The constable at the street entrance held out a bone token on his palm. “They took this off the dead man. The woman downstairs says we needed it to get in.” Detective Harlow Quinn took the token between finger and thumb. It was a thin disc, yellow at the edges, with a hole drilled through its centre. Someone had scratched a crescent into one face. “Did she say what it opened?” “She said it got us past the door.” Quinn looked at the stairwell behind him. Plywood covered the entrance to the disused Camden station, and a fresh police seal stretched across the boards. Two bolts lay on the pavement beside a cordless drill. “You got past without it.” “The boards weren’t there when the first car arrived.” “Who put them up?” The constable looked over his shoulder. “We’re asking.” Quinn slipped the token into an evidence bag. Beneath her coat, the worn leather strap of her watch caught on her cuff. She pulled it free and checked the time: 04:17. “Keep asking. Nobody touches the boards.” She descended through air that smelled of wet plaster and coal dust. A strip light buzzed above the ticket hall, though the station had been cut off from the grid eleven years earlier. Beyond the barriers, a woman sat on a plastic chair with a blanket around her shoulders. Red curls spilled across her round glasses as she bent over a leather satchel. Sergeant Patel stood beside her, holding a paper cup. “Detective. This is Eva Kowalski. She found him.” Eva raised her head. Freckles stood out against her pale skin. “I heard him first. I found him after that.” “What did you hear?” “A crash. Metal hitting tile.” Eva tucked a curl behind her left ear. “Then someone shouted.” “What did they shout?” “I couldn’t make out the words.” Patel handed her the cup. She gripped it without drinking. Quinn glanced at the satchel. Three books protruded from it, their pages crowded with paper slips. “Were you here for the books?” “I was here to buy one. A catalogue of protective inscriptions.” “At four in the morning?” “The seller kept his own hours.” Patel tipped his head towards the platform. “Come and see where he kept them.” The escalators had been stripped to their frames. Quinn followed Patel down a service staircase and emerged beside a platform lined with stalls. Velvet cloth covered trestle tables; glass jars held powders, teeth, and coils of dried vegetation. A rack of silver knives stood beside a crate of oranges. The fruit had begun to rot around the stems. At the far end, a man lay on his back beneath a poster for a film released twenty years ago. A forensic officer crouched beside him, sealing a swab. The dead man wore a dark suit and a waistcoat buttoned over his stomach. Blood had soaked the cloth beneath his left arm and spread into the grout. A narrow knife lay near his hand. Patel stopped outside the marked area. “Name’s Daniel Voss. Forty-eight. Passport in his inside pocket. Kowalski knew him as a bookseller.” “Cause?” “Stab wound under the arm, if the doctor agrees. The knife fits. There’s blood on the blade and his prints on the handle.” Quinn studied the body. Voss’s right hand rested palm-up, fingers curled. His left arm lay against his side, the sleeve creased where someone had bent it. Patel pointed to a stall opposite. “Kowalski says she was there when she heard the crash. By the time she reached him, he was on the floor. She called an ambulance.” “Where’s the phone?” “She used the one on the wall.” Quinn followed his gaze. A black telephone hung beside a tiled pillar. Its cord disappeared into a junction box with a cracked lid. “The line still works?” “The operator logged the call at 03:42. Kowalski gave the station name. Ambulance control sent us with the crew.” Quinn walked along the edge of the cordon. The tiles around Voss were dusty, except for a broad clean patch behind his shoulders. A scatter of pale grit lay over his shoes. “Who moved him?” Patel shook his head. “Paramedics checked for a pulse. They didn’t move him from that spot.” Quinn crouched. The clean patch had a straight edge, as though a heavy object had rested there for years. Four brass screws sat in the tile at its corners. One had been pulled loose and left in the dust. “What stood here?” Patel looked up at the poster. “A bench?” “Find it.” He sent a constable along the platform. Quinn leaned closer to Voss’s shoes. Both soles showed at their edges, coated in the same pale grit. The tops of the shoes were cleaner, apart from the scatter across the toes. “Did he walk through the dust and fall backwards?” she asked. “Looks that way.” “Then why’s it on his soles and not on his trousers?” Patel examined the trouser cuffs. Dark wool brushed the tile; no pale streaks marked it. “He brushed against something on his way down.” “Both feet?” Patel’s mouth tightened. “Or someone put it there.” Quinn pointed beyond the body. A thin white line crossed the platform from the clean patch towards the track. It broke where the paramedics had walked, then resumed beside a drainage grille. “Get a photograph before anyone else crosses it.” The forensic officer raised her camera. Quinn waited for the flash, then traced the line with her eyes. It ended at the lip of the platform, where a smear of white marked the edge. A constable returned. “Bench is behind the bookstall, ma’am. Turned on its side.” The bookstall stood five metres away, screened from the body by hanging rugs. Quinn walked around it. A wooden bench leaned against the wall, its iron feet chipped where the screws had held them. White grit clung to the underside. On the wall above it, a rectangular space showed through the grime. A framed print lay face down on the floor. Patel lifted the frame by its edge. The print showed the station in service, passengers in coats waiting beneath a clock. The glass had cracked across the clock face. “That’s your crash,” he said. “Could be.” The lower corner of the frame was wet. Quinn touched the tile beside it with a gloved finger. Water had gathered in a shallow groove and run towards the platform. “Where did this come