The stairs ended at a tiled archway and a man with a bone token on a cord around his neck. He looked Harlow Quinn up and down, taking in her dark coat, the gloves, the badge she hadn’t bothered to hide. Behind him, the abandoned station breathed dust and damp. Beyond that, beyond the line of old iron gates, the Veil Market glimmered in the disused ticket hall: strings of yellow bulbs, canvas awnings, tables crowded with bottles and silverware and objects she had no intention of identifying. “Police,” said Detective Sergeant Mercer. The doorman’s eyes stayed on Harlow. “You’re late.” “Dead man’s been waiting,” Mercer said. The man looked at the bone token in Mercer’s palm, then stepped aside. Harlow crossed the threshold. The token was warm where Mercer had been holding it. She disliked that. She disliked the station, too, with its blind tunnels and tiled pillars, its signs pointing to platforms where no train had run in decades. Most of all, she disliked the fact that a market full of people had been trading here for hours without anyone in Camden noticing. It was the full moon. The market had moved to the station beneath Camden tonight, apparently, though no one had yet explained how a market moved or why the moon mattered. A source had led them to the entrance. A warrant had led them down the stairs. The bone token had got them through the gate. Harlow adjusted the cuff of her coat. Her worn leather watch sat snug against her left wrist. “Show me.” Mercer led her through the market. The sellers had pulled their stalls back from the east platform, leaving a wide channel between the last row of tables and a strip of yellowed tiles. A few customers lingered under the lights. They watched Harlow pass without curiosity. That was worse than curiosity. She knew the look of people who had agreed, all at once, not to notice something. At the platform edge, a uniformed constable lifted the tape for her. The body lay on its back beneath a dead station clock. A narrow knife stood in the centre of his chest, its black handle upright as a finger pointing at the ceiling. Blood spread beneath him in a dark, glossy pool. His coat was good wool, once grey. His shoes were polished. He had a narrow face and a silver ring on one hand. “Name?” Harlow asked. “Not confirmed,” Mercer said. “One of the market traders called him Dallow. Mid-forties, maybe. The stallholders say he was dealing information. No one saw the attack.” “Of course they didn’t.” Mercer crouched just outside the blood. He was careful not to cross the tape, a small courtesy to the scene. “One wound, straight in. Looks like a quick job. Someone knew what they were doing. We found prints leading from the stairwell. One set, size ten or eleven. They stop at the body.” “And?” “And no prints going back. Either the killer doubled up along the track or went through one of the service tunnels.” Harlow looked past him. The old platform ran into darkness at both ends. The rails had been removed, leaving a trough of black gravel and rust. The tunnels were bricked over. “Those tunnels are sealed.” “On the plans, yes.” “Have you checked?” “Not yet. I’ve got two officers on it.” “Then you don’t know.” Mercer stood. He had the solid, unhurried manner of a man who preferred evidence that behaved itself. “The market’s full of people with reason to keep quiet. He was stabbed during a deal. The killer walked in, did it, walked out through a tunnel. That’s the cleanest explanation.” “Cleanest isn’t the same as right.” She moved closer to the body. His face was slack, lips parted a little. A thread of white had settled at the corner of his mouth. Harlow leaned in. No smell of fresh fear, no sweat, no urine. The knife’s handle was clean. Too clean. The man’s left hand lay open beside the pool, fingertips purple at the tips. “Has anyone touched him?” “SOCO checked the outer clothing. They haven’t moved the knife.” “Good.” Harlow crouched. The station’s dust lay thick on the tiles beyond the tape, grey as old flour. It clung to the grout, gathered at the bases of the pillars. It covered the dead clock’s casing. But the body had none on him. Not on his polished shoes. Not on the folded crease of his trousers. Not even at the hem of his coat, where dust ought to have caught. Mercer followed her gaze. “He was brought in clean.” “Maybe.” “Or he stood on a sheet.” “Maybe.” She leaned over the blood pool without crossing the tape. It had spread in a smooth oval, no splashes on the nearby tiles, no drops leading away. A small bead clung to the knife’s guard. The wound itself was dark and dry around the blade. “Any blood on the stairs?” she asked. “Just the prints.” “Then where did this come from?” Mercer’s mouth tightened. “SOCO will tell us.” “SOCO will tell us what they can prove.” She eased lower, careful not to put her knee on the floor. The man’s shirt had been cut open around the knife. The edges of the fabric were stiff, but not soaked. The pool looked too large for the wound. She could almost hear DS Morris asking what had been spilled, not what had been stabbed. The thought arrived without permission, sharp as a needle. Harlow pushed it away. “Get the pathologist down here,” she said. “And photograph the palms before they take prints.” Mercer glanced at the body’s hands. “You think he was moved?” “I think nobody’s earned the right to say he wasn’t.” She stood, then walked the edge of the scene. One set of footprints had crossed the dust from the platform stairs. The tread was clear, square-heeled, with a crescent cut into the left sole. Each print led toward the body. No drag