AI The call had come in at 4:12 a.m., which was the hour Quinn trusted least. Anything before three was still last night's business. Anything after five belonged to the milk vans and the bakers. But 4:12 was the dead middle of nowhere, and in eighteen years she'd learned that nowhere was where the strange things happened.
She came down the service stairs at the old Camden Road platform with her torch low, because the emergency lighting the response team had rigged was doing that thing bad lighting does — it lit the floor and the ceiling and left everything at eye level in a kind of brown fog. The air smelled of rust and wet chalk. Below her, somebody's radio crackled and cut out.
"Morning, guv," said PC Adeyemi at the bottom, holding the tape aside. He looked green under the work lamps. "Watch the third step from the bottom, it's gone soft."
"How long's this station been shut?"
"Nineteen-sixteen, apparently. Sealed in the seventies. Nobody's got a key that works."
Quinn stopped with one hand on the rail. "Then how'd we get in?"
"Door was open, guv."
"Open how?"
Adeyemi hesitated. "Open like it was never shut."
She logged that, the way she logged everything, in the small tidy filing cabinet at the back of her skull, and went down.
The platform was longer than she expected and curved away into black at both ends. Old tiles, cream and oxblood, half of them fallen. Advertisements from another century, ghosted down to their bones: a woman's gloved hand, the word RELIABLE, a shoe. Somebody had swept the platform. That was the first wrong thing. Not swept recently — swept a long time ago and kept swept, the dust pushed into neat berms along the tunnel wall the way a man sweeps a shop floor at the end of a shift, over and over, for years.
The body lay eleven feet from the platform edge, on its back, arms at its sides.
DI Marcus Pell was crouched beside it with his coat pooled on the concrete, which told her he didn't care about the coat, which told her he'd already decided what this was.
"Harlow." He didn't get up . "You look like you slept."
"I did. Two hours, sitting up. What have we got?"
"Male, mid-forties, no wallet, no phone, no keys. Blunt force to the back of the skull, one blow, hard. Somebody brought him down here, hit him, and left." Pell straightened, knees cracking . "You want my read? He came down to buy something he shouldn't. Rough sleepers, dealers, that scene. There's a whole economy in these dead stations. Kid told me last year there's a fella sells stolen bikes out of a ventilation shaft at Aldwych. Deal went bad, someone panicked, done."
Quinn crouched where he had been. She took her time. That was the whole of her method, if she was honest, and she never was, not in front of Pell: she took her time and let the scene talk before she asked it any questions.
The man wore a wool overcoat, good quality, twenty years out of fashion. His shoes were dress shoes, polished, worn down evenly at both heels. Hands soft, nails clean, one callus on the middle finger of the right hand where a pen sits. His face had the settled look of a man who'd been about to explain something.
"No defensive wounds," she said.
"Never saw it coming."
"Mm." She lifted the near hand with two gloved fingers. The sleeve rode up. The wrist was unmarked. "Where's his watch?"
"No watch."
"There's a watch." She turned the arm slightly into the light. A pale band of skin, two inches wide, on a wrist otherwise the same dull colour as the rest of him. "He wore one every day for years. Somebody took it. But they left the coat, which is worth more, and they left" — she opened the coat with the back of her hand — "a signet ring, gold, on his little finger. You panic-rob a man, you don't sit down and select. You take the ring. It's right there."
Pell shifted his weight . "Watch might have been engraved. Traceable."
"Then so's the ring."
"Harlow."
"I'm not arguing, I'm counting." She sat back on her heels. "Keep going. The blow's to the back of the skull. He's on his back, arms at his sides, feet together. If you hit a man from behind and he drops, he goes forward. Face down, arms out, one knee up. He doesn't lie down like he's being measured for a coffin."
"So they turned him over."
"Why?"
"To check he was dead. To go through his pockets."
"Then his coat would be twisted. Look at it." She traced the air an inch above the wool. "Hem's straight. Lapels are flat. His collar's not even rucked. Somebody rolled him, straightened his limbs, arranged his coat, and closed his eyes." She paused. "Somebody who was sorry."
Pell said nothing for a moment. Then, quieter: "Or somebody performing sorry, for our benefit."
She almost smiled. He wasn't stupid, Pell. He was just tired in a way that had gone structural, and tired men prefer explanations that let them go home.
"Second thing," she said, standing . "Where's the blood?"
The concrete under the man's head was dry. Not scrubbed — Quinn had seen scrubbed, scrubbed leaves a halo, a ghost of clean in the dirt. This was ordinary grey floor with ordinary grime, and a dead man with a broken skull lying on it.
"Killed elsewhere," Pell said. "Dumped here."
"Down two flights of stairs and a soft third step, carrying a fifteen-stone man, without touching either wall. Look at the dust on the tiles. There's no smear. No drag marks. No shoeprints but ours and the response team's." She turned her torch on the platform floor and swept it in a slow arc, and the two of them looked at the swept concrete and the neat berms of dust and the absolute absence of any indication that a single living person had ever walked there.
"That's not possible," Pell said.
"No," Quinn agreed. "It isn't."
She walked to the platform edge and shone the torch down into the trackbed. No rails; they'd been lifted decades ago, leaving two long grooves of ballast and a rat's nest of cable. And there, in the dust of the trackbed, so faint she had to crouch and change her angle twice: a track. Not footprints. A single line, smooth, about four inches wide, running from beneath the dead man's position out along the tunnel and into the dark, like something had been dragged . Or like something had trailed behind whoever had walked out.
"Marcus . Come and look at this."
He came, and he looked, and she watched his eyes find the line and slide off it again. "Cable. They pulled cable out."
"There's cable right there, still in place."
"Then a bag. A holdall."
"Sure," she said, and let it go, because there was no percentage in it and because she had already stopped talking to him.
She went back to the body and got down on the floor beside it, cheek almost to the concrete, and looked at the man's face from three inches away.
His eyes were closed. His mouth was slightly open. And on his tongue, dry and grey as a communion wafer, lay a small flat disc of bone the size of a five-pence piece, scored on one face with a mark like a stitched wound.
Quinn's stomach went cold, and not from the floor.
She had seen that shape once before, three years ago, in a photograph she had never been permitted to enter into evidence, taken at a scene where DS Michael Morris had gone in through a door and had never come back out of it. She'd been told , at the time, that the door led to a plant room. She'd been shown the plant room. She'd measured it. It was two feet too shallow.
"Guv?" Adeyemi, from the stairs. "There's a woman up top asking to speak to you. Says she's not press. Red hair, glasses, got a bag full of books. Says she knows what the token means."
Quinn stayed where she was for a count of five, looking at the little bone coin, feeling eighteen years of decorated service tilt under her like the soft third step.
Then she stood, brushed the dust from her knees, and touched the worn leather strap of the watch on her left wrist, once, the way she always did.
"Marcus ," she said. "Nobody touches that man's mouth. Nobody. And get me the sealing records for this station going back to 1916. All of them."
"Harlow, it's a mugging."
"It's a delivery," she said, and went up into the grey beginnings of the morning to meet the woman with the books.
