So it was that I found myself in the mid-nineteen seventies in another small house, this time in Co. Wicklow south of Dublin, with a young family of my own and a slightly less imposing radio set, listening to the rain in the trees and to the news of bombings closer to home-not only those by the Provisional IRA in Belfast but equally atrocious assaults in Dublin by loyalist paramilitaries from the north.†

All in vain, however, for the man stepped out of the line; but instead of finding a gun at his temple, he was thrown backward and away as the gunmen opened fire on those remaining in the line, for these were not Protestant terrorists, but members, presumably, of the Provisional IRA.†
