The National Theatre's second play of the Brian Friel festival, Living Quarters, which opens in the Peacock on Wednesday first saw the stage light in the Abbey in 1977. There are echoes of Racine's Phaedra in its story of a hero returning from war to be reunited with his young wife and a grown son. Eugene O'Neill, too, used this particular triangle to effect in Desire Under the Elms. Friel's warrior is an Irish army commandant, played by Clive Geraghty (right), arriving back in his Donegal home town from a UN stint in which he has performed an act of great courage. But he faces a different sort of ordeal on his return, and one for which his military training has not equipped him.
