Now we've lived together in contentment, more or less, for nigh on twenty year. Like turtle doves. - In prison, I mean, for fuck's sake, the chances of that.PJ and Christy: sworn enemies destined to share one small room for twenty years. As the two men recall the joys and torments of life outside - the childhood excursions, a deadly brawl, past loves and summer dresses - slowly they uncover the tragic events that have lead them to their cell in Montjoy. A play that explores our capacity to commit the deadliest of crimes but also our capacity for survival, reconciliation and love, ON BLUEBERRY HILL by Sebastian Barry (twice winner of the Costa Book of the Year) premiered in a Fishamble production at the Pavilion Theatre as part of the Dublin Theatre Festival and at the Centre Culturel Irlandais in Paris in October 2017.
