"The most detailed, and consequently the most rewarding account of the Riemann Hypothesis is John Derbyshire's Prime Obsession. The author, a trained mathematician with a day job as an investment banker, moonlights as a novelist. This remarkable constellation of interests results in a math book that reads like a mystery novel. When, some 300 pages into the book, Derbyshire finally presents Riemann's conclusion, it is with literally breathtaking impact."
