This time Gavin made good his escape. He had been politely instructed not to pry, he realized. Villanowski might be confident of him, but not the Captain.

Gavin was smiling when he met Nadia at the main port, but his eyes were hard. Both of them had donned outer insulating garments of thermal cloth.

"We're going to be carried in litters like ancient Oriental potentates," he informed her.

Nadia laughed. "You've never been to Jupiter before?"

He shook his head.

They passed through the lock into the swirling yellow air. It was like swimming. They crept down the gangplank. The bearers were standing patiently at the surface.

Gavin had seen Jovian dawn men before, but they never failed to excite his curiosity. Huge, almost seven feet tall, and muscled like gladiators, they were imposing as Greek gods. Their skin was the vivid blue of polished turquoise, their long manes as yellow as a sunburst.

"There's a double litter," Nadia pointed out. "Let's take that."

Gavin followed her inside. The litter was cushioned like a divan. One was borne along in a semi reclining position. Nadia clapped her hands and cried, "Cantonment!"

Four naked blue giants swung the litter to their shoulders and started off at a rapid trot. In a few paces, the ship had disappeared. They were like a tiny raft, alone in a welter of yellow oppressive fog.
