The brougham slewed into a Southwark alley so narrow the wheels scraped brick on both sides. Reg kicked the door open before the horses stopped. Isabella stumbled after him, her movements lagging by exactly two seconds ghostly afterimages trailing every step. The stolen shadow had left her hollow-eyed and furious.
"Third door on the left," she panted. "Knock twice, then once. Name's Jem. He owes me."
Reg hammered the signal. The door cracked. A one-eyed man with a scar like a clock hand across his cheek peered out, then yanked them inside. The room was a cellar pocket beneath a gin den stone walls, no windows, no clocks. A single candle burned in a tin dish. Perfect silence.
Jem barred the door with an iron rod. "You brought the Church's favourite bitch and her new pet thief? Bold."
Isabella ignored the insult. "Hide us till dawn. Double the usual."
Jem's single eye flicked to the glowing gear in Reg's fist. "That the thing making bells run backwards? Whole rookery's whispering. They say the Thames is bleeding brass."
Reg set the gear on the rickety table. It spun lazily, veins pulsing. "It lets you steal time instead of bleeding it. No debt. No God noticing until now."
Isabella dropped onto a stool, still two seconds late. "Teach me. Right now. Before the next patrol finds us."
Reg hesitated. Teaching meant trust. Trust meant risk. But her shadow was already gone, and the Church would drain them both for sport. He placed his hand over hers on the gear.
"Feel it first," he said. "Not the metal the hunger. Push your mind into the stolen seconds still warm in your blood. Imagine reaching out and hooking someone else's thread. Not bleeding. Taking whole."
Isabella closed her eyes. The gear flared brighter. Reg felt the pull reverse her trying to sip from him. He let a single second slide across, just enough to show her.
She gasped. Her afterimages vanished for one heartbeat. "It worked. I took it. I feel… full."
Jem snorted from the corner, sharpening a knife. "Cute trick. But the little mute on the bridge already marked you. Little Thread don't mark for fun. She collects debts the Clock-God can't."
Reg ignored him. "Again. Harder. Picture your uncle's last breath. Hook it back from wherever it went."
Isabella's face twisted with effort. The candle flame stretched sideways. Reg felt another second leave his veins—clean, weightless. Her shadow flickered back into place for three full seconds, then tore away again, screaming silently as it flew through the stone wall.
Isabella's eyes snapped open. "It's not just mine. The gear's pulling from everyone we've ever touched. My father. My tutors. Even the footmen outside your shop. It's a chain."
Reg's stomach dropped. He hadn't known. He had thought the theft was clean. "That's the twist nobody tells you. Every second you steal links to someone else's ledger. The Clock-God doesn't miss links. It just waits."
Jem laughed once, low and ugly. "Told you. Little Thread collects." He stepped forward, knife glinting. "And she paid me to deliver you both tonight."
The candle snuffed out.
Darkness swallowed the room. When the flame relit by itself the door was open. Jem was gone. In his place stood Little Thread, barefoot on the stone, broken pocket watch ticking in her palm. Isabella's stolen shadow writhed inside the glass like smoke.
"You thought a room without clocks was safe," the child whispered, voice rust on iron. "There are no safe rooms when the veins are splitting."
She raised the watch. The gear on the table screamed metal twisting, veins bursting open like capillaries. Raw time poured out in black threads, wrapping Reg and Isabella together. Their pulses synced. Their stolen seconds merged into one shared pool.
Reg felt it then: the true horror. He wasn't just a thief. He was becoming the leak. Every second he took now bled straight into the Unseen Clock's heart.
Little Thread smiled. "The Bishop knows. He's coming for the pair of you. But first—"
She flicked her wrist.
The shared time-thread snapped taut.
Isabella's eyes widened in perfect horror as the first real vein of the Clock-God burst through the cellar floor brass and blood and screaming centuries coiling around her ankle like a living noose.
Reg lunged for the gear, but it was already too late.
The Unseen Clock had found its first two anchors.
And it was hungry.
