The service gate yawned open on a breath of damp air and rust. Lights threw hard cones along the abandoned platform, bleaching the old posters and the algae spreading like bruises along the tiles. Blue tape snapped in the draught. Footsteps and murmurs bounced off brick and iron until they blurred into a wet hiss. Boots rang on steel behind her. You took your time. Harlow slipped under the tape and checked her watch out of habit. The leather strap creaked. Nine minutes past three. She looked past DS Patel to the body by the edge of the platform, one arm draped over the pit like he planned a swim and changed his mind halfway through. Power’s off to the branch, Patel waved at the dark rails. Urban explorer cooked himself where he shouldn’t. We’ll bag up the toys, give the warning to the press. Don’t trespass, don’t play trains. City loves a neat line. That what this looks like to you. Looks like fried idiot, yeah. Patel nudged a rucksack with his boot. Spray paint, pocket torch, stupid grin on his face that won’t be going anywhere. Harlow moved past him. The air tasted metallic, skin-prickling, ozone threaded with something like cloves that didn’t belong in a tunnel. The skin on the man’s hand ran smooth under the glove where the palm had blackened, but the scorch tracked along the lifeline in a tidy ribbon. The fingers had curled in, not out. His trainers hadn’t burst. The arcs at the fixings on the rail looked clean, no recent bite on the steel. She crouched and watched his chest. Still. No ghost of air to chase. Eye corners creased, fresh grit ground there, not from a tumble but from lying here a while. A turn of breath would have dragged it differently. Urban explorer with a manicure, Patel came to lean over. Look at those hands. No calluses. Rich boy got bored of Camden Lock. He didn’t touch the rail. We’ve got a scorch, we’ve got a corpse, makes itself. Harlow slid her fingers under the body at the waist and felt for a line on the tile. No drag. No scuff from the pit lip. A crisp square of dust shadow under the shoulder. He’d fallen from a short height and stopped. Fallen in place. You get any power readout from Control. They’re checking logs. It tripped around midnight. Patel lifted his chin toward the far tunnel. Could have been rats. Could have been this clown. Could’ve been the old place groaning. The old place groaned, right. Harlow checked the man’s mouth. Not the grey foam of an overdose. Tongue clear of bites. A thin line of soot under the upper lip, like someone had traced there with a finger. He went down with his mouth open. Yelling for help, Patel shrugged. Or trying to be dramatic. They film themselves in here. Harlow scanned the floor. Chalk dust smeared near the far wall, a scuff of white on the brick. At first glance, the usual graffiti spores, curse words, names. Up close, the marks curved with intent. Not a tag. A looped knot flanked by short bars. She’d seen that mark in a folder in her desk that she didn’t show anyone. She scraped a flake free and pressed it between her glove and thumb. The grit felt like bone ash. SOCO crouched nearby, the camera’s shutter tapped rhythm on the stale air. Harlow jerked her chin toward the chalk. I want lifts on those, both sides of the marks. And a cast. Of chalk, Ma’am. Of the pressure points. Someone pressed hard here. Not a sweep. And pick up the powder along the grout. Patel rolled his eyes at the wall. This one drew a circle. Maybe he worshipped the train gods. He didn’t draw that, she ran her thumb over the body’s cuffs. The frayed thread at the wrist sat under the scorch. He had his arms down when whatever this was hit him. SOCO worked in. Harlow edged along the platform lip, peered down for a sign of a drop, any disturbance in the grease that always clung to the pit. No ripple broken. The soot under his trainers hadn’t ground in. How did he get here then. Patel rocked back on his heels. Door there. He walked in, got stupid, tripped the juice, cooked, drop curtain. End of play. Harlow followed his nod to a service door halfway up the platform, metal wrinkled and painted the sick green the Tube loved for utility. The lock wore scratch marks, not recent. The dust on the threshold lay undisturbed except for two steps that came in and never left. The steps ended half a stride from the door, small soles, cheap rubber from a trainer you could buy on the market stalls. The rest of the floor held patchy prints, belonging to three or four pairs of boots that had stood around and moved away. Officers and SOCO. No light drag of a body. She went back to the rucksack. She didn’t like to dig through the dead’s belongings like a magpie, but needs. A battered camera; it powered on with a whine and showed one bar. The last photo framed darkness and a curved wall washed in the harsh blast of a torch. In the corner, half-caught, a small brass circle hung on a cord. Patel