Based on real events happening on two days in Ireland and London a hundred years ago, "Shall Roger Casement Hang?" is the story of an interrogation. It is a confrontation between two men that asks fundamental questions about history, the British State, and personal and national identity. For both of them, the stakes get higher and more personal as violent events elsewhere and the revelation of Casement's sexuality change the rules of their struggle. When this conversation is over, one of them will be condemned to death, while the Empire that both men served will never be the same again.In one and the same moment, two sisters with one face, identical twins Isobel and Morag each have a story to tell about family, money, sex, truth and happiness - and about each other. It should be the same story about the same people, but the sisters are as divided from each other as two people can be. The play explores the ways in which they inhabit the world. By giving two very different but connected sides of the same coin, through humour and vitriol, the sisters show us how we think of ourselves and the world around us, and the shapes we get ourselves into in order to survive that world, asking fundamental questions about what matters to us and why.
