How can I get Governor Phatt's book?


Hint 1 of 6:
Just try walking back into his mansion and see if you can get it from him. 
You can talk your way past his guard fairly trivially.

Hint 2 of 6:
Pick up the book and see what happens.

Hint 3 of 6:
Phatt notices the difference in weight when you try picking up the book.
