Naguib Mahfouz is the Arab world's foremost fiction writer. Heinemann has published two of his books, Midaq Alley and Miramar, and is preparing his vast trilogy, the first volume of which, Between two Castles, was scheduled to appear last fall. Alleways, written in 1975, is the story of a boy growing up in the Cairo of 1919 to 1930, the period of Mahfouz's own boyhood there. The entire book in translation will be published in 1986 by Three Continents Press.
