'Yes, I have seen them, and heard them referred to as trogs,' Taita replied.

Hannah looked a little annoyed. 'A term coined by the common people. The name we use is troglodyte. They were originally derived from a species of arboreal apes that inhabit the great forests in the south. Over the centuries that we have bred them in captivity we have been able, by surgical procedure and the use of certain herbs, to enhance their intelligence and aggression to the level at which they are most useful to us. By similar techniques we have been able to manipulate them until they respond completely to the will of the person who controls them. Of course, their minds are rudimentary and brutish, which makes them much more susceptible than humans to manipulation. However, we are experimenting with the same techniques on some of our slaves and captives. We have had exciting results. Once you are a member of the Guild I will be pleased to show them to you.'

Taita was sickened by these revelations. They are discussing putting together creatures that are no longer men, but aberrant monstrosities, he thought, but he was careful not to express his horror. These people are tainted with the evil of Eos. Their brilliance has been perverted and corrupted by her poison. How I miss the company of decent, honest men, like Meren and Nakonto. How I long for the fresh bright innocence of Fenn.

Some time later when they were returning from the library, he raised again with Hannah the subject of when he would be allowed to leave the Cloud Gardens and return to Mutangi, even for a short time. 'My companions must be much distressed by my continued absence. I should like to reassure them of my safety and well-being. Then I would be happy indeed to return here to begin my initiation into the Guild.'

'Unfortunately, my lord, the decision does not rest with me,' she replied. 'It seems that the Supreme Council wishes you to remain in the Cloud Gardens until you have been fully initiated.' She smiled at him.

'Be not downcast, my lord. This should not be longer than another year.

I assure you, we will do all in our power to make the time you spend with us as fruitful and productive as possible.'

The prospect of another year without being able to see Fenn or Meren appalled Taita, but he took consolation from the thought that the witch would not wait that long before she made her decisive move in the game she was playing with him.

His grafted parts continued to grow with amazing rapidity. He remembered Dr Lusulu's advice: 'You must learn to enjoy the manly parts that Doctor Hannah has returned to you. You must learn to delight in them, to glory in them.' Alone on his sleeping mat in the night he began to explore himself. The sensations aroused by his own touch were so intense that they intruded into his dreams. The lascivious devils that the imp of the grotto had set loose in his mind became more insistent and demand'

ing. The dreams were at once shocking and fascinating. In them he was visited by a beautiful houri. She displayed her womanly parts shamelessly to him, and he saw that they were as perfectly formed as an orchid. The woman smell and taste of her was sweeter than any fruit.

For the first time in almost a century he felt his loins erupt. It was a sensation so powerful that it went far beyond ecstasy or even agony.

He awoke panting and shaking, as though in fever. He was drenched in sweat and his own bodily fluids. It seemed an age before he could return from the far borders of his imagination to which the dream woman had transported him.

He rose and lit the oil lamp. He found the silver mirror that Rei had given him and went back to kneel on the mat. By the light of the lamp he gazed with awe at the reflection of his genitalia. They were still tumescent, and as the imp had shown him in the waters of the pool: perfectly formed, majestic and weighty.

Now I understand the urges that govern all natural men. I have become one of them. This thing that I have been given is the beloved enemy, a beast with two faces. If I can control it, it will bring me all the joy and delights that Lusulu spoke of. If it controls me, it will destroy me as surely as Eos plans to do.

When he returned to the library later that morning, he found it difficult at first to concentrate on the scroll that he unrolled on the low worktable in front of him. He was very much aware of a glow in the pit of his belly, and the presence under the skirts of his tunic.

It is as though another person has come to share my life, a spoilt brat who endlessly demands attention. He felt an indulgent proprietary affection for it. This is going to be a contest, a trial of wills to decide which of us is in command, he thought. But a mind like his, which had been honed to such perfection that it could suppress high levels of pain, an intelligence that had been trained to assimilate vast quantities of information, was able to deal with this much lesser distraction. He returned his full attention to the scroll. Soon he was so absorbed in it that he was only vaguely aware of his immediate surroundings.

The atmosphere in the library was quiet and studious. Although patrons were sitting at worktables in the adjoining rooms, he had this one to himself. It was as if the others had been warned to keep at a respectful distance. Occasionally the librarians passed through the room in which he sat, carrying baskets of scrolls to replace them on the shelves.

Taita took little notice of them. He heard the grille that barred the forbidden room being opened, and glanced up in time to see a librarian going through the open gate, a woman of middle age and unremarkable appearance. He thought nothing of it and went on with his reading. A little later he heard the grille open again. The same woman came out and locked it behind her. She walked quietly down the room, then paused unexpectedly beside Taita's table. He looked up enquiringly. She laid a scroll on the table top. 'You are mistaken, I fear,' Taita told her.

'I did not ask for this.'

'You should have,' said the woman, so softly that he could barely catch the words. She extended the little finger of her right hand, then touched her lower lip with it.

Taita started. It was the recognition signal that Colonel That had shown him. The woman was one of his people. Without another word she walked on, leaving the scroll on his table. Taita wanted to call after her, but restrained himself and watched her leave the room. He went on reading his own scroll until he was certain that he was alone and unobserved, then rolled it up and set it aside. In its place he opened the one that the librarian had brought him. It was untitled and the author

was not named. Then he recognized the hand that had formed the unusually small and artistically drawn hieroglyphics.: 'Dr Rei,' he whispered, and read on quickly. The subject that she1 was addressing was the replacement of human body parts by the process of seeding and grafting. His eyes skipped down the sheet of papyrus. He was intimately familiar with everything that Rei had written: her coverage of the subject was impressively detailed and lucid, but he found nothing new until he was almost half-way through the scroll. Then Rei began to describe how the seedings were harvested and prepared for application to the wound site. The chapter was headed: 'Selecting and cultivating the seedings'. As his eye ran on, the enormity of what she was so coldly enumerating crashed down on him like an avalanche. His mind numb with shock, he went back to the beginning of the chapter and reread it, this time very slowly, returning time and again to those sections that were beyond rational belief.

The donor should be young and healthy. She should have demonstrated at least five menstrual periods. Neither she nor her immediate family should have any history of serious disease. Her appearance should be pleasing. For reasons of management she should be obedient and tractable. If any difficulty is encountered in this area, the use of calming drugs is recommended. They should be administered with care so as not to contaminate the end product. There is a list of recommended drugs in the appendix at the end of this thesis. Diet is also important. It should be low in red meat and milk products, which heat the blood.
