Rain sheeted across Camden High Street and turned the pavement into a ribbon of black glass. Headlights smeared into long, greasy streaks in the puddles. Harlow Quinn hunched deeper into her coat and watched the man across the road adjust his hood. Short. Olive skin. Curly dark hair flattened by the downpour. The Saint Christopher medallion flashed once at his throat when a bus roared past and washed him in white light. Herrera. He touched the scar along his left forearm as he checked his watch, sleeve dragged back for a second. That same nervous tic from the photos. The worn satchel thumped against his hip as he stepped off the curb. Her thumb rolled along the grooves of her own leather watchband. Eighteen months of dead ends and half-truths wrapped themselves around his name. Off-the-books medic. The clique’s quiet paramedic who never left a trace. The traffic light flicked red. He cut between a stopped taxi and a lorry. Her hand already closed around the radio on her belt. "Control, this is Quinn. I have Tomás Herrera, Camden High Street, heading north. Requesting—" Herrera glanced back. Their eyes met through the sheet of rain. His widened, the warmth in them iced over in an instant. He bolted. Harlow dropped the radio. "Tomás! Police. Stop!" Her boots hit the road hard, water exploding around her ankles. Horns blared as she sliced between bumpers. A driver leaned out his window and swore at her. She shoved off the bonnet of a hatchback and sprang after him. He moved fast for a man hauling a satchel. He wove through a knot of tourists huddled under a shop awning. An umbrella snapped in her face. "Watch it!" "Police!" Her voice ripped out of her throat, sharp as glass. "Move!" Bodies parted. A teenage girl yanked her friend out of Harlow’s path, eyes wide. Her feet hammered the slick pavement, muscles burning, lungs drawing in cold air laced with exhaust and fried food. Herrera glanced back again. His hood had slipped. Rain pinned dark curls to his forehead. His mouth twisted. "You don't want this, detective!" "Keep running," she called, breath cutting the words short, "and you'll find out exactly what I want." He veered left, away from the main drag. Past the last chain restaurant, past neon signs and kebab shops, into a narrow side street that stank of wet brick and spilled beer. Harlow followed. The city closed in. Flats loomed above, windows yellow and blind. The only light came from a single security lamp, its halo distorted by the rain. Herrera’s trainers slapped against the uneven stones, echo bouncing off the walls. Her own footfalls chased his rhythm. He hurdled a stack of empty crates. She ploughed straight through them. Plastic cracked. A crate tangled her ankle. She stumbled, caught herself on a graffiti-tagged wall, shoved off and kept going. "Stop!" The word tore loose, raw. He didn't. He darted past overflowing bins and a back door propped with a beer keg. Somewhere behind the door, music thumped, muffled and distant. The smell—stale beer, bleach, something sweet and rotting—rolled out in waves. Rain soaked through her shirt. Her leather watchband squelched against her skin. Her fingers went numb around the weight of her service pistol at her hip. He cut right at the end of the alley. She slid, boots fighting for grip, shoulder slamming into the corner of the wall. Pain flared down her arm. She pushed off and turned. The street beyond was near empty. A shuttered shopfront. A row of dark townhouses. In the distance, Camden’s lights glowed, blurred by the storm. Straight ahead, a rusted iron gate blocked off a descending set of stairs, brickwork cracked around the arch. Disused Tube entrance. She had clocked it in passing a dozen times. Boarded since before she joined the Met. Metal sign above, the old Underground roundel faded and pockmarked with rust. Herrera sprinted straight for it. "Dead end, Tomás!" Her voice bounced down the narrow way. He didn’t slow. The gate should have stopped him. It had a heavy chain twisted through the bars, a padlock thick as her thumb. He drew something from his pocket. Small. Bone pale. It gleamed wetly in his hand under the security light. He pressed it against the chain. Metal hissed. Harlow’s breath snagged. A sound like steam and whispering breath rolled over the rain. The chain sagged, links darkening as if they rusted in fast motion. The padlock buckled. The gate wobbled open half an inch