What is the setting of The Sniper by Liam O'Flaherty?

The setting of "The Sniper" is integral to the narrative, for it draws its action from the Irish civil war. The story takes place in Dublin, Ireland, in June 1922. At this time, the Irish civil war has been going on for several months. The Republicans hold the Four Courts judicial building, but the Free Staters are attacking them with heavy arms.
