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 stairs leading into the abandoned Tube station smelled of damp concrete and something else—something metallic and wrong. Detective Harlow Quinn descended with military precision, her worn leather
watch
catching the dim light as she checked the time. 3:17 AM. The call had come in at 2:42, reporting an "unusual death" in a location that wasn't supposed to exist on any official map. "Quinn!" Sergeant Barker's voice
echoed
up from the platform. "Down here. You're not going to believe this one." Quinn rounded the last corner and stepped onto the platform. The space was eerily preserved, advertisements from the 1940s still clinging to the tiled walls, their colors faded but visible in the harsh glow of police work lights. In the center of the platform, a white tent had
been erected
, and within its translucent walls, Quinn could make out the outline of a body. "What've we got?" Quinn asked, her voice low as she pulled on latex gloves. Barker, a young detective with too much enthusiasm and not enough wariness, met her at the tent entrance. "Male, approximately thirty-five years of age. No wallet, no ID. Found by maintenance workers doing an unauthorized survey. Cause of death appears to be... well, that's where it gets interesting." Quinn ducked inside the tent. The body lay face up, eyes wide open and staring at nothing. His mouth was
slightly
agape, and his skin had an unnatural pallor that had nothing to do with death. But it was what surrounded him that caught her attention. Scattered around the body were items that made no sense—ancient coins that glimmered with an unnatural luster, small vials of liquid that
seemed to
shift colors when viewed from different angles, and fragments of parchment covered in symbols that Quinn had never seen before. "Robbery gone wrong?" Barker suggested. "He had something valuable, someone wanted it?" Quinn shook her head, her sharp jaw tightening as she knelt beside the body. "No forced entry wounds. No defensive injuries. Look at his hands." She
gently
lifted one of the victim's hands. "No dirt under the nails, no bruising on the knuckles. He didn't fight back." "Maybe he knew his attacker?" "Or maybe there was no physical attacker at all." Quinn's eyes scanned the body again, lingering on something around the victim's neck. She
carefully
moved aside the collar of his shirt to reveal a thin leather cord with a small brass compass hanging from it. The compass casing had a patina of verdigris, and its face
was etched
with protective sigils. "Weird timepiece to bring to a robbery," Quinn murmured,
carefully
unfastening the cord. As she held the compass in her palm, the needle
began to
spin wildly before settling, pointing not north but toward the far end of the platform. "What is it?" Barker asked, leaning closer. "I don't know." Quinn dropped the compass into an evidence bag. "But it's not a standard compass." She stood up, her gaze sweeping the crime scene again. Something was off. The evidence was too
perfectly
arranged, too
deliberately
placed. It
was staged
—meant to tell a story that wasn't true. "The coroner's初步 report suggests heart attack," Barker said, consulting his notes. "Given the lack of physical trauma, that makes sense. Maybe he was down here illegally, got into something shady, and his heart gave out." Quinn didn't respond. Her attention had
been drawn
to a figure standing at the edge of the police tape—a young woman with curly red hair and round glasses, clutching a worn leather satchel full of books. She
was talking
to one of the constables, her freckled complexion pale in the artificial light. "Who's
that?" Quinn
asked, nodding in the woman's direction. "Eva Kowalski. She says she's a research assistant from the British Museum. Claims she has information that might be relevant to the case." Quinn's
eyes narrowed
. "In the middle of the night? At an abandoned Tube station?" "That's what I said. But she insisted it was urgent." Quinn walked toward the tape, her bearing drawing immediate attention. "Ms. Kowalski?" The woman turned, her green eyes widening
slightly
as she took in Quinn's presence. "Detective Quinn? I've read about your work." "I
doubt that," Quinn
said dryly. "What are you doing here?" Eva
nervously
tucked a strand of hair behind her left ear, a gesture that seemed instinctual. "I received an anonymous tip about this location. Something about supernatural activity." Quinn's expression didn't change, though her mind
was racing
. Three years ago, her partner DS Morris had died investigating similar claims—claims that had led them to an abandoned warehouse and something that Quinn still couldn't explain, something that had defied all laws of nature and physics. "Supernatural activity," Quinn repeated, her voice flat. "I know how it sounds," Eva said
quickly
. "But I study ancient texts—rituals, artifacts, objects that don't fit our conventional understanding of the world. And what's in there—" she nodded toward the tent "—those items, they're not just valuable antiques. They're enchanted." "Enchanted," Quinn said, the word tasting foreign on her tongue. "They're from the Veil Market," Eva insisted, lowering her voice. "It's a hidden supernatural black market that moves locations every full moon. This station is one of its occasional sites." Quinn studied the young woman, looking for signs of deception, of attention-seeking. She found none—only genuine fear and conviction. "And how would someone gain entry to this... market?" Quinn asked
carefully
. Eva hesitated, then reached into her satchel and pulled out a small token carved from bone. "You need one of these. A bone token. They're not easy to come by." Quinn's eyes fixed on the token. It matched symbols she'd seen on the parchment fragments inside the tent. "Who runs this market?" "No one knows for sure. It's shadowy, transient. Dealers come and go. But there are rumors—about a clique that controls the most valuable items, that uses the market as a front for more dangerous activities." Quinn's mind
was connecting
dots that hadn't existed minutes ago. The compass that pointed to supernatural energy, the bone token for entry, the enchanted items scattered around the body. This wasn't a random robbery or a simple heart attack. "Thank you, Ms. Kowalski," Quinn said, her voice clipped. "I'll need your contact information. And that token—it's evidence now." Eva
reluctantly
handed over the bone token, along with a card with her details. "Please be careful, Detective. The people involved in this—they're not like ordinary criminals." Quinn nodded curtly and returned to the tent, where Barker
was waiting
. "Well? What did the conspiracy theorist have to say?" he asked, only half-joking. "She's not a conspiracy theorist," Quinn said, her mind working rapidly. "And this wasn't a heart attack." "It's what the coroner said." "The coroner hasn't seen this." Quinn pointed to a barely visible mark on the victim's wrist—a small symbol that matched the sigils on the compass. "And these items—they're not random. They're specifically arranged in a pattern. Look." Quinn knelt again, tracing a line in the air with her finger. "The coins form a circle. The vials are positioned at what would be the cardinal points. The parchment fragments are placed in a sequence that tells a story—a ritual." Barker frowned. "So what are you saying? This was some kind of cult meeting gone wrong?" "I'm saying this was murder," Quinn said firmly. "And whoever did it used something we don't understand—something that left no physical trace but killed this man just as surely as a bullet to the head." She stood up, her gaze fixed on the far end of the platform where the compass needle had pointed. "We need to search the entire station. Every tunnel, every alcove. I want to know what that compass was leading him to." "And if we don't find anything?" Quinn's jaw tightened. "Then we're dealing with something that can hide in plain sight. Something that doesn't want to be found." She thought of DS Morris, of the unexplained circumstances of his death, of the supernatural origins she had only begun to suspect three years too late. This time, she wouldn't miss the signs. This time, she would find the truth—no matter how impossible it seemed.
