Quinn caught the constable’s wrist before he could lift the bone from the dead man’s mouth. “Photograph it first.” The constable froze, forceps poised above the corpse. A thin thread of saliva hung from the bone to the man’s lower lip. “Already done,” he said. “From inside his mouth?” He glanced at her and lowered the forceps. Quinn crouched beside the body. The man lay on his back across the platform edge, one arm bent beneath him, the other reaching towards the tracks. His collar had soaked up a dark pool of blood. A narrow wound showed beneath his jaw. A woman watched from the foot of the stairs. Her red curls had escaped their clip, and one lens of her round glasses had cracked. She held a worn leather satchel against her chest. Detective Sergeant Patel stood beside her, keeping a hand near her elbow. “Eva Kowalski,” he said. “She found him and called it in.” Eva tucked a curl behind her left ear. “I found him on the stairs. He was still breathing.” Quinn looked at the body again. His shoes pointed towards the tracks, his head towards the wall. “Who moved him?” “No one,” Patel said. Eva’s fingers tightened around the satchel strap. “He crawled.” “The distance from the stairs?” Quinn asked. “He got as far as the platform. I went for help.” “And left him alive?” “He told me to. He said there was someone behind the wall.” Patel took a notebook from his coat. “The entrance hatch was locked when the first officers arrived. Miss Kowalski opened it for them.” “With a key?” Quinn asked. “With a crowbar,” Eva said. “There wasn’t time to explain the lock.” Patel held up a sealed evidence bag. A short iron bar rested inside. “Her prints are on it. Blood as well.” “I used it on the hatch. Then I touched his neck.” Quinn rose. The abandoned station had no name on the walls. Someone had stripped the enamel signs, leaving pale rectangles among the soot-dark tiles. Old advertising frames lined the platform, their glass painted over from the inside. The air smelled of wet brick, bleach and the sharp mineral scent of fresh blood. A train passed somewhere beyond the tunnel wall. Its weight sent a tremor through the platform, though the rails in front of Quinn had rusted into their chairs. “Who is he?” she asked. “Leon Voss,” Patel said. “Forty-eight. Antiquities dealer. Two convictions for handling stolen property, both spent. His wallet and phone were in his coat.” Eva stared at the floor. “You knew him.” “He sold books. A colleague gave me his name.” “Which colleague?” “I’m not giving you someone else’s name until I know why Leon’s dead.” Patel opened his notebook. “You might start by telling us what you were doing down here.” “I came to collect a book.” “From a man carrying four thousand pounds in cash?” “Did you count it?” Patel’s mouth closed. Quinn held out her hand. Patel passed her the wallet in its evidence bag. Three banknotes sat in one compartment, a rail ticket in another. The licence showed Voss with a full beard and a smile that pushed his cheeks into his eyes. “No four thousand,” she said. “I wanted to see if she knew what he had.” Eva rubbed the bridge of her nose beneath her glasses. “You could have asked.” “And you could have answered.” Quinn handed back the wallet. “What book?” “A catalogue. Private collection, nineteenth century. I wanted to check an inscription.” “Where do you work?” “The British Museum archives.” Patel glanced at Quinn. “She has a staff pass. We’re checking it.” Eva shifted the satchel. Its flap hung open, revealing several worn spines and a fold of white cloth. “What’s in there?” Quinn asked. “Books.” “And the cloth?” Eva looked towards the body. “Something Leon was holding.” Patel reached for the satchel. Eva stepped back, and the constable by the corpse straightened. Quinn kept her voice level. “Put it on the floor, Miss Kowalski.” Eva lowered the bag between her shoes. Patel took out the cloth and unfolded it. A small brass compass lay inside. Green patina freckled its casing, and fine marks circled the glass. The needle pointed at the tiled wall behind Voss. Patel turned the compass in his palm. The needle swung until it pointed at the wall again. “That yours?” Quinn asked. “No. Leon pressed it into my hand. He told me to keep it away from the door.” “Which door?” Eva looked at the wall and said nothing. Quinn took the compass from Patel. The marks around its face resembled letters, though she could not place the alphabet. A scratch ran across the glass, deep enough to catch her thumbnail. “What does it