Chronicle of the solution: The Seal of the Dawn

Poisoning Tier III

The poisoning file is closed. What remains is the part worth learning: how one got from an upturned cup to a name.

The dossier, on a first reading

Something more bitter than gall found its way to the court's table today: poison. The dose was measured with care — enough not to look like chance, too little to go unpunished. Suspicion has fallen on Costache the Toll-Keeper, Abbot Corvus, Ilinca the Baker, Anica the Miller and Chancellor Veniamin — and until the proof is plain, none of these names leaves the room. Motives abound — greed, fear of exposure, jealousy, a debt of honour and blackmail — yet only one moved the guilty hand. The threads were tangled on purpose: investigate, weigh every word, and pronounce your verdict only when the grid leaves no room for doubt.

The circle closed around these names: Costache the Toll-Keeper, Abbot Corvus, Ilinca the Baker, Anica the Miller and Chancellor Veniamin. The investigation was not permitted to step outside it, and had no need to.

The testimonies on file

The list below is complete and pared to the bone. The Chancellery keeps no useless rows on file: each cuts something no other cuts.

  1. The tracks in the dust do not lie: Costache the Toll-Keeper was there at dusk.
  2. A maid whispered it at confession: the signet ring and blackmail go together.
  3. Before the investigator, Chancellor Veniamin firmly repeats: "I handled the ruby dagger".
  4. The chancellor deduced it coldly: if Ilinca the Baker was at the wharf, then Anica the Miller handled the ruby dagger.
  5. An honest-faced witness saw it plainly: Abbot Corvus was driven by jealousy.
  6. The tracks in the dust do not lie: Abbot Corvus was at the salt market.
  7. The tracks in the dust do not lie: the customs scales matches that hour: after matins.
  8. The gate guard swears: a debt of honour matches that hour: at dawn.
  9. The chronicler notes drily: Chancellor Veniamin was driven by fear of exposure, whatever the court may say.
  10. An honest-faced witness saw it plainly: the herald's horn matches that hour: at dusk.
  11. The chronicler notes drily: the mill by the river and the customs scales go together, whatever the court may say.
  12. In the gate ledger, the suspect with grey hair stands higher, Abbot Corvus lower.
  13. The chronicler notes drily: the suspect with blond hair was at the old chapel, whatever the court may say.
  14. An honest-faced witness saw it plainly: the merchant's house and greed go together.

How it was unravelled

No suspicion weighed here. Only the grid weighed: every certain match sweeps a whole row and a whole column, and at the end one arrangement alone remains possible.

The scouts brought their share as well: “The tracks in the dust do not lie: Costache the Toll-Keeper was there at dusk”. A pair was tied, and the knot dragged a whole handful of impossibilities after it.

A detail overlooked at the start came back into the file: “A maid whispered it at confession: the signet ring and blackmail go together”. A certain match thus enters the grid, and its row and column empty at once of every other possibility.

The gate register had kept a trace of its own: “Before the investigator, Chancellor Veniamin firmly repeats: "I handled the ruby dagger"”. The testimony entered the file with a reservation attached: true if the speaker is innocent, false otherwise.

The archivist copied on, without comment, everything that could be proved: “The chancellor deduced it coldly: if Ilinca the Baker was at the wharf, then Anica the Miller handled the ruby dagger”; “An honest-faced witness saw it plainly: Abbot Corvus was driven by jealousy”; “The tracks in the dust do not lie: Abbot Corvus was at the salt market”; “The tracks in the dust do not lie: the customs scales matches that hour: after matins”; “The gate guard swears: a debt of honour matches that hour: at dawn”; “The chronicler notes drily: Chancellor Veniamin was driven by fear of exposure, whatever the court may say”; “An honest-faced witness saw it plainly: the herald's horn matches that hour: at dusk”; “The chronicler notes drily: the mill by the river and the customs scales go together, whatever the court may say”; “In the gate ledger, the suspect with grey hair stands higher, Abbot Corvus lower”. Taken one at a time they seemed slight; laid together in the grid, they left one arrangement alone possible.

A witness of good faith cleared up one more corner: “The chronicler notes drily: the suspect with blond hair was at the old chapel, whatever the court may say”. Once the tick was placed, the investigation had nothing left to argue on that row and moved on.

A piece of information dearly bought showed its worth: “An honest-faced witness saw it plainly: the merchant's house and greed go together”. The match was nailed down, and the rest of the row was left clean, like a page wiped with a sponge.

The lying testimony

The Chancellery caught the mismatch on its first reading of the grid. Chancellor Veniamin swore before the Chancellery that I handled the ruby dagger, when in fact Chancellor Veniamin never touched the ruby dagger. The innocent have no cause to lie; under the Supreme Law, whoever does points at themselves.

The culprit's name

The name the grid could no longer force out of the circle is Chancellor Veniamin. The arrangement in the grid is this: Chancellor Veniamin was at the mill by the river, handled the customs scales, was driven by fear of exposure and was there after matins. Tier III is no empty word: without the method of hypotheses, this grid would not have closed.

Those taken out of the circle

The Chancellery recorded the others' movements as well, because it was precisely they that closed the grid: Costache the Toll-Keeper was at the merchant's house, handled the herald's horn, was driven by greed and was there at dusk; Abbot Corvus was at the salt market, handled the ciphered letter, was driven by jealousy and was there at vespers; Ilinca the Baker was at the wharf, handled the signet ring, was driven by blackmail and was there at noon; Anica the Miller was at the old chapel, handled the ruby dagger, was driven by a debt of honour and was there at dawn. Not one of the rows above is spare — remove it and the grid opens again.

The truth did not surface in a flash of insight but out of a run of small cuts, every one of them checkable.
