Centennial House Mystery 

You have now uncovered the word "Books." Your next step is to search around the house for four books that match the colours on the stakes. Once you've found all four, locate the corresponding notes to guide you through a book cipher.

Each of the four notes will contain a series of numbers, like this:

364, 53, 6

The numbers represent:

The first number: the page number
The second number: the line number on that page
The third number: the word in that line

Use these numbers to decode the hidden message!
