“I’ve looked at some of the equipment,” Mellia said. “Temporal gear, but not exactly like anything I’ve seen.” Her tone suggested that meant something important. I tried to focus my brain and figure out what.
I said, “Oh.”
“I could deduce the function of some of it,” she said. “Some was completely baffling.”
“Maybe it’s Third Era stuff—”
“I’d recognize that.”
“Let’s take a look.” I headed toward the big controller’s chair, trying to look healthier than I felt. If the jump had affected Mellia at all, she didn’t show it.
The console was covered with buttons labeled laconically with designations such as M. Ds—H and LV 3—gn. The screens were the usual milky-glass anti-glare surfaces, set inside and anti-reflecting frames.
“They’re ordinary analog-potential readout boards, of course,” Mellia said, “but with two extra banks of controls—and that implies at least an additional order of sensitivity in the discretion and weighing circuitry.”
“Does it?”
“Certainly.” Her slim finger reached past me, tapped out a swift code on the colored keys. The screen twinkled and snapped to brightness.
“The pickup field is on active phase—or should be,” she said. “But there’s no base reading. And I’m afraid to play with a Timecast keybank I don’t understand.”
“You’ve left me in the shade,” I said. “I never saw anything like this stuff. What else is there?”
“There are rooms back there.” She pointed to the end of the hall opposite the glass wall. “Equipment rooms; a power section, operations…”
“Sounds like a regulation Timecasting station.”
She nodded. “Almost.”
“A little on the large side,” I commented. “Let’s take a look.”
We went through rooms packed with gear as mysterious to me as a wiring diagram to I-Em Hotep. One contained nothing but three full-length mirrors; our reflections looking back at us were a couple of forlorn strangers. Nowhere were there any indications of recent habitation. No people, no signs of people. Just a dead building full of echoes.
We recrossed the grand hall and found an exit vestibule that cycled us out onto a wide stone terrace above a familiar view of sand and sea. The curve of the shoreline was as I had seen it last; only the jungle growth on the headland seemed denser, more solid somehow.
“Good old Dinosaur Beach,” I said. “Doesn’t change much, does it?”
“Time has passed,” Mellia said. “A great deal of time.”
“There was nothing like this in any projection plan I ever saw,” I said. “Any ideas?”
“Not that I want to verbalize.”
“I know how you feel,” I said, and held the door for her. “By the way: I ought to tell you: I never heard of analog-potential. What is it, a new kind of breakfast food?”
“A-P is the basis of the entire Timesweep program,” she said and looked at me sharply. “Any Nexx agent would have to be familiar with it.” She was frowning at me pretty severely.
“Don’t count on it,” I said. “The lectures I got at the Institute were all about deterministics, actualization dynamics, and fixation levels.”
“That’s nonsense. Discredited Fatalistics Theory.”
“Hold on, Miss Gayl, before you pop a valve. Don’t look at me as if you’d caught me in the computer room with a live bomb. I admit I’m a little slow this morning, what with the heavy swell under the stern quarter, but I’m still the same sweet, lovable guy you fished out of the pond. I’m as much a Nexxman as you are; but a kind of dirty suspicion is sneaking up on me.”
“And what might that be?”
“That the Nexx Central you work out of and the one I know aren’t the same.”
“That’s ridiculous. The entire Nexx operation is based on the stability of the unique Nexx Baseline—”
“Sure—that’s the concept. It won’t be the first concept that had to be modified in the face of experience.”
She looked a little pale. “You realize what you’re implying?”
“Uh-huh. We’ve messed things up good, kid. For you and me to be standing here face to face—representatives of two mutually exclusive base timetracks—means things are worse than we thought; worse than I knew they could be.”
Her eyes held on mine, wide and shocked. I was doing a good job of reassuring her.
“But we’re not licked yet,” I said heartily. “We’re still trained agents, still operational. We’ll do the best we can—”
“That’s not the point.”
“Oh? What is?”
