"Stop. Bag stays shut." Harlow dropped from the platform and hit the ballast hard enough to bite through her soles. Grit snapped under her weight. The Scenes of Crime tech froze, gloved hands hovering over an open evidence pouch like a schoolboy mid-theft. "Detective Quinn?" DS Callum Sharpe peered over the edge, lean frame outlined by the dead platform lamps. "We have one body and a load of theatre. Fancy candles. Bloke bled out like a bad Hamlet." Harlow ignored him. She crouched beside the sheeted shape between the rails and peeled the plastic back from the chest down. Copper stung her nostrils. Blood. Recent. The man's shirt had been opened cleanly to the sternum and turned back with care. A narrow cut ran across his ribs. Not a slash. A line you could draw with a ruler. Someone had wiped him, then repainted him. Her fingers hovered a hair above the skin, sense of temperature, texture, remembering the way heat died. Above them, the old station stretched like a throat. Tiles flaked from curved walls, white gone nicotine and peeled, hand-painted adverts trapped in another century and another idea of cheap cures. Metal shutters, warped, stood ajar to a run of bricked-off arches that had not seen commuters in decades. Not emptiness though. The floor carried the scuffs of crates hauled and stacked. Patchy chalk sigils crusted the platform edge, lines drawn on the quick by someone who had drawn them before. A whiff of cardamom mixed with machine oil and damp iron. Behind a rusted grille, a painted sign read CAMDEN in a serif gone soft under the grime. "Ritualistic nonsense," Sharpe said from overhead. His accent clipped its way out of South London. "We pulled three knives from behind a crate. All kitchen, all pound shop. No ritual daggers, no goats. He slit himself, or someone helped." "He did not slit himself," Harlow said. She ran her gaze across the ballast. Footprints crisp in the damp grit where someone had stepped down. Two sets, men’s trainers, one wide, one narrow, and a smaller print so light it had not settled the stones at all. That one bothered her. She glanced to the rails. Dust lay on them like velvet. No wheel had shone these in years. On the base of the third rail sat a smear of something black-green. Grease, old, but touched by a hand today. The touch made a finger's crescent in it. Too much care for an amateur scene. "Look at his fingers," one of the techs said. "Under the nails." She lifted a hand, checked the nail beds. New skin torn into ragged half moons. He had grabbed something rough before he died. The right index nail bore a faint white line of chalk. She pressed her thumb to the knuckle. The joint gave under pressure. Dislocated post-mortem? That would take thought. The scene had been arranged with thought. "This market looked busy when it ran," Sharpe said. He hopped down beside her with a loose-jointed flop, trainers picking poor purchase on the ballast. "Council went in, boarded it eighteen months ago when the last squat fire took. We have vagrants. They love a stage. They put on a show for the tourists, nick a wallet, stick a knife in. One phone call to the Echo and you make a night of it." Harlow set the sheet back and straightened, face level with Sharpe’s shoulder. His tie sat half undone, the knot like a punched mouth. He stank faintly of stale coffee and mint. "Where is his wallet?" she said. "Still in his pocket. Cards and a sixty quid fold. That is the point, he does not look robbed, he looks like a man who wanted to be found like this." "Who phoned it in?" "Anonymous tip. Masked number, voice modded to sound like some YouTube prank. Said, and I quote, there is a tableau under Camden and you have ten minutes before the curtain drops." Harlow looked at the body again. The cut had bled. Not much. The pooled blood sat under him in a circle that stopped at the edge of a chalk line drawn around his torso. She crouched and touched the chalk with the back of a knuckle. Fine, fresh. It had sat on top of wet blood in places, not under. Whoever drew it had done so after he bled. Whoever drew it had not wanted to scrub the floor. "Where is the knife that made that cut?" she said. Sharpe lifted a shoulder. "On the floor behind the arch. Wiped, but we pulled prints. Probably his. We found one on a kebab box in his rucksack too. Name is Victor Latham, forty-five, freelance antiques dealer. Lives in Islington. Door was kicked for a welfare check two weeks ago, no answer. Neighbours say he travels." "He did travel," Harlow said. She looked beyond Sharpe to the dark line of an old turnstile. Its arms had been removed, replaced by a rope threaded with knucklebones, polished by hands. Each bone had been notched with five cuts. An entry counter. You took a bone and paid it back. This was not vagrant theatre. This was a doorway that wanted your tokens. She walked