On the fifth day after the Lamp Oil case was opened, opportunity came knocking of its own accord.
A lamplighter died.
The Stillwater Society reported the death first. At dawn, a municipal sweeper found the body at the eastern foot of the Dawn Tower. The dead man was Otto Brandt, forty-one, a Stairclimber of the tower with twenty-three years of service.
The Church of the Daystar's notice ran to one sentence: Brother Brandt regrettably fell from the tower while on duty. The church expresses its profound sorrow.
By custom, the secular authorities had no right to inquire into the death of anyone serving on holy ground. This time, however, the church had opened its own door a crack—because when the dead man fell, his hand was clenched around something it should not have held.
A page of paper. He gripped it so fiercely that his finger bones could not be straightened. The soul-ferryman from the Stillwater Society had worked with the rigor, prying it loose one finger at a time.
The page bore no ink, only indentations—indentations abandoned by their words. Three lines.
The Stillwater Society knew such paper. In the Lower City case, they had ferried too many waxen mouths. Rather than return the sheet to the church, the ferryman in blue-green robes delivered it to the Vesper Bureau that same night. A single sentence was enclosed on a water-green slip:
The river has grown crowded of late.
"The church is trapped now," Grey said, laying out the situation at the case conference. "The dead man held a page of 'faded-ink paper.' The moment that appears, the case changes from 'ecclesiastical affairs' to a 'supernatural incident.' Under the Vesper Accord signed three hundred years ago, the Vesper Bureau has the right to inspect supernatural incidents, holy ground included. The church can delay us and make difficulties, but it cannot refuse. All it can do is limit the scale—"
He raised two fingers.
"Two people. The church will admit only two Duskwardens, accompanied throughout by the tower warden, and they must leave before sunset. They even named one of them."
A cold smile touched the old inspector's mouth. "They specifically requested 'the consultant who took the stage on the premiere night at the Golden Iris.'"
The conference room fell silent.
"They asked for me?" Sharlo frowned. "In the church archive I'm a 'person of unknown provenance.' They can't avoid me fast enough."
"Which is why this case has smelled wrong since it entered the door," Grey said. "Either someone inside the church wants you to see something, or someone wants 'something' to see you. Neither is good. Either way, you go. Raven is the second."
He raised a hand to stop the medical officer's objection before it emerged. "There are no beds in the tower; sleep is not involved. Besides, ninety-nine of every hundred useful eyes among my people are useless there. You'll soon see why."
* * *
The Dawn Tower was taller than anyone who had looked up at it from the city could imagine.
It rose from a bedrock foundation in the eastern quarter. Its stone was a warm grey-white, without a single carving. Only a band of windows spiralled upward, circling the tower seventy-two times like a screw thread.
From the foot of the tower, its summit vanished into the morning fog. It was invisible even on cloudless days, people said, forever bleeding into some fine halo of light.
The tower warden waited before the door.
The old man introduced himself as Selden and said he had served in the tower for fifty-one years. He was tall and thin, with a pronounced stoop—an odd stoop, not a hunch, but the posture of a bow kept strung for years, his whole body inclined slightly toward the tower as though he were climbing even when he stood on level ground. His hands were broad and rough, the calluses across his palms joined into an unbroken shell.
"Vesper Bureau." Selden inspected their documents, his clouded eyes resting briefly on Sharlo's face. "Three rules inside. Do not touch the lamps. Do not ask names. Leave before sunset."
"Do not ask names?" Viola said.
"People inside the tower have no names." Selden turned and pushed open the door. "Past this threshold, you are Stairclimber, he is Stairclimber, and the man who died was Stairclimber. Leave names outside. Names are too heavy. Carry one, and you cannot climb ten thousand steps."
The instant the tower door closed behind them, Sharlo understood what Grey had meant about ninety-nine of every hundred useful eyes.
There were no lamps inside, yet the tower was bright as day.
Light streamed down the inner wall. From its unseen summit to the flagstones beneath their feet, the whole interior was covered in flowing, honey-coloured radiance, as though the stone itself had burned slowly for a thousand years and become translucent. The light did not dazzle, but it was full—so full that not a shred of shadow could find a place within it, so full that—
Instinctively, Sharlo looked above Selden's head.
Nothing.
Not the absence of a fate-line. He simply could not see it. Where amber writing ought to have hung above the old tower warden was a torrent of honey-coloured light.
