Chapter 1: The Old Ledger Surfaces

Tokyo slipped into night, sea fog rolling off the Sumida River and creeping into the escort agency.

I pried open the bottom of the old cabinet Dad left behind and found a Lacquer Box. The lock had long since rusted shut, and inside, there was no gold or silver. Just half a Vermilion Seal. A corner was chipped off, its edges crusted with hardened salt, as if it had been forcibly dug out of some damp, decaying wreck.

I cupped the Vermilion Seal in my palm. The lantern flickered, and the surviving seal carvings looked like the masts of a ship sinking into the tide.

It had been thirty years since my father disappeared. The agency’s ledgers only recorded a single line: "Escort late; passenger and cargo lost." But carved into the back of this Vermilion Seal was the family crest I knew better than my own name.

Footsteps echoed from outside the door.

"Chief Escort Leader, you’re the only one who has the warehouse keys." Sōki Ōnishi kept his voice low. "If you’re digging through old stuff in the middle of the night, you could at least tell me. Otherwise, I’m going to assume we have a break-in."

I slipped the Vermilion Seal away and scanned the threshold. In the dust, there was a single set of muddy footprints. Coming in. No track going out.

"If someone actually broke in, they wouldn’t have put the Lacquer Box back exactly where it was. The one who came tonight wasn’t looking to steal."

Sōki Ōnishi stepped closer, his gaze dropping to my cuffs. He didn’t touch his blade, but his hand rested on the hilt. The river mud on my soles, the swapped-out cloth socks, even the way I deliberately kept my breathing shallow—none of it fooled him.

"So it’s you," he said. "You went out the back, came back, and changed shoes. You’re digging into your father’s old accounts. Why keep me out of the loop?"

I shoved the Lacquer Box into a hidden compartment. Sōki was the Deputy Escort Leader, not a courier for the Sea Transport Guild. The agency guards the cargo in front of us; the Guild’s spies chase down wrecks from thirty years ago. When those two worlds collide, it’s usually the people inside the house who get scrambled first.

"Because you’re the Deputy Escort Leader, not a courier for the Sea Transport Guild."

"I respect you as the Chief Escort Leader, which is why I didn’t report it as you skimming from the cargo vault." His knuckles whitened slightly on the hilt. "But if you’re taking things for the Sea Transport Guild, the whole agency hangs in the balance with you."

I placed the Vermilion Seal on the desk.

"It’s not cargo, and it’s not something I stole. It came from my father’s old cabinet. There are salt stains on the bottom, and dark pine resin in the wooden seams. The wreck was out in the open sea. Not the Sumida River. Not some ordinary merchant ship accident."

Sōki Ōnishi leaned in to look, his brow furrowing tighter and tighter.

"What does half a seal prove? A wave hits the sea, the crate breaks. Don’t just a Vermilion Seal, even a human bone will drift a thousand miles."

"Stop guessing."

I pulled out a fine-bristle brush, lampblack, and warm wine, spreading a sheet of old paper on the desk. I worked the warm wine into the bristles and gently wiped the chipped edge of the seal, peeling back the salt crust. Flecks of vermillion crumbled onto the paper, revealing a razor-thin chisel mark.

"Real seal in the sea, the vermillion turns to powder in the salt. Someone retouched it later, but the fresh cuts show up white."

I stopped, pointing to the missing corner.

"This isn’t a crack from impact. It was chiseled off."

Sōki studied it for a long time. He knew stone and metalwork; he knew the marks weapons left. Finally, he had to admit it: three chisel cuts angling inward. If it were a collision with rock at sea, the edges would splinter outward. The force here was concentrated on the back of the seal. Someone had held it, attacking from the front.

I dusted a thin layer of lampblack over the seal face, pressed paper over it, and lifted it. A line of tiny seal script rose from the black imprint.

This wasn’t a merchant house stamp, and it wasn’t an escort agency mark. The text broke off from left to right. The two missing characters might still be listed in the Port Departure Registry.

Sōki stared at the rubbing. "You want to dig through the Port Departure Registry from thirty years ago based on one printing? Most of the old books have rotted to dust. Even if they survived, they probably won’t let outsiders see them."

