Cascade Point

"Not in detail, but the settings look all right to me."

"They did to me, too, but if there's any chance the computer's developed problems we can't take anything for granted. I don't want to be in the wrong position when it's time for the next point."

"Yeah. Well, Pascal's due up here in ten minutes. I guess the astrogate deep- check can wait until then. What did you find out from Lanton?"

With an effort I switched gears. "According to him, Bradley's not going to be any trouble. He sounds more neurotic than psychotic, from Lanton's description, at least at the moment. Unfortunately, Lanton's got this great plan to use cascade images as a research tool, and intends to keep Bradley awake through every point between here and Taimyr."

"He what? I don't suppose he's bothered to consider what that might do to Bradley's problems?"

"That's what I wanted to know. I never did get an acceptable answer." I moved to the bridge door, poked the release. "Don't worry, we'll pound some sense into him before the next point. See you later."

Wilkinson and Sarojis were both in the number one hold when I arrived, Sarojis offering minor assistance and lots of suggestions as Wilkinson crawled over the shimmery metal box that took up the forward third of the narrow space. Looking down at me as I threaded my way between the other boxes cramming the hold, he shook his head. "Nothing wrong here, Cap'n," he said. "The shields structurally sound; there's no way the Ming metal inside could affect our configuration."

"No chance of hairline cracks?" I asked.

He held up the detector he'd been using. "I'm checking, but nothing that small would do anything."

I nodded acknowledgement and spent a moment frowning at the box. Ming metal had a number of unique properties inside cascade points, properties that made it both a blessing and a curse to those of us who had to fly with it. Its unique blessing, of course, was that its electrical, magnetic, and thermodynamic properties were affected only by the absolute angle the ship rotated through, and not by any of the hundred or so other variables in a given cascade maneuver. It was this predictability that finally had made it possible for a cascade point autodrive mechanism to be developed. Of more concern to smaller ships like mine, though, was that Ming metal drastically changed a ship's "configuration"—the size, shape, velocity profile, and so on from which the relation between rotation angle and distance traveled on a given maneuver could be computed. Fortunately, the effect was somewhat analogous to air resistance, in that if one piece of Ming metal were completely enclosed in another, only the outer container's shape, size, and mass would affect the configuration. Hence, the shield. But if it hadn't been breached, then the cargo inside it couldn't have fouled us up.... "What are the chances," I asked Wilkinson, "that one of these other boxes contains Ming metal?"

"Without listing it on the manifest?" Sarojis piped up indignantly. He was a dark, intense little man who always seemed loudly astonished whenever anyone did anything either unjust or stupid. Most everyone on the Dancer OD'd periodically on his chatter and spent every third day or so avoiding him. Alana and Wilkinson were the only exceptions I knew of, and even Alana got tired of him every so often. "They couldn't do that," Sarojis continued before I could respond. "We could sue them into bankruptcy."

"Only if we make it to Taimyr," I said briefly, my eyes on Wilkinson.

"One way to find out," he returned. Dropping lightly off the shield, he replaced his detector in the open tool box lying on the deck and withdrew a wandlike gadget.

It took two hours to run the wand over every crate in the Dancer's three holds, and we came up with precisely nothing. "Maybe one of the passengers brought some aboard," Sarojis suggested.

"You've got to be richer than any of our customers to buy cases with Ming- metal buckles." Wilkinson shook his head. "Cap'n, it's got to be a computer fault, or else something in the gyro."

"Um," I said noncommittally. I hadn't yet told them that I'd checked with Alana midway through all the cargo testing and that she and Pascal had found nothing wrong in their deep-checks of both systems. There was no point in worrying them more than necessary.

I returned to the bridge to find Pascal there alone, slouching in the helm chair and gazing at the displays with a dreamy sort of expression on his face. "Where's Alana?" I asked him, dropping into the other chair and eyeing the pile of diagnostic printouts they'd thoughtfully left for me. "Finally gone to bed?"

"She said she was going to stop by the dining room first and have some di

I glanced at my watch, realizing with a start that it was indeed di

He shook his head. "I have a theory about the cascade point error," he said, lowering his voice conspiratorially. "I'd rather not say what it is, though, until I've had more time to think about it."

"Sure," I said, and left. Pascal fancied himself a great scientific detective and was always coming up with complex and wholly unrealistic theories in areas far outside his field, with predictable results. Still, nothing he'd ever come up with had been actually dangerous, and there was always the chance he would someday hit on something useful. I hoped this would be the day.

The Dancer's compact dining room was surprisingly crowded for so soon after the first cascade point, but a quick scan of the faces showed me why. Only nine of our twelve passengers had made it out of bed after their first experience with sleepers, but their absence was more than made up for by the six crewers who had opted to eat here tonight instead of in the duty mess. The entire off-duty contingent... and it wasn't hard to figure out why.

Bradley, seated between Lanton and Tobbar at one of the two tables, was speaking earnestly as I slipped through the door. "...less symbolic than it was an attempt to portray the world from a truly alien viewpoint, a viewpoint he would change every few years. Thus A Midsummer Wedding has both the slight fish-eye distortion and the color shifts you might get from a water-dwelling creature; also the subtleties of posture and expression that such an alien wouldn't understand and might therefore not get right."

"But isn't strange sensory expression one of the basic foundations of art?" That was Tobbar—so glib on any topic that you were never quite sure whether he actually knew anything about it or not. "Drawing both eyes on one side of the head, putting nudes at otherwise normal picnics—that sort of thing."

"True, but you mustn't confuse weirdness for its own sake with the consistent, scientifically accurate variations Meyerhaus used."

There was more, but just then Alana caught my eye from her place at the other table and indicated the empty seat next to her. I went over and sat down, losing the train of Bradley's monologue in the process. "Anything?" she whispered to me.

"A very flat zero," I told her.

She nodded once but didn't say anything, and I noticed her gaze drift back to Bradley. "Knows a lot about art, I see," I commented, oddly irritated by her shift in attention.

"You missed his talk on history," she said. "He got quite a discussion going over there—that mathematician, Dr. Chileogu, also seems to be a history buff. First time I've ever seen Tobbar completely frozen out of a discussion. He certainly seems normal enough."

"Tobbar?"

"Bradley."

"Oh." I looked over at Bradley, who was now listening intently to someone holding forth from the other end of his table. Permanently disoriented, Lanton had described him. Was he envisioning himself a professor of art or something right now? Or were his delusions that complete? I didn't know; and at the moment I didn't care. "Well, good for him. Now if you'd care to bring your mind back to ship's business, we still have a problem on our hands."
