The three Senators froze in their seats as he floated toward them, but only the slightest flicker of surprise crossed Seranis’s face. Perhaps Hilvar had already sent her a warning, or perhaps she had expected that, sooner or later, Alvin would return.
«Good evening,» he said politely, as if this vicarious entry were the most natural thing in the world. «I’ve decided to come back.»
Their surprise certainly exceeded his expectations. One of the Senators, a young man with graying hair, was the first to recover.
«How did you get here?» he gasped.
The reason for his astonishment was obvious. Just as Diaspar had done, so Lys must also have put the subway out of action.
«Why, I came here just as I did last time,» said Alvin, unable to resist amusing himself at their expense.
Two of the Senators looked fixedly at the third, who spread his hands in a gesture of baffled resignation. Then the young man who had addressed him before spoke again.
«Didn’t you have any-difficulty?» he asked.
«None at all,» said Alvin, determined to increase their confusion. He saw that he had succeeded.
«I’ve come back,» he continued, «under my own free will, and because I have some important news for you. However, in view of our previous disagreement I’m remaining out of sight for the moment. If I appear personally, will you promise not to try to restrict my movements again?»
No one said anything for a while, and Alvin wondered what thoughts were being silently interchanged. Then Seranis spoke for them all.
«We won’t attempt to control you again-though I don’t think we were very successful before.»
«Very well,» replied Alvin. «1 will come to Airlee as quickly as I can.»
He waited until the robot had returned; then, very carefully, he gave the machine its instructions and made it repeat them back to him. Seranis, he was quite sure, would not break her word; nevertheless he preferred to safeguard his line of retreat.
The air lock closed silently behind him as he left the ship. A moment later there was a whispering «hiss…» like a long-drawn gasp of surprise, as the air made way for the rising ship. For an instant a dark shadow blotted out the stars; then the ship was gone.
Not until it had vanished did Alvin realize that he had made a slight but annoying miscalculation of the kind that could bring the best-laid plans to disaster. He had forgotten that the robot’s senses were more acute than his own, and the night was far darker than he had expected. More than once he lost the path completely, and several times he barely avoided colliding with trees. It was almost pitch-black in the forest, and once something quite large came toward him through the undergrowth. There was the faintest crackling of twigs, and two emerald eyes were looking steadfastly at him from the level of his waist. He called softly, and an incredibly long tongue rasped across his hand. A moment later a powerful body rubbed affectionately against him and departed without a sound. He had no idea what it could be.
Presently the lights of the village were shining through the trees ahead, but he no longer needed their guidance for the path beneath his feet had now become a river of dim blue fire. The moss upon which he was walking was luminous, and his footprints left dark patches which slowly disappeared behind him. It was a beautiful and entrancing sight, and when Alvin stooped to pluck some of the strange moss it glowed for minutes in his cupped hands before its radiance died.
Hilvar met him for the second time outside the house, and for the second time introduced him to Seranis and the Senators. They greeted him with a kind of wary and reluctant respect; if they wondered where the robot had gone, they made no comment.
«I’m very sorry,» Alvin began, «that I had to leave your country in such an undignified fashion. It may interest you to know that it was nearly as difficult to escape from Diaspar.» He let that remark sink in, then added quickly, «I have told my people all about Lys, and I did my best to give a favorable impression. But Diaspar will have nothing to do with you. In spite of all I could say, it wishes to avoid contamination with an inferior culture.»
It was most satisfying to watch the Senators’ reactions, and even the urbane Seranis colored slightly at his words. If he could make Lys and Diaspar sufficiently annoyed with each other, thought Alvin, his problem would be more than half solved. Each would be so anxious to prove the superiority if its own way of life that the barriers between them would soon go down.
«Why have you come back to Lys?» asked Seranis.
«Because I want to convince you, as well as Diaspar, that you have made a mistake.» He did not add his other reason -that in Lys was the only friend of whom he could be certain and whose help he now needed.
The Senators were still silent, waiting for him to continue, and he knew that looking through their eyes and listening through their ears were many other unseen intelfigences. He was the representative of Diaspar, and the whole of Lys was judging him by what he might say. It was a great responsibility, and he felt humbled before it. He marshaled his thoughts and then began to speak.
His theme was Diaspar. He painted the city as he had last seen it, dreaming on the breast of the desert, its towers glowing like captive rainbows against the sky. From the treasure house of memory he recalled the songs that the poets of old had written in praise of Diaspar, and he spoke of the countless men who had spent their lives to increase its beauty. No one, he told them, could ever exhaust the city’s treasures, however long they lived; always there would be something new. For a while he described some of the wonders which the men of Diaspar had wrought; he tried to make them catch a glimpse at least of the loveliness that the artists of the past had created for men’s eternal admiration. And he wondered a little wistfully if it were indeed true that the music of Diaspar was the last sound that Earth had ever broadcast to the stars.
They heard him to the end without interruption or questioning. When he had finished it was very late, and Alvin felt more tired than he could ever before remember. The strain and excitement of the long day had told on him at last, and quite suddenly he was asleep.
When he awoke, he was in an unfamiliar room and it was some moments before he remembered that he was no longer in Diaspar. As consciousness returned, so the light grew around him, until presently he was bathed in the soft, cool radiance of the morning sun, streaming through the now transparent walls. He lay in drowsy half-awareness, recalling the events of the previous day and wondering what forces he had now set in motion.
With a soft, musical sound, one of the walls began to pleat itself up in a manner so complicated that it eluded the eye. Hilvar stepped through the opening that had been formed and looked at Alvin with an expression half of amusement, half of serious concern.
«Now that you’re awake,Alvin,» he said «perhaps you’ll at least tell me what your next move is, and how you man aged to return here. The Senators are just leaving to look at the subway; they can’t understand how you managed to come back through it. Did you?»
Alvin jumped out of bed and stretched himself mightily.
«Perhaps we’d better overtake them,» he said. «I don’t want to make them waste their time. As for the question you asked me-in a little while I’ll show you the answer to that.»
They had almost reached the lake before they overtook the three Senators, and both parties exchanged slightly selfconscious greetings. The Committee of Investigation could see that Alvin knew where it was going, and the unexpected encounter had clearly put it somewhat at a loss.
