I spent an incredible couple of months shadowing Gerry Adams, reputed IRA mastermind and leader of Sinn Fein, the Republican political party in Northern Ireland, as he toured Ireland and Britain. Halfway through my assignment it was announced that Prime Minister Tony Blair would meet him in Downing Street – the first time a Sinn Fein leader had been there since MIchael Collins in 1922. GQ allowed me to keep going with this article and follow him right to the front door. I was lucky to get closer to Adams than most journalists. I think it was worthwhile – even if I was nearly arrested for being a suspected terrorist myself. This is how it all happened.
