Hints by Clue
Clue 1
Find the witness date in the ledger first. Use its ledger page number to decide whether the answer is on an odd or even page.
Clue 2
The day number of the final date is not prime. It can be divided exactly by a smaller number other than 1.
Clue 3
Look up the witness date and check the number in its map code. The final answer has the same odd-or-even property.
Clue 4
For the witness date, check whether the first and last letters of its ledger word are consonants or vowels. The answer follows the same pattern.
Clue 5
Compare the answer’s map code with the map codes directly above and below it in the ledger. The true code must be different from both neighbours.
Clue 6
Check the ledger words immediately above and below each candidate. At least one neighbouring word must contain a repeated letter.
Clue 7
Look up the witness date and count the vowels in its ledger word. The final ledger word has the same number of vowels.
Clue 8
Compare the first and last letters of the ledger word. The first letter must come earlier in the alphabet.
Clue 9
Find the witness date and note whether its row position within the printed column is odd or even. The answer matches that row parity.
Clue 10
Compare the ledger word with the month name alphabetically. The ledger word must come first.
Clue 11
Look at the ledger word above and the ledger word below. The upper word must come before the lower word alphabetically.
Clue 12
Use the witness date to learn the neighbour-length pattern. The answer’s neighbouring words must follow the same shorter-to-longer or longer-to-shorter pattern.
Clue 13
The final ledger word contains at least one repeated letter.
Clue 14
Compare the map-code number with the month number. The map-code number must be larger.
Clue 15
Compare the length of the ledger word with the length of the month name. The ledger word must be shorter.
Clue 16
Compare the map-code letter with the first letter of the month. The map-code letter must come earlier alphabetically.
Clue 17
Find the witness date and note which printed column it appears in. The answer is in the same column.
Clue 18
Look outside the pages of the book!
