to safety. It was dark again, as if, after that brief glimpse of dawn, the night had returned with redoubled gloom.
Now the men were starting to go - Baldur first, probably blessing his position in the alphabet. There were only a dozen left in the cabin when the barricaded door finally ripped from its hinges, and the pent-up avalanche burst forth.
The first wave of dust caught Pat while he was halfway up the slope of the cabin. Light and impalpable though it was, it slowed his movements until it seemed that he was struggling to wade through glue. It was fortunate that the moist and heavy air had robbed it of some of its power, for otherwise it would have filled the cabin with choking clouds. Pat sneezed and coughed and was partly blinded, but he could still breathe.
In the foggy gloom he could hear Sue counting - "Fifteen, sixteen, seventeen, eighteen, nineteen - " as she marshaled the passengers to safety. He had intended her to go with the other women, but she was still down here, shepherding her charges. Even as he struggled against the cloying quicksand that had now risen almost to his waist, he felt for Sue a love so great that it seemed to burst his heart. Now he had no possible doubt. Real love was a perfect balance of desire and tenderness. The first had been there for a long time, and now the second had come in full measure.
"Twenty - that's you, Commodore - quickly!"
"Like hell it is, Sue," said the Commodore. "Up you go."
Pat could not see what happened - he was still partly blinded by the dust and the darkness - but he guessed that Hansteen must have literally thrown Sue through the roof. Neither his age nor his years in space had yet robbed him of his Earthborn strength.
"Are you there, Pat?" he called. "I'm on the ladder."
"Don't wait for me - I'm coming."
That was easier said than done. It felt as if a million soft yet determined fingers were clutching at him, pulling him back into the rising flood. He gripped one of the seat-backs - now almost hidden beneath the dust - and pulled himself toward the beckoning light.
Something whipped against his face; instinctively, he reached out to push it aside, then realized that it was the end of the rope ladder. He hauled upon it with all his might, and slowly, reluctantly, the Sea of Thirst relaxed its grip upon him.
Before he entered the shaft, he had one last glimpse of the cabin. The whole of the rear was now submerged by that crawling tide of gray; it seemed unnatural, and doubly sinister, that it rose in such a geometrically perfect plane, without a single ripple to furrow its surface. A meter away - this was something Pat knew he would remember all his life, though he could not imagine why - a solitary paper cup was floating sedately on the rising tide, like a toy boat upon a peaceful lake. In a few minutes it would reach the ceiling and be overwhelmed, but for the moment it was still bravely defying the dust.
And so were the emergency lights; they would continue to burn for days, even when each one was encapsulated in utter darkness.
Now the dim-lit shaft was around him. He was climbing as quickly as his muscles would permit, but he could not overtake the Commodore. There was a sudden flood of light from above as Hansteen cleared the mouth of the shaft, and involuntarily Pat looked downward to protect his eyes from the glare. The dust was already rising swiftly behind him, still unrippled, still smooth and placid - and inexorable.
Then he was straddling the low mouth of the caisson, in the center of a fantastically overcrowded igloo. All around him, in various stages of exhaustion and dishevelment, were his fellow passengers; helping them were four space-suited figures and one man without a suit, whom he assumed was Chief Engineer Lawrence. How strange it was to see a new face, after all these days.
"Is everyone out?" Lawrence asked anxiously.
"Yes," said Pat. "I'm the last man." Then he added, "I hope," for he realized that in the darkness and confusion someone might have been left behind. Suppose Radley had decided not to face the music back in New Zealand -
No - he was here with the rest of them. Pat was just starting to do a count of heads when the plastic floor gave
