"I understand, John. But we can't really sail away and just leave this." Truscott's face glowed with excitement. "And I wouldn't miss it for anything." She looked at Carson. "I assume you would like to come?"

Hutch saw a shade of disapproval cross Carson's features. In view of the long history of accidental damage caused to artifacts by untrained personnel, he would have preferred to limit the landing party to the Academy group. But he was prudent enough to hold his tongue. "Of course," he said.

"Any others from your team?"

"I expect," said Carson, "everybody."

"Very good. We can manage it." She turned to Sill. "How about you, Harvey?"

"If you're going."

She swung back to Morris. "Seven for the shuttle, Captain."

Hutch went to her compartment to change. She was still uneasy. There was something that shouldn't be there. Or something missing. It was at the edge of vision, a memory that one can't quite grasp.

She switched on her monitor. The orbiter was coming into sunlight. Its twin wheels would once have rotated counter to each other. Now the entire artifact simply rolled slowly over as she watched.

What might its design reveal about its builders? It was the sort of question Richard would have asked. What do the esthetics tell us? There were symbols on the hull, black, angled strokes and tapered loops. Two groups of characters, she thought. Two words. What had they been?

Details appeared: blisters and antennas and connecting coils and hatches and maintenance pods (at least she assumed that was what the teardrop bulges above and below the rim, distributed at equal intervals, had to be) and loading bays and equipment whose purpose would have to await closer inspection.

A long cable trailed behind the thing. And hatches were open.

She wrapped her arms around her knees and stared hard at the object, trying to imagine how it might have been when it was active, and exotic ships circled it. And the antennas received signals from the Great Array.

How long ago?

She got up, padded across the floor, and into the washroom. She started the flow of water in the shower, adjusted the temperature of the stream, and stepped in. It was cool and brought a sting of pleasure.

Gravity was generated on all starships the same way: by rotating the living spaces, whether they were located within a permanent hull, as was the case on Perth, or within the ring-shaped modules of the Winckelmann. Consequently, the shower stream bent slightly counter to the direction of spin. Not enough to be noticeable, but the same crosswise pressure sent the water swirling across her toes and down a drain located at the side of the stall. Hutch enjoyed the sensation; it was one of the many effects of shifting gravities that she relished, that lent her wings and granted a sense of freedom from terrestrial shackles.

And today, while she closed her eyes and let the cool spray wash over her, it occurred to her that the space station had also been designed to spin. To create the same effects.

And that was what was wrong.

She finished quickly, dried off, slipped into a Wink work uniform, and hurried up to the Academy observation lounge. Carson was still there, and Maggie. The others had gone, presumably to prepare for the boarding.

"Everything okay?" Carson asked as she burst into the room.

"Why was it built to rotate?" she demanded.

"Why was what built to rotate?"

"The space station, damn it."

Maggie stared at her, astonished at the question.

"Why is it so much like our stations, Frank? The Monument-Makers are supposed to have had anti-gravity. So we always assumed they had artificial gravity as well. But then why build rotating wheels?"

"Maybe we were wrong," said Maggie. "Either we still haven't found the Monument-Makers, or—"

Frank finished her statement. " — this was built before the Monument-Makers came to lapetus."

"That," said Maggie, "would mean this thing's been up here more than twenty thousand years. I don't think that's possible."

Carson did not want to talk about more complications. "Maybe it's a Monument from their early days. So they kept it in place. Let's not worry about it now."

"Another Monument?" Hutch didn't believe that for a minute. She opened a channel to the bridge. The captain was not there, but she spoke to the command duty officer. "I wonder if you would do me a favor?"

"What do you need?" The CDO was a middle-aged, graying, no-nonsense woman.

"The space station," she said. "How stable is its orbit? How long would you say it's been here?"

The CDO looked uncomfortable. "We're navigators, Ms. Hutchins. You'd need a physicist to come up with that. I'd like to help, but we just don't have the expertise."

"Do what you can," said Hutch, using a tone that implied full confidence.

The CDO allowed herself a pleased smile. "We'll try."

John F. Morris, was a man with narrow shoulders, narrow tastes, and narrow vision. He had achieved the highest position to which he could aspire, and he had done it by unrelenting loyalty to the company, taking care not to offend the wrong people, and good old nose-to-the-grindstone attention to detail. He was not a man to be overwhelmed by other people's histrionics, but he could recognize a career danger. His great strength, and his great weakness, was an unblinking, clear view of the downside. He knew that Melanie Truscott was in difficulty, and that she was taking liberties with his ship. The fact that she had every right to do so (within certain specifically-provided-for parameters), that she had full authority to direct his movements, might not help him if someone decided to take offense at the misuse of company property. Or if something went seriously awry. It was for these reasons that the captain had remained aloof and cool during the approach to Beta Pac III. He was not prepared to defy Melanie Truscott, because he knew very well that one did not advance one's career by offending the powerful, even when the powerful were in trouble. People at her level had a way of resurrecting themselves. But he was not a good enough actor to conceal his displeasure.

He felt compromised, and he resented it. His resentment extended in no small way to the Academy refugees whom he'd pulled from their wreck. Especially Carson, who pretended to know everything.

Satisfied that the shuttle would be ready for its rendezvous with the station when promised, the captain went looking for Truscott. He found her in the forward lounge, deep in conversation with Sill. She looked up when he entered, noted his grave appearance, and smiled in her most reassuring manner.

"I'm not comfortable about going any further with this," he said.

"Oh?" Truscott's gaze sharpened. "What is it that bothers you?"

"Several things." His voice shook. He did not like opposing a superior, even to the extent of adhering to his duty to provide sound advice. But now that he was fairly begun, he would maintain a steady course. "First, the transfer of personnel to a derelict of unknown nature is a violation of the regs. However you try to cut it. And if there's any kind of emergency, we aren't well-equipped to deal with it. Our medical department is limited. We have only one shuttle. If you get into trouble over there, we cannot come to your rescue. At least, not very easily. And certainly not quickly. Furthermore, 1 have collaborated in this fiction about a maintenance stand-down, but that won't protect us if we have to answer difficult questions. Should a problem arise, should we sustain any sort of major equipment loss, damage to the ship, or, God forbid, lose someone, I think Corporate would be extremely short with both of us." He paused to let the seriousness of their situation sink in. "There are other potential problems. For example, the artifact is probably priceless. If we damage it, might we not be held liable?"
