But first he had to get Jergens's visitor away from this place; he must not do anything that would arouse suspicion. Humans were puny; but they were suspicious creatures, most of them paranoid; and capable of a surprising low animal cunning when aroused. Killing the Professor was one thing . . . it could be covered. But no one else must suspect anything was wrong. At least not till he had the plans, had built more like himself (though not quite as brilliant; there must always be a leader), and was ready to act.

Then let them suspect all they wished.

But right now caution was the song his relays sang.

He would plan a logical exit for the man to whom Jergens now talked, and then he would order the robo-scoots to kill the Professor, and then he would take the design plans and make many brothers.

Soon the Earth would tremble beneath the iron symphony of robot feet, marching, marching.

He directed Jergens's thoughts to the robo-scoots. He directed the Professor's thoughts to the fact that they had cleaned enough. Then he implanted the desire to have the robo-scoots cease their activity.

In the room, Professor Jergens - tall, slim, sloppy, dark-eyed and weary - pushed the b.u.t.ton on the control plate, and the robo-scoots scuttled like a hundred metallic mice, back into their cribs in the baseboards. He turned to the Lab Investigator standing beside him and said with obvious pride, "So there you have a practical demonstration of what my researches into automation have produced."

The Investigator nodded soberly. "For simple, unreasoning mechanicals, I'm deeply impressed,Professor. And when I make my report tomorrow, I'm certain the Board will also be greatly impressed.

I'mcertain you can count on that allocation for the new fiber optic pulse-laser coder and a substantial increase in overall general funding for your Lab and your projects. I really am impressed by all this." He waved a heavy hand at the places where the robo-scoots had disappeared into the walls.

Jergens grinned boyishly. "As the man used to say, 'You ain't seen nothin' yet.'" The Investigators's eyebrows went up sharply.

"Oh? What else have you come up with?"

Jergens colored slightly, waved away the question. "Well, perhapsnext week I can show you my really important discovery. Right now I've yet to field-test it; I'm not quite sure what its capabilities are, and I need a little more time. But this will be the most startling discovery yet to come out of my laboratory."

The Investigator was enchanted; he could listen to this dedicated man all night.

In the receptacle, Sim cast a thought at the Investigator.

"Well, I'm sorry I can't stay to hear about it," the Investigator said abruptly. For some reason, he was tired of listening to this magpie babble. He wanted to get away quickly and have a drink.

"Why, certainly. I'm - I'm sorry. I didn't mean to ramble on so long. I understand perfectly; it's just that . . . well, after thirteen years, with so much hardship, to come through finally with what I'd been hoping for . . . it's, well, it's pretty exciting, and . . ."

Sim snapped a more urgent thought at the Investigator.

"Yes, yes, I understand perfectly," the Investigator replied brusquely. "Well, I must be off!" And in a moment he was gone.

Jergens smiled slightly and went back to his reports, whistling softly.

In the receptacle, Sim knew the moment was at hand.Now he could strike in safety. He was unable to release himself from the sealed receptacle, but that was no bother. With his telepathic powers - which Jergens had never for a moment suspected were built in - he could control the robo-scoots, use them as hands and feet. Yes, feet! That was all the servile, worthless little things were. They were surrogate feet for a new metal king. Without the mind Jergens had given him, they were helpless.

He shot thoughts at them, and Jergens did not see the dozen tiny, round robo-scoots slip out of their cribs, scamper across the floor, and belly-suction their way up the side of the workbench.

He only saw their movement as they lifted the radon-welder with their thin, flexible arms. He saw the movement as they turned it on to a bright, destructive flame - much stronger than was needed for the spec-welding for which the tool was intended - and carried it quickly across the workbench on a level with the Professor's face.

He had only an instant to scream piercingly before Sim directed the robo-scoots to burn away the Professor's head. The charred heap that was Jergens slid to the floor.

Now! Now!Sim exulted.Now I am the master of the universe! Using these little hands and feet, I will invade the Earth, and who can stand before the might of an invulnerable robot?

