...(like earlier today) there were some kids (like you) who wanted to escape from the library. They found the librarians terribly dull and boring and the books old and dusty...or was it the other way around?
In either case, though it's hard to imagine why, those kids wanted out! So they dug around and about and over and under until they found the key (below) to unlock the first door.
Certain they were on their way, they solved puzzles, answered riddles, and figured out every clue the librarians set for them, and when, at long last, they thought they'd made it through, they discovered that the librarians had had the last laugh. Can you collect all the keys and decipher their message to the kids?
