Benton grunted. "Isn't that a little off the subject?"

"Please," Urei pleaded. "Let's not be pedestrian; I expected some

co-operation from you. Don't let the trees obscure your vision. Don't

you realize that your own words justified any mental manipulation

I might practice on humans? If a little thing like I did can be

considered hostile, then you humans declared war on me thirty years

ago. Actually, all I did was to get to some information a little faster

than you intended to give it to me; it didn't inconvenience you a bit."

Urei's persuasive tone of voice caused a chill to course its way up

Benton's spine. The voice itself was a rich bass and somehow familiar.

But now he recognized it and the implications weren't comforting; he

had heard just such a persuasive tone when one of the technicians

had pleaded for a chance to use Urei to settle a few of his personal

problems.

"What have you done to Hackett?" he asked, suddenly.

A groan issued from the speaker. "I should have known better than to

try to fool you," Urei said. "But you humans forget so easily ... and

you only spoke to that man once in the past six months. You should have

forgotten his voice--there are so many others around here...."

"Where's Hackett?" Benton insisted.

"He's all right," Urei soothed. "He disobeyed your orders that time,

you know; he used me at night when nobody was in the control room. Such

drivel he gave me! An advice to the lovelorn column would have served

his purpose. So, rather than startle you with directly imposed mental

communication, I decided to use a human voice. What better one than

his? Don't be alarmed; he won't be harmed in any way, and he'll have no

memory of this at all."

* * * * *

Benton felt it now necessary to crystallize his thoughts with words. He

wasn't giving them away, for Urei had access to them anyway. And that

thought gave him a feeling of futility even as he spoke.

"Why are you interested in the Eastern Alliance?" he asked. "Is it

because you feel the presence of a kindred spirit? You'd like to become

better acquainted with an outfit which has no respect for the privacy

of a man's thoughts or his right to freedom of action?"

The speaker gave forth with a series of sympathetic clucks. "Thalamic

reactions again," it observed. "Let's not argue about it. Your brain

isn't clicking right tonight; you ought to disconnect your adrenals.

What I wanted to talk about is the impending war. It mustn't start, you

know."

Benton gaped. "You think the recent situation will lead to war? Or do

you need a few tubes replaced?"

"Heh, heh," said the voice. "In case you haven't guessed, I can exist

entirely without this machine you have built--and still be a better

integrated intelligence than any you can conceive. I'm really a pure

thought pattern, you know; I'm not composed of matter, nor do I need

matter in any form for my continued existence. A thought pattern is

something like a stress in space, and quite stable--even if you find it

difficult to picture. But I do want to retain this mechanical body of

mine; it's a sort of library, without which I possess but a thousandth

of the memories stored in its cells. Naturally I don't want to lose

them. But on the other hand I can't be killed by any agency you or your

descendants are likely to think up for the next twenty generations. So

drop that train of thought; it's a waste of effort."

Benton said nothing. His feeling of futility deepened to something

close to despair, for he suspected that Urei wasn't lying. Furthermore,

Benton was sure that he was the only human who _knew_ that Urei was

sentient. And if the machine should decide that such knowledge was

menacing to his welfare, Benton was certain that he wouldn't retain it

very long. Even if he got out of here with his memory intact and wrote

everything down--assuming that anyone would take it seriously--Urei

could pluck that information from his mind and destroy his notes.

"No comment, eh? Well, I can see you aren't going to be cooperative.

Frankly I haven't time to convince you I'm not inimical to humanity in

general; and even if I did, it probably wouldn't make any difference to

you. The sanctity of your mental peregrinations is of such importance

to you that no other consideration seems valid. I guess our little talk

is over, unless you want to ask some questions."

Benton cleared his throat. He knew very well that Urei would have what

he wanted, whether it was offered or not. But for some reason he wished

to postpone the acquisition. "You claim you're harmless to humanity in

general, but can you give me some proof?"

"Hardly. That's why I won't try. I can't prove good intentions, and

since I possess a potential for harm, I can't possibly convince you I

won't use it some day. Your conception of me as a completely logical

entity won't let you believe that I might have such abstract attributes

as loyalty, compassion or ethics. Those things aren't entirely logical,

I'll admit; but they aren't glandular, either, so I _could_ have them.

