The bin lid caught my shoulder, a clang and a burst of white, and he ran. I swallowed rust and chased. Puddles threw cold up my shins. He slipped, recovered, vaulted a bollard. The street breathed diesel and cheap chips. I cut the corner, toes tasting slick cobbles, and saw the back of his cracked leather jacket flick right, then right again, then through a clutch of club kids under a flickering green sign. I brushed a stencilled raven as my palm smacked the brick, took the corner hard and gained half a step. "Police," I said. No need to waste breath. He glanced once. Bad eyes, jumpy, ferret quick. He bolted into traffic. A van horn split the night, brakes screamed, and he threaded between bumper and barrier with the luck of fools. I vaulted the median, hot pain like a wire along my left shoulder where the lid had kissed bone. My old leather watch caught the light as I pumped my arms, the minute hand jerking towards an hour I did not like. He ducked into a loading bay and a metal shutter rolled up a rib. I slid under and tasted the sour of damp cardboard. Stale beer, smouldered weed, old piss. My boots splashed through rainbow gutters of oil. He took the stairs two at a time. I took them three. He had a head start and he knew it. He threw a glance back, saw my eyes, and put everything into the next flight. At the alley mouth he shot out and took Kingsway north. I felt the map in my feet, shortcuts I knew and the ones he hoped I did not. Rain pinned my clothes to my skin. He shouldered past a woman with a takeaway bag and it burst, rice and sauce and a spray of nuts skittering like shot. My fingers brushed his jacket and missed. He sniffed the air like a rat near the tide and found the smaller street, old brick peeling under the weight of new glass. He ran harder. He turned by a closed barber's, scissored signage blunt in the wet, and headed for the canal. Camden. He wanted shadows and a way down. My tongue tasted copper again. I adjusted my pace to match his rhythm, waited for fatigue to uncurl his fingers from his own lungs. When it did, I went for him. "Stop running, Ash," I said, because I had done my homework. "We have your prints on the Soho scene. I have a witness who knows your name." He did not stop. He cut under an iron bridge and jumped the low chain. I hit the chain with my thigh, saw stars, and rolled with it. Up, breath in, keep him on the rope. He put his hands on a rusted gate and hauled. The kind of gate that did not lead to anywhere you wanted your badge to show. "Do not go down there," a voice said behind me, calm and close, the voice of a man who had held screaming in his hands until it bent into a lullaby. I did not look back. Ash ran through and into a long, shallow ramp that nose-dived into black. A damp breath came up from the deep like a beast in sleep, human feet scuffed on old concrete. His shoulder clipped brick and left a smear, dark and thin. The gate hit the lock again, a click that sounded like the end of things. I hit the gate with my palm. A dull ache sank into the heel of my hand. Not my first locked door. I stepped back, drew breath, and drove the boot sole to the hinge pocket. Third kick, the bolt quivered but held. I drew my baton, ran a quick glance over the mechanism, and found a better weakness. "Quinn," the voice said, closer. "You do not want to crash that door." "Move," I said. I turned my head enough to cut his face out of the gloom. Early thirties, olive skin, hair cut close, a curl at his brow brewing some ill-advised empathy. His eyes held mine with the steadiness of someone who had watched people break and kept them whole. I knew the face before I put a name to it. The Saint Christopher medallion at his throat gave it away faster than the scar that licked along his left forearm. "Herrera," I said. "Detective," he said. "Walk away." "This is not for you," he said. "Not with your badge." My hand closed on cold iron. "He went down. I am going after him." "Do you carry a coin," he said, and his eyes dipped to my pocket where my warrant card rode like a shard of glass. "A bone." I remembered a half-dozen witness statements that turned to steam when we tried to take them to paper. The market that was here and not, a place that sold things you did not name. I had thought they were talking in circles to dodge charges. I had thought a lot of things before Morris bled out on Queen's Row with nothing mortal to blame. "What coin," I said. He lifted his hand and there was a disc the size of a jam lid, slick white, porous like a sponge that had learned to be hard. Holes drilled not quite evenly. It hung from a dirty red shoestring. He held it like a surgeon held a needle. He did not wave it. He did not tempt me. He let me look. "Entry," he said. "And exit." "Give it to me." "You will not like what waits under the city," he said. "You will bring a gun to a place that bans fire. You will carry law to a place that sells it by the ounce." "Spare me the poetry," I said, and levelled the baton at the gate seam. "We can talk about it after I have my man." "I can open it for you," he said. "I can walk you down. One condition." "Which is." "You listen when I tell you to stop." I chose. I heard the skid of shoes below, the ghost of it on slick concrete. The sound of a man who did not believe anyone followed. I turned the baton, slid it into the gap, pried the lock enough to kiss the edge of surrender, then stepped back. "Open it," I said. He pressed the bone to a round steel plate set into the brick like an old lift button. Bone kissed metal, a hungry hiss, and the lock rolled. The gate popped on old hinges. Air crawled over my knuckles. Herrera lifted the chain, used his shoulder to ease the gate so it did not scream, and tucked the bone back under his shirt where Christopher lay. He looked at my face in that clinical way, reading pulse