The Widow's Ledger

When old Margit Hallow dies, she leaves her three daughters not a will but a ledger: forty years of double-entry bookkeeping in which every kindness, insult, loan, and Christmas absence has been assigned a monetary value, with a running balance per child. The estate lawyer, who witnessed and co-signed it, says it is binding — the farm goes to whoever ends in the black.

1. The daughters realize the ledger is still open at the moment of death, which means the accounts can theoretically be settled — so they begin paying each other off in the currencies their mother recognized: Vera drives eleven hours to sit at a stranger's hospital bed because 'visiting the sick, unasked' was worth 400 crowns an entry, and Ilse starts logging her own good deeds in her mother's handwriting.
2. The forgeries force an authentication, and the handwriting expert finds three distinct hands in the ledger going back decades — the mother's, and two others. The youngest daughter, Bo, who left home at seventeen and was never mentioned, has been writing entries since 1994; the third hand belongs to the estate lawyer, who has been quietly crediting himself for 'errands' since the mother's first stroke.
3. To void the lawyer's entries the sisters must prove the ledger was never a legal document — but every argument that destroys it also destroys their own claims, so instead they audit him, line by line, and discover he wasn't stealing: he was zeroing out the mother's debts to a man named Pál, an entry called 'the barn, 1971,' carried forward for fifty years at compounding interest.
4. Pál's grandson arrives with the other half of the ledger — the credit side — and a barn fire report in which Margit's name is the one erased.

💡 The engine is a moral accounting system taken literally: once love is denominated, every character must either pay, forge, or audit — and each of those moves generates the next dispute.