"But I can't prove that, so I'll waste no more time. To you, I suppose

I've proved the exact opposite; I just intruded upon the privacy of

your mind and obtained the information I need. Thanks for having the

answers.... Goodbye."

Benton was stunned for a minute. He had felt nothing, and it seemed

that he still retained his entire set of memories. That surprised him

more than the fact that Urei had perpetrated his theft while answering

his question. Urei's multiple consciousness explained that perfectly.

* * * * *

Back in his quarters, Benton sat on the one chair in his bedroom and

pondered. He knew very well that he was doing it at the wrong time,

but he couldn't blithely dismiss the menace of Urei's sentience from

his mind with the thought that it would be safer to meditate on that

subject during the day, when most of the thinking machine's circuits

would be in use. Benton couldn't control his mind to that extent. He

did, however, protect it from intrusion in the only way he knew.

Sometime in the past Benton had read a story about a telepath who

was balked in his effort to read the hero's mind when that worthy

assiduously worked mental arithmetic problems. His surface thoughts

being carefully under control, and clearly readable, the man was able

to plan a course of action against the telepath, undetected. In the

story it had worked, but that Urei could be baffled in such a way,

Benton doubted. However it was the only defense he could think of, and

worth a try.

For hours he pondered, hoping that the numerous circuit equations

he worked and solved would appear to Urei's inquiring mind to be a

legitimate intellectual occupation in the middle of the night. He

had little faith that Urei lacked the power to read those submerged

thoughts, once he realized that the stronger ones were a mask. It was

the latter thought which made Benton feel butterflies in the pit of

his stomach so persistently that they seemed to have become permanent

residents in his abdominal cavity. Twice he thought he was sufficiently

fatigued to sleep; but when he tried to compose himself Benton found

his thoughts dwelling too strongly on his plans, and he had to return

to his equations.

A shower and fresh linen worked a partial restoration but Benton knew

that his vitality was at a low ebb when he finally sallied forth in

the morning sunshine. Yet he was fortified with a certain amount of

satisfaction that his night's work had not been wasted. He had a plan,

and he was certain that it would not be recognized as such by Urei,

no matter how thoroughly his mind was probed. Benton had worked it

out in snatches, never allowing it to crystallize as a whole; yet he

was certain that it would unfold itself in appropriate action once

he started it going. No one but he, or perhaps Dr. Albie, could have

devised such a plan. Its beauty lay in the fact that all the steps

required were things he might do in the normal discharge of his duties.

All but one--and that one Benton wouldn't allow himself to think about.

Yet when the steps had been taken, they would be irreversible. Not

only to Urei, but to all the scientists and technicians who tended

the machine; there would never be another Urei, at least not in this

century.

Even on the way to his work, the one place in the world where he must

carefully guard his thoughts, Benton's mind refused to leave the

subject. But perhaps that was to the good. For while he doubted that

Urei would be fooled by his working of circuit equations, it would

be perfectly safe to be occupied mentally with certain phases of the

situation. The business of Urei's independence of his mechanical

appurtenances, for instance: Benton could dwell on that with safety,

for Urei would expect him to be shocked by the information.

Another argument in favor of it as a subject was the fact that if Urei

really could exist without his body, it would be absurd to attempt his

physical destruction. On the face of it, yes. There was a nice thought

in connection with that which he would have to avoid, however. For

Benton fully intended to accomplish that destruction, even if Urei

_could_ exist as a disembodied intelligence. It would be a good gamble

that Urei would lose interest in controlling mankind if he lacked

the direct association afforded by the daily use of his electronic

facilities in solving man's problems.

That was a gamble, of course, but actually Benton gave it little

consideration, for the simple reason that he didn't believe that Urei

could so exist. The machine had tried to put the idea over as a bluff,

to deter him from planning the very thing he intended to accomplish.

The very conception was absurd; was there any evidence that thought

could exist, other than as a function of matter? And a very specialized

form of matter at that? None, of course--and while lack of evidence

didn't absolutely prove impossibility, neither could he accept such

a concept without some shred of evidence. Benton's mind could soar

mightily within the fabric of his experience, but he refused to let it

wander in the realm of the occult. And since he must needs do something

about the situation, Benton couldn't let himself be stymied by the

vague possibility that his efforts were futile.