in the eyes. "Do not show your badge," he said. "Do not name a name. If someone offers you salt, refuse with your right hand. If someone calls you friend, walk." "Walk where." "Where I tell you." I went down. Steps, broad and old, swept around like a staircase that could not remember it had ever been a friend. The air smelled of wet stone and the kind of incense that stained fingers yellow. Pipes rattled in the brick, water coughed. We turned a corner and the city let go. Light reached up as a series of bruises, purple and green, swimming on the old tiles. A line of painted signs, A to Z, some in alphabets that were not taught in our schools, some in pictograms that moved if you looked too long. It was quiet the way the moment before a heart stops is quiet. Then the sound began. Not a roar. Not a shout. The hum of coins in pockets. The wet silk of a pack of cards being bridged. The crisp snap of wool felt on glass. A woman's laugh caught on the rim of a bottle. Someone slicing something that hit the board with a soft plop. The dull smack of palm to palm, a transaction completed with more fingers than I saw. The platform used to hold train carriages of light. Now it held stalls. Tables of cracked leather piled with vials. Cloth hung between pillars, heavy and dark, sewn with little mirrors that winked like eyes. The old board with numbers, seven, eight, nine, lay on its side and someone had painted a fox over it with cobalt and salt. The third rail flashed awake in the corner of my eye and went dark again. Ash was here somewhere, his fear like a thread I could pull. I took it in my hand and moved. I passed a place that sold knives, but the knives looked tired of cutting and wanted to saw souls loose. I passed a table of maps. The man minding them had cow brown eyes and lids that blinked too slow. He tapped a place near Blackfriars with a nail that was not human. I did not stop. "Tea leaves, lovely," said a woman with a green scarf full of tiny bones. "Two quid to see who waits at your door. Five to open it." "You call that a bargain," I said without looking, and my eyes slipped past a boy with stitched mouth who juggled glass. He caught one by thinking and put it back into his hand. "Bluefire for old aches," a man sang. "Moon-dropped, cut clean. Third bottle free for the lady with the army walk." "Later," Herrera said to him, and the man nodded and wrote a mark in a book. "Left," Herrera said to me. "He cut through the card rooms." "You cannot see him," I said. "I can hear the fight in your feet," he said. "That is what he hears too. So he will go where feet mean less." Ash slid through a curtain, brushed a string of iron keys that hung like chimes without sound, and entered a space boxed with green baize and smoke. The players at the table did not look up, faces sunk in their cards, eyes set like amber, a dealer who shuffled with one hand while the other poured a measure from a blue bottle into his ear. I tracked the tail of Ash's jacket through shoulders. Herrera kept a finger on the back of my coat like he was tethering a balloon. "You let him buy here," I said. "I let people get well," he said. "And worse. I do not sell either. I sew." "You lost your licence because you do not listen," I said. "Tonight you can practice obedience." "I listen," he said. "I listen more than you do." "Keep up," I said, and pushed. Ash sensed me. I felt the prickle of his fear turn and point like a weathercock. He bolted, slipped into a stall that traded in powdered metals, knocked a stand of silver paper onto the floor. For a breath the aisle filled with a blur of light as the paper fell, each sheet catching the shimmer of the bulbs above and sending it back stuttered. I hit it with my boot, slid, corrected. He slammed through a narrow door with a sign in chalk, thirty seconds only. I went for the jamb. "Do not," Herrera said, sharp enough to cut. I looked. He shook his head. He pointed at the chalk. He put three fingers up, then tapped them to the metal plate. Not a rule you broke twice. I swallowed what I wanted to do to the door and nodded once. We went around. "How often does this move," I said as we hit another curve. "Full moon," he said. "Sometimes half if there is trouble. They like deep water and deep time. Tonight they like Camden because you can drown at the end if you misstep." "Charming," I said. He steered me through a corridor of cages. Things looked back at me through bars. One shape might have been a dog with too many joints. Another might have been a man without a face and more heartbeats than bodies tend to have. I did not show my badge. I did not say police. A woman with a velvet patch over one eye lifted it to show nothing at all and asked if I preferred it alone or with company. I moved. Ash cut through a crowd gathered at a table where sticks of cinnamon burned with a noise like rain. He reached the old track bed and turned, thinking to lose me in the dark. He ran the beam of a cheap torch ahead and saw the curve of the tunnel and the thin line where the sleepers gave way to black water. He kept to the catwalk. I caught up. "Ash," I said, and he spun. He had a blade in his hand. Not big, not old, a practical little rectangular Sheffield whittling knife with a red handle. I had seen knives like that in old men's pockets. This one thrummed like a wire when he held it wrong and the thrumming sang in the wet air. "Stay back," he said. "You cannot touch me here." "I can arrest you anywhere," I said. "Drop the toy." "It cuts blood oaths," he said. "You think it will not cut skin." "We both know that blade owes you nothing," I said. "Put it away. We talk. Or you run, and you face whatever waits in that dark. Guess which will be kind." His eyes skipped to the side. He saw Herrera. For a second he thought of trying to use him as a lever and threw that thought