The canals of Meridian ran black and silent at midnight, and so did Iri's heart.
She rowed a flat-bottomed skiff through the undercity — the tangled mesh of service channels beneath the floating city's grand plazas and merchant squares. Above her, gas lamps painted the hulls of the upper districts in amber light. Below her, the deep water stretched into an abyss where the bones of the city's founders had been scattered a hundred years ago. She counted the docking piers by memory: seventeen to the Moon Canal, then a left at the broken arch where a stone angel had lost its head to some long-ago storm. Her father had taught her these routes when she was nine years old, sitting in the bow of his trader's galleon, handing her the mooring lines and calling her his little harbor-master.
That was before the Gilded Promise went down with thirty-seven souls aboard. Before the salvage hearings. Before Silas Vorento, the salt-trade magnate whose testimony had pinned the wreck on her father's incompetence — a lie wrapped in polish and delivered with a handkerchief pressed to dry eyes. Her father had been found guilty of negligence, stripped of his license, his boats, his name. He died six months later, not from the sea but from the slow drowning of a man who had lost everything that made him who he was.
Iri had spent three years learning the canals that Vorento's men controlled. She knew the patrol schedules, the blind spots, the narrows where a skiff could slip past a guard boat with inches to spare. She knew that Vorento kept a private dock at the city's third tier, accessible only through a locked iron gate that opened onto a submerged tunnel. And she knew, because she had paid a clerk in the Harbormaster's Office a month's wages for the information, that tonight — the third anniversary of the Gilded Promise's sinking — Vorento would take his ceremonial barge through the Processional Canal to lay a wreath on the water. The same water that held her father's name in its cold, indifferent depths.
She tied the skiff to a rusted ladder and climbed.
The third tier was Meridian's jewel. Houseboats the size of manors lined the main canal, their decks draped in silk awnings and strung with paper lanterns. Vorento's estate occupied the entire eastern slip — a three-story vessel of polished mahogany and stained glass, its nameplate reading Salt-King in gilded letters. Iri had seen it up close only once, during the salvage hearings, when she'd stood on the public dock and watched Vorento step from its gangplank in a white suit, smiling at the reporters as if he had just returned from a holiday.
She found the maintenance hatch behind the water-pump housing. The lock was old, the mechanism gummed with salt and disuse. Her father had taught her how to pick a lock the summer she turned twelve — Every trader needs a backup plan, Iri. The sea doesn't care about your keys. The tumblers clicked. The hatch swung inward. She slipped into the hold of Vorento's floating palace.
Belowdecks smelled of damp wood and expensive perfume. She moved through the cargo hold — crates of imported wine, bolts of silk, crates marked with the seal of the Southern Salt Consortium — and found the spiral staircase that led to Vorento's private study. The door was not locked. Arrogance, she thought. Or the confidence of a man who believed the waters beneath his city would always protect him.
She stepped inside. The study was a museum of stolen lives: maritime antiques, maps in gilded frames, a glass case containing the ship's bell of the Gilded Promise. Iri touched the bell. Her father had commissioned it from a foundry in the Southern Isles, had chosen the brass himself. The inscription read FAIR WINDS AND FOLLOWING SEAS. She wanted to scream. She wanted to take the bell and smash the glass case and let the shards cut Vorento's face the way his lies had cut her father's reputation. But that was not why she had come.
She found what she was looking for in the locked drawer of Vorento's desk — a leather-bound ledger, its pages filled with accounts that would never appear in the Harbormaster's official records. Payments to surveyors who had falsified depth readings. Fees to dockworkers who had loosened the Gilded Promise's mooring lines the night it sank. A single line in Vorento's own hand: 37 souls at 500 salt-crowns per soul — reasonable.
The ink was three years old. The numbers had not faded. Neither had Iri.
She heard the footsteps on the deck above. Vorento's voice, deep and warm, speaking to someone — a guest, a bodyguard. She slipped the ledger into her coat, closed the drawer, and retreated to the shadows behind a curtain of maps. The study door opened. Vorento entered alone, carrying a glass of wine. He was older than she remembered — jowls looser, hair thinner — but the eyes were the same: pale blue, the color of winter ice, and just as capable of cutting.
He sat at his desk, took a sip of wine, and opened a drawer. The one she had already picked. He paused. He stared at the empty space where the ledger had been. Then, very slowly, he turned.
"You can come out," he said. "I don't like being watched by shadows."
Iri stepped forward. She had no weapon. She had not come for violence. The ledger was her weapon, and she held it up now, meeting his gaze without flinching. "You sank my father's ship. Thirty-seven people. You paid men to cut the lines and you paid surveyors to call it an accident. I have your own hand admitting it."
Vorento did not reach for a bell or a pistol. He set down his wine glass and folded his hands on the desk. "Your father's name was Darian Marlet. He was a good captain. A terrible businessman. He owed me eighty thousand salt-crowns. He was going to lose everything anyway. I simply accelerated the schedule."
"You killed him."
"I killed his debt. The men who drowned were the cost of doing business in a city that floats on greed." He tilted his head. "You can take that ledger to the Harbormaster. You can take it to the Magistrates' Court. Do you know what will happen? Nothing. Because I own the Harbormaster. I own the magistrates. I own half the canals in this city. All that ledger will do is make me a more cautious man — and you a dead one."
Iri smiled. It was not a warm expression. "I know."
She had known from the start. The ledger was never meant for the courts. It was meant for someone else — someone who had spent three years waiting in the undercity, someone who had lost a daughter on the Gilded Promise, someone who had once commanded a salvage crew and knew exactly where to cut a hull to make it sink fast and silent.
The explosion shook the entire study. Glass shattered. The floor tilted as the Salt-King groaned and listed to port. Water began to pour through the cracks in the hull. Vorento scrambled for his desk drawer, pulling out a pistol, but Iri was already moving — not toward him, but toward the door. She had done what she came to do. She had brought the truth to someone who could use it.
She dove through the hatch into the canal as the Salt-King rolled onto its side, its gilded nameplate sliding beneath the black water. Behind her, the burning wreck of Vorento's empire sank into the deeps she had known since childhood — the same deeps that had swallowed her father, the same deeps that kept no records and answered no questions.
Iri surfaced in the shadow of the Moon Canal. The skiff was waiting. The ledger was still dry inside her coat. She rowed away from the flames and the shouts and the bells of the fire-boats, and she did not look back. Vengeance, she had learned, was not a storm. It was a tide. It moved slow. It moved patient. And when it was time, it took everything in its path.
At the edge of the undercity, where the canals opened into the open lake, a salvage boat waited. The old woman at the helm — gray-haired, sharp-eyed, her daughter's name tattooed on her forearm — extended a hand. Iri took it.
"Your father would be proud," the woman said.
Iri shook her head. "He'd want me to burn the ledger and go home."
"And will you?"
She looked back at Meridian, the floating city of lights and lies, and thought about all the other ledgers still hidden in the dark. "No," she said. "I'm just getting started."
