first thing I thought of when I saw the trailer for this was - hey it's Skink! sounds like he's not far from the mark.
from http://www.carlhiaasen.com "Skink, who first appears in Double Whammy, the bass-fishing novel, was conceived as sort of a wild hermit who avenges crimes against Nature. He needed an interesting background so I decided to make him a former governor of Florida, an honest guy who went mad trying to cope with the corruption all around him. One day, in the middle of his term of office, he suddenly bolts from the governor's mansion -- disappears into the woods, where he lives off roadkill and calls himself "Skink."
Originally, he was supposed to be sort of a walk-on character. I didn't imagine keeping him around for more than a couple of chapters, but then I found myself liking him tremendously. In a way, he became the moral compass of Double Whammy. Now, whenever his services are needed in another novel, I bring him out of the mangroves to raise hell. I love him because he hasn't mellowed one bit."
