The workshop smelled of cedar wood, camellia oil, and the faint, metallic tang of polished brass. In the bustling Nihonbashi district of Edo, where merchants shouted their wares and the clatter of wooden geta sandals on cobblestones created a ceaseless urban symphony, Kenjiro’s shop was a sanctuary of measured time. It was the eighth year of the Kyōhō era, a time of relative peace under the Tokugawa shogunate, and Kenjiro had embraced it fully. He sat cross-legged at his low wooden bench, a loupe squeezed into his right eye, his large, calloused hands working with impossible delicacy to place a hairspring into a traditional wadokei—a Japanese lantern clock.
He was a man of forty, though the deep lines etched around his eyes and the stark white streaks in his dark hair made him look older. Once, those hands had wielded a katana with terrifying proficiency in the service of the Asano clan. But the clan was dissolved, the lord disgraced, and the samurai had been cast to the winds as ronin. Kenjiro had chosen to lay down death and take up the creation of time.
“Master,” a bright voice interrupted the rhythmic ticking of the room. Mariko, his fourteen-year-old apprentice, slid the paper shoji door open. She held a tray with a steaming ceramic teapot and two small cups. “You have been hunched over that escapement gear since the morning bell. Your eyes will fail you before you reach fifty.”
Kenjiro sighed, carefully setting down his iron tweezers. He removed the loupe and offered the girl a faint, appreciative smile. Mariko was an orphan he had found wandering the docks three years ago. She possessed a sharp, inquisitive mind, entirely unsuited for the traditional roles expected of a young woman in Edo, but perfectly suited for the intricate mathematics of horology.
“Time waits for no man, Mariko,” Kenjiro replied, accepting a cup of green tea. The bitter, earthy warmth was a welcome comfort against the damp chill of the autumn afternoon. “And the silk merchant on the corner expects his clock to chime perfectly by tomorrow evening.”
“The silk merchant only wants to boast to his rivals,” Mariko mumbled, sitting on a straw tatami mat across from him. “He doesn’t care about the craftsmanship.”
Before Kenjiro could impart a lesson on patience, the peace of their shop was violently shattered. The wooden front door burst open, crashing against the wall. A gust of cold, rain-scented wind swept into the room, extinguishing the oil lamps.
A man staggered over the threshold, clutching his stomach. He wore the dark, unobtrusive garb of a courier, but the fabric was saturated with a terrible, dark wetness. He collapsed onto the wooden floorboards, knocking over a pedestal holding a half-finished water clock.
Kenjiro was beside him in a fraction of a second, moving with a fluid, explosive speed that shocked Mariko. The clockmaker knelt, pressing his hands against the man’s abdomen to stem the bleeding, but it was a fatal wound. The cut was deep, precise, and upward—the unmistakable signature of a master swordsman.
“Help him, Master!” Mariko cried, hovering anxiously, her hands fluttering helplessly.
“It is too late,” Kenjiro said softly, his voice devoid of panic, replaced by a chilling, practiced calm. He looked into the dying man’s eyes. “Who did this to you?”
The courier coughed, a spray of crimson hitting the polished cedar floor. With trembling, blood-slicked fingers, he reached into his tunic and produced a heavy object wrapped in oilcloth. He shoved it toward Kenjiro.
“The spider…” the man gasped, his breath rattling in his throat. “Lord Ishida… he hunts the iron birds. The map… it is in the time…”
The man’s eyes rolled back, his body seizing once before going entirely limp. The silence that followed was deafening, broken only by the steady, indifferent ticking of the dozens of clocks lining the workshop walls.
Kenjiro stood slowly. The blood on his hands felt like a ghost from a past he had tried desperately to bury. He looked down at the oilcloth bundle. Carefully, he peeled back the fabric to reveal a clock. But it was not a wadokei. It was a Western device, a Dutch table clock encased in tarnished silver, adorned with complex astronomical dials that tracked the phases of the moon and the alignment of the stars. It was heavy, beautifully crafted, and currently utterly silent. The glass face was cracked, and the hands were frozen at an impossible angle.
“What did he mean, Master?” Mariko whispered, staring at the corpse. “Lord Ishida? He is the daimyo of the northern province. A powerful man. A cruel man.”
“A man who has no business operating in the shadows of Nihonbashi,” Kenjiro muttered, examining the silver clock. There were no visible screws, no obvious way to open the casing. It was entirely sealed.
Suddenly, heavy, synchronized footsteps echoed from the cobblestone street outside. The sound of drawn steel hissed through the damp air. Men were shouting, demanding to know where the bleeding courier had gone.
Kenjiro’s eyes hardened. The peaceful years evaporated in an instant, replaced by the cold calculus of survival. He turned to his apprentice.
“Mariko, grab your traveling cloak and the bag of silver coins beneath the floorboards in the kitchen. We are leaving. Now.”
“But the shop—”
“The shop is wood and paper,” Kenjiro said, his tone leaving no room for argument. He shoved the Dutch clock into a deep pocket in his kimono and wiped the courier’s blood from his hands onto a rag. “If Ishida’s hounds find us with this man and this device, we are dead.”
They slipped out the back exit just as the front shoji screens were violently slashed open by the blades of Lord Ishida’s retainers, plunging Kenjiro back into a world of violence he thought he had left behind forever.
