The platform smelled of wet brick and something older underneath, like coins kept too long in a pocket. Harlow Quinn stood at the bottom of the stairs with her hands in her coat and let the place settle around her before she moved. Camden Town station had closed to passengers in 1992. The tiles still carried the ghost of a tube map, faded to the color of weak tea, and the advertisements on the far wall had peeled into strips that hung like old bandages. "Ma'am." Detective Inspector Tom Pardoe came down the platform toward her, collar up, a torch in one hand. He had the look of a man who had already decided what he was going to say and wanted to say it before anyone argued. "White male, mid-forties. Found by a council inspector at half five. We think he came in through the old ventilation shaft off Hawley Street." "We think?" "Gate's rusted shut. Someone's been cutting through the mesh, but not recently, if you ask me." He shone the torch down the platform. "Looks like he got high, wandered in, and took a bad fall from the edge. There's a drop onto the rails. Probably caught his head on the lip of the platform on the way down." Quinn walked toward the body without answering. The man lay on his back on the concrete, arms loose at his sides, eyes open. His coat was dry. The tunnel behind him dripped steadily from a dozen cracks in the ceiling, and the floor for ten metres in every direction was slick with condensation, yet his shoes, a pair of good brown brogues, had no water on them at all. She crouched beside him. No blood on the concrete beneath his head. No mark on his scalp when she tilted it gently with a gloved hand. No smell of alcohol, no powder residue at the nostrils, no needle marks she could find. "Fall," Pardoe said behind her. "Concussion. Happens." "Does it?" Quinn studied the man's left hand. It was curled, and when she eased the fingers open, a small, pale object rolled into her palm. Bone, polished smooth and carved with a thin spiral. A token. She had seen one before, in an evidence locker three years ago, and had spent four months trying to forget the tag number attached to it. She set it on the concrete and did not look at Pardoe. Instead she looked at the wrist. His watch had stopped at eleven twelve. The face was cracked, the second hand frozen mid-sweep. But his phone, in the inside pocket of his coat, read 2:41 when she woke the screen, and she did not need a forensics team to tell her that a man who fell at eleven twelve did not lie on a dry coat for three hours in a flooded tunnel. "Someone set that watch," she said. "Or someone wanted us to think they did." "Or the damp got in it." "Pardoe, look at the floor." He did, with the reluctant patience of a man who had been waiting for her to finish. Quinn pointed with her pen to the far end of the platform, where the tiles gleamed under the torchlight. Faint prints ran across the wet surface, long and narrow, the heels deep and the toes barely marked. They came from the stairwell and walked straight toward the far wall, where a tiled panel bore an old ad for a brand of tea that had been out of business since the seventies. They stopped at the wall. There was nothing beyond it but more wall. "Could be the man himself," Pardoe said. "Wandering." "Then he walked into a solid surface and kept walking?" She stood, knees cracking, and moved to the wall. The tiles there were clean. Too clean, in a place where grime had gathered on everything else for thirty years. She ran her fingers along the grout. It was newer than the rest, pale and smooth, as if someone had repaired a seam recently and very carefully. The compass was lying in the dust by the man's boot. She had not noticed it until her eyes passed over the spot a second time. Small, brass, its casing gone green at the edges with verdigris. She crouched and lifted it with two fingers. Its face was etched around the rim with sigils, tight and precise, and she knew at least three of them. They had been in the margins of DS Morris's last notebook, the one she had been given in a plastic bag with his effects, the one she had read every night for a year and still could not explain. The needle was not resting. It turned slowly, trembling, and then swung with a small, decisive click until it pointed at the clean tiles of the far wall. "Ma'am?" Pardoe said. "What's that?" "A compass." Her voice came out level, which pleased her. "It's pointing at something." "At the wall." "At whatever's behind the wall." He laughed, not unkindly. "You can't seriously think there's a room behind it." Quinn did not answer. She was looking at the wet prints again, at the way the heels pressed deep into the tile, the way they stopped dead at the seam in the grout, and she was thinking about the bone token in its evidence bag, and about a man whose watch had stopped at the exact minute someone had decided he should die. Morris had found a seam like this, once, in a building in Holborn. He had described it to her in the car, laughing at himself, and then he had gone back alone and never come out. She slid the compass into her coat pocket, where it sat warm against her ribs, its needle still straining toward the wall. "Get a team to take the grout samples," she said. "Tell them to be careful with the tiles. And Pardoe?" "Ma'am?" "Don't let anyone touch that token but me."