to the turnstile. On the floor by the base she saw a tiny object like a tooth. She crouched, lifted it with a gloved pinch. It was a coin of bone with a drilled hole and worn edges. She rolled it in her palm. Faint carvings cut into one side. A sigil like a bird's footprint. She did not like the way her skin felt under the glove when she touched it. An itch crawled along the hand that wore her watch. The old leather band creaked. "What is it now?" Sharpe said. "Another charm?" "Token," she said. "People pay to pass." "Pay with bones?" His laugh hit a note he did not control. "We have a cult and a ticket office." Harlow passed him the token. He made a face when he took it, then hid the face. "Bag it," she said. She moved to the stack of crates past the turnstile. The top bore chalk script, not written, scribed with a slow hand. The lid had been cracked and reclosed. She prised it up one nail-width and sniffed. Cinnamon. Old rope. Something like old pennies. Inside, cloth wrapped small objects that clinked as though they had teeth. She shut it with care. "Quinn." Sharpe gestured to the SOCO. The woman held up an evidence bag. Inside lay a small brass compass, case scabbed with verdigris. The face bore markings she recognised from the night DS Morris had gone through a doorway that had no hinges. Harlow took the bag. The needle trembled like a locked breath, then swung and held. It held not north. It pointed at the tiled wall where an advert for a patent digestive cure still grinned its rheumy grin. "Found under his thigh," the SOCO said. "Like he tucked it when he went down." "It is not a compass," Harlow said. "Course it is. A rubbish one," Sharpe said. "He was an antiques geezer. He hawked things in markets. He had a market in a station. We have all the threads we need." She lifted her left wrist. The leather of her watch band rasped. She set the compass bag close. The tick slowed. She pulled the bag back. It resumed. She brought it in again. The tick lagged like a heart under cold water. Sharpe watched with a face that tried for bored and landed at alert. "Magnet. Bit of iron in the wall. You can make the needle point at your mum with a big enough magnet." "You tried this in a classroom once," she said. "I am full of useful experiments." The compass needle flicked again. It moved wrong, like an animal that scented meat in a place it did not expect meat to be. Harlow held it while she angled her body to block the others’ sight. Her own eyes ran along the line of tiles at the far end of the platform. In one place, grout sat darker, not with damp, but with oil. A hand had rested there often, fingers brushing the same seams. "Who is your civilian?" Sharpe said. He was not looking at the wall. He was looking past Harlow's shoulder along the line of the platform. Boots clicked, soft, cautious. Harlow did not turn. "Museum liaison." "You brought a librarian to a stage set." "She will earn her keep." Eva Kowalski stepped down from the platform with a care that made the SOCOs unclench. Curly red hair piled into a knot had already started to escape. Round glasses fogged at the edges, then cleared. She tucked hair behind her left ear and adjusted the worn leather satchel strap across her chest. She took in the chalk on the ground, the crates, the token rope, the corpse with the neat cut. No flinch. Her green eyes were tired, but her gaze held. "Ms Kowalski," Harlow said. "Objects and marks. Short answers." "I assumed as much," Eva said. Her voice carried the soft edges of Oxford taught to cut when needed. "This is not theatre, Detective. This is a market. It moves. It sets a rule at the gate and a price behind it. That rope would be called a ledger if you were a poet and a turnstile if you were not. May I?" Harlow handed her the compass bag. Eva held it up to her face without touching the brass through the plastic. The needle trembled, corrected, rested in the same wrong direction. "Shade work," Eva said. "Protective etchings on the face. Trader’s hands. It points to places where the world wears thin. Someone paid good coin in a language that bites your mouth to make this." "Occult bingo," Sharpe said. "We all shout full house and go for chips." Eva did not even blink at him. "Your body does not match your cut," she said. "He was moved after the bleed, arranged for your photographer. Victor Latham did not stage himself." Sharpe squinted. "You know his name already?" "I read it off the bag on your table," she said. "I also read the cut. It follows the fifth rib too closely for a clumsy hand." Harlow let Sharpe and Eva talk and watched the platform. She had walked through this station with a torch once before when she still wore a uniform and her shoulders still fit her shirts tight. Back then, it smelled of mould and piss. Tonight the air held spice and the iron tang of money. Someone