A gripping re-imagining of one of the most ambitious assassination attempts against the British establishment from one of the finest novelists of his generation. 'A meticulous and gripping reimagination of the Brighton bomb' Observer, Best Novels of 2015 In September 1984, a man calling himself Roy Walsh checked into The Grand Hotel in Brighton and planted a bomb in room 629. The device was primed to explode in twenty-four days, six hours and six minutes, when intelligence had confirmed that Margaret Thatcher and her whole cabinet would be staying in the hotel. Moving between the luxurious hospitality of a British tourist town and the troubled city of Belfast, and told from the perspectives of a young IRA explosives expert, the deputy hotel manager and his teenage daughter, High Dive is a taut and tender retelling of one of the most ambitious assassination attempts against the British establishment.
