  Y. E. Reuther, Ch. A ccl.

  I called Reuther and thanked him and told him that I had all I wanted. I knew now that my assignment to Ricky had never been effective. Since the transfer of my stock that did show in the record was clearly fraudulent, the deal whiffed of Belle; this third party could have been either another of her stooges or possibly a fictitious person-she was probably already planning on swindling Miles by then.

  Apparently she had been short of cash after Miles's death and had sold off the smaller block. But I did not care what had happened to any of the stock once it passed out of Belle's control. I had forgotten to ask Reuther to trace Miles's stock... that might give a lead to Ricky even though she no longer held it. But it was late Friday already; I'd ask him Monday. Right now I wanted to open the large envelope still waiting for me, for I had spotted the return address.

  I had written to the patent office early in March about the original patents on both Eager Beaver and Drafting Dan. My conviction that the original Eager Beaver was just another name for Flexible Frank had been somewhat shaken by my first upsetting experience with Drafting Dan; I had considered the possibility that the same unknown genius who had conceived Dan so nearly as I had imagined him might also have developed a parallel equivalent of Flexible Frank. The theory was bulwarked by the fact that both patents had been taken out the same year and both patents were held (or had been held until they expired) by the same company, Aladdin.

  But I had to know. And if this inventor was still alive I wanted to meet him. He could teach me a thing or four.

  I had written first to the patent office, only to get a form letter back that all records of expired patents were now kept in the National Archives in Carlsbad Caverns. So I wrote the Archives and got another form letter with a schedule of fees. So I wrote a third time, sending a postal order (no personal checks, please) for prints of the whole works on both patents-descriptions, claims, drawings, histories.

  This fat envelope looked like my answer.

  The one on top was 4,307,909, the basic for Eager Beaver. I turned to the drawings, ignoring for the moment both description and claims. Claims aren't important anyway except in court; the basic notion in writing up claims on an application for patent is to claim the whole wide world in the broadest possible terms, then let the patent examiners chew you down-this is why patent attorneys are born. The descriptions, on the other hand, have to be factual, but I can read drawings faster than I can read descriptions.

  I had to admit that it did not look too much like Flexible Frank. It was better than Flexible Frank; it could do more and some of the linkages were simpler. The basic notion was the same-but that had to be true, as a machine controlled by Thorsen tubes and ancestral to Eager Beaver had to be based on the same principles I had used in Flexible Frank.

  I could almost see myself developing just such a device sort of a second-stage model of Frank, I had once had something of the sort in mind-Frank without Frank's household limitations.

  I finally got around to looking up the inventor's name on the claims and description sheets.

  I recognized it all right. It was D. B. Davis.

  I looked at it while whistling "Time on My Hands" slowly and off key. So Belle had lied again. I wondered if there was any truth at all in that spate of drivel she had fed me. Of course Belle was a pathological liar, but I had read somewhere that pathological liars usually have a pattern, starting from the truth and embellishing it, rather than indulging in complete fancy. Quite evidently my model of Frank had never been "stolen" but had been turned over to some other engineer to smooth up, then the application had been made in my name.

  But the Mannix deal had never gone through; that one fact was certain, since I knew it from company records. But Belle had said that their failure to produce Flexible Frank as contracted had soured the Mannix deal.

  Had Miles grabbed Frank for himself, letting Belle think that it had been stolen? Or restolen, rather.

  In that case... I dropped guessing at it, as hopeless, more hopeless than the search for Ricky. I might have to take a job with Aladdin before I would be able to ferret out where they had gotten the basic patent and who had benefited by the deal. It probably was not worth it, since the patent was expired, Miles was dead, and Belle, if she had gained a dime out of it, had long since thrown it away. I had satisfied myself on the one point important to me, the thing I had set out to prove; i.e., that I myself was the original inventor. My professional pride was salved and who cares about money when three meals a day are taken care of? Not me.

  So I turned to 4,307,910, the first Drafting Dan.

