The heavy slam of a car door echoed through the wet alley outside, sharp as a gunshot.
Julian didn't hesitate. Ten years of calculated routine melted away, replaced by the instinctual reflex of a man who spent his life measuring seconds. He grabbed the velvet-lined lid, snapped the brass-bound box shut, and wrapped the oilcloth tightly around it.
The low hum vanished instantly, smothered beneath the heavy oak and cloth.
"The back door leads to the alley behind the apothecary," Julian whispered, snatching a leather shoulder satchel from a hook beneath his workbench. He swept Clara’s leather notebook inside, along with a roll of precision screwdrivers and his finest brass tweezers. "If they’re smart—and if they tracked you here, they are—they’ve already posted someone at the front."
"Julian," Clara said, her voice tight as she glanced at the front glass window. Shadows moved through the curtain of rain outside. "The front latch."
The heavy brass deadbolt on the shop door gave a sharp, metallic shudder. Someone outside was picking the lock with systematic, professional speed.
"Move," Julian gritted out.
He grabbed Clara’s elbow and pulled her through the narrow archway into the rear restoration room. The back of the shop was a maze of tall wooden shelving, stacked high with disassembled clock frames, oak housings, and rows of glass jars filled with solvent and spare gears.
Julian reached the heavy oak back door, unlocked the deadbolt, and eased it open an inch. The alley was dark, slick with rainwater reflecting the distant amber streetlights. A solitary figure in a dark rain slicker stood near the mouth of the lane, leaning against a brick wall with an umbrella, eyes scanning the street.
"Blockade," Clara murmured, peering over his shoulder. "We can't outrun them in the open."
"We don't outrun them," Julian said, his mind clicking through options like teeth on an escapement gear. "We create an imbalance."
He turned back toward his workbench shelves. Grabbing two large glass jars of high-viscosity clock oil and a heavy brass weight from an old Cuckoo clock, he handed the weight to Clara.
"When I open the front archway curtain, throw that through the display case window," Julian instructed. "Make them think we broke out the front."
Before Clara could answer, a soft click-clack rang out from the front door as the lock yielded. The door swung open, and the brass bell chimed its sweet, cheerful greeting into the dark room.
Now.
Julian unscrewed the jars and poured the slick oil across the hardwood floor just inside the restoration room archway, then pulled Clara back toward the alley door. Clara hurled the heavy brass weight with all her strength through the front glass counter.
The glass shattered with a deafening crash, echoing out onto the main street.
"They're breaking out!" a voice shouted from the front shop. Heavy, disciplined boots charged through the dark toward the sound—and straight onto the oiled hardwood.
A muffled curse and a heavy crash sounded as the lead pursuer lost his footing, skidding violently into a tower of stacked grandfather clock cases. The wooden housings collapsed in a domino cascade of splintering oak and ringing iron gongs.
"Go!" Julian barked.
He threw open the back door. Clara bolted into the rain-drenched alley ahead of him. The lookout at the end of the lane whipped his head around at the noise, dropping his umbrella and reaching into his jacket.
Julian reached into his satchel, pulled out a heavy steel clock-winding crank, and hurled it with the practiced precision of a man who spent eight hours a day hitting millimeter-wide targets.
The steel crank struck the lookout squarely in the chest. The man stumbled back against the brick wall, gasping for breath. Clara surged past him into the main avenue, Julian half a step behind her, their footfalls splashing through the puddles as the rain poured down in sheets.
They rounded the corner onto the avenue just as the engine of the dark SUV roared to life behind them.
"Where to?" Clara gasped, her coat soaked through, her chest heaving as they sprinted toward the neon-lit maze of the city market.
Julian gripped his satchel tighter against his ribs, feeling the solid weight of the brass box through the leather.
"The train station," Julian said. "If this mechanism is a key, we need to find out what it unlocks before they figure out we aren't running—we're hunting."