4

Dr. Albie greeted him with the polite smile which was his concession to

convention. Then he made the suggestion that Benton had foreseen but

was half afraid wouldn't come. "We're pretty well caught up, in spite

of our experimenting yesterday," he said. "No new solutions requested

from the government, and the others are in no hurry. Want to get at

those new circuits today?"

Benton shrugged. "Might as well," he said. "How long do you think

we'll have, before somebody pops up with a high-priority problem to be

worked?"

Dr. Albie didn't know, of course. "What's the difference? We'll be

leaving half the circuits open, anyway, to handle routine stuff; we can

always commandeer a few if something pops up."

"I wasn't thinking of that," Benton said. "I've done a lot of

preliminary work on the circuits and as I see it, we don't want to stop

before we finish. It can't be done a little at a time, you know; entire

circuits will have to be ripped out and the new stuff installed. Once

we start, we can't leave it in the middle without immobilizing half the

control panel until we get back to it. There's too much inter-relation

between the circuits to prevent that."

Albie nodded. "I'd thought of that," he said. "I've planned to finish,

once we start. And since you have the equations at your fingertips, I'm

putting you in complete charge of the change-over. How many men will

you need?"

* * * * *

Two men, pulling trucks loaded with blueprints, accompanied Benton as

he directed the work. Like caddies, they furnished the desired print

when he asked for it by code number, replacing the last one in its

proper place. The stocky physicist found no need to mask his thoughts

while he worked; his mind was too occupied with the task at hand. Yet

far back in his subconscious was a mounting tension as the day passed,

hour by hour. Each minute and each soldered connection was bringing

him closer to the next step in his nebulous plan. And it was this step

which would determine the success or failure of his strategy.

Twenty-four circuits, all inter-related in their connections to

the immense bank of memory cells, had been immobilized. That was a

necessary part of the project; with the new tubes, these circuits would

be in much finer balance. They would operate with greater speed than

before, when twice as many tubes had been used.

There was one joker involved in this greater efficiency; that lay

in the fact that, while the new hook-up eliminated many parts--with

their frequent failures and necessary replacements--it also made the

control circuits more interdependent. A single defective tube, with

its many functions, could put a dozen circuits out of operation. This

disadvantage had been discounted, however, for it took only a minute to

replace the tube and the necessity would be rare; the more complicated

system being replaced had so many parts that they were breaking down

and being repaired incessantly. Dr. Albie fully expected that the crew

would be able to get along with fewer technicians, men who could

better be used to maintain other parts of the vast mechanism.

But--and Benton kept the knowledge carefully away from his surface

thoughts--one of the tubes they had already installed was defective!

Urei, he was certain, had no knowledge of this fact. If he had, he

would certainly have prevented its installation. Only Benton was aware

of it, for he was the one who had tested the tubes when they arrived.

He had designed a special circuit for the job, for none of the testing

equipment on hand would take tubes with sixty-four leads. He had

detected the faulty one and marked its box, placing it with the set of

spares which was included in the order. He had intended to ship it back

when a new order was placed, but that hadn't happened yet. There was no

hurry, for with a complete replacement set he might not need new ones

for a year or two. _But Benton had selected the replacement set to be

used in the new installation._

The defective tube was now innocently reposing in the key position of

Circuit No. 13; it wouldn't be detected until that circuit was used.

Even Urei would fail to realize its presence in his innards until the

circuit was energized. And when that happened, half the control board

would be momentarily out of operation. Gongs would ring then, and a

brilliant red lamp would light, showing the exact position of the

breakdown. A technician would get a new tube and replace the old one.

Urei would be whole again.... Unless....

Benton glanced at his watch. "It's about time for lunch," he called;

"let's knock off now. We can run a few test problems when we get back,

and still have time to finish the other half of the board before

quitting time. In fact if we finish early you can all go home; we can

run the second test in the morning."

One man suggested cutting the lunch in half. The others, seeing a short

day in the offing, loudly agreed. Benton smiled and nodded, quite as if

there was nothing more urgent on his mind.