"Which is why we need Muneyūrō Fujiwara."

The magistrate’s office had the homicide case files. Muneyūrō was strict about evidence; he wouldn’t change a single character just because someone had money.

Sōki was silent for a moment, but he wasn’t letting me off the hook. He asked where I’d been last night. I said I’d met with the Sea Transport Guild’s manager to retrieve the Lacquer Box, but I didn’t give the man’s name.

Sōki’s eyes went cold. He said he’d protect the people first, then the cargo. But if I kept keeping secrets from him, he didn’t even know which side of me he was supposed to defend.

Just then, the sound of geta sandals echoed from the doorway.

Muneyūrō Fujiwara pushed the door open. He wore a worn black haori, holding a bundle of oilcloth-wrapped, broken ledgers. He looked at me, then at the Vermilion Seal on the desk, his face darker than the fog.

"Koyuki Ōnishi. Someone took a page from the wreck case files today from the magistrate’s old storage."

I asked, "Who?"

"No name. Just a property collection stamp."

He untied the oilcloth. The ledger pages were warped from the damp. The chipped corner of the stamp on the file matched the Vermilion Seal perfectly. The collection time logged was the night before my father disappeared.

Sōki gripped his hilt, demanding to know if someone could tamper with magistrate’s case files. Muneyūrō didn’t answer immediately; he just held the sealing wax up to the lantern.

He’d checked the wax. The seal wasn’t broken, but a page was missing. Someone had re-sealed the file with an old stamp. The technique was sloppy, but enough to fool anyone looking only at the ink color.

I took a copper needle and probed gently along the crack in the wax. The tip caught on something, pulling out a fine thread.

"Two stamps here," I said. "The first one was flat. The second has a drag mark. Whoever took the page didn’t re-seal the file. They cut open the wax and pressed half a seal onto the old mark."

Muneyūrō looked up. "You can tell the direction of the drag?"

"Fresh ink drags a fine thread; dry ink leaves a hard edge."

I handed him the needle tip. The thread angled to the right. That meant the person sealing the file was standing at the edge of the desk, holding the seal in the right hand and pressing the paper with the left. It wasn’t the standard method the magistrate’s office used.

Sōki muttered his assessment: The person knew the files but didn’t know the courthouse’s rules. He could get into the old storage, but he wasn’t a real official.

Muneyūrō pulled a thin sheet of paper from his sleeve.

The wreck case listed the cargo: seventeen crates of raw silk, three crates of gunpowder ingredients, and one sealed Vermilion Seal. But when the stock was entered into the warehouse, there were only sixteen crates of silk. The words for the seal had been blacked out with ink.

I stared at that line of ink, my chest tightening as if an old rope was being pulled tight around it.

My father had never escorted ordinary merchandise. He had been hired by the agency to guard the cargo, but also commissioned by the Sea Transport Guild to track down where the Vermilion Seal belonged. If the sinking of the ship was a front, my father found something on board that he shouldn’t have.

Sōki asked why my father didn’t send word back to the agency. There were relay stations on the route, and contact points. He shouldn’t have been able to disappear without leaving a single character behind.

I pointed to the edge of the broken ledger. There were three overprint seals, and the ink on the third one was clearly different.

My father didn’t send one letter. He sent three. Someone destroyed two of them and deliberately left the third so the next generation would believe his escort failed.

Muneyūrō traced the edge of the paper and asked if I thought my father was still alive.

I didn’t know.

But if my father died on the wreck, no one would have needed to scrub the Port Departure Registry, pull files from the case, or chisel the Vermilion Seal. Someone was afraid not of his death, but of the evidence he left behind.

Sōki suddenly turned his head.

"Someone’s outside the warehouse."

We all extinguished the lanterns.

A shadow flickered outside the paper window, like a heron skimming the eaves in the rain. Sōki opened the back door, his blade slicing a cold line through the darkness. I held the warehouse; Muneyūrō tucked the broken ledger into his robes. The fog swirled in the courtyard, but all that remained was a single trampled, cracked wooden tag.

I picked up the tag and deciphered the charred patterns on the back by the faint light.

