Shakedown

When Eddie Sands decides to blackmail a famous Hollywood star whose sex life could ruin his screen career, he sets off a chain of events that leads straight to the white-hot center of Las Vegas, and brings down on himself the attentions of Tony Parisi, the mob's kingpin of Las Vegas, and FBI agent John Novak. "Shakedown is a gem. Stopped writing to read it, something I have sworn I would never do, but couldn't help it." - Elmore Leonard