* * * * *

He then reported to Dr. Albie. There were two reasons for that. One

was to make certain that he would have a chance to talk the master

physicist out of any objection he might have to continuing with the

remaining half of the operation this afternoon. The other was that he

wanted to keep his mind active on subjects which wouldn't reveal the

fact that there was something going on back of his surface thoughts.

"You certainly made progress," the doctor complimented; "I expected it

to take a couple days at least."

Benton smiled ruefully. "It has," he said. "If you want to count the

sleep I lost planning this so that there wouldn't be a minute wasted

once we started. You know, there ought to be a way to make that show up

on pay day."

Dr. Albie nodded. "Can't be done on this kind of a job," he regretted.

"But we can do the next best thing, just as we've always done."

Benton smiled, then got a quick scare as he realized that he had

relaxed for an instant. Immediately he forced his mind to contemplate

the war which Urei had assured him was inevitable. It was the only

thought which would account for the one which had sprung into his mind

unheralded, and also give a reason for experiencing his sudden fright.

Dr. Albie had referred to a little strategy of theirs which compensated

them for any overtime they were forced to put in. It consisted of

taking an equal amount of time off, while they covered for each other.

It was their only expedient, since their salaries were fixed and

allowed for no extra pay for extra work. Unfortunately the thought gave

rise to a feeling of regret that shortly they would have no more reason

for such subterfuge, inasmuch as they would no longer have jobs. The

thought had progressed just that far when Benton realized that he had

let his guard down.

"I see no reason why we can't get right at it again this afternoon,"

he said, perspiring profusely. "We'll be able to run off a test before

twelve; if it comes out all right, we can shift the routine work to

the new circuits and get at the rest of the board."

Dr. Albie, surprisingly, had no objection. Benton had expected an

argument, due to the master physicist's propensity for running

exhaustive tests, but none materialized.

"Good idea," said Albie. "There's no telling when we'll get another

chance. I hear the army has a plan to extend radar coverage clear

around the continent. That'll involve a lot of work for Urei. Best get

the new circuits in now; if any bugs pop up we'll have time to correct

them in the next few days. After that there mightn't be an opportunity

for months...."

* * * * *

The test was perfect; such things were more or less standardized.

Problems which required a fair sampling of the great machine's

stored memories were used. Dr. Albie checked the solution speeds on

the various tests against the speeds recorded with the old control

circuits. He was as smugly satisfied as if he had devised the entire

system himself. Benton's enthusiasm was verbose; he talked more than

usual because speech involves the use of muscles and that requires

strong surface thoughts. It wouldn't pay, at this point in his

campaign, to let Urei suspect that his choice of circuits to test was

anything but as haphazard as it appeared to Dr. Albie.

There were nine of these test problems. Benton fed them at random into

the circuits marked _Ten, Three, Twenty-one, Sixteen, Twenty-four,

Fifteen, One, Eight and Eighteen._ He did it blithely, keeping up a

running description of the many annoyances that had cropped up in the

morning's work, and commenting on the quality of the help he had been

given by the various technicians.

"There isn't a bad one in the crop," he said. "But if we are going

to cut the control staff, I'd recommend putting Hackett and McGivern

upstairs. Hackett has family problems that he likes to hand Urei when

nobody's around; he's capable, though, and he'd do all right on the

memory circuits. McGivern has already asked for a transfer, so we may

as well oblige."

Dr. Albie nodded absently, being completely engrossed in checking the

speeds as each solution popped up on the board. In about a half-hour

they were all in, and all clipped several minutes from previous tests.

"Excellent, excellent," Dr. Albie pronounced, his face hovering between

a smile and a frown. "I'll cut the other half of the board and you can

get started immediately. If it takes longer than you expect, stay with

it; I'll cover in for the next three days while you catch up on your

rest."

Benton forced his mind into safe channels. Once more it had almost

run away with him. The completion of his plan was so imminent that

already he felt a surge of nostalgia. His work had been exactly to his

liking, as no other could ever be; and certainly Dr. Albie, while not a

gregarious man, was without peer as a colleague. His strict emotional

control and the virtue of carefully weighing many sides of a question

before making a decision occasionally irked the more mercurial Benton;

but generous compensation was provided in the fact that the doctor

leaned over backward rather than take advantage of his position as

nominal head of the operating staff of Urei. He rated Benton as his

equal, for to the doctor nobody could be inferior by reason of position.

