Remember remember the 5th of November. The Gunpowder Plot has been seared into centuries of British popular history. Why have the events of October 1984 and the attempt to wipe out a Prime Minister and her cabinet not been committed to our public consciousness in the same way?

For the principal contributors in our series, the events of 40 years ago had a seismic impact on their lives. What, if anything, did the Brighton time bomb achieve?

When you get right down to it, everything in life is a matter of timing.

Any other evening, a knock at the door would put Patrick Magee on alert. As chance would have it, though, it being a Saturday, rent day, Magee, and the four other people in the flat with him on Glasgow’s Langside Road, are expecting the landlord.

Instead Magee opens the door to dozens of police and Special Branch officers who have over the past few hours massed around the address. They rush into the flat and overpower them before they have time to react.

After six years of trying, Special Branch finally have the man they have dubbed ‘the Chancer’, the man only a few of them as yet know bombed Brighton’s Grand Hotel.

Getting him to confess to it, or even speak, is another matter.

Spring 1985, six months on from the bomb at Brighton’s Grand Hotel that killed five men and women in town for the Conservative Party conference and came within feet of killing Prime Minister Margaret Thatcher.

Police are now satisfied that they have identified the man responsible for planting the bomb - Patrick Magee, aka the Chancer.

They just don’t know where he is.

Magee is back in Britain, planting a bomb in a hotel across the road from Buckingham Palace with an even longer timer fuse than the Brighton bomb. A police surveillance operation on another IRA suspect, meanwhile, leads to an unexpected result.

Patrick Magee plays mouse to the cat of the Southern Irish police, acting on a tip-off from their colleagues in the North.

He escapes back to Great Britain from Dublin and joins a new IRA unit planning a summer-long campaign targeting seaside resorts: more bombs in hotels and a new tactic - burying bombs on beaches. It will be the most concentrated wave of IRA attacks since the 1930s.

It's the day after one of the most shocking terror attacks in British history - a timebomb hidden in the Brighton hotel where the Prime Minister, Margaret Thatcher, and her cabinet are staying during the 1984 Conservative Party conference.

The casualties have all now been recovered. Four are dead, several of the injured are fighting for life.

Now all that remains is the rubble. Somewhere in here will lie the answer to who was responsible. Not the organisation – the Provisional IRA has already said it was them – but the individual human being, or beings, who left the bomb.

All the police have to do is find them.

The IRA’s Patrick Magee has left a bomb, under a bath, in room 629 of the Brighton’s Grand Hotel. It’s 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.

Or until 2:54am, when the bomb goes off. It's the biggest direct assault on a British Government since the Gunpowder Plot.

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.

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

The bomb will kill 5 people and injure 30.

The clock – the long-delay timer – nobody is meant to hear is counting down to 2.54am on the 12th October, 1984.

It's attached to a bomb, behind the panel of the bath of Room 629 in Brighton’s Grand Hotel, left there by a man who signed in as Roy Walsh.

Except he's not Roy Walsh.

Who is the man using his name? And how did he go from a childhood in the east of England to attempting to assassinate the Prime Minister and all her cabinet in the biggest assault on a British government since the Gunpowder Plot on 5th November 1605?
