Dal Nara slowly shook her head. "I don't think so," she said. "Nearly all of them were destroyed in the first few minutes. I saw Ship 16 racing up in an effort to escape, heading back toward the Galaxy, but there were cones hot after it and it couldn't have got away."

The quiet voice of Hurus Hol broke in upon us. "Then we alone can take back word to the Federation of what is happening here," he said. His eyes suddenly flamed. "Two things we know, he exclaimed. "We know that this dark star's curving path through space, which will bring it so fatally near to our own sun in passing, is a path contrary to all the laws of astronomical science. And we know now, too, that upon this dark star world, in those glowing cities yonder, live beings of some sort who possess, apparently, immense intelligence and power."

My eyes met his. "You mean-" I began, but he interrupted swiftly.

"I mean that in my belief the answer to this riddle lies in that glowing city yonder, and that it is there we must go to find that answer."

"But how?" I asked. "If we take the cruiser near it they'll sight us and annihilate us."

"There is another way," said Hurus Hol. "We can leave the cruiser and its crew hidden here, and approach the city on foot-get as near to it as possible-learn what we can about it."

I think that we all gasped at that suggestion, but as I quickly revolved it in my mind I saw that it was, in reality, our only chance to secure any information of value to take back to the Federation. So we adopted the idea without further discussion and swiftly laid our plans for the venture. At first it was our plan for only us three to go, but at Dal Nara's insistence we included the pilot in our party, the more quickly because I knew her to be resourceful and quick-witted.

Two hours we spent in sleep, at the suggestions of Hurus Hol, then ate a hasty meal and looked to our weapons, small projectors of the decohesion ray similar to the great ray-tubes of the cruiser. Already the ship's two shattered vibration-projectors had been replaced by new spares, and our last order was for the crew and under-officers to await our return without moving beyond the ship in any event. Then the cruiser's hull-door snapped open and we four stepped outside, ready for our venture.

The sandy ground upon which we stood glowed with the feeble white light which seemed to emanate from all rock and soil on this strange world, a weird light which beat upward upon us instead of down. And in this light the twisted, alien forms of the leafless trees around us writhed upward into the dusky air, their smooth black branches tangling and intertwining far above our heads. As we paused there Hurus Hol reached down for a glowing pebble, which he examined intently for a moment.
