I didn't pay a lot of attention to this thread when it started, but a friend gave me "Grand Slam" to read; I'm now about half finished.
Interesting book! It is emminently readable, and highly entertaining. I must say, though, that the factual "fast and loose" is weird, to say the least.
There is a episode in the book in which Jones' grandfather, R.T. Jones, meets Bobby in NY on his return from winning the '26 British Open. The book says that the elder Jones had just doubled his fortune by becoming one of the first domestic producers of silk, after importing silkworms to Canton, GA, where he lived had had a mill.
The reality is that Canton was renamed in 1833 when some local residents attempted to start a silk trade comparable to Canton, China by importing silkworms to north Georgia. (The previous name had been Etowah, among other things, I think) The silk idea failed, (I've read that the climate was somehow not suited) but the name stuck. The R.T. Jones mill was a cotton mill (remember, this is Georgia!) that primarily produced denim. All of this information is available on the town's website, and if there was ever a silk industry in Canton, GA, no mention is made of it there or anywhere else. There is today no silk industry, and never has been one to speak of.
R.T. Jones (the grandfather) was a hugely successful man financially. The hospital in Canton was named after him, as well as the mills and about a jillion other things in that town. Why that would need to be embellished by a story about silkworms is not something I understand, and, as mentioned earlier, calls other things into question needlessly.
