<p>The situation was crystal-clear. Big Jake Connors was displeased with
Brink. In all the city whose rackets he was developing and
consolidating, Brink was the only man who resisted Big Jake's civic
enterprise—and got away with it! And nobody who runs rackets can permit
resistance. It is contagious. So Big Jake had ordered that Brink be
brought into line or else. The or else alternative had run into snags,
before, but it was being given a big new try.</p>
<p>There was the shrill high clamor of two women screaming at the tops of
their voices because revolvers were waved at them. One Elite employee,
at the pressing machine, took his foot off the treadle and steam
billowed wildly. Another man, at a giant sheet-iron box which rumbled,
stared with his mouth open and blood draining from his cheeks. Brink,
alone, looked—quite impossibly—amused and satisfied.</p>
<p>"Get outside!" snarled a voice as Fitzgerald's revolver came out ready
for action. "This joint is finished!"</p>
<p>The companion of the snarling man rubbed suddenly at his eye. He rubbed
again, as if it twitched violently. But it was, after all, only a
twitching eyelid. He reached negligently down and picked up a wooden
box. By its markings, it was a dozen-bottle box of spot-remover—the
stuff used to get out spots the standard cleaning fluid in the
dry-cleaning machine did not remove.</p>
<p>The man heaved the box, with the hand with which he had rubbed his
twitching eye. The other man raised a hand—the one not holding a
revolver—to rub at his own eye, which also seemed to twitch agitatedly.</p>
<p>Detective Sergeant Fitzgerald had his revolver out. He drew in his
breath for a stentorian command for them to drop their weapons. But he
didn't have time to shout. The hurtling small box of spot-remover struck
the large sheet-iron case from which loud rumblings came. It was a
dryer; a device for spinning clothes which were wet with liquid from the
dry-cleaning washer. A perforated drum revolved at high speed within it.
The box of spot-remover hit the door. The door dented in, hit the
high-speed drum inside, and flew frantically out again, free from its
hinges and turning end-for-end as it flew. It slammed into the thrower's
companion, spraining three fingers as it knocked his revolver to the
floor. The weapon slid merrily away to the outer office between
Detective Fitzgerald's feet.</p>
<p>But this was not all. The dryer-door, having disposed of one threatening
revolver, slammed violently against the wall. The wall was merely a thin
partition, neatly paneled on the office side, but with shelves
containing cleaning-and-dyeing supplies on the other. The impact shook
the partition. Dust fell from the shelves and supplies. The hood who
hadn't lost his gun sneezed so violently that his hat came off. He bent
nearly double, and in the act he jarred the partition again.</p>
<p>Things fell from it. Many things. A two-gallon jar of extra-special
detergent, used only for laces, conked him and smashed on the floor
before him. It added to the stream of fluid already flowing with
singular directness for the open, double, back-door of the workroom. The
hood staggered, sneezed again, and convulsively pulled the trigger of
his gun. The bullet hit something which was solid heavy metal,
ricocheted, ricocheted again and the second hood howled and leaped
wildly into the air. He came down in the flowing flood of spilled
detergent, flat on his stomach, and with marked forward momentum. He
slid. The floor of the plant had recently been oiled to keep down dust.
The coefficient of friction of a really good detergent on top of
floor-oil is remarkably low,—somewhere around point oh-oh-nine. Hood
number two slid magnificently on his belly on the superb lubrication
afforded by detergent on top of floor-oil.</p>
<p>The first hood staggered. Something else fell from the shelf. It was a
carton of electric-light bulbs. Despite the protecting carton, they went
off with crackings like gunfire. Technically, they did not explode but
implode, but the hood with the revolver did not notice the difference.
He leaped—and also landed in the middle of the wide streak of
detergent-over-oil which might have been arranged to receive him.</p>
<p>He remained erect, but he slid slowly along that shining path. His
relatively low speed was not his fault, because he went through all the
motions of frenzied flight. His legs twinkled as he ran. But his feet
slid backward. He moved with a sort of dignified celerity, running fast
enough for ten times the speed, upon a surface which had a frictional
coefficient far below that of the smoothest possible ice.</p>
<p>Detective Sergeant Fitzgerald gaped, his mouth dropped open and his gun
held laxly in a practically nerveless hand.</p>
<p>The thing developed splendidly. The prone gunman slid out of the wide
double door, pushing a bow-wave of detergent before him. He slid across
the cement just outside, into the open garage whose delivery-truck was
absent, and slammed with a sort of deliberate violence into a stack of
four cardboard drums of that bone-black which is used to filter
cleaning-fluid so it can be used over again in the dry-cleaning machine.
