It was a courtyard that Jupiter found himself looking into. The orange sun beat down warmly on the flagstone pavement, on the large shallow pool in the center of the court. There were Anolyn in the pool, fifty or sixty of them, floating like purple jellyfish. Humans, too. Pink-skinned Caligans, wild Kagans, fighting men and the stolid green porters. Even the tailed, ape-like Begans were represented. They moved with a dreamy apathy like sleepwalkers. "Their minds are under the control of the Anolyn in the pool," Tabak breathed into his ear. "The Anolyn have entered into them. They feel and see and hear exactly what their human vehicles do." Jupiter's face was drawn. He could hear music. The scale was all wrong, it registered discordantly in his ears. It was coming from one of the balconies that rose in tiers above the courtyard. Food and drink had been spread on cloths. "They'll be here for days," Tabak whispered. Hardened as Jupiter was, nevertheless he was sickened at the deeds being enacted under his eyes. They were unthinkable. His fists clenched. He could bring himself to watch no longer. He turned his head away, said hoarsely: "Let's clear out of here." Tabak was silent as she led him back down the tunnel to the vaulted canal. "Can you swim?" she asked as they reached the water's edge. "Yes." The girl stripped off the boj, laid it on the ledge, dived into the canal like a slim, naked, sea nymph. Her head broke water a dozen feet out creating phosphorescent ripples. Jupiter plunged after her. The water was black, cold, salty. He kept up with the girl easily using strong breast strokes. At length she paused again, treading water near the opposite wall of the aquaduct. "There's a tunnel here, a man's height below the surface. It leads into another chamber. Are you willing to try it?" "Go ahead." Tabak up-ended in a surface dive, the black water closing over her feet. Jupiter followed her down. He found the hole with his hand, swam into it. On and on--ten--twenty--thirty yards. His lungs felt as if they must burst. Air began to dribble out his nose. He kicked furiously, driving himself ahead. Suddenly he realized he was out of the tunnel. He shot up to the surface, broke water, gasping air into his scalded lungs. That had been close, too close. He floated on his back breathing deeply. After a minute he rolled over and stared about him. * * * * * He was in a vast echoing chamber. Orange sunshine streamed in from open skylights. Steps led down into the water. Tabak, he saw, was already standing on the edge of the floor looking down at him. He swam to the steps, climbed out. There was a faint odor of putrefaction in the air. Tabak said: "These rooms are the laboratories. There are other entrances; but they're all guarded by Nehogans." He frowned. "What was it you wanted me to see?"