had thrown a party and left in a hurry. The chalk sigils along the edge repeated at neat intervals, spaced by the old pilaster capitals. The line near the body crossed a smudge of soot from a shoe that had been on the floor earlier. She traced that line with her torch and found a second sigil under the turnstile muster that had been wiped with water. It left a finger-drawn streak. Someone had kept one part of the floor clean while they dirtied the rest. "Show me his shoes," Harlow said. The SOCO held up a paper bag. She pulled out a pair of polished brogues, dark brown, soles thin with city miles but not ragged. Not a vagrant’s shoes. She bent the sole. Fine stones had worked in between the tread and the leather, but there was no dark scum of the ballast crushed to putty. He had not walked long on these stones. Sharpe sighed. "Someone brought him in. Or he came in and someone helped him lie down. Still fits my picture. Two blokes on spice get bold, stab a mark, panic, draw a few circles, ring us, leg it." Harlow turned the shoe and looked into the toe. A compacted lump of light grey powder sat in the tip. Chalk dust. She glanced to the cut edge of his shirt. The thread had nicked and rolled as it was cut by a blade that passed through paper at speed many times. Not a kitchen knife. Something smaller. Scalpel? Craft knife. The knives they had found would not produce a clean line like that, not with someone still moving. "Search behind the shuttered arch," Harlow said to the SOCO. "Find me paper with clean edges and blades that carry chalk dust. Bag any cloth with iron filings. Look for bone tokens. Count them. Make a note of any with five notches." The woman nodded and went. Sharpe folded his arms and stood too close. "You hear a tune, I can see it. Care to share the melody?" "They kept books," Harlow said. "Not the sort you like. Accounts written into ropes, entries made with finger bones. This is not a ritual murder. This is a message to others who trade here." "And the message says what?" "Do not bring a Met detective’s name to market." His laugh died when he saw her face. "You think he named you?" "He had my card once," she said. "Two months ago he came into the station with a box of brasses from a clear-out in Barnet. Said one piece ticked wrong. I never took the case. He left without the box. It went from my desk. He did not take it." Sharpe stared. "You lost a box." "It walked," she said. "Like other things in this city when they have teeth. Check his rucksack." The SOCO handed it over. Inside, neat compartments, a small ledger bound in cracked calf, a half-eaten apple that had not browned as much as it should. She sniffed it. It smelled of cloves. She set it aside and opened the ledger. Names. Times that looked like tides. Amounts with odd currency markings. Bone tokens drawn as circles with notches. One name had been pressed harder than the rest until the nib tore the page: MORRIS. Her fingers paused. The leather of her watch creaked again. She kept her face blank. She turned the page. At the back a loose rectangle of stiff card slid and dropped to the ballast. She bent and picked it up. A small white card, the size of a hotel key, embossed with a symbol like a wheeled eye. Written under it in a tidy hand: Veil Compass, one only, paid. Eva looked up when Harlow held the card out. "He bought the compass," Eva said. "He did not steal it." "The card calls it a Veil Compass," Sharpe said. "How poetic. You both love a title." "It will point to the nearest rift," Eva said. "To a door cut between places. It is not a toy. If it stopped your watch, Detective, you hold something awake." Harlow did not ask how Eva knew about her watch. Eva watched everyone who watched the door. "Door to where?" Sharpe said. He said it like he laughed at it and wanted the answer. "Another room in the same house," Eva said. "Only this one breathes on a different tide." Sharpe rubbed his jaw and looked to the tiled wall. "So our compass points to your magic door. Great. Is there a murderer on the other side?" "Possibly," Eva said. She did not apologise for the word. "Or someone who wanted to be found by the police tonight. Someone who required an audience. You said, ten minutes before the curtain drops. Does that sound like someone who planned for you to get bored?" Harlow walked to the tiled wall where the compass needle felt most eager. Her torch picked out a hairline crack in the grout that ran down and left like a thought stuck in a corner. The dirty patch where hands touched repeated under the same angle. Certain people had leaned in this place and pressed their ear. She set her palm flat to the tile. Cold. Under it, not a hum, not yet. The old station settled around them like a beast tucking its head under its wing. She clicked her tongue. "Sharpe, get uniform to seal the Camden Road entrances. Leave