Any words that entered it would be snow falling into a furnace. He looked at Viola. The same.
He could read nothing. For the first time in three months, Sharlo's eyes had become the eyes of an ordinary man.
Viola drew the faintest breath beside him. Her eyes, which saw the flicker of lies, were no different; in this light, they could filter nothing.
"There are no dark places in the tower," Selden said without looking back, as if he had eyes behind him. "So there is no such thing as 'seeing through' here. Duskwardens, all the tricks you perform with your eyes go blind past this door. The tower recognises only one thing—"
He raised his callus-shelled hands and patted the first step beneath his feet.
You could be reading stolen content. Head to Royal Road for the genuine story.
"Legs. Come. The place where it happened is at Step Four Thousand Three Hundred."
Four thousand three hundred steps took five hours.
The stair wound along the inner wall, with honey-flowing stone on one side and the vast hollow of the tower on the other. Above the thousandth step, Sharlo finally understood the interior's structure. The Dawn Tower was hollow. Something hung at its centre, descending from an invisible height to an invisible depth—
A wick.
No other word could describe it. A gigantic wick as thick as a man's embrace turned slowly in the hollow, silver-grey strands of light and dark twisted together like a cable spun from a billion filaments. It did not burn—the burning took place at the summit—but it was alive.
The immense wick pulsed faintly in a rhythm almost like breathing. Tiny points of light moved upward along the twist of its fibres, like a river of stars flowing against its current.
"The sunwick." Selden did not look back. "You may look. Do not point. Pointing at a lamp is disrespectful."
Sharlo withdrew his finger. He tried counting the rising lights, then gave up. There were too many, dense as moths on a spring night, ascending without end from the darkness beneath the tower toward the halo at its summit.
"These lights... what are they?"
"Oil," Selden said.
"Where does the oil come from?"
The old tower warden's stride faltered by a fraction of a beat.
"Below," he said. Then he quickened his pace, using his back to end the subject.
At Step Two Thousand Eight Hundred, the stair passed through a circular hall.
Names covered the inner wall, ring upon ascending ring, following the tower's spiral. The ages of the inscriptions ran from deep to shallow. The oldest had been steeped so long in the tower's light that their edges were smooth as stones in a stream. The newest still exposed raw stone within its cuts.
"The Hall of Names." Selden slowed here, and his voice softened as if he had entered his family's ancestral shrine. "A Stairclimber surrenders his name upon entering the tower. While he lives, he has no name inside. When his 'oil runs dry'—" The old man lifted his callused fingers and brushed them lightly over the rings of inscriptions.
"The tower gives his name back and carves it here. His family may not remember him, but the tower does."
"His family does not remember?" Viola asked.
"The contract they sign when he enters," Selden said. "A Stairclimber's dependants receive double compensation. The price is... fading memory. They don't forget everything. At the holidays, they remember that 'someone in the family serves in the tower,' like remembering an entry in a ledger. But they cannot recall his face or voice. The church calls it mercy. No one who enters the tower returns. Better that a family hurt for six months than suffer for a lifetime."
Sharlo followed the newest ring of inscriptions. At its end, he stopped.
Otto Brandt. The cuts were painfully fresh, the raw edges not yet softened by the light. Beyond the name ran a long row of name-niches already chiselled but still empty—compartment after compartment, like seats prepared in advance by the Hall of Names.
He counted. Forty empty niches.
"Warden," he asked softly, "are these empty niches customary?"
Selden followed his gaze. Inch by inch, the old man's face darkened beneath the honey-coloured light.
"No," he said. "A name-niche is not cut until a man is gone. These forty... three months ago, the church sent masons down to carve them in one night."
The old tower warden stared at the empty spaces, his throat moving, his voice dry enough to crack. "I asked why. The answer from above was: reserves."
Forty empty name-niches, carved in advance, waited soundlessly in the wall.
None of the three spoke again. From that place upward, there was only the sound of footsteps and the hum of the sunwick.
They passed three shifts of Stairclimbers on the way. All were silent men with broad palms and bowed backs, each body curved toward the tower. Every shift carried cargo. Not barrels of lamp oil—Sharlo looked deliberately—but wooden cases shaped like bellows, borne between pairs.
The cases resonated faintly with the pulsing sunwick and hummed as they passed. The Stairclimbers neither looked at nor greeted the visitors. They merely pressed themselves toward the stone wall to give way, moving with the precision of one body.
