The Last Samurai did have a somewhat storm-tossed passage to publication. It's possible if the Internet had flourished in something like its current form things would have gone better. Back in the day, if Tina Brown was tight with Hillary Clinton, a party for Clinton's New York Senate victory could bump the launch party for the book back to a point when the author was no longer capable of public appearances. Publicity involved dragging the authorial body here and there so that sentences could emerge from the authorial mouth. And the events had to be set up by a publicist competing for scarce public space. So if the author cracked up after the oft-deferred launch party and disappeared, if the publicist was in a miff, people who were excited about the book couldn't set up more congenial ways to talk about it. Couldn't unilaterally find venues independent of the whims of the publicist.
Anyhoo, the whole thing here.
