As a group of Western tourists travel down the Nile on the steamer Korosko towards the historical sites near Egypt’s southern border, they are kidnapped by a marauding band of dervishes who demand their conversion to Islam. Cut off from the world, deprived of the comforts of civilized society and shaken in their beliefs, they will have to overcome the most arduous obstacles to regain their freedom and safety. This edition contains a wealth of material about the author’s life and works, notes and a bibliographic section.
