Book excerpt: The Most Dangerous Man in the World is the definitive account of WikiLeaks and the man who is as secretive as the organisations he targets. Through interviews with Julian Assange, his inner circle and those who fell out with him, Fowler tells the story of how a man with a turbulent childhood and brilliance for computers created a phenomenon that has become a game-changer in journalism and global politics. In this international thriller, Andrew Fowler gives a ringside seat on the biggest leak in history. He charts the pursuit of Assange by the US and Sweden and how in the eyes of many Assange had become, according to the Pentagon Papers whistleblower, Daniel Ellsberg, 'the most dangerous man in the world'.
