When you get right down to it, everything in life is a matter of timing. The clock that propels this story went unheard for three weeks, three days, six hours and thirty-six minutes…until the bomb it was attached to went off at 2.54am on Friday 12 October, 1984. The day of Prime Minister Margaret Thatcher’s speech to the Conservative Party Conference in Brighton. Which means the Prime Minister and all her cabinet are guaranteed to be in the Grand Hotel. It's the biggest direct assault on the British parliamentary system since the Gunpowder Plot in 1605. And in the bomber's mind, it’s only the start.