under his push. "No way," she muttered. He threw her one last look over his shoulder. His chest rose and fell fast. "This is not your ground, detective." "You're carrying contraband," she fired back, rain dripping from her lashes. "Where you run, my ground follows." His jaw clenched. "Then you better pray you can still walk back up." He slipped through the gap and vanished down the stairs. The gate creaked as it swung shut behind him. Harlow reached it two heartbeats later. The chain hung slack, heavy and cold when she grabbed it. Solid. No break, no scorch, no mark. The padlock’s surface felt rough, flaking under her thumb. Orange rust dusted her skin. Her radio crackled behind her. "Quinn, you still with us? Status on Herrera?" She ignored it. Water beaded on the gate’s bars. Her reflection broke into fractured segments in the black glass of the stairwell below. No light. Nothing but shadow and the endless drip of water. Her fingers tightened. Unfamiliar territory. Doors that opened for bone-white tokens and shut again as if nothing had touched them. Morris had stood in a doorway like that. Different alley, different city block, same thin slice of darkness in front of him. Three years ago. Rain just as heavy. His shoulders relaxed as he turned to look back at her. "Don't follow," he had called, grin wide. "Paperwork can't take another miracle." He never walked back out. Her throat closed around the memory. The radio hissed again. "Detective Quinn, respond. Do you require assistance?" Assistance. A patrol car and two uniforms who would crank that padlock, find it stubborn and ordinary, and log the whole thing as a wild goose chase in the Camden rain. Herrera gone. Another ghost in a file. She pressed the transmit button without lifting the radio. "Control, suspect entered a building. I’m making enquiries. Stand by." "Copy, Quinn. Keep your radio live." She clipped it back to her belt. The rain softened here, as if the alley itself shielded the gate. Water still fell, but the sound dampened. The street noise on the main road faded to a distant hum. The air tasted old. Dust and copper and something faintly sweet that didn't belong to the city. Her hand found the gate’s edge. She pushed. It didn’t move. She set her shoulder into it. Rust groaned. The chain strained, metal grinding against metal. For a second, she felt resistance hold like bone under a boot. Then the gate shifted. An inch. Two. Cold breathed up from below, not the damp chill of a normal underground stair, but an absence, as if the air itself didn’t want to exist down there. Gooseflesh marched up her arms under the soaked fabric. A thin glow flickered deep below, not the steady yellow of Tube lights, but a shifting, many-coloured pulse, like candle flames seen through warped glass. Harlow drew her pistol and thumbed off the safety. The movement slid into place out of habit. Her hands stayed steady. The only tremor lived in the tight muscles around her jaw. She leaned in. A faint murmur rose from below. Voices, dozens at least. Bartering tones. Laughter. The clink of glass. Another sound threaded through them, low and constant, like a distant animal growl or an industrial generator. She couldn't pin it down. Herrera had disappeared into that. A sane detective would call it. Seal the area. Wait for a team. Wait for daylight. Wait for someone to draw a map of the unknown for her. Her boot already rested on the first step. "Tomás Herrera," she called, voice dropping in the shaft. "You are under arrest for obstruction and suspected trafficking of controlled substances. Come back up now." Silence answered. Then a single shout echoed faintly, distant enough that she couldn't catch the words. Laughter followed it. She muttered under her breath. "You wanted this case, Harlow. Stop flinching." Her watch ticked against her skin, the drumbeat of seconds clear under the hush. Rain tapped on metal above. The city felt very far away. The gate stood half-open. The rusted chain coiled like a dead snake around the bars. The doorway yawned black. Her breath went out in a slow stream. She tasted concrete dust and old oil on her tongue. "Control," she spoke into the radio, not taking her eyes from the light pulsing below, "signal might drop. I’m going underground." Before the response crackled back, she slipped through the gap, squared her shoulders to the dark, and descended into the hidden station.