Only a young man followed at the rear of the last shift. He was eighteen or nineteen, not yet stooped, the bow of his back barely beginning to draw. As he passed Sharlo, he committed what was plainly a forbidden error inside the tower: he looked at them.
Only once. His gaze passed over the black coats of the Duskwardens, over the badge at Viola's collar, and settled on Sharlo's face for half a beat. It contained neither hostility nor curiosity. Sharlo had seen such a look before, in Mick's eyes outside the boiler works: the look of a young man with a bellyful of words and rules welded over his mouth, searching a crowd for someone to whom he could speak.
"Cole," Selden said without turning, his voice quiet. "Eyes."
The young man lowered his gaze at once and followed his shift into the spiral above.
At Step Three Thousand Nine Hundred came the customary rest. A small alcove had been cut beside the stair, containing a stone bench and a communal water jar. As Selden sat, Sharlo spoke with apparent idleness.
"That young man just now. Warden, you called him 'Cole.' I thought names were not used in the tower."
The old man's hand paused around the water jar.
"... I broke the rule," he admitted without evasion. "Habit. The boy entered the tower four years ago. Brandt brought him in—an orphan from the south of the city, sleeping in the tower doorway in winter. Brandt found him after a night shift and fed him hot porridge, bowl after bowl, until spring. In the end, he simply put down his thumbprint as guarantor and brought the boy into the tower."
"By tower rules, guarantor and apprentice serve the same shift. For four years, Brandt taught him every skill he possessed: how to read the wick, how to listen to the lamp, how to husband one's legs across ten thousand steps." Selden drank, and his voice lowered.
"The morning Brandt died, Cole was the first to refuse belief. The boy knelt at the tower foot for half the day and repeated one sentence over and over: 'Uncle's legs—my master's legs—never set one foot wrong in twenty-three years.'"
"Do you believe it, Warden?" Viola asked. "Would legs that had not missed one step in twenty-three years fall from a maintenance platform he could cross with his eyes closed?"
Selden did not answer. He returned the water jar to the alcove, set it straight, and rose. With the silent back of a Stairclimber of fifty-one years, he led them onward.
Sharlo fell half a pace behind and exchanged a look with Viola. Both had noticed the same thing. When she said "he could cross with his eyes closed," the hand on Selden's knee had clenched for an instant—not the clenching of grief.
The clenching of a man who knew something and swallowed it.
* * *
The place of the incident was at Step Four Thousand Three Hundred, on a maintenance platform projecting into the hollow of the tower.
Its stone rail stood waist-high and unbroken. The platform was dry, with no sign of a struggle and no scuff left by resistance. Viola examined the floor closely for a quarter of an hour, then rose and gave Sharlo the slightest shake of her head. The scene was clean as if washed by fog.
"Brandt served the night shift here for eleven years," Selden said from the entrance to the platform. "A place he couldn't fall from with his eyes closed."
"Do you consider it an accident?" Viola asked.
"The church notice calls it an accident." The old man answered a different question.
"And you?"
Selden looked out from the platform without speaking. In the tower's hollow, the sunwick revolved slowly and a billion points of light streamed upward. The honey-coloured radiance illuminated every furrow in the old man's face, and illuminated just as clearly the thing that flashed through his clouded eyes—
Grief. Grief held down for too many days until cracks had formed.
"Duskwardens." He spoke abruptly, his voice almost disappearing into the hum of the sunwick. "I have served in this tower for fifty-one years. For the first forty-nine, everyone who died inside died when their 'oil ran dry.' That is how a Stairclimber's life is spent. We know it the day we enter. There is nothing to investigate. But Brandt was different. The night before he died, he came to see me."
He drew a hand from his sleeve. Something small lay across his open palm.
"He asked me one question. The next day he fell. A page whose writing had vanished was clenched in his hand. I do not know what was written on it. But I cannot forget one word of what he asked me."
Selden raised his head and repeated the question to the two Duskwardens, word by word.
"He asked: Warden, I counted while changing the wick last night. Why does this new shipment contain so much more wick-fibre than the oil-vault ledger records?"
In his open palm, the small object showed a colour in the honeyed light that Sharlo knew, a colour that froze the blood.
A strand of grey ash-wick.
The same grey as the ash-wick in the Golden Iris chandelier, the fuse in the candle vault, and the ash candle swallowed by Sweet Voice.
