Garth estimated it to be two hours before dawn still. Since this new behavior seemed to demonstrate that the temple's services were through for the night, he got to his feet; his knees stung, as circulation returned to the areas where it had been cut off. He gazed up at the idol, as if in adoration, so that no one would question his failing to depart.

His eyes had long since become adjusted to the faint illumination, but now he found himself unable to distinguish details of carving that had been clear before; he blinked, but it made no difference. The scattered moonlight was not evenly distributed; had it merely shifted? No, it was growing uniformly darker. He had a moment of irrational fear that he was going blind before he realized what was happening.

The moon was setting.

That, of course, was why there were to be no more ceremonies, and why everyone was departing; with the moon down, the temple would be far too dark for use. People would run into one another, face the wrong way, and generally be unable to behave appropriately; even night-worshippers recognized that. He wondered what they did on moonless nights; were there no services at all? The starlight was plainly inadequate. Or what of overcast nights? Would torchlight from the streets or the glow of the volcanoes reflected off the clouds be enough? There would be no beam of moonlight falling on the great crystal.

Well, interesting as they might be, such considerations were irrelevant, since this night had been clear and moonlit. The spreading darkness would actually work to his benefit, since no one would be able to see him steal the gem; he studied the altar, measuring the distance between it and himself, so as to reach it quickly in the dark.

The three priests still stood behind it; the last worshippers had drifted out, and Garth realized they were looking at him, noticing this last straggler. That was not what he wanted. He turned and headed for the door, but stopped a foot from it, and turned to look again, hoping that anyone who saw him would not think that unusual.

Apparently the priests didn't, if they were able to see at all in the deepening gloom; Garth doubted they could see him any more, as he could no longer see them. Although he did not know for sure, it seemed unlikely that those squinty little human eyes could be as good as an overman's-though of course the priests' eyes were not quite normal.

A gong sounded somewhere, and the stone door swung slowly shut; whoever worked it thought Garth had left. He stepped away from it and lost himself in the darkness.

There were rustlings and whisperings in the blackness, which was now almost total; the moon was down. Although the dome made it very hard to locate sounds" Garth judged that the three priests were moving away from the altar. In a moment the sounds were cut off" as if a curtain had dropped across a doorway; straining, Garth could hear faint footsteps departing. The priests were gone.

Moving with all the stealth he could contrive, Garth inched across the broad stone expanse that lay between him and the altar; he could not see more than a few inches in front of him, and the quiet shuffling of his boots seemed magnified into a low roar by the echoes.

After what seemed hours, his outstretched hand touched something; he studied it with his fingertips, and decided it was a fold in the idol's cloak; he had missed the altar and hit the wall, off to the left. Cautiously, he felt his way along the fold until it swooped up out of reach, then moved on along the wall until he came to the idol's slippered feet, which he knew to be immediately behind the altar. He turned until he faced directly away from the wall, and peered into the darkness; he thought he could see the dim outline of the altar. He took a step forward and felt in front of him, reaching down to the height he estimated the altar to be; his hand brushed against a polished surface. Using both hands he groped about the altar-top and found the cloth-covered stone. He picked it up, cover and all, and tucked it under his cloak. Now he had only to get out of the temple undetected.

He knew that the concealed door to the antechamber was directly opposite the altar. He considered feeling his way along the wall until he found it, but rejected that idea; he might walk right into priests reentering the chamber, or at the very least be heard through whatever doorways they had departed by. Instead, he aimed himself by dead reckoning and set out across the floor.

Again, it seemed to take hours to cross; but at last an outstretched hand touched stone. He came up within inches of the wall, but could see only blackness; he felt along it with his hand, seeking a latch or seam or hinge. His left hand was occupied in holding the pilfered altar-stone under his cloak; it took a long time to cover an area with only his unencumbered right. He worked his way along, first three paces to the right, then twice that distance to the left, then back to the right once more; a feeling of desperation crept into him as his fingers found nothing but yard after yard of smooth stone.

Suddenly there was a sound behind him; he whirled, his right hand dropping automatically under his cloak to the hilt of his sword, but could see nothing in the darkness.

"If you return the stone you may go in peace, thief." He recognized the voice as one of the priests. He made no reply.

"You cannot open the door; only the priests of Tema know its secret."

Garth wondered how many were there, and how they had gotten so close to him without being heard; he judged the voice-for so far only one had spoken-to be ten, perhaps fifteen, not more than twenty feet away.

"Return the gem."

He needed time to devise an escape. "And if I do not?" he asked.

"Then you will die here."

Garth adjusted his grip, hugging the crystal closer to him, and drew his sword. "I have a counterproposal. You will open the door for me, or you will die, not I."

There could be no doubt that the priest or priests had heard and recognized the scrape of steel on leather as the blade left its sheath; there was a pause before the voice spoke again.

"It is possible that you may kill one or two of us before you yourself perish; if so, we will die in the sure knowledge that we have served our goddess and will be admitted to her realm for all eternity. You, on the other hand, will die damned forever for your sacrilege. I ask again, return the stone; it is not too late. Return it, and we will yet let you depart peacefully, even though you have drawn a weapon in our sanctuary."

Garth made no answer for a long moment, and the priest said nothing, apparently granting the thief time to consider the hopelessness of his position. The overman, however, was not considering options or the lack thereof, but rather was noticing that he could distinguish, very faintly, the outline of a lone figure a dozen feet in front of him. This was not the result of any adjustment; his eyes had long been at their extreme of sensivity. No, there was new light filtering in, the first dim gray of approaching dawn. That reminded him how long it had been since he last slept, and he suddenly felt weary even as he considered how the growing light would work to his advantage. The priests were undoubtedly accustomed to living almost entirely in darkness; they would not do well outside their temple in daylight, if he could once get out into the streets.

He wondered if the priest could see him at all; the light was not evenly distributed. Further, was he aware that he, himself, was visible? And it was now apparent that the priest was alone. Probably the lone man had been making a final inspection round of some sort, and tried to bluff out the intruder; unfortunately for him, his bluff was now ruined.

Knowing that he faced a single opponent, Garth finally struck upon a scheme.
