The bomb is set for 12 October 1984 - but the IRA have been building to this for decades

It's the night of 17 September 1984. The guest in room 629 of Brighton’s Grand Hotel has ordered a bottle of vodka and three cokes. It seems he is having a small party.

A few minutes before, the guest – who signed in two days ago as Roy Walsh – put the back on the side of the bath in 629’s en suite.

Behind that he has left a bomb, timed to go off in three weeks, three days, six hours and thirty-six minutes, at 2.54am on Friday 12 October. The day of Prime Minister Margaret Thatcher’s speech to the Conservative Party Conference in Brighton.

And the Prime Minister and all her cabinet, as this man who calls himself Roy Walsh knows, will be staying in the Grand Hotel.

It's the biggest direct assault on the British Government since the Gunpowder Plot.

The bomb will kill 5 people and injure 30.

It's the latest in a line of Irish republican attacks in England that stretches back to 1867.
