Detective Quinn’s torch flared against damp brick, water dripping from a fractured pipe overhead. She stepped off the embankment platform and into the tunnel, boots echoing on cracked tile. The stench of rust and stale breath of air pressed in, as though the old Tube station remembered every soul who’d vanished down here. Her watch face glinted in the beam—leather band worn soft, its hands still ticking with steady precision. Uniformed Patel crouched by a chalk circle scrawled across the concrete floor. He drew a slow finger around its edge, pausing where the line curved into a rune she didn’t recognise. “Heard it’s ritual,” he offered, back straightening. “Gut says cult activity.” Quinn regarded the circle. Faint streaks of crimson stained the grainy surface. No gun lay nearby. No weapon, no casing. Only the corpse—man in his thirties, face upturned, jaw slack and eyes glassy. Quinn crouched, boots brushing the chalk. “Ritual, or someone wanted us to think it’s ritual.” She tilted her head, searching the arc of that circle. “No glove prints. No sign of disturbance beyond this.” Patel knelt opposite, flicking his flashlight around the station walls. “They’d carve it deeper if they wanted to keep him here,” he said. “This looks amateur—some kid playing at summoning demons.” A drip of water spattered on the body’s outstretched palm. Quinn crouched lower, traced a scar across the man’s wrist—clean slice, angled just so. She brushed away a bead of blood with a fingertip, watching it pool again. “He didn’t draw the circle himself,” she observed. “He was placed inside.” Patel fished a small phial from his jacket, capped with cork. He held it to the light. “We found this by the eastern wall. Looks like acid residue.” He uncorked it, cupped the neck to waft the fumes. “Chemical burn. Not supernatural.” Quinn slid a knee closer, elbow brushing the man’s coat. She tilted the body’s head, studying the scorch ring at the collarbone. No soot remained on the lapel. Fingertip pressed the flesh—crumbled like paper. “Burn marks but no fire. And that phial never touched him.” She tapped a fingertip on the concrete where the acid must’ve pooled. “If someone stood here, they’d have etched this tile into powder. Yet it’s intact.” A flash of red curls appeared at the tunnel mouth. Eva Kowalski slipped in, satchel bumping her hip, fingers already tugging at curly strands by her ear. She knelt on the opposite side of the chalk circle and squinted at the rune. “These symbols match an abbreviated ward,” she said, voice pitched just above a whisper. “Found a mention in a 14th-century manuscript—salt-based circle meant to repel something.” Patel frowned. “A ward against what? Ghosts? Demons?” Eva retrieved a leather-bound notebook, flipped to a dog-eared page. “Something not from our world,” she murmured, tracing the lines of an identical rune. “Protector circles keep things in.” She tapped the chalk. “Problem’s someone tried to seal this spot.” Quinn knelt between Patel and Eva. She scraped a fingertip over the chalk. No powder, only hard ridges. She pulled her thumbnail across the edge. A flake broke free—tiny metallic shards glittering under the torch. She held them aloft. “Not chalk,” she declared, eyebrow lifting. “Metal filings, coated in calcite. They bolted a seal here, not drew one.” Patel rubbed his temple. “So he barricaded himself?” Quinn whisked excess dust away, revealing jade-green moss clinging to the runic lines. She ran a fingertip through a patch. It left a faint stain on her glove. “Moss doesn’t grow on fresh cement,” she noted. “Someone inserted an energy source.” She glanced at Eva. “What if he tried to trap something? But it got out.” Eva’s lips parted. She balanced her glasses on the bridge of her nose and peered closer at the moss. “Ordinary moss would blacken in acid. This glows under low light. Phosphorescent. It feeds on residual magic.” Quinn pressed her jaw. She reached into her coat and withdrew the brass compass they’d bagged near the body. Verdigris mottled its casing, protective sigils etched in a ring around the glass face. She flipped the lid. The needle spun, jittering against the sigils, then locked and trembled toward the tunnel’s far wall. She closed it and pocketed the tool. “It points to a rift,” she said. Patel straightened, arms folding. “We’re chasing fairy tales now.” Quinn stood, torch beam following the compass direction. The wall opposite showed no sign of damage—just smeared graffiti and seepage stains. She pressed her palm against cracked mortar. Beneath her fingers, she felt a warmth, a faint hum that reverberated through her bones. “This way.” Water pooled at her boots, swelling around her heels. She crouched by a hairline fissure, light catching a translucent glow inside. She scraped the edge with her thumbnail. Moisture welled and trembled like lamp oil. She dropped the shard of mortar into a evidence pouch without looking away. Eva edged closer, voice hushed. “He wasn’t hunting demons. He was guarding a breach. That circle wasn’t a trap for him—it was a prison for something else.” Patel scanned their faces, uncertainty flickering in his eyes. “So…” He swallowed. “What killed him?” Quinn knelt, tracing the chalk-fired mold of salt crystals now cracked and flaked. She flicked dirt from her glove. “He paused the seal. Maybe he thought they’d freed him. Maybe he miscalculated. Either way, he died standing guard.” She rose, her silhouette tall against the tunnel’s gloom. “We need samples of the filings, the moss, the mortar. Lab analysis on the acid phial, too. Someone engineered a ward. Someone breached it.” Eva rose, satchel thudding. She tucked hair behind her ear and nodded. Patel reached for his radio, voice low and clipped, calling in evidence teams and lab specialists. Quinn stepped back from the fissure and allowed Patel to cordon off the area with yellow tape. Her torch caught the edge of the crack again—tiny crystal veins glinting. She closed her eyes for a heartbeat, measured her breath, then opened her notebook and jotted a single line: “Guard collapsed under pressure of energy leak.” She snapped it shut, sliding the compass back into her pocket. Above them, the tangled wires of the Tube station sagged. Water dripped from the tracks. The circle on the floor lay broken in places, shards of salt and metal filings scattered by Patel’s boot. Quinn crouched one last time, gathering a loose flake between gloved fingers and dropping it into her evidence bag. Then she stood and met Patel’s eyes in the dim light. “Case file’s changed,” she stated. “This was never a cult murder. It was a containment breach.” She turned back to the fissure, torch beam steady, ready for the answers the lab would bring.
