Falling upon all fours, like a great, misshapen pet, he waddled awkwardly after his host.

Negu Mah led him to an elevator within the house. This took them to a higher floor, and there they followed a corridor to the rear of the building. Here Negu Mah, without showing a light, opened a door, and in silence they moved out upon a small balcony overlooking the rear gardens, which were shrouded in darkness because rising Jupiter was on the opposite side of the building.

They had stood there only a moment when below them a door opened, and a small figure slipped through. Another figure appeared from beneath the shadows of a cluster of slender, purple neklo trees and moved forward to greet the first. They met in the center of a tiny open space, where a fountain spurting through holes in crystal made a sweet murmuring music. And to the two watchers rose whispered words--"Nanlo! Nanlo, my darling!" "Hugh! Oh, Hugh, my love, hold me close and tell me that everything is ready for us to leave!"

Hugh Neils' arms held her close, and his lips were hot on hers. That he was here as they had planned meant that he had succeeded in the other plans they had agreed upon. Exultation soared higher in Nanlo's breast.

"Then we can go? Go now?" she asked eagerly, as Hugh Neils released her. "The crew is asleep? You were able to arrange it?"

The young engineer looked down at her, his thin face a pale blur in the darkness.

"In five minutes, just five minutes, Nanlo, my own," he whispered. "I left the guard half an hour ago, drinking molkai into which I put a sleeping powder. Give him five more minutes to fall asleep, then we can go to the ship unseen, unchecked. Until then, we can wait here in the garden."

He led her toward the trilling fountain and they sat down upon a bench before it, of rare Callisto crystal. They still were in darkness, but the flame-like Jupiter light touched the tops of the neklo trees above them with a ruddy light which brought faint glimmerings from the radioactive leaves.

Hugh Neils was a recent college graduate whom Negu Mah had hired as an assistant supervisor in the refining mills on Callisto, where the precious uranium 235 was separated from the ordinary metal. It was not a desirable job, but the best Hugh Neils could get. His college record of reckless scrapes and entanglements with women had been against him. Indeed, this position had only come to him because his home was in the same section as Nanlo's, and Negu Mah had thought that perhaps his company on occasion would help alleviate Nanlo's restlessness.

It had--but to an extent Negu Mah had not foreseen.

"In less than a quarter of an hour, Nanlo my darling," Hugh Neils whispered now, "we'll be gone from here, and you'll belong only to me. We'll leave this infernal barren satellite to spin itself dizzy out here in no place. We'll leave that humpty-dumpty husband of yours and his hypocritical good-nature to whistle for his wife and his ship.
