Despite innovative work by younger writers, there remains a prominent strain in Irish literature of what we might call the ‘sad but nice’: tales of desperation elegantly unfolded, popularised by William Trevor and John McGahern and refined by Colm Tóibín and Mary Costello. A newcomer in this lane is Billy O’Callaghan, whose previous books have been so orgiastically praised by the Booker Prize winner and former literary editor of the Irish Times John Banville that I began to think O’Callaghan might be another of his pseudonyms.
