Just to expand on this a bit...
If you're interested in Vegas and gambling and oddsmaking, Casino is a great read. It was of course made into a movie with DeNiro, Pesci and Sharon Stone.
The characters played by DeNiro and Pesci were based on Lefty Rosenthal and Tony Spilotro.
In the early days of Vegas Rosenthal was one of the guys who really instituted big-time sports betting, and he was considered to be a very astute oddsmaker.
Spilotro meanwhile had a bit of a gambling problem, and he would try to hit Lefty up for some hot tips. Lefty's advice was always the same: don't bet.
