Think coherently. You must breathe. We have some more building to do. Think of something, say it in your mind, now.

Unbidden, the Green Paternoster floated up through Dom's consciousness, the last words he would say before climbing into his cot as a child, after ending the night prayer with 'God bless the household robots.'

He galloped through it. It was senseless gibberish now, the centuries had twisted the words, but it still had power.

'Green Paternoster, Sadhim was my foster, he saved me under the poisoned tree, He was made of flesh and blood to send me my right food, mine right food and air, too ...'

Good.

'... that I might be a FOE, and stop at two, To read in that sweet book which the great gods shoop...'

Good.

Dom plunged on recklessly, tasting the words: '... open, open, save me, Dead, Dead Chel Sea, Halve the population roster and say the Green prayer PATER NOSTER !'

In the silence the tank man said: 'Dom, you now have vocal chords. You are breathing. You have built yourself a mouth. There is something you must want to do.'

Dom screamed.

He examined himself in the full-length mirror. Everything was there, and in full working order. The tank, working from his body memory, had duplicated nails, teeth, DNA patterns and even healed the scar on his chest. Dom rubbed the place bitterly, remembering the flight in the marsh.

Isaac creaked across the room and handed him his clothes. He dressed himself slowly.

There was one alteration. Before he had been jet black and decently hairless, the result both of See-Why's healthy ultra-violet and the tannin injections. Now he had hair to the waist and, like the rest of him, it had a greenish tint.

The bouncy little Creapii doctor in charge of the hospital tanks had explained it carefully, with a rare grasp of colloquial Janglic. But then Creapii could so easily assume the mannerisms of other races.

'It's called googoo. Of course, I needn't tell you that. I used to go out on the hospital rafts once, but we've come a long way from those primitive limb replacement tanks.

'Anyway, Mr Chairman, it is alive in its own right. It is in fact a highly-complex organism under your control. I can guarantee that it matches your body almost on the atomic level. It will have certain advantages, of course - your heat tolerance, for example... ah, yes, at your age I'm not surprised you should ask. Yes, your children will be human in every respect—' and the doctor made a surprisingly apt dirty joke. 'But be careful of misunderstandings. It is now yo u , not some alien slime. The colour? The state of the art, I'm afraid... come back in, oh, ten years and I guarantee that we can turn out a body with not even a trace of green. As for the hair, well, absence of hair is not yet a generic characteristic of a Widdershins. I'm sorry, at the moment it's a warts-and-all process.

'Before you go, Mr Chairman, I would like to show you the hospital. I'm sure the staff would like to meet you, uh, unofficially. As for myself, I am proud to shake you by the manipulatory appendage.'

Dom fastened his choker collar and turned round.

'How do I look?'

'Pale green, boss,' said Isaac soberly. He indicated a small plastic case.

'There are some body cosmetics here, boss. Your mother sent them.'

Dom turned again and ran his pale green fingers over his face. The googoo had tried to follow body pigmentation as far as possible, but even so he looked as if he had been on a copper-rich diet for a year. He had watched himself on the newscasts while he was recuperating. The fishermen were already fiercely proud of a Chairman who was completely green, and didn't seem to mind that it was not as a result of prowess on the hunting sea. But his mother's unspoken comment was that it would offend offworld dignitaries.

'Beng take them!' he said out loud, 'What do they matter. Anyway, green is a holy colour.'

Outside the little hospital six security guards stood to attention as Dom walked out, followed by Isaac and, at a discreet distance, some of the hospital staff.

Hrsh-Hgn waited beside them. He was holding a high-velocity molecule stripper, and looking sheepish.

'It suits you,' said Dom.

'I am a pacifist, ass befits a philosopher, and thiss is barbaric.'

They boarded the Chairman's barge, which was joined by five flyers as soon as it was airborne.

Dom stared unseeing at the seascape.

'Who is replacing Korodore?' he asked after a while.

'Darven Samhedi, from Laoth.'

'A—a good man.' But still, it took more than efficiency to be security man on Widdershins. 'Will the phnobes take to him?'

'He is rumoured to have shown shape-hatred. We will ssee,' Hrsh-Hgn looked down at Dom, 'You were fond of Korodore.'

'No. He didn't encourage friendship, but ... well, he was always there, wasn't he?'

'Indeed.'

Dom turned in his seat and looked at Isaac.

'And if you say one sarcastic word, robot ...'

'No, chief. It crossed my mind that Lord Korodore was somewhat over-enamoured of miniature cameras but that was his job. He was a regular guy. I mourn.'

Four months ago, thought Dom, someone killed him and tried to kill me.

I am going to find out why.

A light drizzle was blowing when the squadron landed at the second Sabalos home, a small walled dome near the administrative centre of Tau City. Even Lady Vian came out to meet him, bundled in a heavy cloak, and looking slightly happier for being in a city. Tau was not overwhelmingly cosmospolitan, though a sight more so than the Home domes.

'That is not a becoming colour,' were her first words.

They dined in the small hall. Down the table Samhedi and the senior members of the household eavesdropped respectfully. Joan, after a polite inquiry about the hospital, was silent.

Vian looked across at her son. 'Why don't you try those body cosmetics?'

Dom caught the eye of a security man standing against the wall. He had one green hand and a green patch extended all down one cheek and into the colour of his uniform. The man saw him and winked.

'I prefer it this way.'

'Perverse vanity,' said Joan, 'But still, I agree. A piebald grandson I could not bear, but at least he is a uniform colour.'

She pushed her plate aside and added: 'Besides, green is a holy—'

'Green is the colour of chlorophyll on Earth, certainly,' said Vian, 'But here the vegetation is blue.'

Joan glanced up quickly at the Sadhim logo inscribed on the ceiling and then gazed at her daughter-in-law, her eyes narrowing. Dom watched them interestedly - too much so, for Joan sensed him and folded her napkin deliberately. She stood up.

'It is time,' she said, 'for our evening devotions. Dom, I will see you in my office in one hour's time. And we will talk.'