from?” A pipe ran down the wall. Its valve had been turned shut, but water beaded around the joint. Beneath it stood an empty metal bucket. Patel peered into the bucket. “Cleaner heard the commotion, dropped the frame and ran?” “Then the bucket would have fallen too.” “Someone closed the valve.” Quinn looked at the wall behind the bench. A dark handprint marked the tile just above the floor. Four fingers pointed upwards; the thumb angled towards the pipe. “Photograph that as well.” Eva appeared at the end of the stall, escorted by the constable. “I told the sergeant about the leak.” Patel turned. “You told me the pipe was dripping.” “It was. The bucket was half full when I arrived.” “Who emptied it?” “I don’t know.” Quinn indicated the handprint. “Did you touch that wall?” Eva bent to look, keeping her hands inside the blanket. “No. Daniel’s stall was over there.” She pointed to a table piled with books. “He kept the catalogue under the counter. He didn’t leave it out with the others.” “Was he at the stall when you arrived?” “I saw his coat. He was wearing it.” “That wasn’t my question.” Eva pressed her lips together. “I saw him from the stairs. He stood by the table with his back to me. I called his name, but he didn’t answer. Then the lights went out.” “For how long?” “I counted to ten. I heard the crash at six.” Patel folded his arms. “You didn’t mention the lights before.” “You asked where I found him.” “I asked what happened.” “You asked whether I touched the knife.” Quinn turned back to the bench. Water had darkened one end of the wooden seat. The other remained dry, though dust covered both ends. “Did you see anyone else?” “Not on the platform.” Quinn looked at her. “Where, then?” “On the stairs. A man passed me on his way up. He wore a porter’s jacket.” “What colour?” “Blue. Brass buttons.” “Did he speak to you?” “He told me the market was closed.” Patel’s eyes moved to the rows of unattended stalls. “Convenient. A stranger nobody else saw.” “There were people here when I arrived,” Eva answered. “I passed three at the ticket barriers.” “Names?” “I didn’t ask.” Quinn left them at the bench and returned to the body. The forensic officer had opened Voss’s coat. His shirt beneath the waistcoat was white, except for the blood at his side. A thin brass chain crossed his chest and vanished into a pocket. “What’s on the chain?” Quinn asked. The officer drew out a small compass with a gloved hand. Verdigris mottled its brass casing, and tiny symbols circled the face. The needle pointed towards the far wall. “Don’t open it,” Eva called. Patel stepped aside as she approached. “It’s a compass,” he said. “I can see that.” Quinn took a closer look at the symbols. Their lines had been cut into the metal, not painted. “What does it show?” “Not north.” Patel held out his hand. “Then you can explain it at the station.” Eva kept her eyes on the compass. “It points to a rift. An opening between places.” Patel gave a short laugh. Quinn watched the needle. As the officer turned the casing, the needle swung and settled towards the same patch of wall. “Put it on the tile,” Quinn said. The officer placed it beside the body. The needle held its position. Quinn crossed to the wall. Damp streaked the tiles beneath an advertising frame. A service door stood to the left, its padlock coated with rust. To the right, a section of tile looked newer than the rest, though dirt had settled into the grout. Patel rattled the padlock. “Solid.” Quinn studied the newer section. The bottom row sat a fraction proud of the floor. A narrow scrape ran across the tile in front of it, interrupted by the white line of grit. She knelt and pressed her fingers against the grout. The lower edge shifted. “Get me a light.” Patel handed over his torch. Quinn shone it into the gap beneath the tiles. A strip of rubber showed behind them, compressed against the floor. “Not a repair,” she said. “A door.” Patel crouched beside her. He found a recessed catch near the advertising frame and pulled it. The tiled panel swung inwards on hidden hinges, dragging a short arc through the dust. Beyond it lay a narrow room with shelves built into the walls. A single lamp burned over a table. The air carried the metallic smell of blood. Patel stepped through first. Quinn followed, careful of the floor. A pool had dried beneath the table, and a second knife lay in it. Its handle was clean black wood; its blade had disappeared beneath a folded cloth. On the table stood a metal bucket, filled to the rim with pink water. A wet cloth hung over its side. Patel stared at it. “The bucket from the platform.” “Another one. Eva’s was empty.” Quinn pointed to a pair of parallel marks in the blood. They crossed the floor towards the door, spaced the width of a man’s shoulders. At the threshold, the marks vanished beneath pale grit. Patel looked back towards Voss. “They dragged him out.” “And put a different knife beside him.” The sergeant moved towards the table. Quinn held out an arm. “Stop. Look at the floor.” A shoeprint marked the blood beside the bucket. Its heel had a square notch missing from the outer edge. Another print, fainter, led towards a shelf at the back. Patel lifted his torch. “There’s something under the shelf.” Quinn followed the beam. A folded blue jacket lay wedged against the wall. One brass button had come loose and rested in the blood beside the notched heel mark. From the platform, Eva’s voice reached them. “That was his jacket.” Quinn turned. “Whose?” “Daniel’s porter. The man on the stairs.” Patel looked from the jacket to the body outside. “You knew him?” Eva gripped the strap of her satchel. “I knew his face. Daniel called him Morris.” Quinn’s hand closed around the doorframe. “Did he give you a first name?” “No.” “Did he have a mark on his face?” Eva frowned. “A scar. Here.” She touched the skin below her right ear. Quinn took a photograph from her wallet and held it out. The paper had softened at the folds. Eva leaned into the light. “That’s him,” she said. “That’s the man I passed on the stairs.”
