Harlow Quinn ducked under the yellow police tape and descended the rusted iron ladder into the darkness. The air down here tasted of wet copper and old decay. Her boots struck the concrete platform with a sharp click that echoed too far into the tunnel. She checked the worn leather watch on her left wrist. 03:14. The station had been sealed since 1992, yet the dust on the tiles looked disturbed. DS Miller stood near the far end of the platform, his flashlight beam fixed on a slumped figure against the peeling white tiles. He turned as Quinn approached, his face pale in the gloom. "Place is locked up tighter than a bank vault, Harlow. No signs of forced entry on the surface grates." Quinn stopped beside him and looked down at the body. A man in his thirties, dressed in a suit that cost more than her annual salary. No visible wounds. No blood on the tracks. "Cause of death?" "Paramedics called it a heart attack. No external trauma. Coroner wants him out before the morning rush starts above ground." Quinn crouched. Her knees cracked in the silence. She ran a gloved hand over the man's chest. The fabric of his jacket felt stiff, coated in a fine grey powder that didn't match the station dust. She rubbed the substance between her thumb and forefinger. It shimmered with a faint iridescence before vanishing into her skin. "He didn't walk down that ladder," Quinn said. She pointed to the ladder behind them. "Runners are clean. Dust is undisturbed on the rungs." Miller shifted his weight. The gravel crunched under his sole. "Could have come from the tunnel end. Maintenance crews use the tracks." "Tracks are electrified third rail. Power was cut an hour ago. Footprints would show in the grime." Quinn stood and swept her beam across the platform. The light caught something metallic near the dead man's right hand. She knelt again. A small brass compass lay palm up, as if placed there deliberately. The casing bore a patina of verdigris that looked centuries old. Etched into the face were protective sigils that hurt her eyes when she focused on them too long. "Evidence bag," Quinn said. Miller handed her a plastic bag from his belt. She slipped the compass inside without touching the glass face. The needle inside spun wildly before locking onto a direction deep into the tunnel, away from the ladder. "Looks like a antique. Probably dropped it when he collapsed." "Needle doesn't point north." "Compasses break, Harlow. Happens all the time." Quinn walked toward the tunnel mouth. The darkness swallowed her flashlight beam after ten metres. She stopped and listened. A low hum vibrated through the soles of her boots. It felt like standing next to a large generator, but the power was cut. "Feel that?" Miller joined her. He frowned and rubbed his arm. "Static electricity. Old tunnels get weird currents." Quinn turned back to the body. Her sharp jaw tightened. Eighteen years on the force taught her when a scene felt wrong. This felt like the night Morris died. Three years ago. Same lack of evidence. Same impossible location. She pushed the memory down. "Look at the shoes." Miller aimed his light at the dead man's feet. Italian leather loafers. Pristine. No mud. No scuff marks. "He walked through a sewer to get here and his shoes stay clean?" "Maybe he took a cab to the entrance and climbed down." "Ladder dust is three years thick. He would have left handprints on the rungs. I checked. Nothing." Quinn walked back to the body. She inspected the man's pockets. Empty. No wallet. No phone. No identification. Just the compass. She looked at the wall behind the head. Faint chalk marks lined the tiles. Geometric shapes interlocking in a pattern that defied symmetry. "Vandalism," Miller said. "Kids break in, draw graffiti, guy surprises them, heart gives out." "Chalk is mixed with bone ash. Smell it." Miller leaned in. He wrinkled his nose and stepped back. "Smells like burnt hair." "Someone opened a door down here." "There are no doors." Quinn tapped the compass through the evidence bag. The needle twitched. It wasn't pointing down the tunnel anymore. It pointed at the wall behind the body. "Help me move him." "We wait for the coroner." "Coroner isn't coming down here. Not until I say so." Quinn grabbed the body under the arms. Miller hesitated, then took the legs. They lifted the weight. The man was heavier than he looked. As they moved him, the chalk marks on the wall became fully visible. A circle, incomplete. A gap where the body had been leaning. "See that?" Quinn asked. "See what?" "The gap matches the curve of his spine. He wasn't slumping. He was blocking something." Miller set the legs down. He wiped sweat from his forehead with his sleeve. "You think someone pushed him against the wall?" "I think he was holding it shut." Quinn reached into her pocket and pulled out a magnifying lens. She examined the chalk lines. The lines weren't drawn on the surface. They were etched into the tile itself, deep enough to catch the light. "Tile is ceramic. You can't etch ceramic with chalk." "Acid," Miller suggested. "Acid would burn the grout. Grout is intact." Quinn stood up. She holstered the lens and checked her watch again. 