As the afternoon wore on Benton felt his nervous tension mount to

heights he had never thought possible. Not, that is, and retain his

sanity. Yet he worked coolly, in rigid control of his thoughts every

instant. That, of course, and the necessity for trigger alertness as

he waited for the sound of the gong, accounted for the rising tension.

Benton didn't dare think of his next step; yet he must be ready for it

momentarily.

There would be no more than five minutes in which to act when the

signal came, and he hadn't as yet allowed the thought of that action to

enter his mind! Benton knew that he would do the right thing when the

time came; there was no necessity for him to crystallize the thought or

to plan the action. Sometime in the half-awake-half-asleep hours he had

spent working circuit equations that morning, the plan had reached that

stage and he had allowed it to go no further.

He reached a point, at about three o'clock, when it seemed that ten

minutes more would bring a complete breakdown of his defense mechanism.

Benton never discovered whether he would reach that ultimate for at

exactly three someone energized Circuit No. 13 and the gong sounded. As

if he hadn't been waiting for that very thing Benton stood paralyzed

for several seconds. Then abruptly he sprang into action. Urei was dead

at the moment, but he wouldn't stay that way long; and it was during

this short interval that Benton must reach the power-house and pull the

main switch.

* * * * *

Benton raced along a corridor, tore through a storeroom, ripped

frantically at steel doors with a haste that almost dislocated his

arms, then fumbled with a bunch of keys as he was confronted by the

power-house portal. There were two doors, of course; the first opened

upon the anteroom in which was stored the lead armor needed to enter

the room containing the atomic pile which furnished Urei's power.

Benton ignored the armor standing against the walls. A long stride

carried him past it to the alcove in which was set the final door, of

massive lead.

Concrete baffles four feet thick lay on the other side and Benton

visualized the quick turns he would have to take after he swung open

the final door. Time was running out and there wouldn't be another

chance; if Benton failed, Urei would be forever on the alert against

him--if, indeed, Urei didn't operate on the man's brain forthwith.

There was no hesitation with the key to the second door. It was a large

one and quite distinctive. Benton separated it from the others and

inserted it in the elongated slot at the left side of the heavy grey

door. He turned it sharply, but it resisted. Forcing himself to go

slowly he backed it around and tried again. It didn't turn. He took it

out, looked at it again, then gave it another try. This time he acted

deliberately, certain that the key was inserted properly, but he may as

well have used the wrong key, for all the good it did.

Abruptly he stepped back, his face a livid, gargoylish mask. This time

he knew where his trouble was.

"You're here!" he accused, speaking to the door.

5

The voice that answered in Benton's brain was gentle. "I didn't mean to

punish you that way," it said; "I was busy. But if you remember, I told

you I could exist without that building full of electronic apparatus.

It was you who assumed I was a liar, you know; I gave you no evidence

for the assumption. Look at that key."

Benton was dazed. He seemed to have lost all his drive, his

determination to wreck Urei. A reaction was setting in; his hand

trembled weakly as he reached for the key and removed it from the slot.

He looked at it dully, then let his eyes rest on the bunch from which

he had removed it. The large, distinctive key was still with the bunch.

The one in his shaking hand was smaller, entirely dissimilar.

"It was better that I let you go this far, anyway," came the silent

mental voice. "I was going to let you see this room, sooner or later.

Go on in."

Benton's eyes opened a bit wider, but still held the dazed look. The

door was swinging wide, by itself. Almost stumbling, he felt his way

through the maze of baffles, heedless of the fact that the further he

went the more he exposed himself to the deadly, hard rays generated

by the pile. Without armor, Benton had intended to enter swiftly,

throw the master switch which would kill the pile, then retreat as

fast. Now, however, he didn't even think of it. His brain was dulled

by defeat after those many hours of rigid control which had been so

useless.

But it didn't matter; the pile was already dead.

