The Northern line ran somewhere above her, a faint tremor in the concrete that Harlow Quinn felt through the soles of her shoes. Ahead, the uniformed constable's torch swept across tiled walls gone the colour of weak tea, lighting up advertisements for cigarettes and a soap that had been discontinued before she was born. "Mind the step, ma'am," the constable said. "It's soft." It was. The platform had been sealed for nearly forty years, and the dust lay thick enough to take a footprint like wet plaster. Quinn stopped at the foot of the stairs and let her eyes adjust. Camden's old Kentish Road platform had no business being open at all. Someone had cut through a maintenance grille and left the bolts unscrewed, and that was the first thing she wrote down. Detective Constable Ray Okafor was waiting beneath the work lamps, hands in his coat pockets, his breath showing in the cold. He was thirty-two, sharp in the way young officers were when they hadn't yet learned what the job cost. He had called her in on a Saturday, and he had the look of a man who wanted to be told he was right. "Dominic Hale," he said, nodding at the shape on the concrete. "Twenty-nine. Known to us for possession, nothing violent. Found by a pair of urban explorers at half five. Filming for their channel, if you can believe it." "Did they touch him?" "Only to check for a pulse. They say he was already cold." Quinn crouched beside the body. The man lay on his back at the base of the far wall, one arm flung above his head as though he had reached for something. His eyes were half open, pupils blown wide under the lamp. His jacket was good wool, expensive, and it had been buttoned wrong, one side hanging lower than the other. "Fell from the gallery," Okafor said. "There's a broken rail up there. He's had a few, clearly, and maybe something else. Looks like he went over and hit his head on the way down." Quinn looked up. The gallery was twelve feet above them, its railing rusted into lace. It was a plausible story. It was also the story a tired man would tell himself at the end of a long night. "Show me the dust," she said. Okafor frowned. "The what?" "The floor, Ray. Walk me through the prints." He lifted the torch and played it across the platform. There, in a pale grey skin of dust, was a single line of boot impressions coming from the stairs and running straight toward the sealed brick wall at the end of the platform. Large, heavy soles, the tread clear and deep. They ended a yard short of the bricks. "He walked in," Okafor said. "Pissed, probably. Lost his balance." "Where's the way out?" "What?" "Those are the only prints on this floor. Nobody came down those stairs after him. Nobody left. Hale walked into a wall and then, what, lay down and died neatly with his arm up?" She tapped the air above the dead man's hand. "And look at the scuffs on his heels. They're grooved, not scraped. He was dragged backward at some point, and the dust around him shows nothing. No drag marks at all." Okafor's jaw tightened. He looked at the dust and then back at her, and she could see him deciding whether she was clever or simply stubborn. "Could be the explorers. They were all over the place before they called it in." "They say they only touched his neck." "Then they're lying, or they're thick." "Or the floor was undisturbed when they arrived," Quinn said, "and whoever did this knew how to leave no tracks at all." She stood and pulled a pair of gloves from her coat. The constable with the torch shifted his weight, uneasy, and kept the light steady on the dead man's hand. Quinn knelt again and eased the fingers open. A brass compass lay in the cup of his palm. It was small, no bigger than a pocket watch, its casing crusted with verdigris where the metal had been handled and then left to decay. The face was etched all around with fine, interlocking sigils, the kind she had seen once before in a damp evidence locker three years ago, in a bag beside a coat that still smelled of her partner's aftershave. Her left wrist itched under the worn leather strap of her watch. She did not look at it. The needle was trembling. It was not resting on north. It pointed past Okafor's shoulder, past the lamps, toward the brick wall where the boot prints ended. "What's that?" Okafor asked. "A compass." "Doesn't look like one of ours." "It isn't." She watched the needle quiver, then steady, then quiver again. Like something breathing. "It's pointing at the wall." "Magnetic interference. The tunnel's full of iron." "Is it?" She rose, took the torch from the constable without asking, and walked to the bricks. Up close, the mortar was newer than the rest of the station, the joints still pale. Someone had repointed the wall recently and carefully. She ran her gloved fingers along a seam and felt the faint cold draw of air, as though the wall were breathing out. "Ray. His coat pocket. The left one." Okafor hesitated, then bagged his hand and reached in. He came out with a small grey disc, smooth and yellowed, threaded on a cord. He held it under the lamp. Carved into its face was a ring of tiny teeth, arranged like a key. "Bone," he said, and the word sounded foolish in his mouth. "It's bone." "It's a ticket," Quinn said. "Or it's a receipt. And he didn't have a phone, did he? Or a wallet, or a single note in his pockets. Someone emptied him and left him the things they didn't want." "Ma'am, if you're suggesting this is connected to the cases you've been chasing—" "I'm suggesting that a man who was dragged across a floor, with no tracks, had a compass in his hand pointing at a wall that was freshly sealed, and a token in his coat that opens something." She turned the bone disc over. The cord was new, its knot tied with a precision that reminded her of the way certain people in her last case had folded their hands. "And I'm suggesting that his eyes are dilated, but there's no vomit, no froth, no smell of alcohol on his breath. He didn't drink himself into this, Ray. He was made to stand still." The constable with the torch made a small sound and looked away. Quinn crouched once more beside the body and studied the wrist that had been flung above the head. Beneath the cuff of the good wool jacket, the skin was marked with a faint pale band, the shape of a strap, as though someone had worn a watch there for years and only recently taken it off. She thought of her own watch, of a Saturday three years ago, and of the particular stillness in a room when a man you trusted stopped breathing for no reason a doctor could name. "Get the wall opened," she said. "Carefully. And nobody touches that compass until I've photographed every sigil on it." Okafor opened his mouth, closed it, and nodded. Quinn stood, pulled off one glove, and at last looked at her watch. Its hands had stopped at fourteen minutes past two. She had stopped looking at it three years ago, and she was not going to look at it now.
