A few seconds later, Fry said, "All right. You're off the record."

"Most of what I told you was the truth," Camhorn said, leaning back in

his chair. "Perhaps not all of it. And perhaps I haven't told you the

whole truth. But we're out to spread some plausible rumors, Gus. We

could not afford to get caught in obvious lies."

Fry reddened slowly. "You feel the Interstellar Police Authority will

spread those rumors?"

"Of course it will. Be realistic, Gus. Naturally, you'll transmit the

information I've given you only to qualified personnel. But there'll be

leaks, and ... well, what better authentication can we have for a rumor

than precisely such a source?"

"If you know of any potential leaks among the IPA's 'qualified

personnel,'" Fry said, "I'd appreciate seeing the names."

"Don't be stuffy, Gus," Camhorn said affably. "We're not slandering the

Authority. We're banking on the law of averages. As you've indicated,

the IPA can't be expected to carry out this investigation unless it's

given some clues to work on. We're giving it those clues. In the

process, we expect to start the spread of certain rumors. That's all to

the good."

"But what's the purpose?"

"I've told you that. Our criminals may or may not be caught as quickly

as we'd like. The group actually in the know may be--probably

is--quite small. But they should have a wide-spread organization, and

they'll be alert for counteraction now. They certainly will get the

information we want them to have, whether it comes to them through the

IPA or through some other channel; and that should be enough to keep

them from committing any obvious stupidities. Meanwhile, we'll have

avoided making the information public.

"We want to make sure they know--if they don't already know it--that

Ym-400 is unpredictably dangerous. That leaves them with several

choices of action. They can abandon those two thirty-four kilogram

cases, or simply keep them concealed until they obtain more complete

information about the material. Considering the manner in which the

theft was prepared and carried out, neither is a likely possibility.

These people are not ignorant, and they aren't easily frightened--and

they certainly have the resources to handle any expense factor."

Fry nodded.

"The probability is," Camhorn went on, "that they'll evaluate the

warning contained in these rumors realistically, but proceed with

experimentation--perhaps more cautiously than they would have done

otherwise.

"Which is as much as we hope to accomplish. I've told you of the losses

among our personnel. We have no real objection to seeing someone else

attempt to pull a few chestnuts out of the fire for us. That's the

secondary purpose of sacrificing some quite valid information. By the

time we catch up with our friends, we expect the sacrifice will have

been--in one way or another--to our advantage."

"And suppose," said Fry, "that their secret experiments with Ym-400

result in turning another planet into an asteroid cloud?"

"That's an extreme possibility," Camhorn said, "though it exists. The

point is that it exists now whatever we choose to do about it. We can

only attempt to minimize the risks."

"You'd still sooner catch them before they start playing around with

the stuff?"

"Of course we would. But we're working against time there."

* * * * *

"How much time do we have before the thing gets critical?"

"Well," said Camhorn, "assume they've had at least four or five years

to prepare for the day when they could bring a quantity of Ym-400

into their possession. They'll have made every necessary arrangement

for concealed full-scale experimentation. But, unless they are

utterly reckless, they still have to conduct a thorough preliminary

investigation of the compound and its possibilities. That phase of the

matter shouldn't be too dangerous, and it can't be concluded in less

than six months."

Fry shook his head exasperatedly. "Six months!" he said. "We might get

lucky and pick them up next week, Howard ... but there are eighteen

planets and planet-class satellites at peak population levels,

seventy-three space cities with a total of eight times the planetary

populations, five Freeholder planets on each of which you could keep

an army concealed indefinitely if you wanted to go to the trouble. Add

in close to a hundred thousand splinter populations on semihabitables,

asteroids, spaceborne in fixed stations and mobile craft--we can't do

it, Howard! Not in six months. We've already started putting anyone

who might have the slightest connection with that space transport job

through the strainer, and we'll get on your lists of suspects as soon

as they're placed in our hands.

"But don't expect results in anything less than a year...."

