'When will I see her shining walls again, Taita?' my mistress sighed, and I could only tell her that I did not know.

  'If the gods are kind, we might be in Elephantine by this time next season when the Nile flood carries our ships down the first cataract. After that, our fortunes will ebb and flow like the river, with the hazards and fortunes of war.'

  However, this was not what she had brought me out on to the river to discuss, and now her eyes swam with tears as she asked, 'How long has Tanus been gone from us, Taita?'

  My voice choked as I answered, 'He set out on his journey to the fields of paradise over three years ago, mistress.'

  'So it is longer than that by many months that I last lay in his arms,' she mused, and I nodded. I was uncertain in which direction her questions were leading us.

  'I have dreamed of him almost every night since then, Taita. Is it possible that he might have returned to leave his seed in my womb while I still slept?'

  'All things in heaven are possible,' I replied carefully. 'We told the people that was how Tehuti and Bekatha were conceived. However, in all truth and seriousness, I have never heard of it happening before.'

  We were both silent for a while, and she trailed her hand in the water and then lifted it to watch the drops fall from her fingertips. Then she spoke again without looking at me. 'I think I am to have another child,' she whispered. 'My red moon has waned and withered away.'

  'Mistress,' I answered her quietly, and with tact, 'you are approaching that time of your life when the rivers of your womb will begin to dry up.' Our Egyptian women are like desert flowers that bloom early but fade as swiftly.

  She shook her head. 'No, Taita. It is not that. I feel the infant growing within me.'

  I stared at her silently. Once again I felt the wings of tragedy brush lightly past me, stirring the air and raising the hair upon my forearms.

  'You do not have to ask me if I have known another man.' This time she looked directly into my eyes as she spoke. 'You know that I have not.'

  'This I know full well. Yet I cannot believe that you have been impregnated by a ghost, no matter how beloved and welcome that ghost might be. Perhaps your desire for another child has fathered your imagination.'

  'Feel my womb, Taita,' she commanded. 'This is a living thing within me. Each day it grows.'

  'I will do so tonight, in the privacy of your cabin. Not here upon the river where prying eyes might discover us.'

  MY MISTRESS LAY NAKED UPON THE linen sheets, and I studied first her face and then her body. When I looked upon her with the eyes of a man, she was still lovely to me, but as a physician I could see clearly how the years and the hardships of this life in the wilderness had wrought their cruel change. Her hair was more silver than sable now, and bereavement and the cares of the regency had chiselled their grim message on her brow. She was growing old.

  Her body was the vessel which had given life to three other lives.'But her breasts were empty now, there was none of the milk of a new pregnancy swelling them. She was thin. I should have noticed that before. It was an unnatural thinness, almost an emaciation. Yet her belly protruded like a pale ivory ball out of proportion to those slim arms and legs.

  I laid my hands lightly upon her belly, upon the silvery streaks where the skin had once stretched to accommodate a joyful burden. I felt the thing within her and I knew at once that this was not life beneath my fingers. This was death.

  I could not find words. I turned away from her and went out on to the deck and I looked up at the night stars. They were cold and very far away. Like the gods, they did not care. There was no profit in appealing to them, gods or stars.

  I knew this thing that was growing within my mistress. I had felt it in the bodies of other women. When they died, I had opened the dead womb and seen the thing that had killed them. It was horrible and deformed, bearing no resemblance to anything human or even animal. It was a shapeless ball of red and angry flesh. It was a thing of Seth.

  It was a long time before I could gather the courage to return to the cabin.

  My mistress had covered herself with a robe. She sat in the centre of the bed and looked at me with those huge, dark green eyes that had never aged. She looked like the little girl I once had known.

  'Mistress, why did you not tell me about the pain?' I asked gently.

  'How do you know about the pain?' she whispered back. 'I tried to hide it from you.'

  OUR CARAVAN SET OUT INTO THE DESERT, traveling by moonlight across the silver sands. Sometimes my mistress walked at my side, and the two princesses frolicked along with us, laughing and excited by the adventure. At other times, when the pain was bad, my mistress rode in the wagon that I had equipped for her comfort. Then I sat beside her and held her hand until the powder of the sleeping-flower worked its magic and gave her surcease.

  Every night we travelled just as far as the next watering-station along the road that was now well beaten by the thousands of vehicles that had preceded us. During the long days we lay beneath the awning of the wagon and drowsed in the sweltering heat.

  We had been thirty days and nights upon the road when in the dawn we saw a remarkable sight. A disembodied sail upon the desert, moving gently southwards over the sands. It was not until we had journeyed on for many more miles that we saw how we had been deceived. The hull of the galley had been hidden from us by the bank of the Nile, and below the dunes the river ran on eternally. We had crossed the loop.

  Prince Memnon and all his staff were there to greet us. Already the squadron of new galleys had almost completed fitting out. It was the sail of one of these that we had first descried as we approached the river again. Every plank and mast had been cut and sawn on the great plains of Cush, and transported across the loop of the river. All the chariots were assembled. Hui had herded all the horses across the desert, and the wagons had carried their fodder with them. Even my gnu were waiting in their stockades upon the river-bank.

  Although the wagon caravans carrying the women and the children still followed, the main body of our nation had been brought across. It had been an undertaking that almost defied belief, a labour of godlike proportions. Only men like Kratas and Remrem and Memnon could have accomplished it in so short a time.

  Now only the first cataract still stood between us and the sacred earth of our very Egypt.

  We went on northwards again. My mistress sailed in the new barge that had been built for her and the princesses. There was a large and airy cabin for her, and I had equipped it with every luxury that was available to us. The hangings were of embroidered Ethiopian wool, and the furniture was of dark acacia wood inlaid with ivory and the gold of Cush. I decorated the bulkheads with paintings of flowers and birds and other pretty things.

  As always, I slept at the foot of my mistress's bed. Three nights after we sailed, I woke in the night. She was weeping silently. Although she had stifled her sobs with a pillow, the shaking of her shoulders had awakened me. I went to her immediately.

  'The pain has come again?' I asked.

  'I did not mean to wake you, but it is like a sword in my belly.'

  I mixed her a draught of the sleeping-flower, stronger than I had ever given to her before. The pain was beginning to triumph over the flower.

  She drank it and lay quietly for a while. Then she said, 'Can you not cut this thing out of my body, Taita?'

  'No, mistress. I cannot.'

  'Then hold me, Taita. Hold me the way you used to do when I was a little girl.'
