Herrera ran before Quinn reached the middle of the road. She had watched him leave the Raven’s Nest just after one, the bar’s green neon washing his dark curls and black medical bag as he paused beneath the sign. He had driven north without speeding, signalled every turn, and parked neatly in Camden. Careful behaviour for a man with nothing to hide. Quinn had followed at a distance, certain he meant to lead her somewhere. Now he was sprinting through the rain with the bag clamped against his ribs. “Stop! Police!” Herrera glanced back. Water streamed down his olive face; his warm brown eyes looked almost black beneath the streetlamps. Then he dodged between a shuttered pharmacy and a chicken shop, and vanished into an alley. Quinn swore and went after him. Rain needled her face and plastered her closely cropped salt-and-pepper hair to her skull. Her shoes struck water with every third step. Herrera was younger by twelve years and faster in a straight line, but the bag made him clumsy. He took the alley’s first turning too wide, shoulder grazing brick, and she gained two strides. At forty-one, Quinn no longer mistook speed for control. She paced her breathing and watched his shoulders, not his feet. Shoulders told you where a man intended to go before his pride had finished lying about it. She tugged her radio from her coat. “Quinn, in foot pursuit. Male suspect, Tomás Herrera, moving north through Camden. Medical bag, dark coat.” Static ate Control’s reply. She caught only “units” and, a moment later, “six minutes.” Six minutes was an invitation to do something stupid. Herrera kicked a rubbish bin into her path. Quinn planted one hand on its lid and vaulted it. The metal buckled under her palm; she landed badly, pain spearing through her right knee, but kept moving. Ahead, Herrera’s Saint Christopher medallion had slipped free of his shirt. It swung wildly on its chain, flashing silver each time he passed beneath a light. “You’re making this worse!” she shouted. “Go back, Detective.” His voice carried no breathlessness. Only urgency. “Stop and I’ll consider it.” He ran faster. They burst onto a road where the late traffic had thinned to isolated cars. Herrera crossed against the lights. A taxi slammed on its brakes and skewed sideways, missing him by inches. Quinn put up a hand without looking and followed through the spray. The driver’s horn dopplered after them. Herrera ducked beneath scaffolding, shouldered through a door marked NO ACCESS, and disappeared. Quinn reached it four seconds later. The door opened onto a narrow service passage behind a row of shops. There were no lights except the red glow of an alarm above the far exit. She drew her extendable baton but did not open it. Herrera had run, not fought. So far. “Tomás,” she called. “There’s nowhere clever left to go.” Something clattered beyond the red exit. She found him at the end of the passage, dragging aside a sheet of corrugated hoarding. His sleeve had ridden up as he hauled at it, exposing the old knife scar along his left forearm. For an instant his eyes met hers through the gap. “Don’t follow me below,” he said. Then he was through. The space beyond had once been an entrance to the Underground. A condemned one, judging by the rusted gate and the sign wired to it: STRUCTURE UNSAFE. NO PUBLIC ACCESS. Herrera had forced the gate far enough to slip through. Wet stairs descended into darkness. Quinn stopped at the top. Sound rose from below. Not water. Not rats. Voices. Dozens of them, layered over the hollow strike of metal and something that might have been music played through a wall. The abandoned station smelled of damp stone, ozone, and a sweetness so dense it made her think of rotting flowers. She checked the worn leather watch on her left wrist. One twenty-six. Backup would be looking for her on the street, if her transmission had gone through at all. Herrera’s footsteps echoed down the stairs. Quinn went after him. The steps were slick with black silt. Twice she had to catch the wall. Old directional signs pointed toward ticket halls and platforms, their lettering scabbed by damp. The voices grew louder. So did another sound: a slow, regular tapping, like someone patiently testing a pipe with a fingernail. Her radio hissed. She raised it. “Quinn. Descending disused station entrance, east side of—” The hiss deepened into a chorus of whispers. She nearly threw the thing away. Instead she switched it off, told herself the circuitry had taken water, and continued down. The stairwell opened into a vaulted concourse. At its far end stood an iron gate where no gate belonged in the old plans she had studied before tonight’s surveillance. A bald man in a railway porter’s coat sat beside it on a wooden stool. His collar was buttoned to the throat despite the heat rising from below. Herrera stood at the gate, breathing hard. He held up a small white disc. The porter looked at it without moving his head. “Token.” Herrera pushed it closer. The disc was the colour of old ivory, but no ivory Quinn had seen carried that faint translucence at the edge. Bone. The porter opened the gate. Herrera slipped through. As he shoved the token toward his coat pocket, it struck his wet knuckles and fell. He did not notice. It spun across the threshold, struck the wall, and rolled back toward Quinn. Beyond the gate, light moved along a crowded platform. Not lamplight. Not anything she could comfortably name. Stalls had been erected between the tiled pillars. Their awnings sagged with moisture. People packed the narrow aisles, some in ordinary coats, others in clothes that seemed borrowed from different centuries. Above them hung a chalkboard: VEIL MARKET FINAL TRADING NIGHT IN CAMDEN Beneath the words someone had drawn a full moon. Herrera turned and saw Quinn at the foot of the stairs. “Detective,” he called. “Don’t.” There was no triumph in his face. No