"Jump!" he called to Reiloc. "I've Tabak."

"By the Radiant God!" came the Nehogan's hoarse voice; "here I come!"

There was a splash, followed almost immediately by another, as the cave girl leaped also. The pair of them came up, blowing, unhurt.

"Which way?" Reiloc gasped.

"Follow the wall." Jupiter was trying to recall Tabak's memory patterns. "We're near the edge of the city, I think. There should be a beach just ahead."

They swam on, guiding themselves by the lap of water against the base of the wall. Jupiter, with his arm across Tabak's shoulder and breast, felt the girl shudder.

"Jupiter," she said weakly. "Jupiter, is that you?"

"Yes. Are you all right?"

"I—I think so. I can swim now."

All at once, he realized that the lapping of the water had changed to a faint, shushing sound.
