I’m hunting the bones of the outlaw Leslie Cox. For a long time rumor was that Cox, a surly, dark-haired drifter from up around Fort White, Florida, was hiding out here in the Ten Thousand Islands, prowling its knotted creeks and salt marsh bogs, and just might turn up on your porch one evening to settle old scores. “Unless Watson killed him, which nobody believed, Cox was still there,” Peter Matthiessen writes in Shadow Country, his fictional re-jiggering of this region’s most hard-dying legend. Of course we’re talking ages ago. Cox, even if he did live out his life in this wilderness, is long gone now.
