The stairs from the street came down in three flights, and by the second one Harlow Quinn could smell it — wet lime, iron, and the cold mineral breath of a place that had not been opened in years. A constable at the cordon ducked under the tape without being asked and handed her a pair of nitrile gloves, then a bone token the colour of old ivory, drilled through and threaded on a length of twine. "Found it in the dead man's coat, ma'am. DS-er — Inspector Hale says you'll want it." She looped it over her wrist, below the worn leather watch, and stepped onto the platform of the abandoned station beneath Camden. Forensic lighting had turned the disused southbound stop into a theatre of white glare and hard shadow. The rails were long since lifted; where they had been there was only ballast and standing water, black and still. The stalls of the Veil Market were gone — three nights from the full moon, and the traders packed up and moved the way they always did, leaving nothing but chalk, a scatter of bent nails, and the ghost of a striped awning's shadow on the tiled wall. Someone had swept. Someone always swept, and then the dust settled again, and the floor had taken on the fine grey bloom of a chalkboard waiting to be written on. And across that floor ran a single set of footprints. Eva Kowalski stood just beyond the chalk line, her satchel slung across her body as if the restricted archives of the British Museum might close up and expire without her. Her round glasses had steamed from the temperature change and she was polishing them on the hem of her jumper, a habit that Quinn had watched her perform perhaps four hundred times. She tucked her curly red hair behind her left ear and put the glasses back on. "You took your time," she said. "I was asleep. You rang me at five past four." "I rang you first. You told me to ring you first and then nine-nine-nine." Eva's freckled nose wrinkled. "I did the nine-nine-nine. They took forty minutes to find the service door. You took twenty-six." Quinn crouched at the tape and looked. The man lay on his back in the centre of a chalk circle, arms at his sides, coat buttoned to the throat. Fifties, maybe sixties; thinning hair; the calloused hands of someone who counted things for a living. Lividity had already fixed purple along his jaw and the backs of his hands. A single dark wound showed beneath the left ribs, the shirt stiff and black with it. "That's Silas Wren," Eva said. "He traded in the Market. Names, addresses, routes — who was carrying what, and through which door. Half of Camden vice could tell you his price list." "And the circle?" "Ritual." Eva said it with the particular care of a woman who had spent a master's degree learning not to use the word. "The sigils are protective — binding. It's a summoning circle, Harlow. He was drawn into the centre and—" She stopped, tucking hair behind her ear again. "It's the third this year. Different boroughs. Always within a fortnight of the moon." Quinn did not answer. She was looking at the footprints. They came from the north staircase — the stairs she had just descended — and they went straight across the platform to where the body lay. One set. Unhurried, even stride, a little over seventy centimetres. They came down the stairs, crossed the floor, and stopped at the chalk line. And there they ended. "There's only his," Quinn said. "Only his what?" "Prints. These are his." She nodded at the dead man's shoes, scuffed brown brogues, thin soles. "Same tread, same step, right down to the drag of the left toe where he favouring it. He walked down here alone." She let that sit. "So where did the killer walk?" Eva looked at the unblemished grey dust beyond the circle. "He didn't walk. That's rather the point." "You don't think it's possible he was already inside? Waiting in the dark when Wren came down?" "It's possible. It's also possible he opened a door that isn't there. Harlow — there are things about this building you haven't been briefed on. Things about the Market." "I've been briefed on the Market. It sells things that shouldn't be sold, it takes a bone to get in, and it moves house every full moon." Quinn stood. Her knees protested; she ignored them. "What I haven't been briefed on is how a man is ritually sacrificed in the middle of a circle that nobody was ever inside." Eva blinked. "What?" Quinn stepped over the tape, walked to the edge of the chalk circle, and crouched again, careful of the prints. She took out her torch and laid the beam almost flat across the floor. The circle was unbroken. Not a scuff, not a smear, not the faintest grey drag where a shoe had crossed it. But the victim's footprints ran right over the chalk, three, four, five steps, and crossed the line itself — and where they crossed, the chalk was untouched, lying in its crisp ridge on top of his own print, undisturbed. "The circle was drawn after he was dead," Quinn said. "After he walked into it. Someone knelt down with a stick of chalk and worked around the body, and then drew straight over his footprints." She let the torch beam rest on the neat white line lying across the brown print of his right shoe. "Nobody stepped into this circle, Eva, because nobody needed to. He put himself in the middle and then somebody else decorated him." Eva came and stood at her shoulder. She was shorter by half a foot and had to lean to see. Her breath