I have a first edition of Deliverance.
When I read it years ago, after seeing the movie several times, I was surprised at the meta-physical content of the novel.
The scene where Jon Voight climbs out of the gorge is treated a whole nother way in the book...it's man against nature as well as man against man. But the climber becomes one with the wall and the experience, even though success means murder.
A damn good fiction writer, and a fine poet, James Dickey.
"Don't come 'round here again, doan come up here no mo'; I'd kinda like to see this town die peaceful."
And that black-eyed nurse at the end...hubba, hubba.
