The Camden Town platform had been dead for seventy years, and it smelled like it. Harlow Quinn stood at the bottom of the stairs with her torch angled low and let the beam travel the length of the tiles. Mildew bloomed in the grout. Advertising posters from a decade no one remembered peeled off the walls in strips. Someone had strung a line of blue police tape across the turnstiles, and the tape hung limp, as if the air had lost interest in it. "Ma'am." DC Tom Halloran came down the stairs two at a time, his breath steaming. He was twenty-nine, eager, and he had already decided what this was. "Uniform says the squatters found him this morning. Male, mid-thirties. No ID." "Cause?" "Looks like an overdose. Pupils blown, lips blue. Probably some bad batch from the clubs on Chalk Farm Road." He shrugged. "Happens every winter." Quinn didn't answer. She walked to the edge of the platform where the body lay against the tiled wall, knees drawn up, one arm flung over his face as if he had been shielding his eyes from a light. The coroner's van was not yet here. The scene was hers until it wasn't. She crouched. Her knees protested, a small reminder of forty-one years and eighteen of them in uniform and plain clothes. She did not look at the face yet. She looked at the floor. "Tom. Who else has been down here?" "Just the lads who found him and the constable on the gate." "Look at the dust." He crouched beside her, squinting. The platform was furred with grey, the kind of dust that took a footprint like wet cement. Three sets of boot prints led from the stairwell to the body, scuffed and overlapping, the squatters' prints and the constable's. Then there was a fourth set, narrower, leading from the far end of the platform, where the tunnel mouth yawned black behind a rusted gate that should have been chained shut. "Those go in," Tom said slowly. "They don't come out." "Follow them." He followed them with his torch. They ran straight to the body and stopped. No second line led away. Not even a drag mark. "So he came out of the tunnel," Tom said. "Wandered over, sat down, took something." "Look at his hands." The man's right hand lay open on his thigh. Quinn had already seen what was in it: a bone token, yellowed and carved with a crude spiral, pressed so hard into the palm that the skin around it was reddened. A ritual object. Or a pass. She had seen tokens like it once before, in a file she had never been meant to open, three years ago, in a case that had ended with DS Morris's body in a morgue drawer and a report that said nothing at all. She did not say that aloud. "Could be a keepsake," Tom offered. "Could be." She reached for the man's left wrist, careful, and turned it toward the torch. A thin watch lay against his skin, its hands stopped at twenty past three. Quinn checked her own watch out of habit. Her worn leather strap was warm from her pulse. She had been on this platform perhaps eight minutes. Whatever time that was, it was not the time on his. "Stopped," Tom said. "Batteries, maybe." "It's mechanical." Quinn turned her attention to the tiles beside the body. There, in the grey dust, half-hidden under the man's hip, was a faint circular impression with a smaller mark at its center. She tilted her torch until the grain of the dust caught the light. A ring, perhaps two inches across. Ridges around the edge, almost like etched lettering. Something had sat here, something heavy and round with a sharp point at its heart, and it had been lifted away recently, because the edges of the impression were still crisp. Verdigris had flaked into the dust beside it, a fine green-grey powder. Copper, oxidised for years. "Tom, bag me a sample of that. Careful." "Ma'am, it's dust." "It's a compass," she said quietly, and watched his face change as he realised she meant it. She had seen the sigils once, under the glass of an evidence locker. Protective marks, the kind carved by people who knew exactly what the Market could do to a man who walked out of it without paying. The squatters had seen nothing, Tom said, because the squatters had been drunk. The constable had seen nothing because the constable had been sick at the top of the stairs. There was no drug paraphernalia. No bottle. No needle. A man who had died of a bad batch would have left something behind: a cup, a crumpled wrapper, a phone. This man had left only a token, a stopped watch, and a set of footprints that walked into the dark and never returned. Quinn stood, her knees cracking, and looked down the tunnel where the dark held its breath. "He didn't overdose, Tom," she said. "He was waiting for someone to come back for him, and they didn't." Behind her, very faintly, the tape on the turnstile stirred, though the air was perfectly still.
