“His ledgers are perfect — no heart, no greed, no error, the incorruptible accountant. Except at the year's end, the abacus comes up one coin over: a coin with no source, no destination, no name attached. He has carried the discrepancy for centuries, entered faithfully every year as 'one, unaccounted.' The Two Caishen checked the vaults. The vaults are exact. The coin is not in them.”
Bigan's abacus counts a coin that isn't there.