03:28. The hum in the floor grew louder. A vibration rattled the loose change in her pocket. "Did you feel that?" "Train coming through on the Northern Line. Above us." "Northern Line doesn't run this deep. And the vibration is coming from the wall." Quinn stepped toward the etched circle. The compass in her hand grew warm. She could feel the heat radiating through the plastic bag. The needle spun faster, blurring into a grey disc. "Harlow, step back. We don't know what kind of gas buildup we're dealing with." "Gas doesn't etch tiles. Gas doesn't clean shoes." Quinn reached out and touched the wall where the chalk circle broke. The stone felt cold. Colder than the rest of the station. Her breath plumed in front of her face. Miller's breath did not. "Your breath," Quinn said. Miller stared at her. He exhaled. No cloud formed. "Temperature drop. Localised." Quinn pulled a multi-tool from her belt. She scraped the edge against the etched line. Sparks flew. The sound screeched through the tunnel, sharp and metallic. The needle on the compass stopped spinning. It pointed directly at the spot where her tool touched the wall. "Something is behind here." "Brick and mortar." "Look at the dust." Quinn shone her light on the floor around the body. The grey powder she found on the jacket lay in a perfect ring around the chalk circle. It didn't spread. It didn't mix with the station dirt. It sat on top like snow on asphalt. "Whoever he met came through the wall." Miller holstered his flashlight. He crossed his arms over his chest. "You're chasing ghosts, Harlow. Morris got himself killed chasing ghosts. Don't follow him." Quinn tightened her grip on the evidence bag. The brass casing dug into her palm. "Morris found something real. This proves it." "It proves a man died in a closed station. Nothing more." Quinn turned her back on him. She faced the wall. The hum vibrated in her teeth. She raised her flashlight and swept it over the ceiling. Cables hung loose. Water dripped from a pipe. The rhythm of the drips changed. Faster. Then slower. Like a pulse. "Listen." Miller listened. He shook his head. "Water pipes." "Pipes don't sync with a compass needle." Quinn placed her hand flat against the cold spot on the wall. The vibration travelled up her arm. It settled in her shoulder. A pattern emerged. Three short pulses. Two long. Three short. "Someone is knocking." Miller grabbed her shoulder. He pulled her back. "We are leaving. Now." Quinn shrugged him off. She kept her eyes on the wall. The cold spot expanded. Frost crept across the white tiles, branching out like veins. The chalk lines glowed faintly blue. "Get the camera. Record this." "I'm not recording fantasy." "Record it." Miller hesitated. He reached for the body cam on his uniform. He tapped the lens. The red light blinked on. "Happy?" "Keep it rolling." Quinn stepped closer to the frost. The compass needle locked steady. The heat from the device intensified. She could smell ozone and burnt sugar. The frost stopped spreading. It formed a shape. A door frame. No handle. No hinges. Just an outline of ice on ceramic. "Open it," Miller said. His voice shook. "Can't. Not from this side." Quinn looked down at the dead man. She rolled up his sleeve. His skin was pale, translucent. Veins showed black under the surface. Not blood. Something thicker. Something dark. "He didn't die of a heart attack." "Then what?" "Drainage." Quinn pointed to the man's wrist. Two puncture marks sat on the inside of the vein. Clean. Precise. "Needles," Miller said. "Too wide. Something drank from him." Quinn holstered the compass. She pulled out her notebook and sketched the chalk circle. Her pencil moved fast. She captured the sigils exactly as they appeared. The lines intersected at angles that made her head ache. "Send this to forensics." "They'll laugh." "Send it." Miller took the page. He folded it and put it in his pocket. He looked at the ice door. The frost began to melt. Water ran down the tiles, mixing with the grey powder. The powder hissed when the water touched it. "It's disappearing." "Everything disappears eventually." Quinn watched the water pool around the body's feet. The liquid turned red. Not bright red. Dark. Almost black. It flowed toward the tunnel drain. "Check the drain." Miller knelt. He shone his light into the grate. The water vanished into the darkness. No sound of it hitting the bottom. "Deep drop." "Too deep for a tube station." Quinn walked to the edge of the platform. She dropped a flare into the tunnel. It fell for five seconds before igniting. The red light revealed tracks that stretched into a void. No end visible. "Where does that go?" "Nowhere. It's a dead end." "Nothing is a dead end down here." Quinn turned back to the body. She knelt and closed the man's eyes. They felt gritty under her gloves. Like sandpaper. "Bag the hands. I want swabs from under the nails." Miller moved to comply. He pulled a swab kit from his bag. He scraped under the fingernails. The material came away black. It smelled of sulphur. "Matches the powder on the jacket." "Matches the dust on the ladder," Quinn said. She stood up. "He didn't climb down. He fell up." "Up?" "Gravity is wrong down here. Check the water flow." Miller looked at the puddle. The water flowed toward the wall, not the drain. It pooled at the base of the ice outline. "Capillary action," Miller said. "Defies gravity." Quinn checked her watch. 