Life's Greatest Secret is the story of the discovery and cracking of the genetic code. This great scientific breakthrough has had far-reaching consequences for how we understand ourselves and our place in the natural world. The code forms the most striking proof of Darwin's hypothesis that all organisms are related, holds tremendous promise for improving human well-being, and has transformed the way we think about life. Matthew Cobb interweaves science, biography and anecdote in a book that mixes remarkable insights, theoretical dead-ends and ingenious experiments with the pace of a thriller. He describes cooperation and competition among some of the twentieth century's most outstanding and eccentric minds, moves between biology, physics and chemistry, and shows the part played by computing and cybernetics. The story spans the globe, from Cambridge MA to Cambridge UK, New York to Paris, London to Moscow. It is both thrilling science and a fascinating story about how science is done.

It is to Cobb's considerable credit that he manages to provide such an authoritative but nevertheless thrilling narrative, while also establishing, on a more serious level, how the genetic code has made its impact on everyday life 50 years since its discovery. In short, this is a first-class read. -- Robin McKie * Observer *
