‘To have a father is always big news,’ according to the narrator of Sebastian Barry’s early novel, The Engine of Owl-Light. Stephen Dedalus puts it differently in Ulysses: ‘A father is a necessary evil.’ But later, he qualifies this: ‘Paternity may be a legal fiction. Who is the father of any son that any son should love him or he any son?’ Colm Tóibín has repeatedly squared up to fathers as well as mothers in his own work (a dead father haunts the family in Nora Webster, and fatherhood is a central theme in The Heather Blazing).
