They used the door of the well for the lowering beam, hitching the cord about it. Then the merman noosed one end about him, and Dalgard, the door taking some of the strain, lowered him. The end of the cord was perilously close to the scout's fingers when there was a signaling pull from below, and he was free to reel in the loose line. He turned to the stranger. "You go. I'll watch them." The other waved his weapon to the corridor. There was some sense to that, Dalgard had to agree. He made fast the end of the cord and went in his turn into the dark, burning the palm of one hand before he was able to slacken the speed of his descent. Then he landed thigh-deep in water, from which arose an unpleasant smell. "All right--Come--" he put full force into the thought he beamed at the stranger above. When the other did not obey, Dalgard began to wonder if he should climb to his aid. Had the aliens broken through and overwhelmed the other? Or what had happened? The rope whisked up out of his hands. And a moment later a voice rang eerily overhead. "Clear below! Coming down!" Dalgard scrambled out of the space under the opening, heading on into the murk where the merman waited. There was a splash as the stranger hit the stream, and the rope lashed down behind him at their united jerk. "Where do we go from here?" The voice carried through the dark. Scaled fingers hooked about Dalgard's right hand and tugged him on. He reached back in turn and locked grip with the stranger. So united the three splashed on through the rancid liquid. In time they came out of the first tunnel into a wider section, but here the odor was worse, catching in their throats, making them sway dizzily. There seemed to be no end to these ways, which Raf guessed were the drains of the ancient city. Only the merman appeared to have a definite idea of where they were going, though he halted once or twice when they came to a side passage as if thinking out their course. Since the man from the arena accepted the furred one's guidance, Raf depended upon it too. Though he wondered if they would ever find their way out into the open once more. He was startled by sudden pain as the hand leading him tightened its grip to bone-bruising force. They had stopped, and the liquid washed about them until Raf wondered if he would ever feel clean again. When they started on, they moved much more swiftly. His companions were in a hurry, but Raf was unprepared for the sight which broke as they came out in a high-roofed cavern.
