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 ducked under the police tape, the worn leather of her shoes crunching against the gravel as she approached the scene. Her sharp eyes scanned the abandoned Tube station, taking in the chaos: uniformed officers canvassing the area, forensics techs dusting for prints, a body covered by a tarp on the platform. Harlow's gaze narrowed as she recognized a familiar face among the gathered crowd. "Kowalski, what are you doing here?" she called out, her voice clipped. Eva Kowalski startled at the sound, nervously tucking a stray curl behind her ear. "Detective Quinn. I...I was just passing through, I swear—" "Spare me the excuses." Harlow strode over, arms crossed over her chest. "This is a police investigation. You have no business being here." Eva swallowed hard, her green eyes darting around. "I know, I know. I was just...curious. I heard about the body and—" "And you thought you'd poke your nose where it doesn't belong?" Harlow cut her off, lip curling in disdain. "This isn't some academic exercise, Kowalski. A man is dead." "I understand that," Eva said quietly, adjusting the strap of her worn leather satchel. "I just...I thought I might be able to help. You know I have...unique expertise when it comes to these kinds of things." Harlow's jaw tightened. She knew all too well about Eva's so-called "expertise" — the young woman was far too deeply entrenched in the occult for Harlow's liking. But as much as she loathed to admit it, the girl's arcane knowledge had proven useful in the past. With a resigned sigh, Harlow gestured toward the covered body. "Fine. But stay out of the way and don't touch anything." Eva nodded gratefully and followed Harlow to the platform, where the forensics team was meticulously cataloging the scene. Harlow crouched beside the body, carefully pulling back the tarp. The victim was a middle-aged man, his face frozen in a rictus of terror. Harlow frowned, gently examining the body. There were no visible wounds, no signs of a struggle. Curious. "What have we got?" she asked the lead forensics tech, a young woman with a no-nonsense demeanor. "Cause of death is still unclear," the tech reported, tucking a stray lock of hair behind her ear. "No obvious trauma, no signs of poisoning. Tox screen is still pending, but initial observations suggest..." She trailed off, brow furrowing. "Suggest what?" Harlow prompted. The tech hesitated. "Well, it's just...the body temperature is significantly lower than it should be for the time of death. And there's a strange energy in the air, almost like..." She glanced nervously at Eva, who was standing a respectful distance away, observing the proceedings with a pensive expression. Harlow followed her gaze, then turned back to the tech. "Spit it out, Daniels." "Like...like something supernatural may have been involved," Daniels finished reluctantly. Harlow's jaw tightened. She should have known. Supernatural elements were precisely the kind of complication she didn't need. "Noted," she said tersely. "Keep me apprised of any new developments." As she rose to her feet, she caught sight of a familiar glint on the ground near the body. Bending down, she retrieved a small brass compass, its casing etched with protective sigils. Her eyes narrowed. "What's this?" Eva perked up, stepping closer. "Oh, that's fascinating. May I take a look?" Harlow held up a hand. "Not so fast, Kowalski. This is evidence." She examined the compass, watching as the needle spun erratically, seemingly drawn toward the body. Her frown deepened. "Any idea what this is?" she asked, glancing at Eva. The young woman studied the compass intently, her green eyes alight with curiosity. "It appears to be a Veil Compass," she murmured, almost to herself. "A tool used to detect supernatural energy." Harlow's brows rose. "The Veil Market, huh? That's quite a distance from here. What's it doing at this crime scene?" Eva worried her lower lip, considering. "Perhaps...perhaps the victim was involved in something supernatural. The Compass may have led him here, or drawn someone here to him." Harlow's jaw tightened. "So you're suggesting this was no ordinary murder?" "I..." Eva hesitated, then nodded slowly. "That's my best assessment, based on the evidence." Harlow regarded her for a long moment, then sighed heavily. "Of course it is." She tucked the compass into an evidence bag, her mind whirring. This was turning into a far more complicated case than she'd anticipated. Supernatural elements always made things messy. But if Eva was right, and there was more to this death than met the eye, Harlow would need to tread carefully. She glanced at the covered body, then back at Eva. "All right, Kowalski. Start talking. What can you tell me about this Veil Compass, and how it might be connected to our victim?" Eva perked up, eager to share her knowledge. "Well, the Veil Compass is a fascinating artifact. It's attuned to supernatural energy, and can be used to detect the presence of rifts, portals, or other anomalies." She paused, tucking a stray curl behind her ear. "If it was found at the crime scene, then it stands to reason that the victim was somehow involved with the occult. Perhaps he was investigating something, or was the target of a supernatural entity." Harlow's brow furrowed as she considered this. "So you're saying this could be more than just a simple murder. There could be...otherworldly forces at play." Eva nodded solemnly. "I'm afraid so, Detective. This case may be more complex than it first appears." Harlow sighed, pinching the bridge of her nose. Just when she thought her day couldn't get any worse. "All right, Kowalski. Start from the beginning. Tell me everything you know about the Veil Market and its connection to the supernatural." Eva straightened, her green eyes shining with anticipation. "Well, it all started three years ago, when I was doing research in the British Museum's restricted archives..."