* * * * *

Fry, for once, had been too optimistic.

A year and a half went by. Endless series of more or less promising

leads were run into the ground. The missing Ym-400 didn't turn up.

The IPA put out its nets again, and began to check over the

possibilities that were left.

* * * * *

Seen from the air, Lion Mesa, in the southwest section of the American

continent on the Freehold Planet of Terra, was a tilted, roughly

triangular table-land, furred green with thick clusters of cedar and

pinyon, scarred by outcroppings of naked rock. It was eight miles

across at its widest and highest point, directly behind an upthrust

mass of stone jutting toward the north and somewhat suggestive of the

short lifted neck and heavy skull of a listening beast. Presumably it

was this unusual formation which gave the mesa its name. From there the

ground dropped to the south, narrowing gradually to the third point of

the triangle. Near the southern tip in cleared ground were the only

evidences of human habitation--half a dozen buildings of small to

moderate size, handsomely patterned in wood and native stone. Directly

adjoining one of the buildings was a large, massively fenced double

corral. This was an experimental animal ranch; it and the mesa plus

half a hundred square miles of surrounding wasteland and mountain were

the private property of one Miguel Trelawney, Terrestrial Freeholder.

For the past twenty minutes, Frank Dowland--Lieutenant Frank Dowland,

of the Solar Police Authority--had kept his grid-car moving slowly

along the edges of a cloud bank west of the mesa, at an unobtrusive

height above it. During that time, he was inspecting the ranch area in

the beam of a high-powered hunting-scope. He had detected no activity,

and the ranch had the general appearance of being temporarily deserted,

which might be the case. Miguel Trelawney's present whereabouts were

not known, and Lion Mesa was only one of the large number of places in

which he was periodically to be found.

Dowland put the scope down finally, glanced at the sun which was

within an hour of setting. He was a stocky man in his early thirties,

strongly built, dressed in hunting clothes. The packed equipment in the

grid-car, except for a few special items, was that of a collector of

live game, the role regularly assumed by Dowland when at work on the

planet. The Freeholder Families traditionally resented any indication

of Overgovernment authority on Terra, and would have been singularly

uncordial to a Solar City police detective here, regardless of the

nature of his mission. But the export of surplus native fauna was one

of the forms of trade toward which they were tolerant. Moreover, they

were hunting buffs themselves. Dowland ordinarily got along well enough

with them.

He now opened a concealed compartment in the car's instrument panel,

and brought out a set of pictures of Trelawney's ranch on the mesa,

taken from an apparent distance of a few hundred yards above it. For

some seconds, Dowland compared the depth photographs with the scene he

had been observing. There appeared to have been no changes in any of

the structures in the eight months since the pictures were taken. At

least not above ground.

Dowland rubbed the side of his nose, scowling slightly. If the ranch

really was deserted, it would be best to leave it alone for the time

being and search elsewhere for Trelawney. To go down uninvited in

the absence of the owner would be as much out of character for an

experienced visitor on Terra as for a Freeholder. If observed at it--a

remote possibility perhaps in this area, but the possibility was

there--he could offer the excuse of a suspicion of engine trouble in

the grid-car. The excuse would be good, once. He preferred to reserve

it as a means of introducing himself to the Trelawneys when he caught

up with them--either Miguel, the current head of the dwindled family,

or Miguel's younger half-brother, Dr. Paul Trelawney. Neither rated as

a serious suspect in the matter of the Overgovernment's missing Ym-400,

but it had been a little difficult to find out what they had been doing

with themselves during the past year and a half. Dowland's assignment

was to find out, and to do it unobtrusively. Strictly routine.

* * * * *

Terra, in terms of the YM search, hadn't seemed like too bad a bet

at first. The Freeholders entertained an open grudge against the

Overgovernment, which had restricted their nominally unclouded title

to the planet by somewhat underhanded legal means, when the principle

of the Freehold Worlds was laid down. Essentially, the Families became

the very highly paid caretakers of Terra. To Dowland, raised in the

crowded tunnels of the system of artificial giant asteroids known as

Solar City, the conservation of the natural resources of a living

world looked like a good idea. The Terran Families were interested

in conservation, but on their terms and under their control. The

Overgovernment politely refused.

