LONDON – Anyone who has read The Yacoubian Building, a novel published in 2002 by the Egyptian author Alaa-al-Aswany, will regard the revolution in Egypt as long overdue. The novel’s readers will not have been astonished by the ease with which the rotting hulk of Hosni Mubarak’s regime was dashed against the rocks, nor by the spirit and courage of those who engineered this extraordinary piece of history.
