"These might be looked into," said Holmes. He stuffed his pockets. The hand-weapons had barrels and handgrips and triggers. They were made to shoot, somehow. "I think--" began Pam again. "Don't," growled Holmes. "Maybe Sandy remembers when this place was different, but I've had enough of it as it is. Let's go back to the ship and some fresh air." "But that's what--" Holmes turned away. Like the rest, he'd accepted great age, mentally, as a part of the nature of the fortress. But the collapse of emptied shipping-cases because they were touched was a shock. Where such decay existed, one could not hope to find anything useful for a modern emergency. He vanished. Pam was indignant. She turned to Sandy. "I wanted to say that I smelled fresh air," she protested. "And he acts like that!" Sandy was not listening. She frowned. "He could lose his way down here," she said shortly. "We'd better keep him in sight. I remember the way from my dream." They followed Holmes, who did make his way back to the upper levels and ultimately to the ship without guidance. But Pam was intensely indignant. "We could have gotten lost down there!" she said angrily when they were back in familiar territory. "And he wouldn't have cared! And I did smell fresh air! Not very fresh, but fresher than the aged and dried-out stuff we're breathing now!" "You couldn't," said Sandy practically. "There simply couldn't be any, except in the ship where the hydroponic wall-gardens keep it fresh." "But I did!" insisted Pam. Sandy shrugged. They went into the ship, which Holmes had already reached and where he sat gloomily beside a black cube. He would have to sleep to get anything from it. There were only two of the freakish-seeming metal caps which made the cubes intelligible to a man awake, and Burke and Keller were using them. Holmes felt offended. Sandy looked at a clock and began to prepare a meal. Pam, brooding, helped her. Burke and Keller came back to the ship together. Keller looked pale. Burke seemed utterly grim. "There's some stuff to be coded and sent back to Earth," he told Sandy. "Keller's got it written out. We know how to work the instruments up above, now. My brain's reeling a little, but I think I'll stay sane. Keller takes it in stride. And we know the trick the Enemy has." Sandy put out plates for five. "What is it?"
