Joyce's final work, 'Finnegans Wake', is his masterpiece of the night as Ulysses was of the day. He undermines traditional storytelling and all official forms of English and confronts the different kinds of betrayal - cultural, political and sexual - he saw at the heart of Irish history. Dazzlingly inventive, with passages of great lyrical beauty and much humour, 'Finnegans Wake' remains one of the most remarkable works of the twentieth century.