  The drawings were a delight. I couldn't have planned it better myself; this boy really had it. I admired the economy of the linkages and the clever way the circuits had been used to reduce the moving parts to a minimum. Moving parts are like the vermiform appendix; a source of trouble to be done away with whenever possible.

  He had even used an electric typewriter for his keyboard chassis, giving credit on the drawing to an IBM patent series. That was smart, that was engineering: never reinvent something that you can buy down the street.

  I had to know who this brainy boy was, so I turned to the papers.

  It was D. B. Davis.

  After quite a long time I phoned Dr. Albrecht. They rounded him up and I told him who I was, since my office phone had no visual.

  "I recognized your voice," he answered. "Hi, there, son. How are you getting along with your new job?"

  "Well enough. They haven't offered me a partnership yet."

  "Give them time. Happy otherwise? Find yourself fitting back in?"

  "Oh, sure! If I had known what a great place here and now is I'd have taken the Sleep earlier. You couldn't hire me to go back to 1970."

  "Oh, come now! I remember that year pretty well. I was a kid then on a farm in Nebraska. I used to hunt and fish. I had fun. More than I have now."

  "Well, to each his own. I like it now. But look, Doc, I didn't call up just to talk philosophy; I've got a little problem."

  "Well, let's have it. It ought to be a relief; most people have big problems."

  "Doc? Is it at all possible for the Long Sleep to cause amnesia?"

  He hesitated before replying. "It is conceivably possible. I can't say that I've ever seen a case, as such. 1 mean unconnected with other causes."

  "What are the things that cause amnesia?"

  "Any number of things. The commonest, perhaps, is the patient's own subconscious wish. He forgets a sequence of events, or rearranges them, because the facts are unbearable to him. That's a functional amnesia in the raw. Then there is the old-fashioned knock on the head-amnesia from trauma. Or it might be amnesia through suggestion... under drugs or hypnosis. What's the matter, bub? Can't you find your checkbook?"

  "It's not that. So far as I know, I'm getting along just fine now. But I can't get some things straight that happened before I took the Sleep... and it's got me worried."

  "Mmm ... any possibility of any of the causes I mentioned?"

  "Yes," I said slowly. "Uh, all of them, except maybe the bump on the head... and even that might have happened while I was drunk."

  "I neglected to mention," he said dryly, "the commonest temporary amnesia-pulling a blank while under the affluence of alcohol. See here, son, why don't you come see me and we'll talk it over in detail? If I can't tag what is biting you-I'm not a psychiatrist, you know-I can turn you over to a hypno-analyst who will peel back your memory like an onion and tell you why you were late to school on the fourth of February your second-grade year. But he's pretty expensive, so why not give me a whirl first?"

  I said, "Cripes, Doe, I've bothered you too much already and you are pretty stuffy about taking money."

  "Son, I'm always interested in my people; they're all the family I have."

  So I put him off by saying that I would call him the first of the we
ek if I wasn't straightened out. I wanted to think about it anyhow.

  Most of the lights went out except in my office; a Hired Girl, scrubwoman type, looked in, twigged that the room was still occupied, and rolled silently away. I still sat there.

  Presently Chuck Freudenberg stuck his head in and said, "I thought you left long ago. Wake up and finish your sleep at home."

  I looked up. "Chuck, I've got a wonderful idea. Let's buy a barrel of beer and two straws."

  He considered it carefully. "Well, it's Friday ... and I always like to have a head on Monday; it lets me know what day it is."

  "Carried and so ordered. Wait a second while I stuff some things in this brief case."

  We had some beers, then we had some food, then we had more beers at a place where the music was good, then we moved on to another place where there was no music and the booths had hush linings and they didn't disturb you as long as you ordered something about once an hour. We talked. I showed him the patent records.

  Chuck looked over the Eager Beaver prototype. "That's a real nice job, Dan. I'm proud of you, boy. I'd like your autograph."

  "But look at this one." I gave him the drafting-machine patent papers.