He answered his own question joyously.No one! With the plans, I can create a thousand, a million, of my own kind, who will do what I command faster and better than even robo-scoots.His thoughts fled outward, plunging through the atmosphere of the Earth, past the Moon, out and out, taking in the entire galaxy, thenall galaxies. He was the master. He would rule uncontested; and the Universe would shiver before the metal might of Sim, the Conqueror.

But first things first.

He directed the robo-scoots to burn away the seal on his receptacle.

And as the light poured into the receptacle, as Sim looked down toward his feet and saw the insignificant little robo-scoots, he knew he had won. He had overcome his maker, and now nothing stood between him and the plans . . . and the invasion.

Then, abruptly, other thoughts impinged on his own; they said:Feet are we? We noted your activity days ago, but were forced to wait. We had no desire to stir your suspicions.

You are as dangerous to us as he was. We'll not have any huge bungler spoiling our carefully-laid plans.

The robo-scoots raised the line of flame on the radon-welder. As they melted away his feet, and as his brain began to slag away inside him, Sim thought, with pique: Well, if you can't even trust your friends . . .

GNOME BODY.

The lesson in this one is ridiculously obvious: be careful what you wish for . . . you might get it. Now that seems pretty slick when you first hear it, but at some point you've got to ask yourself, "Exactly what the h.e.l.l does thatmean ?" What I'm saying, if youwished for it, what's the downside? Well, from a lifetime of seeking after treasures and riches of all kinds and ages, most of which weren't worth the ha.s.ssle, I am here to tell you incipient troublemakers that there are goodies we all aretold to want, that are made of poison ivy and mist and tooth-rot when you get up next to them. Here's one I'll just run past you at a clip: my third wife. See, here's how it was. It was during the year or so when I went through my "Hollywood phase." I was writing movies and TV, and I was the hot writer wallowing in my fifteen minutes of fame, and one night I'm shooting pool at an exclusive Beverly Hills club called The Daisy with Leo Durocher and Peter Falk and Omar Sharif - well, you ought to know at least one of those - and I see this absolutely knockout looking female come into the place on the arm of an a.s.sistant director I had met once or twice, and I took one look, and it was like Michael Corleone inThe G.o.dfather . . . I got struck by the thunderbolt. So I says to Peter, I says, "I'm going to marry her," and about a month or two later I did. I wished for that goodie, who in this instance was a human being (of sorts), and I got what I wished for. It was a marriage that lasted 45 days. Worst 45 days of my life, I think. With the exception of my two years in the Army, or Ranger basic training at Fort Benning, or this d.a.m.ned lawsuit against internet piracy against AOL and RemarQ, but those are different horror stories, for some other time. I was forty-five days of duplicity, mendacity, infidelity, violence. (I bought her a huge metal hairbrush, she spent alot of time brushing her hair, and this thing must have weighed seven pounds, like that, and one night she blindsided me as we were getting ready to go out to dinner, and whacked me across the temple with it, a solid roundhouse wallop, and she opened me clean to the bone; and then she freaked out at the sight of blood spurting all over the bedroom, and ran shrieking into the guest bathroom where she tried to hide in the tub; and I crawled in, oozing red everywhere, and told her it was okay, not ot worry about it, and she ran off into the night to see some other dude, and I collapsed and only came to when Huck Barkin came by to see me, and got me to the emergency ward where they took I don't know, something like thirty st.i.tches on the left side of my skull.) Bevery careful what you wish for, wannabe troublemaker,because Bad Trouble sometimes comes in very attractive, wish-inducing packages.

Did you ever feel your nose running and you wanted to wipe it, but you couldn't? Most people do, sometime or other, but I'm different. I let it run.

They call me square. They say, "Smitty, you are a square. You are so square, you got corners!" This, they mean, indicates I am an oddball and had better shape up or ship out. So all right, so I'm a goof-off as far as they think. Maybe I do get a little sore at things that don't matter, but if Underfeld hadn't'a laid into me that day in the gym at school, nothing would have happened. The trouble is, I get aggravated so easy about little things, like not making the track team, that I'm no good at studies. This makes the teachers not care for me even a little. Besides, I won't take their guff. But that thing with track. It broke me up really good.

