From one of the leading Irish playwrights comes the story of Mary and Lizzie - sisters in life, in love, living with Frederick Engels - they gave him safe passage through the dangerous poor for he believed in changing the world and they believed in him and in the end of the world. As in all his plays, McGuinness uses historical situations for a poetic exploration of the themes they suggest. McGuinness' earlier plays include Innocence, Carthaginians and Observe the Sons of Ulster Marching Towards the Somme.