“We have a job to do—as you said: to attempt to reintroduce ourselves into the temporal pattern by eliminating the chronomalies we’ve unwittingly generated.”
“Agreed.”
“Very well—what pattern do we work toward, Ravel? Yours—or mine? It is a Deterministic or an A-P continuum we’re supposed to be reassembling?”
I started to give her a fast, reassuring answer, but it stuck in my throat.
“We can work that out later,” I said.
“How can we? Every move we make from this point on has to be correctly calculated. There’s equipment here—” she waved a hand—“that’s more sophisticated than anything I’ve ever seen. But we have to use it properly.”
“Sure we do—but first we have to figure out what all the pretty little buttons are for. Let’s concentrate on that for the present, Mellia. Maybe along the way we can resolve the philosophical questions.”
“Before we can work together, we have to come to some agreement.”
“Go on.”
“I want your word you won’t … do anything prejudicial to the A-P concept.”
“I won’t do anything without conferring with you first. As to what Universe it is we’re rebuilding—let’s wait until we know a little more before we commit ourselves, all right?”
She looked at me a long time before she said, “Very well.”
“You might start,” I said, “by explaining this setup to me.”
She spent the next hour giving me a fast, sketchy, but graphic briefing on the art of analog-potential interpretation; I listened as fast as I could. The A-P theory was news to me, but I was accustomed to working with complex chronic gear. I began to get some idea of what the equipment was for.
“I get the feeling that your version of Nexx Central operates a lot farther out in the theoretical boondocks than the one I know,” I said. “And backs it up with some very highly evolved hardware.”
“Of course, what I’m accustomed to is much less advanced than this,” Mellia said. “I don’t know what to make of a lot of this.”
“But you’re sure it’s A-P type gear?”
“There’s no doubt in my mind at all. It couldn’t be anything else—certainly not anything that Deterministic theory might have given rise to.”
“I agree with that last point. This layout would make about as much sense at Central—my Central—as a steam whistle on a sailboat.”
“Then you agree we have to work toward an A-P matrix?”
“Slow down, girl. You talk as if all we had to do was shake hands on it, and everything would switch back to where it was last Wednesday at three o’clock. We’re working in the blind. We don’t know what’s happened, where we are, where we’re going, or how to get there. Let’s take it one item at a time. A good place to start would be this whole A-P concept. I get a strange feeling that its theoretical basis is a second-generation type of thing; that it arises from the kind of observational foundation generated by a major temporal realignment.”
“Would you mind clarifying that?” she said coldly. I waved a hand. “Your Central isn’t on the main timestem. It’s too complex, too artificial. It’s like a star with a large heavy-element content: it can’t arise from the primordial dust cloud. It has to be formed out of stellar debris from a previous generation.”
“That’s a rather fanciful analogy. Is that the best you can do?”
“On such short notice. Or would you rather have me suppress anything that seems to cast doubts on your A-P universe as the best of all possible worlds?”
“That’s unfair.”
“Is it? I’ve got a stake in my past, too, Miss Gayl. I’m not any more eager to be relegated to the realms of unrealized possibilities than anybody else.”
“I … I didn’t mean that. What makes you think—there’s no reason to believe—”
“I have a funny feeling there’s no place for me in your world-picture, Mellia. Your original world-picture, that is. I’m the guy who loused up the sweet serenity of Dinosaur Beach. But for me, the old outfit would have been in operation for another thousand years at the same address.”
She started to say something, but I steam-rollered it.
“But it wasn’t. I fouled up my assignment—don’t ask me how—and as a result, blew the station to Kingdom Come—or wherever it disappeared to—”
“You don’t need to blame yourself. You carried out your instructions; it wasn’t your fault if the results… if after you came back…”
“Yeah. If what I did started a causal chain that resulted in your not being born. But you were born, L—Mellia. I met you on a cover assignment in 1936. So at that point, at least, we were on the same track. Or—” I cut it off there, but she saw the same thing I did.