The garage was used for storage as well as shelter for the
establishment's truck.</p>
<p>The four drums were not accurately piled. They were three and a half
feet high and two feet in diameter. They toppled sedately, falling with
a fine precision upon the now hatless, running, sliding hood. One of
them burst upon him. A second burst upon the prone man—who had butted
through the cardboard of the bottom one on his arrival. There was a
dense black cloud which filled all the interior of the garage. It was
bone-black, which cannot be told from lamp-black or soot by the
uninitiated.</p>
<p>From the cloud came a despairing revolver shot. It was pure reflex
action by a man who had been whammed over the head by a
hundred-and-fifty-pound drum of yielding—in fact bursting—material.
There was a metallic clang. Then silence.</p>
<p>In a very little while the dust-cloud cleared. One figure struggled
insanely. Upon him descended—from an oil drum of cylinder-oil stored
above the rafters—a tranquil, glistening rod of opalescent
cylinder-oil. His last bullet had punctured the drum. Oil turned the
bone-black upon him into a thick, sticky goo which instantly gathered
more bone-black to become thicker, stickier, and gooier. He fought it,
while his unconscious companion lay with his head in a crumpled
cardboard container of more black stuff.</p>
<p>The despairing, struggling hood managed to get off one more shot, as if
defying even fate and chance. This bullet likewise found a target. It
burst a container of powdered dye-stuff, also stored overhead. The
container practically exploded and its contents descended in a
widespread shower which coated all the interior of the garage with a
lovely layer of bright heliotrope.</p>
<p>Maybe the struggling hood saw it. If so, it broke him utterly. What had
happened was starkly impossible. The only sane explanation was that he
had died and was in hell. He accepted that explanation and broke into
sobs.</p>
<hr style='width: 45%;' />
<p>Detective Sergeant Fitzgerald had witnessed every instant of the
happening, but he did not believe it. Nevertheless, he said in a strange
voice: "I'll phone for the paddy-wagon. It'll do for a ambulance, in
case of need."</p>
<p>He put away his unused service revolver. Thinking strange, dizzy
thoughts of twitching eyelids and plastic scraps and starkly incredible
happenings, he managed to call for the police patrol. When he hung up,
he gazed blankly at the wall. He gazed, in fact, at a spot where a
peculiar small machine with no visible function reposed—somewhat
dusty—on a shelf.</p>
<p>Brink stepped over briskly and closed the door between the scene of
catastrophe and the immaculate shop. Somehow, none of the mess had
spilled back through the doorway. Then he came in, frowning a little.</p>
<p>"The fight's out of them," he said cheerfully. "One's got a bad cut on
his head. The other's completely unnerved. <i>Tsk! Tsk!</i> I hate to have
such things happen!"</p>
<p>Sergeant Fitzgerald shook himself, as if trying to come back to a normal
and a reasonable world.</p>
<p>"Look!" he said in a hoarse voice. "I saw it, an' I still don't believe
it! Things like this don't happen! I thought you might be lucky. It
ain't that. I thought I might be crazy. It ain't that! What has been
goin' on?"</p>
<p>Brink sat down. His air was one of wry contemplation.</p>
<p>"I told you I had a special kind of luck you couldn't believe. Did your
eyelids twitch any time today?"</p>
<p>Fitzgerald swallowed.</p>
<p>"They did. And I stopped short an' something that should've knocked my
cranium down my windpipe missed me by inches. An' again—But no matter.
