No Clue Here
Most of them contain secret information in the 'TOP SECRET" button thing. Most of the time you have to crack a code to find that. Also, the cards lead to clues. if you get a card combo, you may perhaps get a clue. not all 39 card combo's contain clues. you can also get the 39 clues card pack with 16 cards in it.
P23HRFXFXP here is the card to unlock clue 75
In the 39 clues what is the code for card 67?
There is nothing called a code book. The 39 clues cards have codes by which you unlock cards. If you mean Agent Card Code then you can get your agent card code in the agent card option in my cards. My agent card code is P2FHHNDHXP