leaned in until his breath fogged the screen. He went shopping before he died. Harlow dug deeper. A small brass compass lay at the bottom of the bag, verdigris lacing the edge, face etched with things that weren’t north or south. The needle lay steady and wrong, pointing not toward the platform entrance but toward the far brick where the chalk sat. A drop of dried something marred the glass, brown-black. She turned the dial a fraction. The needle fought, twitched, then eased back to the same brick. What’s that. A pilgrim’s toy. She rested it in her palm and watched the needle insist. The weight felt familiar. The lines on the face meant nothing if you read them like maps, everything if you didn’t. Patel chuckled, sharp and quick. And here was me thinking you’d decorate the office with it. Get me a proper photo of the face. And gloves on whoever bags it. She tucked it into a clear pouch herself and sealed it, eyes still on the wall the needle loved. The man’s trousers had a ripped pocket. She slid fingers into the inner lining and found a lump. Her glove hit caught edges and smoothed curves. She drew out a sliver of bone carved into an oval, a hole drilled at the top as if for a cord. Teeth marks scored the surface. It had been in his mouth, or he had clenched it awhile. Fantastic, Patel muttered. He brought snacks. You know what this is. I know we’re under Camden, and kids sell little bones on strings in the craft market. Neat, right. You going to start confiscating dreamcatchers too. This one belonged to a door. A door to what. Harlow lifted her eyes to the wall. Tile patches had been hacked out years back, old maintenance. New scrapes kissed the brick, not horizontal like a crate had hit it but vertical, like something had swung in and scraped out. She passed her glove along the mortar lines, found a warmer seam, not from heat but from touch. Her fingertips prickled through the nitrile. She looked at the chalk again. Bars. Loop. Not an artist’s flourish. A map for those who knew. Give me your torch. Patel handed it over with a chuff. Shine away. She cut the beam low, raked it along the bottom row of bricks. Dust glittered in a band that grew less dense near a certain mortar course. A draft she couldn’t hear pulled at it, slanting it inward. She shifted the beam up. A smudge of verdigris streaked the edge of a brick at shoulder height, like brass had knocked there. She held up the pouch with the compass and matched the colour. Our boy didn’t bring a compass for the Tube, Patel pinched the bridge of his nose. You know what this is, Harlow. Some strange cosplay night gone wrong. They dressed up. They played wizards. He touched something hot. Game over. Next of kin get a lecture. Harlow sucked a breath through her teeth. The scorch in the man’s palm wasn’t the blurt of a rail bite. It followed a line like a wire, but no wire lay. The singe in his hair curled toward his crown in an ancient cowlick he hadn’t owned, pulled as if by wind. Ozone, cloves, the taste of metal after a lightning strike that never happened. Who found him. Track crew doing inspections, Patel dropped his hand. They come down Tuesdays. This leg’s quiet. They called it in and went back up. Didn’t touch him, they reckon. She looked toward the stairs to the service exit. Footprint powder gleamed there where SOCO had dusted, heavy boots in and out. No light trainers, no drip of panic sweat or vomit on the risers. Whoever came down and found him hadn’t been scared, or had stood further back and watched. That lock’s been off a while. Patrol were honest. But the call came from a burner, not from crews on the list. Check it. I’m on it. Another SOCO hurried over with a bag. Found this under the bench. Thought it might be the deceased’s, but no wallet with it. Harlow took the satchel in gloved hands. Worn leather. The weight said books. She opened the flap. Spines of old texts in French and Latin, a notebook with careful handwriting. A library slip from the British Museum tucked inside, the restricted archive embossed in small letters. Her eyes snagged on a scribble in the margin: "Veil—market—bone token—entrances move full." Patel peered over, voice rough around a laugh. He came down to revise. That’s new. He wasn’t alone. You’re guessing now. I’m reading. She closed the satchel and set it by the body. He had something not everyone gets. She lifted the bone oval. He had the key. He was at the door. He opened it, or he thought he did, she gestured to the chalk, the scuffed brick. And someone was there with him. You got a witness I should go shake awake. In here, she tapped her temple. Look at the left shoe. The edge melted a touch, a kiss, not a bite. He planted that foot nearer the wall. He turned his head when the heat came. The soot line under the lip says he breathed it. You ever see a rail arc give you a neat moustache. Patel squinted. He didn’t