The stairs down to the disused platform had been sealed since 1947, according to the brass plaque bolted to the tiling, but someone had peeled back the hoardings as neatly as a tin of sardines. Quinn ducked under the tape and let the damp take her. Cold crawled up from the tunnel mouth the way it always did in these places, carrying the ghost of creosote and something else tonight — something sweetly floral that didn't belong eighty feet beneath Camden. "Watch the third step from the bottom," DI Renner called up. "It's gone soft." She placed her boots carefully, the leather strap of her watch pressing against her pulse. Eighteen years on the job and she had learned to trust the small complaints of her own body. Her wrist itched when a scene was wrong. It had been itching since she clocked on. The platform opened before her in a wash of sodium worklights. Tiles the colour of old teeth. A wooden bench rotted to lace. And at the far end of the curve, where the advertising frame still held a faded poster for Bovril, the body. "Male, mid-forties," Renner said, falling in beside her. He had the tight, pleased look he always wore when he thought a case would close before the paperwork got heavy. "No ID. No phone. We're figuring a rough sleeper got caught out — hypothermia, maybe a bad hit. There's a syringe by the wall." "Show me the syringe." He pointed. Quinn crouched. The needle was clean. Too clean. The glass barrel hadn't even collected the fine grey dust that coated every other surface down here like a second skin. "Somebody planted that in the last hour," she said. Renner's smile thinned. "Harlow —" "Look at the tiles around it." She drew a circle in the air with one gloved finger. "No scuffs. No prints. He didn't sit down here and use. Someone put that syringe down after the dust settled and left." She stood, knees clicking, and moved to the body. He lay on his back with his arms at his sides, palms up, as though he'd decided to sleep on the platform and simply stopped. No contortion. No vomit. The floral smell was stronger here, cloying. She leaned in until her breath fogged the plastic of her face shield and looked at his mouth. His lips were blue. Not the slow marbled blue of cold. A bright, almost cheerful blue, like ink. "Overdose wouldn't give you that," she murmured. "Cyanosis can present —" "Not like that." She straightened. "Who called it in?" "Anonymous. Payphone on Camden High Street. Male, thirties-ish." "Payphone." She let the word sit. There were perhaps six working payphones left inside the North Circular. "Where did Forensics find his shoes?" Renner blinked. "His — he's wearing shoes." "He's wearing a left shoe." She pointed. The man's right foot was in a black sock, the sock so pristine that she could have believed it had been pulled on thirty seconds before they arrived. The left foot wore a scuffed brogue. "He walked down here in a pair. Somebody took one off." "Or he lost it in the tunnel." "Then it would be in the tunnel." She stepped around the body, scanning the platform edge. "And it isn't." Renner's jaw set. He was a good copper, Quinn reminded herself, and a decent man, but he had the dangerous habit of preferring his first theory to his second. She used to be the same. Then Morris had died, and she had learned that first theories were usually what a killer wanted you to have. She crouched again, closer this time, and let her eyes go slow. Eighteen years. You trained yourself to see the tenth thing, not the first. The first thing was always what the scene was shouting at you. The tenth was what it was trying to hide. There. Under the cuff of his jacket, where his wrist turned. A thread of something pale had caught in the weave of his sleeve. Not hair. Not fibre. Bone-white and smooth, like a shaving of ivory. She eased it free with her tweezers and held it up to the light. It was a sliver of bone, no larger than a fingernail paring. An edge of it had been polished flat and incised with a mark she could not read: three strokes crossing a half-circle, so neat they might have been printed. "Huh," Renner said, peering over her shoulder. "Some druggy trinket." "Is it." She bagged it. The itch in her wrist had become a hum. She swept her gaze across the body again with this new fact in her pocket, and the scene rearranged itself around it, the way a face sometimes did when you finally noticed the wig. The floral smell — not perfume. Something burnt. A resin, maybe. The arrangement of the body — too tidy. Ceremonial. His left hand. His left hand was curled, not quite closed. She had registered it and dismissed it. Now she lifted the wrist carefully and turned the palm. Nestled in the hollow of his fingers, half-hidden by the curl of them, sat a small brass compass. Its casing was furred green with verdigris, older than anything a rough sleeper should have been carrying. She turned it in the evidence light. The face was etched with a lacework of symbols she half-recognised from the sliver of bone — the same hand, she thought, or the same tradition. The needle twitched. Not north. It was pointing at the tunnel mouth, and as she shifted the compass in her palm the needle corrected itself, stubbornly, toward the dark. "What the hell is that," Renner said. His voice had gone flat. "I don't know yet." She held the compass a moment longer than she needed to. Something cold moved up her forearm from it, and for a heartbeat she was back in a warehouse in Deptford three years ago, kneeling in Morris's blood, and Morris was saying something she still could not quite remember, something about a door that shouldn't have been there. She sealed the compass in a bag and stood. "Get Forensics back down here," she said. "Everything they photographed — I want it rephotographed. Tell them to stop looking for a junkie and start looking for whoever knelt beside him." "Harlow, we've got a working theory —" "You've got a story someone told you." She nodded at the body. The blue mouth. The single shoe. The polished bone. "He didn't come here to die. Somebody brought him. And somebody wanted us to find him exactly like this." She turned back toward the stairs. Behind her, the needle in its little brass house pressed patiently, silently, toward the dark.