contempt. He looked afraid. Then the crowd folded around him. The porter began to close the gate. Quinn picked up the token. It was colder than the stairwell. A design had been carved into one side: an open door with a single vertical line through it. The same design, she realized, had been inked on the inside of DS Morris’s wrist when his body was found three years ago. The pathologist had called it a tattoo. There had been no record of Morris ever getting one, and Quinn had seen every inch of his arms often enough to know he hadn’t. Her hand closed around the bone. The porter watched her. “Token or turn around.” She showed him her warrant card. He leaned forward, studied it, and sat back. “That’s tin.” “Metropolitan Police. That gate stays open.” “No,” he said. It was the flatness of it that stopped her. Not defiance. Simply a man stating that rain fell downward. Beyond him, something laughed in a glass bottle. Quinn looked toward the sound and saw a vendor stopper a cloudy jar. The laughter stopped. Her mind offered explanations with increasing desperation. An illegal rave. A drug market. Performers in costume. An elaborate set built by people with too much money and no fear of prosecution. None explained why the platform appeared to extend farther than the station above it. The porter held out his hand for the token. Every hour of Quinn’s eighteen years in the job told her to wait. Unknown location. No communications. No reliable description for backup. One suspect who knew the ground and dozens of potential hostiles beyond the gate. Entering alone would be indefensible. Morris had gone below alone too. The official findings on his death had contained the words unexplained and inconclusive, arranged with great care so no one had to write impossible. Quinn had spent three years telling herself that procedure would have saved him. That if he had waited, if she had reached him sooner, if either of them had obeyed the rules they taught to children in uniform, he would still be complaining about her coffee. The porter’s fingers curled impatiently. Quinn looked at the chalkboard again. Final trading night. Whatever this place was, it would not be here when backup arrived. She scored an arrow into the soft brick beside the stairs with her baton tip and added a Q beneath it. A poor trail, but better than none. Then she put away her badge and gave the porter the token. He dropped it into a leather pouch. “Market peace holds under the roof. No seizures. No badges. No blood unless you mean to sell it.” “I’m looking for one man.” “Everyone is.” He opened the gate. Quinn stepped through. The iron struck home behind her with a note she felt through the soles of her shoes. The watch on her left wrist gave a tiny mechanical stutter. Its second hand jumped backward, hesitated, and resumed. She did not look at it again. Inside, the market smelled of wet wool, copper, crushed herbs, and smoke. Along the old platform edge, jars of crimson liquid pulsed gently though nothing touched their shelf. A sign above another stall read UNLICENSED ALCHEMY in neat capitals. Farther on, a veiled woman sold envelopes from a locked cabinet. QUESTIONS ANSWERED, her sign promised. NO REFUNDS ON BAD NEWS. A man brushed past Quinn carrying a birdcage covered in black cloth. Something inside whispered his name until he struck the bars. Quinn kept moving. Wonder was a luxury. Fear could queue behind it. She caught sight of Herrera’s bag near the mouth of the west tunnel. He was forcing his way through the crowd, no longer running but still fast. Quinn followed, using her height and shoulders, ignoring the protests in several languages. When he looked back, she was close enough to see the resignation cross his face. He turned toward the tunnel. Quinn lunged, caught the bag’s strap, and hauled him backward. Herrera stumbled. She drove him against the tiled wall and pinned his left arm before he could recover. The old scar pressed rigid beneath her fingers. “Enough,” she said. He did not struggle. “Let go.” “You ran from police.” “There’s a boy through that tunnel with a wound I can’t treat in the street.” “Convenient.” “Yes,” Herrera said, anger finally roughening his voice. “Very convenient for him.” His medical bag had fallen open. Quinn saw bandages, a sealed syringe, two bottles marked in handwriting, and a child’s woollen glove soaked dark with blood. She did not release him. Around them, the market had gone quiet. Not all at once. The silence spread by stalls, as though each trader had noticed something and nudged the next. A shutter slammed. Somewhere glass broke. The tapping Quinn had heard on the stairs stopped. Herrera stared into the unlit tunnel. “We need to move,” he said. “We’re going back to the gate.” “No.” His gaze dropped to her hand on his arm. When he looked up again, his fear had become something older and more tired. “If we’re still standing here when it reaches the concourse, you’ll want walls between you and it. Thick ones.” “What will?” “Stay close to me. Don’t buy anything, don’t accept anything, and if you hear your name, don’t answer.” Quinn almost laughed. Then she saw that his free hand had closed around the Saint Christopher medallion at his throat. “You’re still coming with me,” she said. “If we get out.” She pulled him away from the wall. From the tunnel came the faint crackle of a damaged radio. Herrera froze. A man’s voice spoke through the static, low and familiar, with the slight catch at the end of each sentence that Quinn had once teased him for. “Harlow?” Her grip loosened. She had heard that voice in dreams for three years. Awake, she had sometimes caught it in a crowded station or passing car, always gone before she could turn. Now it spoke from no more than twenty feet away. “Harlow. You took your time.” Herrera seized her wrist. “Detective,” he whispered. “Whatever it says, don’t answer.”
