Why was the body put on the line? Chance? Or did someone want to halt the progress of the new electric railway out fom Cairo to the City of Pleasure being built in the suburbs? Was it another of Egypt's traditional revenge killings? Or had the murdered man somehow got caught up in the manoeuvrings of the sinister power groups jostling for position around the new railway? In this, the tenth novel in Michael Pearce's award-winning series, Old Egypt is pitted against New and in the middle is the Mamur Zapt. To answer these questions he has to look both in the luxurious quarters of the dazzling New Heliopolis and in the more humble houses of the dead man's village, and in neither place are things as straightforward as they seem. What is the significance of the tree of the Virgin? Does it matter that the gathering place for the Mecca caravan is only a mile or two away? And what of the ostrich that passed in the night?
