So I really feel sorry for Harper Lee -- there were probably 300 pages of good writing that went up in smoke because she set an impossible standard for herself. My advice to you all is to seek high quality, but remember that eventually worse is better, and it's time to ship it.
Regardless, it's an iconic true crime book you could (and should) read.
I always thought Lee and Capote were just very close childhood friends, who read each others works before anyone else, and suggested changes. Nothing more, nothing less.
Not saying it isn't possible, one would just generally assume that the "ghost" would be the more experienced author.
Capote's fame is mostly due to his "jet set" social life, not the quantity or quality of his work.