That was one part of it. The other was that numerous contentious

factions in the space cities and on the so-called open worlds wanted

to spill over on the Freeholder planets. Again the Overgovernment

refused, and again it made sense to Dowland. But the Freeholders

feared--perhaps with justification, so far as Dowland could tell--that

political pressures would mount with each increase in excess population

and eventually lead to such measures. Many of them, probably the

majority, led by Anthony Brand Carter--Firebrand Carter, head of the

largest and wealthiest of the Families--believed that the only safe

solution was to arm the planet. They wanted heavy weapons, and enough

of them: the right to build them, to man them and, if necessary, to

use them to beat off encroaching groups. The Overgovernment pointed

out that the possession and use of major implements of war was by law

its own exclusive privilege. Litigation on the matter had gone on

for decades, was periodically renewed by Carter and his associates.

Meanwhile, many of Terra's sportsmen became members of an extremely

able-bodied group called Carter's Troopers, and assiduously practiced

the skills of battle with the means allowed them. Dowland and the Solar

Police Authority knew the Troopers were crack shots, excellent fliers

and horsemen, but the Overgovernment was not worrying about it at

present.

Mr. Paul Trelawney, the younger of the brothers, had been a Trooper

for two years while in his twenties, then had quarreled violently

with Firebrand Carter, had left Terra to major in physics at the

Overgovernment's universities, and presently received his degree.

What he had done after that wasn't known. He appeared occasionally

on Terra, might be here at present. Miguel, Paul's senior by almost

twenty years, now in his early fifties, had also taken an interest in

physics, attending an Overgovernment university a quarter of a century

earlier. Miguel's studies terminated before he obtained a degree,

as a result of a difference of opinion with the president of the

university, whom he challenged to a duel. The records of both brothers

indicated, in Dowland's opinion, more than a trace of the megalomania

not too uncommon among men with excessive wealth and no real claim

to distinction. But, in spite of their choice of studies, there was

nothing to link either Trelawney to the missing YM. Mental brilliance

might have made them suspect; but their I.Q. readings, while definitely

better than average--a number of notches above Dowland's own, for

that matter--were not outstanding. Their scholastic performance had

been of comparative quality. Miguel, on his return to Terra, had

dropped physics in favor of experimental biology. The ranch on Lion

Mesa was adapted to his hobby, which at the moment was directed to the

production of a strain of gigantic wild hogs for hunting purposes.

Presumably the breeding of bad-tempered tons of bacon on the hoof

satisfied his urge to distinguish himself as a gentleman scientist.

Aside from Paul's brief connection with Carter's Troopers neither

brother had shown any interest in Terran politics.

* * * * *

Rather poor prospects, but Dowland's information was that after a year

and a half the better prospects were regarded as nearly exhausted, and

hadn't produced the slightest results, putting the various divisions

of the Interstellar Police Authority in the discouraging position of

now having to suspect almost anybody. If there was no sign of Miguel

Trelawney's presence here by sundown, he decided, he would move on to

the next check point. Trelawney's pets would be cared for by automatic

machinery; it might be several weeks before their owner showed up to

look them over.

His gaze shifted briefly around the plain out of which the mesa loomed.

It was turbulent today; gusty winds shook the car and electric storms

were boiling along the northern mountain ranges. Below, sand and dust

whirled up the mesa's steep flanks. Picking up the hunting-scope

again, Dowland began moving the visibeam almost at random and with low

magnification over the back of the table-land. Dense masses of trees

swept past, shouldered aside here and there by wind-scarred rock. A

thoroughly wild place. He brought the glasses back to the ranch area,

suddenly checked them there....