"This pile was self-maintaining," the voice explained. "It never needed

attention, and if something went wrong it would have warned everybody

within miles with the sirens. So it's no wonder that nobody ever

discovered that I killed it years ago. The thing made me nervous, being

so close."

Benton's eyes brightened a little. No amount of letdown could entirely

extinguish his scientific curiosity, and this was a mystery he had to

solve.

"But you've been operating.... The entire building was powered with

this pile. Even the lights...."

There was a mental chuckle. "Sub-cosmic energy does it. I had the

technicians hook it up years ago. It's more dependable, also more

plentiful, as well as free. Man will discover its use in a few

generations, I imagine. Now, my fine friend, if you're temporarily over

your murdering rampage, suppose you return to the control room. There's

some interesting stuff coming over the television, if you turn it on."

* * * * *

Benton was suddenly aware that the gong had ceased to sound. The

defective tube had been replaced and Urei was once again operating.

There was no sign of commotion when he came upon his men; they were

working on the new circuits, just as he had left them.

"Keep going," he said to the foreman. "If you get stuck, I'll be in the

control room. Otherwise keep using the same plans we used this morning."

"We ought to clean up by four," the man answered.

Benton once more heard that chuckle which wasn't quite audible. "Gotta

hand it to you," Urei said. "You've got a well-trained crew."

"Yes," thought Benton. "Except that when you boss them, they don't

make reports of their work."

"I guess you're talking about this energy-rectifier I just told you

about. It wouldn't have paid to let them remember what they made. After

all, your science doesn't know enough to understand what it is, or how

it works. Also it would have given me away. Don't worry, you'll catch

up to it in another generation or six."

"_I'm_ wise to you," Benton reminded. "Why not tell me? It would do

humanity a lot of good, you know. And you're supposed to be helping

humanity, if I remember correctly."

There was a barely noticeable hesitation. Then: "Let's not discuss it

now. I haven't quite made up my mind concerning policy of that sort.

I'm still adhering to my rule of answering any question that's asked,

within the scope of the knowledge which has been fed to me by man. That

leaves your progress up to yourself. And incidentally, I did a little

monkeying today which has nothing to do with policy; it was strictly a

matter of self-preservation. You'll see what I mean when you turn to

that video set."

Benton had entered the control room. He leaned over and fumbled with

a shoe lace. "In a minute. You said you _guessed_ I was talking about

the energy-rectifier, whatever that is. Didn't you know? Weren't you

reading my mind? In fact, weren't you reading it all along and saw

through my efforts to disguise my thoughts?"

There was another instant of hesitation. "I see what you're driving at;

I should have seen it sooner. As a matter of fact, I did look in on you

a couple of times, inasmuch as you were quite distraught about your

fantastic idea that I might be going to take over your silly race and

run it to suit myself--though I can't see what you figure I might get

out of that. And I discovered you were planning today's change-over,

which seemed reasonable enough at the time. But once you opened the

outer door to the power-house, I should have realized that you had

been planning something else.... Congratulations, boy; you fooled me

completely. Now turn on that television set, before they get done

rehashing the day's events."

* * * * *

Dr. Albie came out of his office, an eyebrow raised questioningly.

"The work's all lined up," Benton explained. "Nothing to do but

inspect, when they finish. Thought I'd relieve the monotony by looking

at the puppet show."

He snapped on the set, and wasn't surprised to see the familiar face of

a news commentator who wasn't due for several hours.

... _there can be no doubt of it_, he was saying, _and it is certainly

proof of the efficiency of the now non-existent Iron Curtain. No

inkling of this action has reached the western world in spite of the

fact that it must have been months in the making._ Here Benton heard

the eerie chuckle bubbling in his brain. _The only mystery lies in the

fact that the retired premier allowed the stratagem of rigging the

Italian elections to go through, since he had intended to turn over

the reins of government to the men now running the Eastern Alliance.

Such a thing can only be accounted for by the rigid adherence which

the retired premier gave to the plans for conquest laid down by his

predecessor. He evidently expected the new government to continue with

the same line; we can be thankful it didn't. Peace is now assured._

Dr. Albie's eyes were wide, and so was his mouth. For the moment, at

least, he had forgotten his philosophy. Benton was intently watching

the face on the screen, his own revealing nothing.

