The green neon above the Raven's Nest had burned through two hours of rain by the time Tomás Herrera stepped out. Quinn watched him from the recessed doorway of a shuttered chemist across the street, a paper cup of coffee gone cold in her hand. He paused under the sign with his hood down, letting the green light find his face, and turned a small canvas bag over in his grip like he was checking it still had a bottom. When the bar door swung shut behind him she caught a slice of the interior through the gap — old maps on the walls, photographs in black and white — and then the night closed over it again. He turned his collar up and walked north. She gave him half a block and one parked van. He took the back ways out of Soho, and he never once looked like a man in a hurry, which told her everything. Hurried men had somewhere to be. Herrera was working. He paused at shop glass and bus shelters, watched reflections without moving his head, doubled back twice around the same shuttered pub. In a dark window her own reflection kept pace with her, the rain having pasted her salt-and-pepper crop flat to her skull, jaw set, brown eyes that gave nothing back to the glass. She checked the worn leather band of her watch. Old habit. It told her he was running fourteen minutes ahead of the schedule she'd built for him. Soho fell away behind them street by street. By the time the pavements turned to Camden cobbles she had the measure of his route: north, always north, no buses, no cabs, nothing with a camera in it. Camden swallowed them both. The market stalls stood chained under tarps, the lock gates dripped, and the canal lay black and pockmarked with rain. At the rail bridge he stopped. A night bus came down the high street with its windows lit, and when the headlights swept the pavement they found her standing in the open, twenty metres off, warrant card rising in her hand. He ran. "Tomás Herrera!" He threw a look over his shoulder, curly dark hair whipping, and put a low wall between them. He dropped onto the towpath with his sleeve rucked to the elbow, an old scar showing pale against the olive skin before the fabric fell back over it. "Go home, Detective!" The words reached her in pieces, torn apart by the wind. "You don't want this!" "Stop running and it stays civil!" "You don't know what tonight is!" "I know you run this route every full moon." She took the wall the way he had, landed rolling, came up moving. "Three months of deliveries, Herrera. I counted!" He spat something in Spanish that needed no translation and lengthened his stride. The Saint Christopher medallion had come free of his collar and swung at his throat, throwing silver where the gas lamps allowed it. The bag bounced against his ribs. Rain needled the canal, and the canal took it without a single ripple showing. He vaulted a site fence where the hoarding had come loose, and something fell. It hit the paving ahead of her with a bright click and skittered — a disc the size of a two-pound coin, yellowed like an old tooth. He landed, spun, his hand already out— "No—" —then made his choice. He left it. He ran. She snatched the disc without breaking stride. Bone. Carved all over with a knot of lines too fine to read at a sprint, and warm. Warm the way a held hand is warm, except nobody had been holding it. "Last chance to keep this simple!" He cut off the towpath at the lock and threw himself through a gap in the hoarding — plywood painted to look like brickwork, a flaking sign screwed to it, LONDON UNDERGROUND: NO PUBLIC ACCESS — and dropped into the dark on the far side. She reached the gap and stopped. Warm air came up out of it. It smelled of copper and incense and, underneath both, of a match struck and drowned. Amber light climbed the stairs from somewhere deep, and it flickered, but it didn't move the way flame moves — it pulsed, slow, like something breathing. Under the rain she could hear a murmur down there, the sound of a crowd doing business, and music from no instrument she could name. Eighteen years in the job told her to hold the line, key her radio, let the machinery come to her. She keyed it anyway. "Control, this is Quinn, 4471. I require backup at Camden Lock." Static. She stepped closer to the gap and tried again, and this time the static bent. It pooled and thinned, pooled and thinned, the way a voice sounds through water, though no voice surfaced. The last radio that had gone quiet on her had cost her Morris. Three years, and she still couldn't get a straight answer about that night out of anyone, or out of any file. Law ended at the plywood. Whatever the clique moved through this city, whatever Herrera carried in that bag every full moon, it went on down those stairs. Behind her stood streetlights she could name and a whole world that would ask why she'd let him go. Ahead, far below, Herrera's shape crossed a stretch of lamplight, bag clutched to his chest. "Sod it." She ducked through the gap. A doorman unfolded from the shadow at the bottom of the first flight, big through the shoulders and dressed like a mourner, and his eyes caught the amber light and held it the way a cat's do. "Token." His hand came out, palm up. The nails were the colour of horn. She looked at the hand. Then past him, down the stairs, to where the murmur of the market rose and Herrera had gone out of the lamplight. Everything she'd told herself on the street about waiting, about doing this right, had gone down ahead of him. She set the bone disc in the sentry's palm. He placed it between his back teeth and bit. Bone clicked. He turned the disc over once, pocketed it, and studied her the way a man studies the label on an unfamiliar tin. "New face." "I'm following somebody." "Rules." He stepped aside, just far enough for one. "Buy nothing. Sign nothing. Keep your hands off anything that looks back at you." She took the stairs the way she took everything, straight down the middle. The steps were worn to shallow spoons. At the bottom, an arch of glazed tiles framed a platform, and set into the wall in mosaic letters was the name of a station that appeared on no map she had ever ridden. Lanterns hung from old cable runs in strings. Stalls crowded the platform and spilled down onto the trackbed — glass jars with things turning slow circles inside them, a tray of teeth sorted by size, bottles that fogged from within — and the crowd moved between them in hoods and high collars, human-shaped, most of them. "Herrera!" Every head on the platform turned. Some of them turned further than heads should. He had stopped between two stalls, bag hugged to his chest, the medallion hanging dead still against his shirt. Warm brown eyes, wide. "Quinn." He backed up a step. "Whatever you think I did—" "Turn around. Hands where I can see them."