point to?” “It finds openings.” “North’s an opening now?” “Not that sort.” Patel held out an evidence bag. Quinn slipped the compass inside, then passed it back. On the tiles near Voss’s feet, a bloody shoeprint pointed towards the stairs. A second print lay beyond it, faint at the heel and sharp at the toe. Both had the same square tread as Eva’s boots. Patel followed Quinn’s gaze. “Her left boot. The pattern matches.” “I told you I stepped in it,” Eva said. “You said you touched his neck.” “I did both. I knelt beside him.” Patel crouched at the first print. “The blood runs from the wound towards the platform edge. She stepped across it, then went upstairs. Voss followed her.” Quinn looked at the pool. Blood had run into the grooves between the tiles, but the flow stopped short of the platform edge. It had thickened around the man’s collar and beneath his cheek. “Where did he crawl from?” “The stairs.” “Show me.” Patel led her towards them. The steps rose to a landing beneath a steel service hatch. Mud marked the bottom two steps. Above them, dust lay across the stone in an almost even coat. A scrape cut through it where someone had dragged the crowbar after forcing the hatch. “There’s no blood,” Quinn said. “He could have held the wound.” “The cut’s under his jaw. He’d have left blood on his hand.” Patel looked back at the body. Both of Voss’s hands lay in view. One bore a smear across the knuckles. The other looked clean. “He wiped it off.” “On what?” Patel turned a page in his notebook. “His coat.” “His coat’s dark. Have the scene team check it.” Quinn returned to the prints. She crouched without touching them and followed the edges with her eyes. The first print contained a clear impression of a tiny stone lodged in the boot’s tread. The second had the same stone, but the blood around it had formed a small crescent. She looked at Eva’s boots. The left sole had blood along its outer edge. The right had none. “Take a step,” Quinn said. Patel frowned. “Not through the scene. On the dry tiles.” Eva obeyed. Her left foot rolled from heel to toe. The right landed ahead of it. Quinn pointed to the bloody impressions. “If she walked across the blood, where’s the right print?” “She stepped over it.” “With the same foot twice?” Patel studied the marks. He put one hand on the platform wall and bent closer. “The heel of the second print is blurred.” “Someone lifted the boot and set it down again. There’s no right print between them.” Eva’s face had lost its colour. “Someone used my boot?” “Not while you were wearing it,” Patel said. “You’d have noticed.” Quinn examined the sole again. A little lump of grey gum clung to the edge. “Did you leave your boots anywhere today?” Eva shook her head. “No. I came straight from work.” “Did you take them off here?” “No.” Patel glanced at the body. “Someone made a copy.” “That stone’s caught in the tread,” Quinn said. “A copy wouldn’t pick it up unless it was made after the stone got there.” Eva lowered herself onto the bottom step. “Leon asked to see my shoes.” Both detectives turned to her. “He said the floor was dangerous. He wanted to know if the soles were rubber.” “You handed him a boot?” Patel asked. “He looked at it. I lifted my foot.” “When?” “On the stairs, before he fell.” Quinn looked from Eva to the prints. “Which stairs?” Eva pointed to the tiled wall behind Voss. “There are stairs behind there.” Patel shut his notebook. “There’s brick behind those tiles. We checked the plans.” “Your plans don’t show this station,” Eva said. “I heard your constable say so.” “They show the tunnels around it.” “The station’s older.” Patel approached the wall and knocked. The tiles gave a dull, solid sound. He knocked again, moving along the row. At the fourth tile, the sound changed. He looked at Quinn. “There’s a cavity.” Eva rose from the step. “Don’t open it.” “You’ve been asking us to believe there’s a door.” “I said there were stairs. I didn’t say you should use them.” Quinn stepped past Voss’s body. Up close, the wall showed a seam in the grout, no wider than a knife cut. It ran from the floor to the height of her shoulder, then turned beneath an advertising frame. The frame held a blank sheet of paper. Quinn angled her torch across it. A shallow indentation marked the centre, shaped like a short, curved bar. She looked at the bone in Voss’s mouth. “Who put that there?” Eva pressed her lips together. “Miss Kowalski.” “It opens the door.” Patel gave a short laugh, then stopped when neither woman joined