Yes."</p>
<p>"Maybe you can believe it, then," said Brink. "Did you ever hear of a
man named Hieronymus?"</p>
<p>"No," said Fitzgerald in a numbed voice. "Who's he?"</p>
<p>"He got a patent once," said Brink, matter-of-factly, "on a machine he
believed detected something he called eloptic radiation. He thought it
was a kind of radiation nobody had noticed before. He was wrong. It
worked by something called psi."</p>
<p>Sergeant Fitzgerald shook his head. It still needed clearing.</p>
<p>"Psi still isn't fully understood," explained Brink, "but it will do a
lot of things. For instance, it can change probability as magnetism can
change temperature. You can establish a psi field in a suitable
material, just as you can establish a magnetic field in steel or alnico.
Now, if you spin a copper disk in a magnetic field, you get eddy
currents. Keep it up, and the disk gets hot. If you're obstinate about
it, you can melt the copper. It isn't the magnet, as such, that does the
melting. It's the energy of the spinning disk that is changed into heat.
The magnetic field simply sets up the conditions for the change of
motion into heat. In the same way ... am I boring you?"</p>
<p>"Confusing me," said Fitzgerald, "maybe. But keep on. Maybe I'll catch a
glimmer presently."</p>
<p>"In the same way," said Brink, "you can try to perform violent actions
in a strong psi field—a field made especially to act on violence. When
you first try it you get something like eddy currents. Warnings. It can
be arranged that such psi eddy currents make your eyelids twitch. Keep
it up, and probability changes to shift the most-likely consequences of
the violence. This is like a spinning copper disk getting hot. Then, if
you're obstinate about it, you get the equivalent of the copper disk
melting. Probability gets so drastically changed that the violent thing
you're trying to do becomes something that can't happen. Hm-m-m. ... You
can't spin a copper disk in a magnetic field when it melts. You can't
commit a murder in a certain kind of psi field when probability goes
hog-wild. Any other thing can happen to anybody else—to you, for
example—but no violence can happen to the thing or person you're trying
to do something violent to. The psi field has melted down ordinary
probabilities. The violence you intend has become the most improbable of
all conceivable things. You see?"</p>
<p>"I'm beginnin'," said Detective Sergeant Fitzgerald dizzily, "I'm
beginnin' to get a toehold on what you mean. I'd hate to have to testify
about it in court, but I'm receptive."</p>
<p>"So my special kind of luck," said Brink, "comes from antiviolence psi
fields, set up in psi units of suitable material. They don't use up
energy any more than a magnet does. But they transfer it, like a magnet
does. My brother-in-law thought he had to lose his business because Big
Jake threatened violent things. I offered to take it over and protect
it—with psi units. So far, I have. When four hoods intended to shoot up
the place and moved to do it, they were warned. Psi 'eddy currents' made
their eyelids twitch. They went ahead. Probability changed. Quite
unlikely things became more likely than not. They were obstinate about
it, and what they intended became perhaps the only thing in the world
that simply couldn't happen. So they crashed into a telephone pole. That
wasn't violence. That was accident."</p>
<p>The detective blinked, and then nodded, somehow painfully.</p>
<p>"I see," he said uncertainly.</p>
<hr style='width: 45%;' />
<p>"Somebody set a bomb in my delivery truck," added Brink. "I'm sure his
eyelids twitched, but he didn't stop. So probability changed. The
explosion of that bomb in my truck became the most unlikely of all
possible things. In fact, it became impossible. So some electric
connection went bad, and it didn't go off. Again, when Jacaro intended
to plant a time fire-bomb to set the plant on fire—why—his eyelids
must have twitched but he didn't give up the intention. So the psi unit
naturally made the burning of the plant impossible. For it to be
impossible, the fire-bomb had to go off where it would do next to no
harm. Jacaro lost his pants."</p>
<p>He stopped. Detective Sergeant Fitzgerald swallowed carefully.</p>
<p>"I don't question it," he said dizzily, "even if I don't believe it.
