The lift to the disused platform had been out of service since 1974, so Quinn took the stairs. Two hundred and forty steps, by her count, each one slick with condensation. A uniformed constable met her at the bottom and handed her a torch, and she found she did not need it. Arc lamps on tripods flooded the platform in flat white light. "Detective." Eva Kowalski stood beside the far tripod with her satchel clutched to her ribs, curls escaping from a knot at the back of her head. She tucked a strand behind her left ear. "I got here twenty minutes ago." "I know. The desk sergeant logged you." Quinn ducked under the tape. "You told him you were with the Museum." "I am with the Museum." "You're a research assistant. I asked for someone who could read the markings." "I can read the markings." Eva pushed her round glasses higher. "That's the problem." Quinn crouched at the platform edge. The body lay on its back between two rusted benches, a man in his fifties, grey suit, no coat. His mouth hung open. His lips had gone the blue-white of skimmed milk. Chalk lines, or something like chalk, ringed him in a circle of interlocking curves. "Tell me what you see," Quinn said. "A ritual killing." Eva spoke fast, the words tumbling. "Those are binding sigils, Mesopotamian in structure but corrupted. Someone laid him in the centre to contain something. Or to call it. The wounds—" "There are no wounds." Eva stopped. "Look at him." Quinn tilted her head at the corpse. "No blood. No bruising at the throat. No ligature marks. Pathology will tell me more, but I've seen forty drownings, and this man has the froth at his nostrils." "He's drowned?" Eva laughed, a short cracked sound. "Down here?" "That's what doesn't sit right." Quinn stood, her knees popping. She pressed her thumb against the worn leather strap of her watch, a habit she had never shaken. "The nearest water main is three hundred yards east. The tunnels are dry. The constable who found him says the floor was dry. And his suit—" She pointed. "Bone dry. Not damp at the cuffs, not even creased. A man who drowns in a bath still gets his sleeves wet." "So someone moved him." "Did they?" Quinn walked the perimeter of the circle, boots crunching on grit. "Come here. Tell me about the dust." Eva edged closer. Grey powder lay thick across the platform, a century of brake dust and soot and rot. In front of the benches it had been scraped to bare concrete in long parallel bands. "Something was dragged?" "Something was set down. Over and over." Quinn pointed with her torch. "Those aren't drag marks. Look at the edges. Sharp, square. A rectangle, then another beside it, then a lane between them. Eight, nine, ten of them, running the length of the platform." "Stalls," Eva whispered. Quinn's head turned. "Stalls." "I mean—" Eva's hand flew to her hair. "Like stalls. Market stalls. That's what they look like." "That's what they look like." Quinn let the silence stretch. "Forty years I've been walking crime scenes, or near enough, and I've never seen a scene that looks like a car boot sale. Somebody held a gathering down here. A big one. Hundreds of feet wore that path along the tunnel mouth. See how the grit's ground to powder there? Then everyone packed up and left, and they left him." "Or they were the ones who killed him." "A crowd that size? No. You don't murder a man in front of hundreds, then tidy up so neatly you sweep the dust from your stall footprints." Quinn moved to the body and knelt again. "Whoever cleared this place did it fast, but with care. They took the tables, the lamps, the crates. They didn't take him, and they didn't touch the circle." "Because the circle is the message." "Is it?" Quinn drew a pen from her coat and pointed to the nearest curve of the chalk. "Your Mesopotamian sigils. Tell me which way they run." Eva bent. Her lips moved. "Clockwise. Inward." "And the ones at his head?" A long pause. "Outward." "So the design contradicts itself. Someone drew this in a hurry, or drew it to look like something it wasn't." Quinn kept her voice level. "A ritual meant to bind wouldn't spiral both ways. This is stage dressing, Miss Kowalski. Somebody wanted a detective to see occult nonsense and go chasing cults through Camden, while the real question sat dry and quiet in the dust." "What real question?" "Why a drowned man is lying in a tunnel with no water." Quinn slid two gloved fingers into the dead man's jacket pocket. She withdrew a small, pale disc, yellowed as an old tooth, drilled through the centre with a hole no wider than a pencil lead. She held it to the light. Fine lines had been scratched across its surface. "And why he's carrying this." Eva's face lost its colour beneath the freckles. "Where did he get that?" "You tell me. It's bone. Human, if I'm any judge, though I'll wait for the lab." Quinn turned it over. "The same lines are cut into the tile behind you. Small, low down, near the skirting. Almost like someone marked the entrance." Eva looked. Quinn watched her look. The girl's mouth tightened, and her hand crept to her ear again. "You've seen these before," Quinn said. "In a catalogue. At work." Eva swallowed. "Restricted archive material. It could mean anything." "It could. But you flinched." Quinn slipped the token into an evidence bag and sealed it. "So let's try the other pocket." She reached across the body. Her fingers closed on something cold and heavy, and she drew out a small brass compass, its casing furred with green verdigris. Etched glyphs crowded the face, tiny and precise, and the glass had been polished by years of thumbs. The needle should have pointed north. It didn't. It spun, slowed, lurched, and locked on the blank tiled wall at the platform's end. Quinn rose. She took a step to the left. The needle followed the wall. She took a step to the right. It followed again, steady as a dog on a scent. "There's nothing there," Eva said, too quickly. "There's a wall." Quinn stared at the needle, then at the wall, then at the girl beside her. "Which is precisely what a man would say who'd never checked behind it."
