But Dom was a different matter. The Institute was at a loss to understand why. His father had also been a high-probability Discoverer, and there had been no difficulty there. Yet something prevented Dom from being conveniently removed. He was too lucky.

Something wanted him to discover Jokers World.

'Yes,' said Dom. 'It's the Jokers.'

'So we think,' said Asman. 'Do you know why we can't let you?'

'I think I can follow your reasoning,' said Dom. 'You fear the Jokers. That's because you don't know them. You think that contact with even the remnants of their culture will destroy us. I expect you have some idea that men are better off without gods.'

'You laugh at us. Oh, we can't deny that the Joker artifacts have done something to stimulate interracial co-operation.'

Dom heard himself shout: 'They caused it! The Creapii invented the matrix engine just so that they could find other lifeforms to help them answer the Joker riddles!'

'That is so. But Dom, listen. Before Sadhim, before star travel even, you know that most men believed in some kind of omnipresent god? Not the Sadhimist Small Gods, answerable to natural forces, but a real Director of the Universe? But if it had turned out that He really did exist chaos would have been let loose on the planet. He would have ceased to become a matter of comforting Belief but a matter of fact - you don't believe in the sun, either. And men would have perished of a cosmic inferiority complex. You can't live and know of such greatness.

'We need the idea of Jokers because they are a unifying force among the races, but we can't afford to find their world. Supposing it is dead - is that the end of even the greatest race? If they still live, will they enslave us or ignore us? Or worse, befriend us?'

'We can only let you go now to the dark side of the sun. But you must understand that we can't let you return.'

'I know what the Jokers World is,' said Dom slowly. 'I've known for some time, I think, without realizing it. And I think I'm coming to realize where it is. There is only one Sun in the universe - our universe - and the Jokers gave it to us. Will you lock your fleet on to this ship?'

Asman nodded.

'Then follow me.'

Interspace glowed around him. Dom switched off the set and tried to ignore the orange-gold glow that filled the ship and in which it floated.

To no one he said: 'Why now? And why me?'

Ig shrugged, and turned his pointed, rat-like nose towards him. He spoke. The words arrived in Dom's head without the need for a cumbersome physical route.

'The trouble was that we never found a way to become empathic. Telepathy - that's merely a higher form of speech. But to know how another being, another creature feels - that is impossible.'

'You were lonely,' said Dom. 'All those empty years ...'

'Isaac would say: close, but no cigar. We searched even the alternate universes, it is true, right along to the dark impossible ones that are the stuff of nightmares. There was life. The Bank and Chatogaster are small fry. In some universes the very suns live. There is a galaxy that sings. In one universe, over there—' a paw pointed and one claw disappeared momentarily into another continuum— 'there is nothing but thought, which pervades all. Not only thought, but understanding. But it is alien to us. How blithely you use the word alien: you have no idea how alien a thing may be.

'We discovered - as the Creapii are discovering - that the ultimate barrier is one's viewpoint. Dimly they realize that even their most objective statements about the universe cannot be freed from the Creapii taint because they ultimately derive from Creapii minds and emotions. That's why they are the great ambassadors of inter-racial harmony, and why they try so hard to be everything but Creapii.'

'So you invented us,' said Dom. 'At least that theory is true? You wanted to get, uh, different points of view?'

'Close again. All we had to do was make it easier for intelligent life to evolve. That at least is not difficult; it's well within the range of your sciences. Though it was damn difficult to hit the right combination for cold-helium life. By the way, I have a small bomb surgically implanted in me. The Earthmen did it. Very subtle. I wouldn't worry; I have inactivated it.'

Ig paused and scratched an ear.

'We left artifacts to tantalize,' he said. 'I'm afraid we cheated. Be sure that before we left we were very thorough in cleaning up the galaxy. On some worlds we had to build an entirely new crust, down to the fossils. We had to replace metals in the grounds as ores, replenish oilfields, relay coal measures - we wanted to make sure you had a start in life. We gave you reconditioned worlds, but we left you the Towers and the Chain Stars and so on. All cultural fakes, I'm afraid. Made to awe rather than inform. But we had to leave the clue. That was artistically correct.

'The dark side of the sun,' said Dom. 'It was two clues. If you hadn't wanted us to translate it, we never would have done. That was clue one. After all, we couldn't even have translated Phnobic without the phnobes there to help us out. And the sun - you turned your back on intelligence, and became dull-minded animals.'

'Please! Swamp-igs are reasonably bright, considering their environment. We selected our new selves with care. Believe me, it is pleasant to have no enemies and to lie in the warm mud. We had to build in safeguards - a genetic twist to make us lucky animals, so that we were venerated rather than hunted. And an alarm, so that when the time came we would remember. These little bodies have made good hiding places.'

'I'll just ask again: why me?' said Dom.

'You live at the right time. You are naturally cosmopolitan. You come from Widdershins. That was our world, once. Long ago, of course. You are rich, there is a certain amount of glamour attached to your position. Let's say it was fate.'

He squinted through the canopy at the glowing, heatless fires of interspace.

'Excuse me,' said Dom. 'But you don't look like a super race.'

Ig's paws were darting rapidly across the console of the matrix computer. He looked up and stared at Dom -

- Dom rubbed his eyes. 'I'm sorry,' he said. A few seconds later he tried to remember what he had seen during that moment of contact, but it had gone now, leaving only an impression of greatness and understanding.

'Thank you,' said Ig quietly. 'You see, people expect an advanced race to land in golden ships and say, "Throw away your weapons, cease fighting among yourselves, and join the great galactic brotherhood." It isn't like that. Young races do that.'

'What happens now?'

'Now?'

. . . we will meet you, came the thought. Together, perhaps, we will see the universe as it really is. And when we meet you, we will do so as equals. We are all mere sub-species of the one race of bright sun dwellers, after all. And the whole is infinitely greater than the sum of the parts. Now...

'Now,' said Ig, 'we will talk.'

The fleet hung against the shimmering bulk of Widdershins. Other ships were flashing into existence all through the system, as the followers homed in on the interspace shadow. The radio was a gabble of many tongues.

'They're going to fight it out!' moaned Joan. 'Oh my God, they're going to fight!'

The control deck of the Earth command ship was dominated by the big state-of-space circlescreen. They watched the incoming ships form a rough pattern. Their commanders had been doing some very rapid diplomacy.

Asman walked over from one of the control desks, shaking his head.

'I'm sorry,' he began. 'Widdershins eh? Are you Widdershines Jokers, then? You were only a small colony to begin with, it's not inconceivable . . . '