marks. No second set. No scuffs at the pool. She followed the prints backward. They ended at the edge of the old platform, then picked up again three feet away, as if whoever had made them had stepped across an invisible gap. “Mercer.” He came to her side. “Look at the dust.” “I am.” “No. Look at the heel.” The marks were deep at the toe and shallow at the heel, all of them. The prints had been laid carefully on the powder, but the dust beneath each toe had not been pushed forward. Whoever made them had not walked into the station. The impression was backward. A print made by a foot moving away, heel first, then toe. Someone had walked the marks in reverse. Mercer frowned. “Could’ve been a trick.” “It is a trick.” “You think the killer walked backward from the body to the stairs?” “No.” Harlow looked down the line. “I think they wanted us to think someone came in that way.” Mercer glanced at the corpse. “Why?” “To make us look for an ordinary entrance.” “That is an ordinary entrance.” “Then why are there no prints from it?” The market hummed behind them. A woman in a green veil laughed at something a vendor said. Somewhere, glass chimed against glass. Harlow turned her attention to the tiled wall behind the body. Its surface was dull with age, but a rectangle of it caught the station light differently, smoother than the surrounding tiles. It ran from floor to shoulder height, a patch of old repairs too neat to be old. At its base, a thin grey line marked the floor, unbroken by dust. Mercer followed her stare. “Service access?” “Could be.” “I’ll get the plans.” “Get me someone who knows where the plans lie.” She returned to the body. In its right hand, tucked against the palm, lay a small brass compass. The casing was green with verdigris, and its face was etched with a pattern of tight, hooked marks. Harlow reached for it with gloved fingers. The needle swung once, trembling, then settled. It pointed at the tiled wall. She turned the compass around. The needle shivered and swung back toward the wall. “Magnet,” Mercer said. “Maybe.” “Or a piece of market rubbish.” “Maybe.” He said it as if he had won something. Harlow lifted the compass closer to the wall. The needle pressed to the glass, unwavering. She turned her body until she stood between it and the tiles. The needle did not shift. “Get a picture,” she said. Mercer called over the SOCO photographer. Harlow kept the compass level. She could feel a faint vibration through her glove, though the station was silent around them. The needle quivered, not from movement, but as if something on the other side of the tile had tugged at it. The old station clock above them had stopped at 3:17. Harlow glanced at her watch. A little after midnight. The face had been dead for years, the hands fixed in their useless certainty. She thought of Morris for the second time, and this time the thought stayed. Three years ago, he’d vanished in a locked room with the key in his pocket. They had found no blood, no forced entry, no usable explanation. Harlow had signed the report. She still remembered the look on the superintendent’s face when she asked whether he believed his own conclusion. Mercer touched her shoulder. “You all right?” She pulled away. “Don’t.” He lowered his hand. “You’re seeing something.” “I’m looking.” “Same thing, sometimes.” Harlow returned to the body. The purple at the man’s fingertips deepened into the pale skin. There was more colour along his cheek and forehead, a bruised wash pressed to the front of him. She leaned in. The body lay supine, but the discoloration didn’t. Blood had settled there while he’d been face down. For hours, perhaps. The skin was fixed, not a transient flush. She tapped the edge of the pool with a gloved finger. The blood held a wet shine. There was no dust on it. “Dead before he got here,” she said. Mercer stared at the body. “He was stabbed here.” “The wound may have been made here. He wasn’t alive when it happened.” “You can’t know that.” “The blood didn’t come out of him.” “Could’ve been cleaned.” “Then why leave a pool?” Mercer had no answer. Harlow stood and looked again at the wall. The seam at its base ran straight across the tiles, too narrow to be a door. There was no hinge, no handle, no scuff of a panel being pulled aside. The dust in front of it had settled in a shallow crescent, as if the air had blown outward from a crack and then gone still. On the tiles, just above the seam, the dust was thinner than anywhere else. The prints had been laid to lead away from the body. The blood had been poured to make a killing. The knife had been planted after death. All of it pointed toward the stairs, toward the surface, toward a world in which a man came in, stabbed someone, and left by a route everyone could search. But the body had not come down the stairs. It had arrived from the wall. She looked at the compass again. Its needle stayed fixed. “Mercer,” she said, “the killer didn’t need a tunnel.” He followed her gaze. “What did they use?” Harlow did not answer. She moved close to the tiles and held the brass compass before the seam. The needle pressed hard toward the wall. For an instant, the smooth rectangle of tile seemed to deepen, its surface going dark as a reflection in water. Then the station lights flickered, and the wall was only a wall. Mercer swore under his breath. Harlow kept her hand steady. She had no name for what she’d seen. She had the body, the false trail, the staged wound, and a compass that pointed into brick. It was not enough to prove anything. It was enough to know where the next question lay.
