Honestly, it just strikes me as odd that he was able to tell both what was traded and how much it was worth given that the notebook is ciphered. I know nothing about accounting or bookkeeping, so I'm not going to pick at details, but that at least was noticeable.

Nah, thats the point of a summary ledger, to clearly definite what is traded and how much.

The trick is how its organized and calculated. Theres a major difference between single-entry and double-entry accounting, and lets leave it at that. Medieval bookkeeping was a horrendous affair.

EDIT: But to make things simple, lets just have our lord just read the (surprisingly easy to understand) cover summary to the ledger booklet and return to talking with Hana shall we? And why she is [i]really[/i] here.
