her an air of military precision, a stark contrast to the chaos that usually accompanied her investigations. Eva Kowalski, her childhood friend and an occult researcher, stood near the center of the station, her curly red hair a bright beacon in the gloom. Eva's round glasses caught the faint light from the flickering bulbs overhead, and she clutched her worn leather satchel tightly, as if it were a lifeline. She was tucking a strand of hair behind her left ear, a nervous habit Harlow recognized all too well. "Quinn," Eva called out, her voice echoing off the tiled walls. "Over here." Harlow approached, her eyes narrowing as she took in the scene. A body lay sprawled on the ground, surrounded by a circle of salt and strange symbols drawn in chalk. The victim, a middle-aged man with a gaunt face, stared sightlessly at the ceiling. His skin was an unnatural shade of gray, and his mouth was frozen in a silent scream. "What's the story?" Harlow asked, her voice steady despite the unease gnawing at her gut. Eva adjusted her glasses and glanced at her notes. "The victim is Thomas Granger, a known dealer in enchanted goods. He was found like this about an hour ago. No signs of a struggle, no obvious cause of death." Harlow knelt beside the body, her sharp jawline set in a determined line. She examined the symbols, recognizing some as protective sigils, others as wards against dark magic. "These markings... they're meant to keep something out. Or in." Eva nodded, her green eyes wide with concern. "That's what I thought too. But there's something else." She reached into her satchel and pulled out a small brass compass, its casing covered in a patina of verdigris. "I found this near the body. It's a Veil Compass, crafted by a Shade artisan. It points toward the nearest supernatural rift or portal." Harlow took the compass, noting the protective sigils etched into its face. The needle quivered, pointing toward a darkened tunnel at the far end of the station. "So, he was trying to find a rift. But why?" Eva hesitated, tucking her hair behind her ear again. "There's a rumor that Granger was involved in something big. Something dangerous. He might have been trying to escape." Harlow stood, her mind racing. The evidence didn't add up. Granger had been a dealer, not a practitioner. He wouldn't have known how to use the sigils or the compass. Someone else had set this up. Someone who wanted to make it look like Granger had been dabbling in dark magic. "Eva, who else knew about this market's location?" Harlow asked, her voice low. Eva frowned, thinking. "Only a select few. The market's organizers, some of the more trusted dealers. It's a closely guarded secret." Harlow's eyes narrowed. "Then someone on the inside is involved. Someone who wanted Granger out of the way." Eva's eyes widened. "You think it was a setup?" Harlow nodded, her mind piecing together the puzzle. "Granger was lured here, made to look like he was involved in something he wasn't. The real question is why." Before Eva could respond, a figure emerged from the shadows. Detective Sergeant Mark Harris, Harlow's colleague, approached with a grim expression. His tall frame and broad shoulders seemed to fill the space, and his dark eyes were filled with suspicion. "Quinn," Harris said, his voice a low rumble. "What have you got?" Harlow briefed him on their findings, watching his reaction closely. Harris listened, his jaw tightening as she explained her theory. "That's a stretch, Quinn," he said finally. "Granger was a known dealer. It's not hard to believe he got in over his head." Harlow shook her head. "It's too convenient. The sigils, the compass, the location. It all points to a setup." Harris crossed his arms, his gaze hard. "And who do you think is behind it?" Harlow glanced at Eva, then back at Harris. "Someone with access to the market's secrets. Someone who knew Granger would be here." Harris sighed, rubbing the back of his neck. "Alright, let's say you're right. How do we prove it?" Harlow looked at the compass in her hand, the needle still pointing toward the darkened tunnel. "We follow the trail. The compass will lead us to the rift, and maybe to our answers." Harris nodded reluctantly. "Fine. But we do this by the book. No shortcuts." Harlow smirked. "Wouldn't dream of it." As they prepared to follow the compass's lead, Harlow couldn't shake the feeling that they were being watched. The Veil Market was a place of secrets and shadows, and she knew that uncovering the truth would be no easy task. But she was determined to see it through, no matter the cost. Eva fell into step beside her, her satchel clutched tightly. "Be careful, Harlow. This place... it's dangerous." Harlow glanced at her friend, a rare softness in her eyes. "I know, Evie. But we have to find out what happened. For Granger, and for everyone else who might be caught in this web." With that, they stepped into the darkness, the compass guiding their way. The tunnel seemed to stretch on forever, the air growing colder with each step. Harlow's senses were on high alert, every sound and shadow scrutinized. As they rounded a corner, the compass's needle began to spin wildly. Harlow held it steady, her heart pounding. "We're close." Eva's breath hitched. "Do you hear that?" Harlow strained her ears, catching a faint, otherworldly hum. It was a sound she had heard only once before, the night she lost her partner, DS Morris. The memory sent a chill down her spine, but she pushed it aside. She had a job to do. They emerged into a cavernous chamber, the walls lined with ancient runes that glowed with an eerie light. In the center of the room stood a stone archway, its surface shimmering like liquid silver. The rift. Harlow approached cautiously, the compass's needle now pointing directly at the archway. "This is it." Eva's eyes were wide with awe and fear. "What do we do now?" Harlow took a deep breath, her mind racing. "We need to find out who used this rift and why. There has to be a clue here, something we missed." As they searched the chamber, Harlow's gaze fell on a small, ornate box hidden in the shadows. She picked it up, examining the intricate carvings. It was locked, but she could feel a faint pulse of magic emanating from within. "Eva, can you open this?" Harlow asked, handing the box to her friend. Eva nodded, her fingers deftly working the lock. After a moment, it clicked open, revealing a collection of papers and a small vial of dark liquid. Harlow sifted through the papers, her eyes narrowing as she read. "These are contracts. Deals made with supernatural entities. Granger's name is on several of them." Eva's face paled. "He was in deeper than we thought." Harlow held up the vial, the liquid inside swirling ominously. "And this... it's a binding agent. Used to trap souls." Harris stepped forward, his expression grim. "So Granger was making deals with the supernatural. But why?" Harlow's mind raced, piecing together the puzzle. "He was trying to gain power, to protect himself. But someone found out and used it against him." Eva's eyes widened. "The rift. They used it to summon something, to take Granger out." Harlow nodded, her jaw set. "And we're going to find out who." As they prepared to leave the chamber, Harlow couldn't shake the feeling that they were on the brink of something much larger. The Veil Market held many secrets, and she was determined to uncover them all. For Granger, for Morris, and for everyone else caught in the web of the supernatural. With the compass in hand and her friends by her side, Harlow Quinn stepped back into the darkness, ready to face whatever lay ahead.
