What do Horace Burgess, the Biltmore House, Southern women and a $10 bill have in common? Beats the hell out of us. But if you can answer that question, you'll be a lot closer to solving the "10 Stories High" mystery than we are. In April, a series of numbered envelopes declaring "Follow Your Narrative Urge!" and holding a variety of enigmatic, seemingly random clues began popping up around Atlanta. They were found dangling from trees, nestled between volumes in local bookstores and in the mail piles of local reporters. The public and local media instantly became captivated with the peculiar art project and committed en masse to solving the mystery. One ambitious code-cracker even created a wiki-style page to catalogue all of the clues. Two of us here at CL set out to solve the case, and ended up on a wild goose chase that took us all over the city. Which got us thinking, was the "10 Stories High" project about the proverbial journey and not the destination? When we wondered as much aloud in a blog post, the man/woman behind the curtain spoke up, commenting that, yes, such a notion was "at the heart of" the project. But, 'My story needs an ending," the mysterious wordsmith conceded. "10 Stories High" is spreading westward across the nation, with a new wave of envelopes recently arriving in Chicago, Minneapolis and Denver, among other cities. So, how does this frustrating, thrilling, engrossing, obsession-inducing story end? Maybe it does, maybe it doesn't.
