Kenneth Lynch Looked at my 1963 edition, The "Gold Medal Original" Published by Frederick Muller Limited London. By arrangement with Fawcett Publications Inc. Chapter 8 last paragraph page 121 had the following " ...1976 is an election year. The President is already campaigning for a second term ... did you know that the President uses us, in the CIA, to spy on the other party? - that the Republicans are going to turn this whole business into something like the Dreyfus case" No mention of Watergate in the original.
Pam The book I'm reading has a 1963 publish date and the following comment "This edition includes slight revisions that the author made to the text in 1976."
Kenneth Since the making of the movie was obviously a big deal for Tevis, not least because it renewed interest in the novel, it would make sense for him to look over the MS and give it a few tweaks. This would have been around about 1976, as the comment Pam mentions does specify.
Jacob While there doesn't seem to be any obvious mention of it anywhere I have looked, it was reprinted in 1981 and it seems reasonable to assume that Tevis made the changes in the not inconsiderable space between.
Gary Duckworth I have the second printing of the UK 1976 Pan edition. Chapter 8, in section 2, "1988 Rumplestiltskin" - "Watergate changed nothing - nothing..." IS in my edition...as is The Dreyfus case, but that happened prior to WW1 - so that part is ok. But yes - how much else was changed from 1963 original US edition to this one?
