The rain came sideways off Camden High Street, needling through the gap in Harlow Quinn's collar and pooling in the cuff of her watch. The worn leather had gone black with water. She ignored it. Ahead, a grey coat cut between a shuttered kebab van and a row of overflowing bins, moving with the loose stride of a man who knew every crack in the pavement. "Tomás Herrera." Eighteen years in uniform had sanded her voice down to a flat, clipped edge. "Stop walking." He didn't stop. He glanced over his shoulder, and the sodium light caught the pale ridge of the scar on his left forearm where his sleeve had ridden up. Then he ran. Quinn ran after him. Her knees protested. Her shoes skidded on oil-slick paving, and she lost two seconds at the kerb when a black cab swung past, horn braying. By the time she reached the corner, Herrera was twenty yards clear, weaving through a knot of late-night drinkers who scattered under the awnings. The Saint Christopher medallion bounced against his chest on its thin chain, catching the light each time he turned. "You're making this worse for both of us," he called back, without breaking stride. "Then stop running and make it better." "Detective, if I stop, I'm dead by morning. If you keep following, you'll be the one who gets me killed." She pushed harder. The street narrowed. Shopfronts gave way to hoardings, and the hoardings gave way to a boarded-up entrance at the mouth of an old Tube station. Someone had painted a green neon sign above the next building along, glowing faintly through the downpour, but this entrance held nothing but rot. The sign on the plywood had bleached to the colour of weak tea. CLOSED. LONDON UNDERGROUND. Below it, a sheet of corrugated iron had been bent back on one side, leaving a gap just wide enough for a man to slip through sideways. Herrera went through it without hesitating. Quinn reached the hoarding, put her palm flat against the wet metal, and felt the faint vibration of something moving underneath the city. A breath of warm air rose through the gap. It smelled of damp stone, cloves, and something sweeter underneath that she didn't want to name. She drew her warrant card from her inside pocket, then thought better of it and kept her hand on her hip, near the holster. Her pulse hammered in her ears, steady and uncomfortable. She stepped to the gap. A figure stood on the far side, waiting at the top of a stairwell. Hood up, face swallowed by shadow, one gloved hand extended, palm open. Herrera had already reached the foot of the stairs, but he stopped and turned. His expression in the weak light was tired rather than afraid. He lifted a small object on a length of cord, something pale and carved, and pressed it into the figure's hand. The hood dipped in acknowledgement. The gloved hand withdrew. "Bone token," the figure said, in a voice like gravel sliding down a chute. Then the hood tilted towards Quinn. "You don't have one, Detective Quinn." She didn't ask how it knew her name. "I have a warrant." "Paper doesn't open doors down here." The figure stepped aside, leaving the top step clear, and the warm murmur of voices rose from below, layered with the clink of glass and the sharp, metallic hum of something she couldn't place. "Your sergeant's warrant won't get you past the turnstile either." Quinn looked down the stairwell. The walls curved away into light the colour of amber and dust, and the stone steps descended farther than any Tube line she had ever ridden. Somewhere below, Herrera was already gone, swallowed by the crowd. Behind her, the rain drummed on the plywood and the cab's taillights bled red across the wet road. She thought of Morris, and of the last time she had followed a man into a place she didn't understand. Quinn stepped onto the first stair.