away. Not quick enough. "You stitched my arm two months ago," Ash said to Herrera. "You told me to stay off the powder." "You did not listen," Herrera said. "None of us do," Ash said, and his mouth twitched, a private joke with himself that did not reach his eyes. He reached into his pocket with his free hand and came out with a little brown bottle the size of a thumb. "No," I said. He cracked it on the rail. Vapour uncoiled. Thick and sweet, like burnt sugar rotting, it slid over the catwalk and reached for my face with sticky hands. My lungs pulled back like spooked horses. I took a step into the edge of it and felt my chest tighten, my vision skew. Herrera yanked me sideways into the scallop of a maintenance alcove. The vapour found the space and pooled like a creature under a chair. "Hold your breath," he said. "Count seven." I did, and it put nails into the muscles of my throat. The sweet turned bitter, copper dragged a finger up the roof of my mouth. I let the breath out, took a smaller one, and tasted the back of a hospital, the day I sat on a plastic chair and listened to blood drip. I did not think of Morris. I thought of now. Ash ran. He used the confusion to vault a gap where sleepers had been torn out and someone had not put them back. He reached the other side and his footing went wrong, one foot splashed, the other skidded, and he pinwheeled with the grace of the desperate. He found the wall and steadied and he laughed once, panting. He turned left, not right, which was the mistake I had bet he would make. I pushed out of the alcove. We took the catwalk, wet metal under boot, a cold wind that did not come from anywhere sensible tickling my ear. There was a sound building under the noise of the market. A hum like the skin of a drum touched lightly, then harder. The air changed pitch. The old tunnel began to glow a little, as if someone had written light into the bricks and was tracing the line with a slow finger. Herrera looked at the third rail like it had whispered something filthy. "We need to clear the track," he said. "Now." "That is not a train," I said, and I did not mean it to sound like a question. "It is the market's carriage," he said. "They call it the shuttle. You do not want to ride that if you have not paid." "I will not be paying," I said. Ash reached a metal door with slashed paint. He threw a glance back, saw me see him, and tried the handle. It turned. Someone had left it warm and waiting. He shoved. The door hit a chain looped on the inside and bounced. He swore and dug fingers up and through the gap, groping for the catch. Behind me the hum climbed the scale and hit a human note. People on the platform had gone quiet. In that silence the market took a breath. "Ash," I said, and the baton slid into my hand like it lived there. "Drop the knife." He turned with the knife low and stupid and came at me. You learn to love that mistake. I stepped in, set my weight like I had been taught, and tapped the inside of his wrist. The blade clinked, fell, kissed the rail, and sparked once with a mean little blue. His hand closed on my jacket and we both went sideways. Our boots scrabbled, metal shrieked. He found purchase, shoved, and I felt the catwalk leave beneath my back. For an instant the world gave up on me. A cut of black water waited at my spine. Herrera's hand locked in my collar and yanked me back so hard the stitch of my coat screamed. My shoulder tore a song out of me. I rolled and came up on one knee, baton between us, Ash's face two feet away. He looked like a man who had burned his last bridge and was peeing on the ashes. He found the knife again with his left, grinned without joy, and then something big hit the far end of the tunnel. Light blew down the line, pale and wrong, the colour of a bruise you could hear. Hair rose along my arms. The market's shuttle rounded the bend without wheels, a long black shape edged in glass, windows full of faces that did not blink. The pressure of it pushed wind ahead like a fist. The stalls closest to the edge snapped their cloth tight. Bottles rattled. The boy with the stitched mouth dropped a ball and did not even try to catch it. "Move," Herrera said. Ash looked at the door, at me, at the train that was not a train. He made his choice. He raised the knife and went at my throat. I took the strike on the baton, wood clapped metal, and sparks spat like seeds. He shoved his shoulder into my ribs. I felt the rail's heat on my calf and the nothing of the drop just behind me. The air tore at us as the carriage bore down, silent and loud in the way bad dreams scream. Hands grabbed my coat from behind again, more than one this time, sudden and imprecise, and a voice sang out from the platform, high and pleased. "No fire, no steel, no law," it said. "Enforcers to track three." Black coats peeled off from the edges of the crowd, masks like old station clocks covering their faces, brass hands for eyes, long nightsticks already rising. Ash looked up at them and went white. He tried to back off me, then tried to use me as a shield, then could not decide. The shuttle hit the nearer marker with a flare of light that turned the damp air into cut glass. We stopped breathing because the air had left. "Detective," Herrera said, and something in his voice had left softness behind. I twisted, shoved Ash hard into the wall, and his head snapped back with a dusty thud. The knife flew. It landed on the third rail and lit like a star. He reached for me again, dropped his hands as the current hummed under his finger bones, and the masks closed in with the steadiness of men who never ran. The shuttle roared into the station mouth, no engine, no driver, windows full of a hundred eyes. The closest enforcer lifted his nightstick, etched runes catching the wrong light, and brought it down as I lifted mine to meet it.