the back stairs by the service lift unmarked. People will prefer the back. No trampling, no heroics. Ms Kowalski, tell me what this mark wants to be." Eva stepped up beside her. She made no move to touch the wall. She stared, eyes flitting across the tile like a reader scanning a difficult script. "This is a gate that requires an object to complete a sentence. You have the object in your hand." Harlow looked down. The compass sat in the bag, needle twitching like a trapped thing. She lifted it until the needle squared to the crack. Her watch ticked, hesitated, and resumed at a different pace, a syncopation that set her teeth on edge. She felt it then, a thin vibration in her bones, the same she had felt three years ago in a drain tunnel with DS Morris at her shoulder, his laugh in her ear, his body leaving the way a breath leaves. She pushed the thought aside. She called it a thought and not a memory. She set the compass closer to the wall. "Quinn." Sharpe set his hand on her sleeve. "Do not touch the funny door with the funny needle. We have enough weird on the floor." "Stand back, DS," she said. "Authority noted," he said, but he did not let go. He looked smaller when he felt out of his depth and pretended he did not. The station answered for her. The tile under her palm warmed the way a coin warms in blood. A hairline crack parted like a mouth thinking about the first word of a confession. The chalk sigils along the platform edge ghosted pale in the gloom and then brightened, not with light, but with attention. The rope of bone tokens along the turnstile rattled against itself in a sound like teeth clicking. Sharpe’s hand left her sleeve. "Back two steps," Harlow said. "Yes, alright," he said. His trainers scraped. The crack widened. The compass needle hit the edge of the bag and kept trying to move. Her watch stopped. The last tick hung between one second and the next like a held breath. Something sighed behind the tiles. Air moved the wrong way and rustled the old adverts so that the men in bowler hats turned their heads as if they wanted to watch. The patent cure promised relief for biliousness and laudanum habits. Its painted lady’s eyes seemed to become almost kind. "Detective," Eva said. Her voice dropped an inch. "You stand in the answer to your first question. Do not step forward." Harlow looked at her. Eva’s hands were steady and open at her sides. Strain sat in her mouth, not fear. On the ballast by the corpse, blood started to creep, pulled not by gravity, but by interest, a slow thread inching toward the three tiles that had decided to become a threshold. "Whoever staged him wanted this open, now," Eva said. "Your anonymous caller wanted an audience. The market had a schedule. Someone moved it by force." "Move your people," Harlow said. "Already shouting," Sharpe said, eyes on the gap. A thin dark line split the wall from skirting to cornice. Heavier air pressed out, stale, faintly sweet, a smell like cloves and something that had been kept in a tin too long. The compass needle went still. It did not point. It aimed. The tile section toppled forward an inch and then stopped. Behind it, not brick. Not more tunnel. A black that was not darkness, but a material, velvety and hungry. It pushed a pressure into Harlow's sinuses that tried to make tears start. Her watch face fogged. The worn leather band dug. Voices rose behind her, sharps of alarm and a laugh from someone who could only laugh rather than gasp. The black lifted like a curtain. Something stood only just behind it, close enough that breath would have touched her face if they both breathed the same air. A shape like a man under a coat, but not a man's coat, a coat that hung with too many folds and no seams. Hands, if those were hands, cupped something small that glinted with brass. Harlow did not blink. "Step back from my threshold," the shape said. The voice did not come from the air. It arrived in her bones like a bass note. Beads of moisture formed on the tiled wall, not condensation, more like sweat. Sharpe swore, low and honest. Eva's green eyes narrowed as if she could make the form become clearer by force of will. The rope of bones rattled harder, then stilled, one token falling from its thread and landing at Harlow's boot. Beyond the split tile, other shapes moved, market shadows brushing past stalls that were not there and were. Feet stepped on a floor that did not match the platform. Something knocked a crate just beyond the threshold and a pile of small brass compasses slid and chimed like a handful of coins tossed on a tomb. The shape tilted its head, as if it could smell her badge through her coat. It lifted the small brass thing in its hands so she could see the face, etched with sigils that matched the one in her bag. "Step back or deal," it said. "And you do not have the right tokens."
