A real-life literary mystery!

Hey all. It's been a while, how are you? I've been busy but I didn't mean to stay away for quite so long. Well right now I want to tell you about this nifty thing McSweeney's is doing with its new book, The Clock Without a Face. Have you heard about it? The book itself, which is a large colorful cardboard affair the way books for small children sometimes are, is a detective story: The grand Emerald Khroniker clock has been stolen. Detective Ray Dodge figures out who did it and where the bejeweled numbers are hidden, but he keeps it to himself. In real life, twelve numbers have been buried in the ground in secret locations across the U.S. The pieces were made by jewelry designer Anna Sheffield, and anyone who can crack the clues/visual codes/anagrams/rebus puzzles/etc. to find and dig up a jewel can keep them. Gamers jumped on it before the book was even out last week. Will you play along?
