I would recommend Eliot Asinof's (which the author does too) "Eight Men Out" as a better, more balanced account. Also a very, very good movie if you'd rather not read the book. A great ficitional account, I thought, was "Hoopla" by Harry Stein, which came out a few years ago. I think both of those do a better job in giving us the feel for Chicago and America in those days. A good case is made in both for Buck Weaver as another reluctant participant in the scandal who was probably penalized a little more severely than he deserved.
Couple this with Frommer's clumsy writing style, lack of citations, and bizarre style of quotation, and one is left with a book that was not worth the time spent reading it. I was left with no greater insight into Jackson the man than before I first picked up the book.