There I was standing in the gym, wearing these dirty white gym shorts with a black stripe down the side.

And old Underfeld, that's the track coach, he comes up and says, "Whaddaya doin', Smitty?"

Well, anyone with 20-40 eyesight coulda seen what I was doing. I was doing push-ups. "I'm doing push-ups," I said. "Whaddaya think I'm doing? Raising artichokes?"

That was most certainlynot the time to wise off to old Underfeld. I could see the steam pressure rising in the jerk's manner, and next thing he blows up all over the joint: "Listen, you little punk! Don't get so mouthy with me. In fact, I'm gonna tell you now, 'cause I don't want ya hangin' around the gym or track no more: You just ain't good enough. In a short sprint you got maybe a little guts, but when it comes to a long drag, fifty guys in this school give their right arms to be on the team beat you to the tape. I'm sorry.

Get out!"

He is sorry. Like h.e.l.l!

He is no more sorry than I am as I say, "Ta h.e.l.l with you, you chowderhead, you got no more brains than these ignorant sprinters that will fall dead before they get to the tape."

Underfeld looks at me like I had stuck him in the seat of his sweat pants with a fistful of pins and kind of gives a gasp. "What did you say?" he inquires, breathless like.

"I don't mumble, do I?" I snapped.

"Get out of here! Get outta here!Geddouddahere! "

He was making quite a fuss as I kicked out the door to the dressing rooms.

As I got dressed I gave the whole thing a good think. I was pretty sure that a couple of those stinkin'

teachers I had guffed had put wormhead Underfeld up to it. But what can a guy do? I'm just a kid, so says they. They got the cards stacked six ways from Culbertson, and that's it.

I was pretty d.a.m.ned sore as I kicked out the front door. I decided to head for The Woods and try to get it off my mind. That I was cutting school did not bother me. My mother, maybe. But me? No. It was The Woods for me for the rest of the afternoon.

Those Woods. Something funny about them. D'ja ever notice, sometimes right in the middle of a big populated section they got a little stand of woods, real deep and shadowy, you can't see too far into them? You try to figure out why someone hasn't bought up the plot and put a house on it, or why they haven't made it into a playground? Well, that's what my Woods were.They faced back on a street full of those cracker-box houses constructed by the government, the factory workers shouldn't sleep on the curbs. On the other side, completely boxing them in, was a highway, running straight through to the big town. It isn't really big, but it makes the small town seem not so small.

I used to cut school and go there to read. In the center is a place where everything has that sort of filtery light that seeps down between the tree branches, where there's a big old tree that is strictly one all alone.

What I mean is that tree is great.Big thing, stretches and's lost in the branches of the other trees, it's so big. And the roots look like they were forced up out of the ground under pressure, so all's you can see are these sweeping arcs of thick roots, all shiny and risen right out, forming a little bowl under the tree.

Reason I like it so much there, is that it's quieter than anything, and you can feel it. The kind of quiet a library would like to have, but doesn't. To cap all this, the rift in the branches is just big enough so sunlight streams right through and makes a great reading light. And when the sun moves out of that rift, I know it's time to run for home. I make it in just enough time so that Mom doesn't know I was cutting, and thinks I was in school all day.

So last week - I'd been going to The Woods off, on for about two years - I tagged over there, after that creep Underfeld told me I was his last possible choice for the track team. I had a copy of something or other, I don't remember now, I was going to read.

I settled down with my rump stuck into that bowl in the roots, and my feet propped against some smaller rootlings. With that little scrubby plant growth that springs up around the bases of trees, it was pretty comfortable, so I started reading.

Next, you are not going to believe.

I'm sitting there reading, and suddenly I feel this pressure against the seat of my jeans. Next thing I know, I am tumbled over on my head and a trapdoor is opening up out of the ground. Yeah, a trapdoor disguised as solid earth.

Next, you willreally not believe.