03:45. The hum stopped. The silence rushed in like a physical weight. The ice on the wall cracked. A hairline fracture appeared in the centre of the outline. "Did you hear that?" "Ice melting." "Ice doesn't crack when it melts. It cracks when it freezes." Quinn stepped back. She pulled her service weapon. She held it low by her side. Miller drew his too. They stood shoulder to shoulder. The fracture widened. A sliver of light appeared behind the wall. Not white light. Purple. Deep and violet. "Step back," Quinn ordered. Miller stepped back. His boot crunched on a piece of fallen tile. The sound echoed like a gunshot. The light behind the wall pulsed. It matched the rhythm of the knocking from before. Three short. Two long. Three short. "Same signal," Miller whispered. "Same signal," Quinn confirmed. She kept her eyes on the crack. The violet light grew brighter. The shadows in the tunnel stretched toward the wall. Long and thin. Like fingers reaching for the opening. "Ready?" Quinn asked. "For what?" "For whatever comes through." Quinn tightened her grip on the pistol. Her thumb rested on the safety. She waited. The crack widened another millimetre. The smell of burnt sugar intensified. It coated the back of her throat. She swallowed it down. "Stay behind me." Miller nodded. He adjusted his stance. His knuckles turned white on his grip. "Open fire if it moves." "Only if it threatens." "It already killed one man." "We don't know that yet." Quinn watched the light. It flickered. A shape moved behind the violet glow. Tall. Thin. Indistinct. The compass in her pocket grew hot enough to burn through her jacket. She ignored the heat. She kept her aim steady. The shape stepped closer to the crack. The light dimmed. The shadow became clearer. Shoulders. Head. Arms. Humanoid. "Contact," Quinn said. "Visual confirmed," Miller replied. The shape stopped. It stood still behind the wall. Waiting. "Make contact," Quinn said. "How?" "Ask it." Miller cleared his throat. He stepped forward. "Identify yourself." No answer. The shape remained still. The violet light pulsed once. "Ask it what it wants." "What do you want?" Miller asked. The shape raised a hand. It pointed at Quinn. The finger was long. Too long. Too many joints. "It's pointing at you," Miller said. "I see it." Quinn lowered her weapon slightly. She kept her eyes on the hand. The finger twitched. It beckoned. "Come here," Miller translated. "Or come through," Quinn said. The crack widened. The ice shattered. The wall dissolved into mist. The violet light flooded the platform. Quinn shielded her eyes. The heat vanished. The cold returned. The shape stepped onto the platform. It wore a suit identical to the dead man. Same shoes. Same height. "Duplicate," Miller said. "Replacement," Quinn corrected. The new man looked at the body on the floor. He looked at Quinn. His eyes were solid black. No whites. No irises. "Who are you?" Quinn asked. The man smiled. His teeth were sharp. Pointed. Like a shark. "Delivery," the man said. His voice sounded like two stones grinding together. "Delivery of what?" "The package." The man pointed at the compass in Quinn's pocket. "Give it back." Quinn kept her hand on her weapon. She did not reach for the compass. "Finders keepers." The man's smile widened. It stretched too far across his face. The skin tore at the corners. No blood came out. Only more violet light. "Not yours," the man said. "Prove it." The man took a step forward. The frost returned to the floor. It spread toward Quinn's boots. Miller fired a warning shot. The bullet passed through the man's shoulder. No hole appeared. The fabric healed instantly. "Ballistics ineffective," Miller shouted. "Noted," Quinn said. She kept her aim on the head. The man stopped moving. He tilted his head. He listened to something Quinn could not hear. "Time," the man said. "Time for what?" "Time is up." The man vanished. The violet light snapped off. The platform plunged into darkness. Quinn's flashlight flickered on. The body was gone. The chalk circles were gone. The ice was gone. Only the grey powder remained on the floor. "Where did he go?" Miller asked. "Same place the body went." Quinn holstered her weapon. She reached into her pocket and pulled out the compass. The needle spun wildly. It pointed at Miller. "Why is it pointing at me?" "Because you're next." Quinn clipped the compass to her belt. She turned toward the ladder. "We leave. Now." "Leave the evidence?" "Leave the trap." Quinn started climbing. Her boots found the rungs. She pulled herself up. Miller followed. They reached the surface. The air smelled of rain and exhaust. Normal city smells. Quinn checked her watch. 