Brother Matthias first heard the choir during the elevation of the host. Its note rose through the cathedral floor, too low for any living throat, and made dust leap from the saints carved above the altar. The bishop called it settling stone. By midnight the note had become harmony. By dawn every candle in the nave bent its flame toward the sealed crypt, and the bishop ordered Matthias below with a hammer, a censer, and instructions to silence whatever blasphemy he found.
The crypt stairs ended at a wall newer than the foundations. Behind it, the choir sang without words, yet Matthias understood every name. Agnes Vale. Tomas Reed. Infant, unnamed. Forty-seven voices, then eighty, then hundreds. He broke one brick and a finger bone slid through the gap. The mortar smelled not of lime but of old incense. In the bishop's archive he found the missing plague ledger and a payment signed by Bishop Corven's ancestor: masons' wages for sealing the fevered poor below while they still breathed.
Matthias spent the afternoon carrying fragments of the truth through the city. An old seamstress recognized Agnes Vale as the woman whose house had become the bishop's summer residence. A cooper showed him a family charm bearing Tomas Reed's initials. At the orphan hospice, a nurse wept over the unnamed infants and supplied the names their mothers had whispered before dying. The dead had not been forgotten by accident. Their lives had been cut apart and distributed among respectable families who preferred not to see the seams.
When Matthias returned, the singing had become strong enough to shake flakes of gold from the altar. He crawled through the opening and found the skeletons seated shoulder to shoulder, many with broken fingers from clawing the stone. One small skull rested in an adult's lap. Matthias promised to open the wall, but the choir refused his promise with a single dissonant note. Release without witness would only create another secret. They wanted their names spoken where the lie had been blessed.
The bishop came before sunset with armed vergers. “The city survived,” he said. “History is merely the wall we build around necessity.” He commanded Matthias to fill the breach. Instead, Matthias carried the ledger to the pulpit and began reading. The choir answered each name. Citizens crowded the nave as the floor shook, and hairline fractures ran from the altar to the western doors. The bishop seized the book, but the bones below had reached the final entry: Corven, Elias—physician, witness, murdered.
The bishop's own name followed. Not as victim, but as inheritor. The crypt wall burst outward. Skeletons remained seated in ordered rows, jaws lifted in song. They did not rise. They did not attack. They merely sang until the bishop confessed that his family had preserved the lie and profited from the dead men's homes. When he finished, the bones lowered their heads. Matthias opened the cathedral doors so the whole city could hear the silence that came after.
They buried every victim beneath a stone bearing a name. The cathedral lost its bishop and gained a new ritual: once each winter, the plague ledger was read aloud from first page to last. Matthias grew old keeping the names. On the night before his death, a novice found him asleep beside the crypt and heard one soft new voice join the choir. It sang Matthias only once—not in accusation, but in welcome—and then the bones were quiet forever.