chew his lip, he’s not that tough. It wasn’t bravado. SOCO called from the far end. We’ve got fibres on the chalk, dark thread, not from the deceased’s hoodie. Slight lycra stretch. Harlow nodded. Bag them. And print everything within a metre of that wall inside and out. Dust the mortar line. Inside and out. She looked back at the seam where the dust sifted by an invisible thought. Inside. Patel folded his arms. Even if I sign off an occult rave, we’ve got no suspects. We’ve got a corpse with crap taste and a hairdryer finish. You want to add fairies to the incident report while you’re at it. Tick the box that says unknown mechanism. She pushed herself up. Never liked ticking boxes, Patel. Start with the list from the British Museum. Whoever borrowed those texts. You think our lad read Latin. He ran with someone who did. Maybe he carried the bag. She glanced at the small neat handwriting in the margin visible through the satchel gap, the type of hand that drew thought, not noise. Our boy liked being taken places. He had the compass. They had the map. He’s not your son, Harlow. I’m not knitting him a jumper. She touched the bone oval to the brick seam. It clicked with a sound lower than it should, something like the crack of a knuckle in prayer. Every head within three metres turned at once though they’d pretend later they hadn’t heard. Patel swore under his breath. That was— Brick. She pocketed the token in the evidence pouch, sealed it, and felt her heartbeat climb to match the watch’s quiet tick. Check the date for me. You forgetting your calendar now too. Humour me. Patel glanced at his phone. Two days after the full moon. He looked at the chalk again, then at her. This place moves. It shouldn’t be here. Ah. Harlow crouched by the man once more, stared at his face. Young, yes, but lines at the mouth said he’d practised a grin in mirrors, learned where to leave it. Clove on the air traced a memory down the back of her neck, heatless and sharp. She pressed her knuckles into the tile to ground it. DS Morris had tracked a whisper of chalk once, three years back, out by an old slaughterhouse. Harlow had laughed and called it goat bones and bored kids until a door had opened where there wasn’t one and swallowed what it wanted. She let the breath go and wouldn’t give that memory more room than it demanded. We’ve got two stories floated here, Patel. Yours prints easy. Mine smudges. She tugged the evidence bag with the compass, held it between them so the needle sat there like a tongue pointing at sin. But this doesn’t lie in the same way. The compass liked the wall like a dog that found a buried bone. Patel watched it and pretended he didn’t. You think you can find… what. The place. I think whoever did this didn’t leave by the stairs. And I think they were tidy. Too tidy. No panic scratches here, no stumble, only this neat game of hopscotch with chalk and brass. He had someone who knew the way. You’re going to catch me making a face again in the press shot if you keep on. I won’t make you famous. Promise. Harlow turned. The black mouth of the tunnel tugged at attention, not with movement but with that same downward draw of dust. The adverts for seaside holidays peeled back from the wall in a curl that made them look like gills. Above, Camden heaved on with night lorries and last buses. Down here, a market had breathed once. It might have sighed out. It might have forgotten to fully close its mouth. She clapped twice to cut through the murmur, got the heads up she needed. Expand the cordon by fifteen metres. No one touches the wall near the chalk without me. I want the British Museum on the phone. Ask for whoever signs out restricted texts in Ancient History, give them the accession slip number from the satchel. And find me records on burners used near Camden in the last six hours. Trace the tangle. People always think their strings don’t knot. Patel pointed toward the stairs as his phone already glowed. Press are sniffing at the gate. You going to give them a neat line. Tell them a man died under a city that’s older than their shoes. Tell them to go home. Or buy a thicker pair. You do poetry now, Harlow. Walk me a poet and I’ll bag them too. She pushed her palm to her watch and felt the warm circle of it. She checked the brick again. The seam hid in plain sight. The man might have smiled when it opened, if it had opened. Or he’d have swallowed the bone token like a prayer and never felt anything else. She stood, every line of her body aligning without thought, that old academy habit that never left. The platform numbers looked wrong from this angle, reversed and useless. She straightened them in her head anyway. You’re going to hate me for this. Always do. Bring a dog. Not a narcotics mutt. One that tracks human. I want to see where it thinks the scent goes. Where it goes into the wall. Let’s find out where it stops.