Will you now tell me that what just happened was a psi something keepin'
violent things from happening?"</p>
<p>"That's it," agreed Brink. "The psi unit made the dryer-door fly off and
knock a pistol out of a man's hand. If they'd dropped the idea of
violence, that would have ended the matter. They didn't."</p>
<p>"I accept it," said Fitzgerald. He gulped. "Because I saw it. A court
wouldn't believe it, though, Mr. Brink!"</p>
<p>"Well?"</p>
<p>"I've been tryin' for months," said Fitzgerald in sudden desperation,
"to find a way to stop what Big Jake's doin'. But he's tricky. He's
organized. He's got smart lawyers. Mr. Brink, if the cops could use what
you've got—" Then he stopped. "It'd never be authorized," he said
bitterly. "They'd never let a cop try it."</p>
<p>"No," agreed Brink. "Until it's believed in it can only be used
privately, for private purposes. Like I've used it. Or Hm-m-m. Do you
fish, or bowl, or play golf, sergeant? I could give you a psi unit
that'd help you quite a bit in such a private purpose."</p>
<p>Detective Sergeant Fitzgerald shook his head.</p>
<p>"Dry-fly fishin's my specialty," he said bitterly, "but no thank you!
When I'm pittin' myself against a trout, it's my private purpose to be a
better fisherman than he's a fish. Usin' what you've got would be like
dynamitin' a stream. No sport in that! No! But this Big Jake, he doesn't
act sporting with the public. I'd give a lot to stop him."</p>
<p>"You'd get no credit for it," said Brink. "No credit at all."</p>
<p>"I'd get the job done!" said Fitzgerald indignantly. "A man likes
credit, but he likes a lot better to get a good job done!"</p>
<p>Brink grinned suddenly.</p>
<p>"Good man!" he said approvingly. "I'll buy your idea, sergeant. If
you'll play fair with a trout, you'll play fair with a crook, and an
Irishman, anyhow, has a sort of inheritance—I'll give you what help I
can, and you'll do things your grandfather would swear was the work of
the Little People. And for a first lesson—"</p>
<p>"What?"</p>
<p>"Big Jake discourages me," said Brink. "So I'll call him up and say I'm
coming to see him. I'll say if he wants this business I'll sell it to
him at a fair price. But I'll say otherwise I'll tell the newspapers
about his threats and the four of his hoods in the hospital and the two
others on the way there. Want to come along?"</p>
<p>Detective Sergeant Fitzgerald reached his hand to where his service
revolver reposed in its holster. Then he drew it away.</p>
<p>"He's a very violent man," he said hopefully. "I wouldn't wonder he
tried to get pretty rough—him and the characters he has on his payroll.
If they have to be stopped from bein' violent by—what is it? Psi units?
Sure I'll come along! It'd ought to be most edifyin' to watch!"</p>
<hr style='width: 45%;' />
<p>There was a clanging outside. Brink and Detective Sergeant Fitzgerald
delayed while the two unnerved, helpless, and formerly immaculate gunmen
were loaded into the paddy-wagon and carried away—to the hospital that
already held four of their ilk. Then Brink called Big Jake on the
telephone.</p>
<p>Detective Sergeant Fitzgerald listened with increasing appreciation as
Brink made his proposition and explained matter-of-factly what had
happened to Big Jake's minions who should have wrecked the Elite
Cleaners and Dyers. When Brink hung up, Fitzgerald had a look of zestful
anticipation on his face.</p>
<p>"He said to come right over," said Brink. "But he was grinding his
teeth."</p>
<p>"Ah-h-h!" said Fitzgerald pleasurably. "I'm thinkin' of the cab-drivers
an' truck drivers that've been beat up. I'm thinkin' of property smashed
and honest people scared.... Do you know, I'm terrible afraid Big Jake's
too much in the habit of violence to stop, even if his eyelids twitch?
It's deplorable! But on a strictly personal basis I think I'll enjoy
seein' Big Jake an' his hoods discouraged by ... what is it Psi units?
Yes!"</p>
<p>And he did. Big Jake's eyelids undoubtedly did twitch while he was
preparing a reception for Brink and Detective Sergeant Fitzgerald. But
he did not heed the warning. He did not even think of the legal aspect
of violent things attempted against his visitors. So he tried
violence—he and his associates. They started out with fists and clubs,
regardless of discretion. They tried to beat up Brink and Fitzgerald.
From that they went on to sawed-off shotguns. Their efforts were still
unsuccessful. Then they went to extremes.</p>
<p>Fitzgerald wore an expression of pious joy as Big Jake Connors and his
aides, obstinately attempting violent actions, were prevented by psi
units.</p>
<p>When it was all over, the ambulance had to make two trips.</p>