  "Some ways this one is even nicer. Dan, do you realize that you have probably had more influence on the present state of the art than, well, than Edison had in his period? You know that, boy?"

  "Cut it out, Chuck; this is serious." I gestured abruptly at the pile of photostats. "Okay, so I'm responsible for one of them. But I can't be responsible for the other one. I didn't do it... unless I'm completely mixed up about my own life before I took the Sleep. Unless I've got amnesia."

  "You've been saying that for the past twenty minutes. But you don't seem to have any open circuits. You're no cra2ier than is normal in an engineer."

  I banged the table, making the stems dance. "I've got to know!"

  "Steady there. So what are you going to do?"

  "Huh?" I pondered it. "I'm going to pay a psychiatrist to dig it out of me."

  He sighed. "I thought you might say that. Now look, Dan, let's suppose you pay this brain mechanic to do this and he reports that nothing is wrong, your memory is in fine shape, and all your relays are closed. What then?"

  "That's impossible."

  "That's what they told Columbus. You haven't even mentioned the most likely explanation."

  "Huh? What?"

  Without answering he signaled the waiter and told it to bring back the big phone book, extended area. I said, "What's the matter? You calling the wagon for me?"

  "Not yet." He thumbed through the enormous book, then stopped and said, "Dan, scan this."

  I looked. He had his finger on "Davis." There were columns of Davises. But where he had his finger there were a dozen "D. B. Davises"-from "Dabney" to "Duncan."

  There were three "Daniel B. Davises." One of them was me.

  "That's from less than seven million people," he pointed out. "Want to try your luck on more than two hundred and fifty million?"

  "It doesn't prove anything," I said feebly.

  "No," he agreed, "it doesn't. It would be quite a coincidence, I readily agree, if two engineers with such similar talents happened to be working on the same sort of thing at the same time and just happened to have the same last name and the same initials. By the laws of statistics we could probably approximate just how unlikely it is that it would happen. But people forget-especially those who ought to know better, such as yourself-that while the laws of statistics tell you how unlikely a particular coincidence is, they state just as firmly that coincidences do happen. This looks like one. I like that a lot better than I like the theory that my beer buddy has slipped his cams. Good beer buddies are hard to come by."

  "What do you think I ought to do?"

  "The first thing to do is not to waste your time and money on a psychiatrist until you try the second thing. The second thing is to find out the first name of this `D. B. Davis' who filed this patent. There will be some easy way to do that. Likely as not his first name will be `Dexter.' Or even `Dorothy.' But don't trip a breaker if it is `Daniel,' because the middle name might be `Berzowski' with a social-security number different from yours. And the third thing to do, which is really the first, is to forget it for now and order another round."

  So we did, and talked of other things, particularly women. Chuck had a theory that women were closely related to machinery, but utterly unpredictable by logic. He drew graphs on the table top in beer to prove his thesis.

  Sometime later I said suddenly, "If there were real time travel, I know what I would do."

  "Huh? What are you talking about?"

  "About my problem. Look, Chuck, I got here-got to `now' I mean-by a sort of half-baked, horse-and-buggy time travel. But the trouble is I can't go back. All the things that are worrying me happened thirty years ago. I'd go back and dig out the truth if there were such a thing as real time travel." He stared at me. "But there is."

  "What?"

  He suddenly sobered. "I shouldn't have said that."

  I said, "Maybe not, but you already have said it. Now you'd better tell me what you mean before I empty this here stein over your head."

  "Forget it, Dan. I made a slip."

  "Talk!"

  "That's just what I can't do." He glanced around. No one was near us. "It's classified."

  "Time travel classified? Good God, why?"

  "Hell, boy, didn't you ever work for the government? They'd classify sex if they could. There doesn't have to be a reason; it's just their policy. But it is classified and I'm bound by it. So lay off."

  "But-Quit fooling around about it, Chuck; this is important to me. Terribly important." When he didn't answer and looked stubborn I said, "You can tell me. Shucks, I used to have a 'Q' clearance myself. Never suspended, either. It's just that I'm no longer with the government."

