The Dark, John McGahern's second novel, is set in rural Ireland. The themes - that McGahern has made his own - are adolescence and a guilty, yet uncontrollable sexuality that is contorted and twisted by both a puritanical state religion and a strange, powerful and ambiguous relationship between son and widower father.Against a background evoked with quiet, undemonstrative mastery, McGahern explores with precision and tenderness a human situation, superficially very ordinary, but inwardly an agony of longing and despair.
