The Fix - Declan Hill

The Fix is the most explosive story of sports corruption in a generation. Intriguing, riveting, and compelling, it tells the story of an investigative journalist who sets out to examine the world of match-fixing in professional soccer.

From the Introduction:

Understand how gambling fixers work to corrupt a soccer game and you will understand how they move into a basketball league, a cricket tournament, or a tennis match (all places, by the way, that criminal fixers have moved into). My views on soccer have changed. I still love the Saturday-morning game between amateurs: the camaraderie and the fresh smell of grass. But the professional game leaves me cold. I hope you will understand why after reading the book. I think you may never look at sport in the same way again.