him. “Whose bone?” “I don’t know. You need a token to get in.” “Get into what?” “The Veil Market.” Quinn let the name sit between them. Patel had taken out his notebook again, but his pen remained above the page. “What do they sell?” Quinn asked. “Things that don’t belong in museums.” “You work in a museum.” “That’s how I know.” The constable called from the body. “Ma’am. There’s something under his tongue.” Quinn returned to Voss. The photographer had arrived and crouched at his head, taking close shots. Once she had finished, the constable used the forceps to lift the bone into a clear bag. He opened the dead man’s mouth wider. A scrap of paper lay against the back of Voss’s tongue. It had folded over itself and turned soft with saliva. Quinn watched the constable ease it out. There were numbers on one side. On the other, a single word in cramped black ink: MORRIS Patel saw it at the same instant. “Is that your Morris?” Quinn held out her hand. The constable placed the bag in her palm. Three years had passed since DS Morris disappeared from a locked interview room. The cameras had shown him entering with a witness. They had shown the witness leaving alone. By the time Quinn forced the door, the room had held an overturned chair, a broken cup and a smear of blood on the ceiling. The inquiry had taken her statement six times. It had not found Morris. She read the numbers again. Six digits, a slash, then another four. Patel leaned beside her. “File reference?” Quinn shook her head. She knew the Morris file reference. She had written it on enough forms. Eva stared at the paper. “Can I see that?” Patel moved the bag away from her. “You can explain why his name is in your dealer’s mouth.” “I can’t. Let me see the numbers.” Quinn held the bag where Eva could read it. “Those aren’t numbers,” Eva said. “Not all of them. The last mark is a letter.” “It’s a four,” Patel said. “Look at the top. It’s closed.” Quinn tipped the bag beneath her torch. The final character had a small loop. An A, written without a crossbar. Eva tucked her hair behind her ear again. “That’s a shelf mark. The first six digits identify a collection. The slash separates the volume.” “Which collection?” “I’d need the catalogue.” “The one Voss was bringing you?” “Yes.” Patel looked at Voss’s pockets. The scene team had removed the wallet and phone, but no book lay with them. “Search him,” Quinn said. The constable checked the coat, then the jacket beneath it. He found a receipt, a set of keys and a flat silver case containing two cigarettes. No catalogue. Eva pointed at Voss’s left cuff. “There. His sleeve.” A strip of dark cloth protruded beneath it. The constable eased it free. It was a ribbon bookmark, one end torn. A few fibres of cream paper clung to the tear. Patel turned towards the tiled wall. “Someone took the book through there.” “Or Voss never brought it,” Quinn said. “He had the bookmark.” “He had part of one. We still need the book.” Eva stood close enough to read the scrap again. “That shelf mark belongs to a restricted collection. I saw the prefix in the archives.” “You told us you needed the catalogue to identify it.” “I said I needed it to identify the volume. I recognise the collection.” “Whose?” Eva looked at the bone token in its bag. “Leon called it the Ferryman collection. He said the catalogue listed objects recovered from sealed rooms.” Quinn kept her eyes on Eva. “What sort of rooms?” “Rooms people couldn’t get out of.” Patel pulled a pair of gloves from his pocket. “We need to see what’s behind that wall.” Eva stepped between him and the advertising frame. “You don’t understand what’s down there.” “Then tell me.” “People who sell names. People who buy them. Leon dealt in records, and he was frightened enough to call me instead of his usual customers.” “What did he say on the phone?” “He said he’d found an entry under my archive’s shelf mark. He wouldn’t read it out.” “Why call you?” “I asked him to find anything connected with a sealed chamber. I’ve been researching them.” “For the museum?” Eva’s silence answered him. Patel moved her aside. The constable opened the evidence bag containing the bone. Quinn took it by the cleanest end and held it beneath the torch. Small notches ran along one edge. A faint red stain marked the other. She fitted it into the indentation in the paper. Nothing happened. “Turn it,” Eva said. Quinn turned the bone. A latch clicked behind the wall. The advertising frame swung towards her. Beyond it, narrow stone steps