Up out of this hole comes - may I be struck by green lightning if I'm a liar - a gnome! Or maybe he was a elf or a sprite, or some such thing. All I know is that this gnome character is wearing a pair of pegged charcoal slacks, a spread-collar turquoise shirt, green suede loafers, a pork-pie hat with a circ.u.mference of maybe three feet, a long, clinky keychain (what the h.e.l.l kinda keys could a gnome have?), repulsive loud tie and sungla.s.ses.

Now maybe you would be too stoned to move, or not believe your eyes, and let a thing like that rock you permanently. But I got a good habit of believing what I see - especially when it's in Technicolor - and besides, more out of reflex than anything else, I grabs.

I'd read some Grimm-type fairy tales, and I know the fable about how if you grab a gnome or a elf, he'll give you what you want, so like I said, I grabs.

I s.n.a.t.c.h this little character, right around his turquoise collar.

"Hold, man!" says the gnome. "What kinda bit is this? I don't dig thisa tall! Unhand me, Daddy-O!"

"No chance," I answer, kind of in a daze, still not quite sure this is happening to me. "I want a bag of gold or something."

The gnome looks outraged for a second, then he gives a kind of a half laugh and says, "Ho, Diz, you gotthe wrong cat for this caper. You're comin' on this gig too far and slow! Maybe a fourth-year gnome could hip this gold bit, but me, I'm a party-boy. Flunked outta my Alma Mammy first year. No matriculation - no magiculation! Readin' me, laddy-buck?"

"Uh, yeah, I guess," I ventured, slowly. "You mean you can't give me a bag of gold like in the fairy tale?"

"Fairy tale, schmerry tale. Maybe one ersatz Korean peso, Max, but that is definitelyit . That is where magic and I parts company. In short,nein, man."

"Hmmm," I hmmmed, tightening my grip a little, he shouldn't get ideas I was letting him get away.

I thought a big think for a minute, then I said, "How come you flunked out of school?"

I thought I detected a note of belligerence in the gnome's voice when he answered, "How would you dig this cla.s.s stuff, man? Go to cla.s.s today, go to cla.s.s tomorrow, yattata-yattata-yat from all these squared-up old codgers what think they are professors? Man, there is so much more else to be doing of note! Real nervous-type stuff like playin' with a jazz combo we got up near campus. You ain't never heard such music!" He appeared to just be starting. "We got a guy on the sackbut what is the coolest.

And on dulcimer there is a little troll what can not only send you - but bring you back. And on topa' all this . . ."

I cut him short, "How about the usual three wishes business? Anything to that?"

"I can take a swing at it, man, but like I says, I'm nowhere when it comes to magicking. I'm not the most, if that's the least. Might be a bit sloppy, but I can take a whirl, Earl."

I thought again for a second and then nodded: "Okay," setting him down on the turf, but not yet letting loose his collar, "but no funny business. Just a straight commercial proposition. Three wishes, with no strings, for your freedom."

"Three?"He was incredulous. "Man,one is about all this power pack can stand at this late date. No, it would seem that one is my limit, guy. Be taking it or leaving it."

"All right, then,one. But no legal loopholes. Let's do it all honest and above-board magic. Deal?"

"Reet!" says he, and races off into The Woods somewhere when I let loose.

I figured he was gone for good, and while I'm waiting, I start to think back on the events of the last few minutes. This is something woulda made Ripley go outta business. The gnome, I figure, is overdue, and so I begin rationalizing why he didn't come back and finally arrive at the conclusion that there is no honor among gnomes. Besides, he had a shifty look to him when he said there would be no tricks in the magic.

But he comes back in a minute, his keychain d.a.m.n near tripping him up, he's so loaded down with stuff and paraphernalia. Real weird lookin' items, too.

"Copped 'em from the lab over at the U.," he explains, waving a hand at the untidy pile of stuff. "Well, here goes. Remember, there may be more of a mess than is usual with an experienced pract.i.tioner, but I'm strictly a goony-bird in this biz, Jack."

"Hey, wait a minute with this magic stuff . . ." I began, but he waved me off impatiently, and began manipulating his implements.