went out of her slowly. "That's not—" She pushed her glasses up. "A ritualist wouldn't— the working has to be consecrated in sequence, the ward, then the— you can't just draw over—" She stopped. Tucked hair behind her ear. Looked at the sigils for a long moment with the expression of a person re-reading a sentence and finding the verb wrong. "These are backwards," she said quietly. "Say that plainer." "The inner sigils. They're mirrored. In any real tradition the protective marks are drawn facing inward, toward the working — you'd read them standing in the centre of the circle. These read correctly if you're standing outside, looking in. They're a copy of a copy. Somebody traced them through glass, or from a photograph, or from a page turned the wrong way." She looked at Quinn. "Whoever drew this has never performed a ritual in their life." "Then what is it?" Eva was quiet for a moment. "It's a costume," she said. "Someone wanted a body found in a circle, and found it quickly, and found it with the right kind of people reading it. The Market's regulars, the moon, the word sacrifice in a detective's mouth." She pushed her glasses up again. "We were meant to see this, Harlow. That's all it was built for." Quinn straightened up. The wound under Wren's ribs nagged at her — a single clean puncture, hardly any blood for it, the shirt soaked in a patch no bigger than a hand. He had not bled like a man struck where he lay. He had bled somewhere else, or bled into something, or bled before he was put down gently with his coat buttoned and his arms arranged at his sides like a shop window. She took the compass from the exhibit bag when the Scene of Crime officer brought it over. Small brass, casing filmed with verdigris, face etched around its rim with sigils far more intricate than the chalk forgery on the floor — the work of a Shade artisan, Eva had told her once, when Quinn had first seen one in an evidence tray and asked why the needle was pointing at the wall. It was pointing at the wall now. Not north. Not magnetic north. The needle stood at an angle to the platform, steady as a plumb line, aimed at a patch of cream tiling beneath the station's ghost-sign — the words half scrubbed away, a destination that trains had stopped serving in 1968. "That's Wren's?" Quinn asked. "He sold two of them last year. That one's his own." Eva peered at the needle. "It points at the nearest rift. It's been swinging since they brought it up." Quinn walked to the wall. Up close the tiles showed it: a rectangle roughly the height and width of a man, the grout a shade paler than its neighbours, the edges not quite true. She put her gloved hand flat against it and felt, very faintly, a current of air — warm, organic, moving. Like breath. She got her fingernails under the top edge of one tile and pulled. It came away with a soft grating sound, and behind it was not brick and not pipe but a dark vertical gap, and the warm breath of it touched her face, and the compass in her other hand jumped — the needle whipping round twice and settling, pointing into the hole as if it had found a home. "There," she said. "Here's your door." Eva came to stand beside her and looked into the void. "That shouldn't be open. That shaft was sealed before I was born." "Then someone unsealed it recently, because the mortar's dust in the frame and not on the ledge." Quinn shone her torch in. The beam fell away into a drop, and on the near lip of the opening, scraped bright across the iron lip, was a smear of something dark that had not been there long enough to dull. "Wren bled down there, not here. He was carried up and arranged on the floor — coat buttoned, arms at his sides — and then somebody chalked a circle around him and walked out through this hole without leaving a single mark on a floor you could print a coin on." She set the tile back and turned. "The prints are his, so he came willingly. The circle is fake, so the killer isn't one of the Market's people — or if he is, he's been reading rather than practising. Nobody left by the stairs. Nobody left by the floor." She looked at the chalk, at the neat white lie of it. "Which means the man who killed Silas Wren knew this station better than the people who work here. Knew about the void behind the wall. Knew what a detective would want to find when she came down at five in the morning." "And what's that?" Eva asked. "A story." Quinn checked her watch out of habit — half past five, the leather strap soft and dark with eighteen years of use. "We're supposed to take this upstairs and say the clique did it, and open a file with 'ritual' in the first line, and start watching the Market's regulars until one of them breaks." She looked at the body in its unbroken circle, and at the single line of footprints that came down the stairs and never went back up. "Ask your archives for anyone who's been inquiring after the station's original 1906 survey plans. Someone's been doing his homework, and he's left us a costume to wear while he does it." Eva did not tuck her hair behind her ear this time. She was looking at the wall. "It's still warm," she said. Quinn looked at the compass in her hand. The needle had not moved. It pointed into the dark behind the tiles with the patient, unwavering certainty of a thing that had been made to find exactly this, and would not be argued with, and would not be still.