descended between brick walls. Red bulbs hung at intervals along a cable. Their light reached a landing below, where a curtain of linked brass discs covered an archway. Voices drifted through the discs. A man argued over a price. Something metallic struck a counter. Underneath came the smell of incense, old coins and meat cooked with too much garlic. Patel stared down the steps. “That isn’t on the plans.” “No,” Eva said. Quinn drew her warrant card from her coat and handed it to Patel. “Call for more officers. Tell them we’ve found an occupied space behind the platform wall. No one goes through without me.” Patel took the card but stayed where he stood. “You’re going in?” “Voss’s book is missing.” “And this woman knows the place.” Eva lifted her chin. “I’ve been twice.” “You said a colleague gave you his name.” “She did.” “Who?” “Aurora.” “Surname?” Eva’s fingers closed over the satchel strap. Quinn held out her hand for the compass. Patel retrieved the evidence bag from his pocket. The needle had shifted. It pointed down the stairs, towards the curtain. “Does it find the door?” Quinn asked. “It finds a rift. A passage between places.” “Where does that passage go?” “I don’t know.” “You’ve been twice.” “The Market moves. The passages change with it.” Patel looked from the compass to the stairs. “The Market moves?” “Every full moon. It’s under Camden now. It won’t stay here.” A shout rose from beyond the brass curtain. The discs rattled against one another, then fell still. Quinn passed the compass back. “Make that call.” Patel went towards the stairs to the hatch, phone in hand. The constable remained beside Voss, while the photographer packed her camera. Quinn took one step into the hidden passage. The stone beneath her shoe bore a dark streak. She crouched and touched it through her glove. Blood. Another mark showed on the next step, then a partial handprint on the wall. The fingers pointed upwards. Voss had climbed these stairs. The blood trail stopped at the threshold, where the bone token had opened the door. Beyond it, the platform tiles showed no marks until the pool beneath his head. Quinn returned to the body. “He didn’t crawl from the public stairs,” she said. “He came up from the Market.” Eva followed her gaze to the blood on the stone. “He was on those stairs when I found him.” “You said you found him on the stairs. You let us think you meant the other ones.” “I didn’t want the police down there.” “Who moved him?” “I did. He was blocking the door.” Patel came back from the hatch, his phone pressed to his ear. He had stopped speaking. “You moved him after he died?” Quinn asked. Eva shook her head. “He was alive. I pulled him through and went to the hatch. When I came back, he’d reached the platform.” “And the bone in his mouth?” “I didn’t put it there.” “Did anyone else come through the door?” “No.” Quinn looked at the body. The blood pool had soaked his collar, but the tiles between the hidden door and his head were clean. No drag marks, no drops. Someone had washed them. She sniffed near the wall. Bleach. Stronger there than anywhere else on the platform. “Where’s your coat, Miss Kowalski?” Eva touched the cardigan beneath her satchel strap. “I didn’t bring one.” Quinn looked at the constable. “Check her bag.” Eva caught the flap before he could reach it. “There are archive documents in there.” “Put it down.” Eva held on for another second, then lowered the satchel. The constable opened it. Beneath the books lay a folded grey coat. One sleeve had dried brown at the cuff. “Not mine,” Eva said. “Leon gave it to me.” Patel ended his call. “Why?” “He wrapped the catalogue in it.” “You said he didn’t bring the catalogue.” “I said he was supposed to give it to me. He changed his mind.” “Where is it?” “He took it back.” Quinn pointed to the bloody cuff. “Did you use that to clean the floor?” Eva’s eyes dropped to the tiles. “He told me to wipe the blood away.” “Why?” “He said they could follow it.” “Who?” A sharp crack came from behind the brass curtain. The voices in the Market cut off. The compass needle spun inside its bag. Patel dropped it onto the platform. The brass casing struck a tile, and the needle settled, pointing at Voss. The dead man’s fingers closed around the constable’s ankle. He fell backwards, striking his head on the rail. Quinn reached for him, but Voss pulled himself upright, blood spilling from beneath his jaw. His mouth opened. “Harlow,” he said, in Morris’s voice. The brass curtain burst apart behind them.
