"Maybe even they would reward me. You think so, Gregg Haljan?" He wanted to be on the winning side; this suited us. "Let's try it and see, Molo. I'll speak plenty of good words for you." Now, as we landed on the uplands, he said, "You will do best to free my hands." "Oh, no!" Snap declared. "But I am a good fighter. Something unexpected might come." "Too good a fighter," I said. "We trust you because we have to, Molo, but no more than is necessary." A small recess in the rocks was near us. We put Molo there, with his hands bound, and with Anita and Venza to guard him. Venza held the electronic gun; she knew how to fire it. The girls crouched in a depression about twenty feet away. They could see Molo plainly; if he moved, a flash of the gun would kill him. He knew that. The girls gazed at us as we were ready to start. "Good-by, Gregg. Good-by, Snap. Good luck!" "We won't be long. Sit where you are." Snap touched Venza's shoulder for his good-by. "Listen, Venza: Molo has already told us enough to enable us to find the ship. If he tries anything, kill him." "Right," she said. We left them. A minute or two, cautiously shoving ourselves along the rocks, and we were crouching there. The cauldron was about two hundred feet broad and fifty feet deep; an irregular circular bowl. The starlight gleamed on it, and there were dots of small artificial light. We saw a group of small metal buildings, very low and squat, like balls mashed down, flattened in a bulging disc-shape; between them were tiny skeleton towers. The towers, twice the height of a man, were spread at irregular intervals in a hundred-foot circle, with a group of three or four in the center. There seemed some twenty of them. Taut wires connected their tops, each tower with every other, so that the wires were a lacework above the small disc buildings. The bottoms of the towers were grounded with electrical contacts, and every tower had a ground connection with each other by means of cables. Far to one side, across the bowl from us, was a single globe-dwelling with lighted windows. From its ground doorway, a narrow metal catwalk extended like a sidewalk on the ground, winding and branching among the towers and discs. This was the exterior of the Wandl gravity station. It lay silent and dark, save for the starlight and the little lights on the towers. No sign of humans. Then we saw movement in the globe-dwelling. A man came to the doorway, gazed at the sky and went back. I whispered, "Which is the best entrance to the underground rooms?" We saw where, at several points, the winding catwalk terminated in low, dome-like kiosks, giving ingress downward. One was on our slope of the cauldron. "That's the one we'll try," Snap murmured.