"A cargo tag from a trading company."

The tag came from Kiyozūrō Ōnishi’s warehouse. Kiyozūrō was Sōki’s uncle and the agency’s biggest backer. Lately, he’d been obsessed with collecting Antique Seals. If anyone had the capability to pull an old seal out of a wreck and the guts to burn the site, it was him.

Sōki’s face flickered, warning me not to point fingers at his uncle based on one tag.

"I’m not pointing fingers."

I handed the tag to Muneyūrō. The edge had been scorched by fire, but the cracks were still caked with sea salt. It had been removed from a ship’s cargo recently.

Muneyūrō brought it close and sniffed.

"Pine resin, sulfur, sea salt. Not a warehouse fire. Someone was preparing to burn the tidal zone site. Kiyozūrō Ōnishi has been buying large quantities of sulfur and saltpeter lately."

Sōki asked why he would burn the site.

I looked at that half-finished seal face. Masumi Ono had studied Antique Seals and maritime history. She once said that old ship seals were often proofs of ownership for cargo owners and ritual sites. If the site was burned, the wreck’s ownership couldn’t be traced, and the Vermilion Seal could become a private collection piece.

A second set of footsteps sounded from outside the door.

This time, no one was hiding.

Kiyozūrō Ōnishi pushed the door open. He held a blackwood cane and wore no trace of rain on his clothes. He scanned the rubbing paper on the desk, the smile on his face fading inch by inch.

"Koyuki, you inherited your father’s stubbornness, but not his silence."

I closed my hand over the Vermilion Seal.

"You recognize it?"

"I recognize it before the corner was chipped," Kiyozūrō replied. "It chose me, and it chose your father. Your father just refused to admit the seal had a master. That’s what sent the whole ship to the bottom of the sea."

Sōki drew his blade half an inch, forcing him to explain.

Kiyozūrō just stared at me, as if waiting for me to push open that old door myself.

The ship hadn’t been sunk by wind and waves. Someone had altered the ballast stones. My father found out, took the Vermilion Seal, and tried to trade it for the missing escort Manifest. He never realized the Manifest had already ended up in Kiyozūrō’s hands.

Muneyūrō asked coldly why, knowing why the ship sank, he hadn’t reported it for thirty years.

Kiyozūrō leaned on his cane and stepped forward. He said the magistrate’s office only looked at bodies and cargo lists; the escort agency only looked at compensation and reputation. Only the Vermilion Seal could prove that cargo belonged to the ritual site. If the site was returned, dozens of boxes of antiques would no longer belong to him.

I didn’t speak, just stared at his cuffs.

Fresh ash. Damp mud.

Kiyozūrō wasn’t here to talk about old news tonight. He had just come back from the site. The fire had already started.

He was silent for a moment, then laughed.

"Koyuki, you’re finally acting like a Chief Escort Leader. But if you go save the site, you lose the agency. If you protect the agency, you’ll never know where your father hid the Manifest."

Sōki turned to me. The horses in the outer courtyard were already saddled. Muneyūrō could testify, and the wooden tag was in my hand. If we moved now, it might be in time.

I didn’t move.

The half of the Vermilion Seal pressed a cold, hard ridge into my palm. Then, from the missing corner, a drop of wet red seeped out.

Not blood.

I took the copper needle and pried gently at the layer inside the back of the seal. A thin seam cracked open. A slip of paper, thin as a hair, slowly unrolled.

Muneyūrō lowered his voice: "Don’t unfold it. Damp paper, the ink will fade."

But if I didn’t unfold it, the last words my father left would stay sunk at the bottom of the sea.

I held my breath and held the slip to the edge of the lantern’s shadow. The broken ink marks slowly appeared.

"The wreck didn’t sink at sea."

Kiyozūrō’s face finally changed.

I struggled to read the last few characters:

"The ship is in Tokyo; the seal is in Kiyozūrō Ōnishi’s hands. The real culprit will come tonight to retrieve—"

The slip curled up in the heat from the fire outside, the last half-line burning to black ash.

Outside, in the distance, the first bronze gong sounded.

Like someone was ringing the lid of the wreck’s coffin in the fog.
