At Below-the-Lake, the revels were in full swing.

A hundred or so of My Lady Charlotina's closest friends had arrived to entertain their delighted (if surprised) hostess and themselves. The party was noisy. It was chaotic.

Jherek Carnelian had had no difficulty, in this atmosphere, in slipping away to the menagerie and at last discovering My Lady Charlotina's latest acquisition in one of the two or three thousand smaller caverns she used to house her specimens.

The cavern containing Yusharisp's environment was between one containing a flickering, hissing flame-creature (which had been discovered on the Sun, but had probably originally come from another star altogether) and another containing a microscopic dog-like alien from nearby Betelgeux.

Yusharisp's environment was rather dark and chilly. Its main feature was a pulsing, squeaking black and purple tower which was covered in a most unappealing kind of mould. The tower was doubtless what Yusharisp lived in on his home planet. Apart from the tower there was a profusion of drooping grey plants and jagged dark yellow rocks. The tower resembled the spaceship which My Lady Charlotina had had to disseminate (if it had disseminated, as such, being of unearthly origin).

Yusharisp sat on a rock outside his tower, his four little legs folded under his spherical body. Most of his eyes were closed, save one at the front and one at the back. He seemed lost in sullen thoughts and did not notice Jherek at first. Jherek adjusted one of his rings, broke the force-barrier for a second, and walked through.

"You're Yusharisp, aren't you?" said Jherek. "I came to say how interested I was in your speech of the other day."

All Yusharisp's eyes opened round his head. His body swayed a little so that for a moment Jherek thought it would roll off and bounce over the ground like a ball. Yusharisp's many eyes were filled with gloom. "You, skree, responded to it?' he said in a small, despairing voice.

"It was very pleasant," said Jherek vaguely, thinking that perhaps he had begun on the wrong tack. "Very pleasant indeed."

"Pleasant? Now I am completely confused." Yusharisp began to rise on the rock upon his four little legs. "You found what I had to say pleasant? "

Jherek realised he had not said the right thing. "I mean," he went on, "that it was pleasant to hear such sentiments expressed." He racked his brains to remember exactly what the alien had said. He knew the general drift of it. He had heard it many times before. It had been about the end of the universe or the end of the galaxy, or something like that. Very similar in tone to a lot of what Li Pao had to say. Was it because the people on Earth were not living according to the principles and customs currently fashionable on the alien's home planet? That was the usual message: "You do not live like us. Therefore you are going to die. It is inevitable. And it will be your own fault."

"Refreshing, I meant," said Jherek lamely.

"I see, skree, what you mean, skree." Mollified, the alien hopped from the rock and stood quite close to Jherek, his front row of eyes staring roundly up into Jherek's face.

"I am pleased that there are some serious-minded people on this planet," Yusharisp continued. "In all my travels I have never had such a reception. Most beings have been moved and (roar) saddened by my news. Some have accepted it with dignity, skree, and calm. Some have been angry to disbelieving, even attacked me. Some have not been moved at all, for death holds no fear for, skree, them. But, skree, on Earth (roar) I have been imprisoned and my spaceship has quite casually been destroyed! And no one has expressed regret, anger — anything but — what? — amusement. As if what I had to say was a joke. They do not take me seriously, yet they lock me in this cell as if I had, skree, committed some kind of crime (roar)! Can you explain?"

"Oh, yes," said Jherek. "My Lady Charlotina wanted you for her collection. You see, she hasn't got a space-traveller of your shape and size."

"Collection? This is a (roar) zoo , skree, then?"

"Of sorts. She hasn't explained? She can be a bit vague, My Lady Charlotina, I agree. But she has made you comfortable. Your own environment in all its details."

Jherek looked without enthusiasm at the drooping plants and dark yellow rocks, the mouldy tower sticking up into the chill air. It was easy to see why the alien had chosen to leave. "Nice."

Yusharisp turned away and began to waddle towards his tower. "It is useless. My translator is malfunctioning more than I realised. I cannot transmit my message properly. It is my fault, not yours. I deserve this."

"What exactly was the message," said Jherek. He saw a chance to find out without appearing to have forgotten. "Perhaps if you could repeat it I could tell you if I understood."

The alien appeared to brighten and walk backwards. The only difference between his back and his front, as far as Jherek could see, was that his mouth was in the front. The eyes looked exactly the same. He swivelled round so that his mouth aperture faced Jherek.

"Well," Yusharisp began, "basically what has happened is that the universe, having ceased to expand, is contracting. Our researches have shown that this is what always happens — expansion/contraction, expansion/contraction, expansion/contraction — the universe forming and re-forming all the time. Perhaps that formation is always the same — each cycle being more or less a repeat of the previous one — I don't know. Anyway that takes us into the realm of Time, not Space, and I know nothing at all of Time."

"An interesting theory," said Jherek, who found it somewhat boring.

"It is not a theory."

"Aha."

"The universe has begun to contract. As a result, skree, all matter not in a completely gaseous (roar) state already, will be destroyed as it is pulled into what you might call the central vortex of the universe. My own, skree, planet has already gone by now, I should think." The alien sighed a deep sigh. "It's a matter of millennia, perhaps even less time than that, before your galaxy goes the same way."

"There, there." Jherek patted the alien on the top part of its body. Yusharisp looked up, offended.

"This is (roar) no time for sexual advances, skree, my friend!"

Jherek took his hand away. "My apologies."

"At another time, perhaps…" Yusharisp's translator growled and moaned and he kept clearing his throat until it had stopped. "I am, I must admit, rather dispirited," he said. "A trifle on (roar) edge, as you might expect."

Jherek's plan (or at least an important part of it) now crystallised. He said:

"That is why I intend to help you escape from My Lady Charlotina's menagerie."

"You do? But the force-field and so on? The security must be, skree, very tight."

Jherek did not tell the alien that he could, if he wished, wander at large across the whole planet. The only intelligent creatures who remained in menageries remained there because they desired it. Jherek reasoned that it was best, for his purposes, if Yusharisp really did think he was a prisoner.

"I can deal with all that," he said airily.

"I am deeply grateful to you." One of the alien's brown, bandy legs rose and touched Jherek on the thigh. "I could not believe that every creature on this planet could be so, skree, skree, inhumane. But my spaceship? How will I escape from your world to continue my journey, to carry my message?"

"We'll cope with that problem later," Jherek assured him.

"Very, skree, well. I understand. You are risking so much already." The alien hopped eagerly about on his four legs. "Can we leave now? Or must secret preparations be made, skree?"

"The important thing is that you shouldn't be detected leaving by My Lady Charlotina," Jherek answered. "Therefore, I must ask you if you will object to a little restructuring. Temporary, of course. And not very sophisticated — there isn't time. I'll put you back to your original form before we go to Mongrove's…"
