A cat may be at the center of a break-in at the library.

I'm Kat Jones and my very first client needs my help to find the person responsible for swapping an ancient book with a fake. As if that isn't baffling enough; where they found the fake is a place no one knew existed.

To solve this case, I'll need to team up with Rusty. What we discover is a treasure trove of secrets that lead to the origin of the book and not who but what four-legged creature may be responsible.