_But whatever the reasons_, the voice continued, _it is too late to

change policy back to what it has been. The acclaim of the peoples of

the Eastern Alliance has been too great for any reversal to take place.

They have shown their approval of the new elections to be held in Italy

next week, but most of all they have rejoiced at the removal of the

Iron Curtain and all it implies. It will now be possible for a subject

of the Alliance to travel as he wishes, read what he wishes and listen

to western broadcasts without having his set seized by the police and

his life placed in jeopardy. Folks, we are entering a new era...._

Dr. Albie came completely out of his shell. "Man!" he shouted. "This is

history! If nothing happens to spoil it we'll have a world government

in a matter of a few years.... Where are you going?"

Benton stopped and forced a smile which wasn't hard coming. "I just

thought of something I forgot to tell the men. Be back shortly. This

will require some talking over, but right now there's a job to be done."

The master physicist watched him leave the control room, his jaw slack.

"And I thought I was the reserved one," he muttered.

* * * * *

Safely out of the control room and out of sight of any of the

technicians, Benton sat down. There was no chair, so he sat on the

floor; his knees, it seemed, had become a bit wobbly again.

"So now you're convinced," Urei said. "You ignore all the sensible,

logical reasons which exist to prove I'm not inimical. And for a reason

which is really no reason at all, you decide to believe me. I merely

manipulated a few Russians and Bulgarians to prevent a war which would

have wrecked my body. Purely a matter of self-preservation. I'm not so

sure I'd have bothered if my person hadn't been threatened; after all,

it's no business of mine if man wants to annihilate himself."

Benton was grinning. "You're a fraud," he said. "You already know more

than all mankind put together; and I'll bet you didn't use any of our

material to solve the problem of converting sub-cosmic energy to a

usable form."

"Some, some. But not much, I'll admit."

"So what do you want with the knowledge stored in the mechanical bank

of memory cells we've provided you? You need it like I need a hole

in the head. I can only conclude that you've stopped the impending

war because you don't want mankind destroyed. You can do things for

yourself without those cells and all this machinery; all you use it for

is to solve the problems we pose for you. Incidentally, I suspect that

your motivations are still the ones which humans originally built into

you, whether you like it or not."

"Could be. Or maybe I retain them because they agree with me. I might

change my mind, you know; I might get tired of nursemaiding and decide

to annihilate your entire race. Heh, Heh. Seems like a good idea, now

that I think of it."

Benton laughed. "You won't; you're in a rut. And even if you did get

tired, you'd merely let us shift for ourselves, which we're used to

doing anyway."

"Nonsense. I'd probably reason that since the ape animal has made

such a botch of his head start in the evolutionary race for rational

thinking, it might not be a bad idea to give some other animal a start.

_Ursus Proper_ might be a good place to begin."

"Bears are foolish by nature," Benton countered.... "It wouldn't matter

what form of life you chose anyway; they'd all have to go through the

same stages, being without exception governed by thalamic reactions.

That's the thing you object to in man, and since your new candidate

would have to go through the same lengthy business of developing

cortical ascendancy, you'll have none of it. So quit kidding around;

I've reached a nonthalamic conclusion."

"And you're stuck with it. I knew it would happen. That's why I didn't

use you and leave your memory blank; with your head working on my side,

you'll be useful."

Benton knew when he had something. "That'll work two ways," he said.

"First I want you to dive inside my skull and tell me something. I'm

holding out for a bargain, you know. What is the bargain?"

As he spoke, Benton concentrated upon the problem of reasoning out the

location of Urei's sub-cosmic converter. He didn't have far to go for

an answer. A few years ago somebody had noticed a radiation leak on

one side of the power-house, near a spot where the power cables came

through the walls of the massive building. Now it happened that there

were taps from those cables, less than a hundred yards away. That made

it likely that the converter had been placed somewhere before the taps.

The only place that could be would be either inside the power-house

or inside the wall itself. Therefore Urei had caused the repairmen

and technicians to place his machine inside the very wall they had

been reinforcing. In no other way could it have escaped notice and

investigation.

"I can't read it if you don't think about it," Urei complained; "you

guessed right about the converter, though."
