The Final Act of Finneus Fishbottom was my second library cache.  Here's how it worked:  The posted coordinates were for the library.  Once inside, the cache description directed the seeker to a locked box in plain site of the help desk.  Stenciled on the box were a set of coordinates for a dog tag hidden outside.  The dog tag had the call number of a hollow book in the reference section (so it couldn't be checked out).  The book contained a puzzle and riddle to solve the combination on the box.  So finding the cache was easy, getting it open was the challenge.  
I had a blast designing the book cover.  It's a play on our local reviewer Abe Froman the "Sausage King" from Ferris Bueller's Day Off. I also had some fun with the puzzle.  The alphabetic lock was configured to open with a particular four letter word.  The puzzle was four handmade alphabet blocks with a different color and letter on each side.  Matching the colors yielded six four letter words to unscramble: ring, rare, gilt, coin, loot, and rich.  The riddle inside the hollow book read, "Sincerest apologies if you sought knowledge amongst these pages of delicious sausage. But a final clue to a treasure greater than seasoned meats should null displeasure.  Six words do hint at a seventh most important to unlock a small box full of enjoyment."  Can you guess the word?
Opening the box, Finneus left a final message, "Line your pockets with gold, but truth be told, the real treasures are books - look about and behold." All the swag was gold themed including chocolate gold coins.  I think you'll agree we have an awesome library to allow such shenanigans under their roof.
