Questions
How do I solve it?
Read Miss Quill's notes in order. Each one ends in a plain rule. Cross out every line in the ledger that the rule describes. After all 18 notes, one name is left.
Can I check my answer without spoilers?
Yes. Checkpoints tell you how many names should still be standing along the way, and the Verdicts let you check the card number you found.
Is there a practice round?
Yes. A practice case with 60 borrowers walks you through every step before you start the real ledger.
How big is the print?
Every word in the book is printed at 16 point, including the 3,000-line ledger, on 8.5 x 11 inch pages.