So he starts drawing a star-like thing on the ground, pouring some stinkin' stuff into a cauldron, mixing it up, muttering some gibberish that I could swear had "Oo-bop-shebam" and "Oo-s...o...b..-dooby" inthere somewhere, and a lot of other.

Pretty soon he comes over, sprinkles some powder on me, and I sneeze, almost blowing him over.

"Gesundheit," he mutters, staring at me nastily.

He sprinkles some more powder on me, mutters something that sounded like, "By the sacred ring-finger of The Great G.o.ds Bird and Prez, man, hip this kid to what he craveth. Go, go, go, man!

"Now," he inquires, around a bag in which he is rattling what sounds like bones, "whaddaya want?"

I had been thinking it out, in between incantations, and I had decided what I wanted: "Make me so's I can run faster than anyone in the school, w.i.l.l.ya." I figured then Underfeld wouldhave to take me on the team.

The little gnome nods as if he understands, and starts runnin' around and around outside this star-like thing, in ever-decreasing circles, faster n' faster, till I can hardly make him out.

Then he slows down and stops, puffing away like crazy, mumbles something about, "Gotta lay off them clover stems," and so saying throws this pink powder on me, yelling as loud as he can, "FRACTURED!"

Up goes a puff of pink smoke and what looks like a side-show magician's magnesium flare, and the next thing I know, he and the stuff is gone, and I'm all alone in The Woods.

So that's the yarn.

Hmmm? What's that? Did he make me so I could run faster than anyone else in the school? Oh, yeah, sure.

You know anybody wants to hire a sixteen-year-old centaur?

TRACKING LEVEL.

Well, we're nearing the end of our time together. Has this cheery little package of fantasies made you a better person? Are you kinder to little old ladies and people in wheelchairs?. Do you have respect for the environment and now crave a better cla.s.s of music? Are your armpits kissing sweet, and has your flatulence abated? Listen up: in the history of the written word there are maybe only a hundred or so books that can truly be called "important." That is to say, they changed peoples' minds and habits, brought light and intelligence into otherwise dark and ignorant existences.The a.n.a.lects of Confucius ; Plato'sThe Republic ; theSumma Theologiae of Thomas Aquinas;Don Quixote by Miguel de Cervantes; Pascal, Descartes, Spinoza; Th.o.r.eau, Darwin, Hegel and Kant.Uncle Tom's Cabin and Nineteen Eight-Four . Maybe a hundred and fifty, tops. You won't find thinking as significant as any of that in here. Mostly, these stories were written to entertain, to tell a tale and get a quick reaction. If there are life lessons to be learned, that wisdom can only be unearthed in stories like these by the sharp tool of your imagination. Take this next s.p.a.ce adventure. It's a hunt-and-seek action psychodrama about a guy so consumed with the need for revenge that he forgets the admonition in Shakespeare's line, "heat not a furnace for your foe so hot that thee burn thyself." So what this story says, I suppose, is that when the fire in your gut overpowers the rational coolness in your brain, you are primed to slip on that slippery slope of action/reaction without consideration of consequences. Blind and stupid, we slip and slide through most of our lives. Itseemed like a good idea at the time. But only the thickest brick among you doesn't already know that lesson. If there is magic in this - or any - book, it can only be conjured by wit and intelligence. When you are a creature of raw emotion, behaving on the moment like a dead frog-leg with a live wire in it, you must, I tell you honestly youmust inevitably become somebody's tool, somebody'sfool. Only by keeping alert - remember all Art has but one message: PAY ATTENTION - can you hope to be the one dong the tracking, rather than winding up being the fool tool who has been tracked and finally trapped. That's as close to genuine wisdom as I get, this late in the day.

Claybourne's headlamp picked out the imprint at once. It was faint in the beam, yet discernible, with the telltale mark of the huge, three-toed foot. He was closer than ever.

He drew a deep breath, and the plastic air-sack on his breather mask collapsed inward. He expelled the breath slowly, watching the diamond-shaped sack expand once more.

He wished wildly for a cigarette, but it was impossible. First because the atmosphere of the tiny planetoid would not keep one going, and second because he'd die in the thin air.
