Without intending to belittle other writers, for me Edna O'Brien, together with John McGahern, is the greatest Irish author of the past decades. Both had in common their books were banned in Ireland.
Above's interview from 1976 is on her trilogy "The Country Girls".
The interview above's taken in 2012.
And this one after release of ‘The Little Red Chairs’ (2015)
Enjoy!