  "What's a `Q' clearance?"

  I explained and presently he nodded. "You mean an `Alpha' status. You must have been hot stuff, boy; I only rated a `Beta.'"

  "Then why can't you tell me?"

  "Huh? You know why. Regardless of your rated status, you don't have the necessary `Need to Know' qualification."

  "The hell I don't! `Need to Know' is what I've got most of."

  But he wouldn't budge, so finally I said in disgust, "I don't think there is such a thing. I think you just had a belch back up on you."

  He stared at me solemnly for a while, then he said, "Danny."

  "Huh?"

  "I'm going to tell you. Just remember your `Alpha' status, boy. I'm going to tell you because it can't hurt anything and I want you to realize that it couldn't possibly be of use to you in your problem. It's time travel, all right, but it's not practical. You can't use it."

  "Why not?"

  "Give me a chance, will you? They never smoothed the bugs out of it and it's not even theoretically possible that they ever will. It's of no practical value whatsoever, even for research. It's a mere by-product of NullGrav-that's why they classified it."

  "But, hell, NullGrav is declassified."

  "What's that got to do with it? If this was commercial, too, maybe they'd unwrap it. But shut up."

  I'm afraid I didn't, but I'd rather tell this as if I had. During Chuck's senior year at the University of Colorado-Boulder, that is-he had earned extra money as a lab assistant. They had a big cryogenics lab there and at first he had worked in that. But the school had a juicy defense contract concerned with the Edinburgh field theory and they had built a big new physics laboratory in the mountains out of town. Chuck was reassigned there to Professor Twitchell-Dr. Hubert Twitchell, the man who just missed the Nobel Prize and got nasty about it.

  "Twitch got the notion that if he polarized around another axis he could reverse the gravitational field instead of leveling it off. Nothing happened. So he fed what he had done back into the computer and got wild-eyed at the results. He never showed them to me, of course. He put two silver dollars into the test cageÄth
ey still used hard money around those parts then-after making me mark them. He punched the solenoid button and they disappeared.

  "Now that is not much of a trick," Chuck went on. `Properly, he should have followed up by making them reappear out of the nose of a little boy who volunteers to come up on the stage. But he seemed satisfied, so I was-I was paid by the hour.

  "A week later one of those cartwheels reappeared. Just one. But before that, one afternoon while I was cleaning up after he had gone home, a guinea pig showed up in the cage. It didn't belong in the lab and I hadn't seen it around before, so I took it over to the bio lab on my way home. They counted and weren't short any pigs, although it's hard to be certain with guinea pigs, so I took it home and made a pet out of it.

  "After that single silver dollar came back Twitch got so worked up he quit shaving. Next time he used two guinea pigs from the bio lab. One of them looked awfully familiar to me, but I didn't see it long because he pushed the panic button and they both disappeared.

  "When one of them came back about ten days later-the one that didn't look like mine-Twitch knew for sure he had it. Then the resident 0-in-C for the department of defense came around-a chair-type colonel who used to be a professor himself, of botany. Very military type... Twitch had no use for him. This colonel swore us both to double-dyed secrecy, over and above our `status' oaths. He seemed to think that he had the greatest thing in military logistics since Caesar invented the carbon copy. His idea was that you could send divisions forward or back to a battle you had lost, or were going to lose, and save the day. The enemy would never figure out what had happened. He was crazy in hearts and spades, of course... and he didn't get the star he was bucking for. But the `Critically Secret' classification he stuck on it stayed, so far as I know, right up to the present. I've never seen a disclosure on it."

  "It might have some military use," I argued, "it seems to me, if you could engineer it to take a division of soldiers at a time. No, wait a minute. I see the hitch. You always had `em paired. It would take two divisions, one to go forward, one to go back. One division you would lose entirely... I suppose it would be more practical to have a division at the right time in the first place."