03:55. Ten minutes had passed. "Look at the grate," Quinn said. Miller looked down. The grate was rusted shut. Painted over. Undisturbed for years. "We were never down there," Miller said. "We were." Quinn touched her jacket. The burn mark from the compass remained. A perfect circle on the fabric. "Proof," Quinn said. "Proof of what?" "Proof that Morris wasn't crazy." Quinn walked to her car. She opened the door and sat inside. She placed the compass on the dashboard. The needle settled. It pointed north. True north. "See?" Miller said. "Working normally." "For now." Quinn started the engine. She watched the compass. The needle twitched. Just once. Then it stayed still. "Drive," Quinn said. Miller got in the passenger seat. He buckled up. "Where to?" "Home. We sleep. Then we hunt." Quinn put the car in gear. She pulled away from the curb. The streetlights flickered as they passed. One by one. In sequence. Following the car. "Did you see that?" Miller asked. "See what?" "The lights." "Old wiring." Quinn kept her eyes on the road. She gripped the steering wheel. Her knuckles matched the white of the lane markers. The compass sat on the dash. It began to hum. Low and steady. "Turn it off," Miller said. "Can't." "Throw it out." "No." Quinn drove faster. The hum grew louder. It matched the engine noise. The city lights blurred past. London slept. Quinn did not. She watched the needle. It began to turn again. Slowly. Away from north. Toward the rearview mirror. "Someone is following us," Miller said. "No one is there." "Check the mirror." Quinn looked. The road behind was empty. No headlights. No taillights. Just darkness. "Then why is the needle turning?" "Because we are being tracked." Quinn pressed the accelerator. The car surged forward. The hum in the compass matched the speed. Faster. Louder. Higher pitch. "Get down," Quinn ordered. Miller ducked. Quinn swerved the car. A shadow passed over the roof. Too low for a bridge. Too solid for a cloud. "Contact," Quinn said. "Where?" "Above." Quinn slammed on the brakes. The car skidded. She spun the wheel. The car faced the opposite direction. The road was empty. The compass needle pointed straight up. "It's on the roof," Miller whispered. "Stay inside." Quinn opened the door. She stepped out. She looked up. Nothing. Just the night sky. Stars. Clouds. No shadow. "Get back in," Miller said. Quinn walked around the car. She ran her hand over the roof. The metal was cold. Freezing. Frost coated the paint. In the shape of a handprint. "See?" Quinn said. "I see." Quinn wiped the frost away. It melted into water. It ran down the window. It formed letters. RUN. "Who wrote that?" Miller asked. "Whoever owns the compass." Quinn got back in the car. She locked the doors. "Drive," Quinn said. Miller drove. He kept his eyes on the road. He did not look at the compass. He did not look in the mirror. "Where to now?" "Away from here." "How far?" "As far as the needle points." Quinn watched the compass. The needle stopped spinning. It pointed toward Camden. Back to the station. "Circle," Quinn said. "Always a circle." Quinn leaned back. She closed her eyes. She listened to the hum. It sounded like a voice. Whispering. Words she could not understand. Language she did not know. "Morris," Quinn said. "What?" "His voice." Miller said nothing. He kept driving. The city passed by. Dark. Silent. Waiting. The compass hummed louder. The needle trembled. It wanted to move. It wanted to lead. "Let it," Quinn said. "Let what?" "Lead us." Miller turned the wheel. The car followed the needle. Toward the underground. Toward the market. Toward the truth. Quinn opened her eyes. She watched the road. The frost returned to the windshield. It spread from the edges. Closing in. "Keep going," Quinn said. "Into the dark," Miller said. "Into the light." Quinn touched the compass. It burned her fingers. She did not pull away. She held on. The heat spread through her hand. Up her arm. Into her chest. It felt like memory. It felt like loss. It felt like Morris. "Almost there," Quinn said. "Almost where?" "Where it starts." The car slowed. The needle stopped. They sat in silence. The engine idled. The hum stopped. The frost cleared. The streetlights turned on. One by one. Ahead of them. A path. "Go," Quinn said. Miller drove. They entered the light. The darkness stayed behind. For now. The compass sat on the dash. Silent. Still. Waiting. Quinn watched it. She waited too. She knew it would move again. It always did. She gripped the wheel. She prepared for the turn. The road curved. Downward. Into the earth. "Here," Quinn said. "Here," Miller confirmed. They descended. The air grew thick. The smell of copper returned. The station waited below. The gates opened. They drove through. The gates closed behind them. No sound. No echo. Just the hum of the engine. And the compass. "Stop," Quinn said. Miller stopped. They sat in the dark. The headlights illuminated the platform. The body was gone. The chalk was gone. The ice was gone. Only the compass remained. And the needle. It pointed at the tunnel. "End of the line," Miller said. "Start of the line," Quinn corrected. She opened the door. She stepped out. Her boots struck the concrete. Click. Click. Click. She walked toward the tunnel. Miller followed. They disappeared into the dark. The headlights faded. The compass glowed. A faint blue light. In the darkness. Guiding them. Forward. Always forward.