Somebody was in sight, moving toward the edge of the mesa nearest

him. He caught a flash of something white. Centering carefully on the

figure, Dowland turned on full magnification, and in the lenses, the

image of a young woman appeared at close-up range.

She had come to a stop; and for an instant Dowland was startled to

realize she was peering back at him through a pair of binoculars. But

lacking the visibeam of the IPA, her glasses couldn't, of course, do

much more than show her there was a grid-car up there. Now her free

hand lifted the long white cloth it was holding, and began swinging it

in swift, vigorous gestures through the air above her head.

In spite of the binoculars, Dowland was immediately sure of the woman's

identity--having, in the past few days, studied a number of pictures

of her. She was Jill Trelawney, the youngest of the three surviving

members of the Trelawney Freeholders. Miguel and Paul were her

uncles--and if she was here, one or the other of the men must certainly

be here also.

It was obvious that she was signaling to the car. Dowland glanced at

the communicator in the panel before him, saw it was turned on but

registering no local calls. His eyes narrowed with speculation. This

suddenly looked just a little bit interesting. If the Trelawneys were

expecting a visitor but preferred not to address him over the open

communication system, it indicated that they intended to be hard to

find.

Which might mean a number of things of no interest at all to the IPA.

But....

Dowland took his police gun from the pocket of his hunting jacket, and

began checking it by touch, as he swung the car's nose about toward the

ranch and went slanting down toward the air. Either of the brothers

might decide to make trouble, particularly if they had something to

conceal--but, at any rate, they couldn't claim he hadn't been invited

down.

Picking up the girl in the scope again, he saw that she realized he was

coming in. She had dropped the cloth but was still gazing up toward

the car, her free hand shielding her eyes from the setting sun.

In the next instant, without the slightest preliminary warning, every

instrument in the panel before Dowland went dead. Then the grid-car

began to drop like a stone.

* * * * *

The world-wide gravity grid was Terra's general power source. It had

been an idiotically expensive installation; actually, no other planet

could have afforded it at present. Once installed, it was drawn on for

idiotically minor services. There weren't enough human beings on Terra

to begin to make a significant use of the grid.

But, there were compensating features. The grid was esthetically

unobtrusive, and available everywhere. It supplied power for anything

from personal wrist watches on up through the giant docking machines at

the space-ports. And it was reliable. There had been no power failures

and no accidents connected with the grid recorded in its eighty years

of operation.

That shining safety record, Dowland thought, manipulating the flight

controls with desperate haste, might become seriously marred in

something like three-quarters of a minute now. He'd be lucky to get

down alive. And another thought was clamoring for a different kind of

action with almost equal urgency--unusual and unexplained physical

phenomena of any kind were one of the things the YM searchers were

alerted to look out for; and he'd certainly run into one of them here.

He shot a glance down to his camouflaged wrist communicator. Just a few

seconds to spare, and he could get a private-beam alarm in to the Solar

Police Authority representative at the Columbia spaceport.

He didn't have a few seconds to spare. The grid-car was a lousy

glider--ponderous, sickeningly slow to respond. The rim of the mesa

swayed up. If he missed that stretch of cleared ground around the

Trelawney ranch, the car would either tear itself to pieces in the

forest beyond or do a ditch into the piled rubble at the mesa's foot.

He hauled back on the controls again, felt the car actually begin to

rise for an instant--

* * * * *

"I'm sorry," Jill Trelawney was crying, running up the slope toward

him. "I'm so terribly sorry. I tired to warn you. I simply didn't

realize--are you hurt?"

Her face, Dowland thought, was probably no whiter than his own. The

canopy had caved in around him, and a jagged chunk of engine was

nestling in the passenger seat to his right. As he tried to stand up,

a section of the plastic floorboard collapsed; his foot followed it

through and struck solid ground. He worked himself out of the seat. The

grid-car creaked tiredly and settled another six inches. Dowland shoved

a piece of canopy aside and found he could straighten out.
