The Northern line platform at Camden had been sealed for nearly a decade, and the damp had long since claimed the advertising tiles. Harlow Quinn stepped down from the last of the iron stairs and felt the cold rise through the soles of her shoes. The air smelled of wet brick and something sweeter underneath, like lilies left too long in a vase. "Mind the third step, ma'am. It's given way." DC Rhys Fenwick stood at the bottom with a torch angled at the floor, his breath clouding in front of him. He was twenty-nine, eager, and had the habit of tapping his pen against his notebook when he was nervous. The pen was going now. "Third step," Quinn said, and stepped over it. The body lay near the platform's edge, face up, one arm flung toward the tracks as if reaching for a train that had left a century ago. The man wore a charcoal suit that had cost more than her monthly rent. His shoes were polished. His hair was dry. That was the first thing that snagged. Quinn crouched beside him, knees cracking, and looked at the stone beneath his shoulders. The floor was slick with condensation, a fine film of moisture beading on every surface, yet the fabric of his collar was bone dry and the back of his jacket had left no pale stain on the grime. "Time of death?" she asked. "Pathologist's guessing sometime between midnight and three." Fenwick shifted his weight. "Lividity's fixed on his back, so he's not been moved after he went down. Which is what I'm saying. He came down those stairs, lost his footing, cracked his head on the edge of the platform. Happens. The place is a death trap." "He lost his footing in a station nobody has used since 2014, at night, in a suit and polished shoes, with no torch." "Drunk, probably. Or on something. The tox screen will tell us." Quinn did not answer. She was looking at the man's left hand, which was curled loosely against his ribs. Between his fingers sat a small disc of bone, yellowed and smooth, carved with a spiral that had been worn almost flat by handling. "Did you bag that?" "Not yet. I was going to get to it." "Get to it now. Don't touch it with your bare fingers." Fenwick pulled on a glove and worked the token free with the care of someone who had been told about the last officer who had handled a cursed item. He held it up to the torchlight. The spiral seemed to catch the beam and hold it a moment longer than it should have. "Looks like a bit of old ivory," he said. "Or a button." "Buttons don't have that much wear on them." Quinn let her gaze drift along the platform. Dust lay thick on the concrete, grey and undisturbed except for a single line of scuffs running from the stairs to the body. Someone had walked that path. But the scuffs were narrow, each print pressed deep at the heel, a long stride. They did not match the dress shoes of the dead man. They were too large. She rose, her left wrist catching the light. The worn leather strap of her watch had darkened with years of sweat, and she tapped its face once out of habit. Twelve minutes past three. She glanced at the dead man's own wrist. His gold watch had stopped at the same time. "Coincidence," Fenwick offered. "I don't believe in them when I'm standing in a hole in the ground." Near the tracks, half-buried in grit, something glinted. Quinn walked to it, stepping wide of the scuffs, and knelt again. A small brass compass lay face down. The casing had a bloom of verdigris along its rim, green as old pennies. She eased it over with the tip of a pen. The face was etched with a ring of tiny marks, each one a jagged little symbol that seemed to crawl when she looked at it directly. The needle was not pointing north. It was trembling, swinging in short arcs, and then it settled toward the far end of the tunnel where the black mouth of the track vanished into nothing. "Sir, that's a bit of a novelty shop thing, isn't it?" Fenwick said, peering over her shoulder. "Tourists buy them down Camden Lock." "Tourists don't buy compasses that point at the dark." Quinn kept her voice flat. "And a tourist doesn't leave one on a dead man's trail with the needle locked on the tunnel." "You're reading too much into a broken toy." "Am I?" She turned the compass so the needle caught the torchlight. "Then tell me why the dust is disturbed on this side of the track but not the other. Two sets of tread come down to the rails, and only one goes back up. Whoever walked out of here wasn't carrying a body, and didn't need the stairs to get out." Fenwick followed her gesture and frowned. He crouched, sweeping his torch along the rail bed. The second line of prints was faint, almost a smear, and ended at the wall beside a blackened archway that had once held a ticket gate. Nothing came out of the wall. "They vanished," he said slowly. "They didn't vanish. They walked through a door that you and I cannot see." He stood, rubbing the back of his neck. "Ma'am, respectfully, we're not in the business of—" "I'm in the business of the body." She pointed to the man's collar. "Look at his neck. No ligature. No bruising on the throat. Now look at his fingernails." Fenwick leaned in. The nails were pale and perfectly clean, but the tips of the index and middle fingers were stained a faint blue-black, like ink that had dried and cracked. "Some sort of dye?" "Or something burned into him, the same way that bone token was burned into the sweat on his palm." Quinn straightened, and her knees protested. "He wasn't running from anything when he came down here. He was carrying that token to get in, and somebody arranged him so the stairs would look like the cause. Somebody who knew exactly how long a man's watch takes to stop when it's been wound too tightly." The lights from the platform overhead flickered once, then steadied. Somewhere in the tunnel a drip of water struck the rails, a sound like a dropped coin. Fenwick's pen had gone quiet. "You think he was murdered here." "I think he was put here," Quinn said, and lifted the compass once more. The needle swung, hesitated, and pointed straight at her.
