"I thought you"d managed to get that blabbermouth transposed to PolTerm," Zostha said.

"He wouldn"t go." Tortha Karf replied. "Said it was just a trick to get him off Home Time Line during the Council crisis."

Yandar Yadd had appeared on the screen as the pickup swung about.

"... Recording ostensibly made by Councilman Salgath on Police Terminal Time Line, and telecast on Home Time Line an hour ago. Well, I don"t know who he was, but I now have positive proof that he definitely was not Salgath Trod!"

"We"re sunk!" Zostha Olv grunted. "He"d never make a statement like that unless he could prove it."

"... Something suspicious about the whole thing, from the beginning,"

the newsman was saying. "So I checked. If you recall, the actor impersonating Salgath gestured rather freely with his hands, in imitation of a well-known mannerism of the real Salgath Trod; at one point, the ball of his right thumb was presented directly to the pickup. Here"s a still of that scene."

He stepped aside, revealing a viewscreen behind him; when he pressed a b.u.t.ton, the screen lighted; on it was a stationary picture of Kostran Galth as Salgath Trod, his right hand raised in front of him.

"Now watch this. I"m going to step up the magnification, slowly, so that you can be sure there"s no subst.i.tution. Camera a little closer, Trath!"

The screen in the background seemed to advance, until it filled the entire screen. Yandar Yadd was still talking, out of the picture; a metal-tipped pointer came into the picture, touching the right thumb, which grew larger and larger until it was the only thing visible.

"Now here," Yandar Yadd"s voice continued. "Any of you who are familiar with the ancient science of dactyloscopy will recognize this thumb as having the ridge-pattern known as a "twin loop." Even with the high degree of magnification possible with the microgrid screen, we can"t bring out the individual ridges, but the pattern is unmistakable. I ask you to memorize that image, while I show you another right thumb print, this time a certified photo-copy of the thumb print of the real Salgath Trod." The magnification was reduced a little, a card was moved into the picture, and it was stepped up again. "See, this thumb print is of the type known as a "tented arch."

Observe the difference."

"That does it!" Zostha Olv cried. "Karf, for the first and last time, let me remind you that I opposed this lunacy from the beginning. Now, what are we going to do next?"

"I suggest that we get to Headquarters as soon as we can," Tortha Karf said. "If we wait too long, we may not be able to get in."

Yandar Yadd was back on the screen, denouncing Tortha Karf pa.s.sionately. Tortha went over and snapped it off.

"I suggest we transpose to PolTerm," Lovranth Rolk said. "It won"t be so easy for them to serve a summons on us there."

"You can go to PolTerm if you want to," Tortha Karf retorted. "I"m going to stay here and fight back, and if they try to serve me with a summons, they"d better send a robot for a process server."

"Fight back!" Zostha Olv echoed. "You can"t fight the Council and the whole Management! They"ll tear you into inch bits!"

"I can hold them off till Vall"s able to raid those Abzar Sector bases," Tortha Karf said. He thought for a moment. "Maybe this is all for the best, after all. If it distracts the Organization"s attention--"

"I wish we could have made a boomerang-ball reconnaissance," Ranthar Jard was saying, watching one of the viewscreens, in which a film, taken from an airboat transposed to an adjoining Abzar sector time line, was being shown. The boat had circled over the Ganges, a mere trickle between wide, deeply cut banks, and was crossing a gullied plain, spa.r.s.ely grown with thornbush. "The base ought to be about there, but we have no idea what sort of changes this gang has made."

"Well, we couldn"t: we didn"t dare take the chance of it being spotted. This has to be a complete surprise. It"ll be about like the other place, the one the slaves described. There won"t be any permanent buildings. This operation only started a few months ago, with the Croutha invasion; it may go on for four or five months, till the Croutha have all their surplus captives sold off. That country,"

he added, gesturing at the screen, "will be flooded out when the rains come. See how it"s suffered from flood-erosion. There won"t be a thing there that can"t be knocked down and transposed out in a day or so."

"I wish you"d let me go along," Ranthar Jard worried.

"We can"t do that, either," Vall said. "Somebody"s got to be in charge here, and you know your own people better than I do. Beside, this won"t be the last operation like this. Next time, I"ll have to stay on Police Terminal and command from a desk; I want first-hand experience with the outtime end of the job, and this is the only way I can get it."

He watched the four police-girls who were working at the big terrain board showing the area of the Police Terminal time line around them.

They had covered the miniature buildings and platforms and towers with a fine mesh, at a scale-equivalent of fifty feet; each intersection marked the location of a three-foot conveyer ball, loaded with a sleep-gas bomb and rigged with an automatic detonator which would explode it and release the gas as soon as it rematerialized on the Abzar Sector. Higher, on stiff wires that raised them to what represented three thousand feet, were the disks that stood for ten hundred-foot conveyers; they would carry squads of Paratime Police in aircars and thirty-foot air boats. There was a ring of big two-hundred-foot conveyers a mile out; they would carry the armor and the airborne infantry and the little two-man scooters of the air-cavalry, from the Service and Industrial Sectors. Directly over the spatial equivalent of the Kholghoor Sector Wizard Traders"

conveyers was the single disk of Verkan Vall"s command conveyer, at a represented five thousand feet, and in a half-mile circle around it were the five news service conveyers.

"Where"s the ship-conveyer?" he asked.

"Actually it"s on antigrav about five miles north of here," one of the girls said. "Representationally, about where Subchief Ranthar"s standing."

Another girl added a few more bits to the network that represented the sleep-gas bombs and stepped back, taking off her earphones.

"Everything"s in place, now, a.s.sistant Verkan," she told him.

"Good. I"m going aboard, now," he said. "You can have it, Jard."

He shook hands with Ranthar Jard, who moved to the switch which would activate all the conveyers simultaneously, and accepted the good wishes of the girls at the terrain board. Then he walked to the mesh-covered dome of the hundred-foot conveyer, with the five news service conveyers surrounding it in as regular a circle as the buildings and towers of the regular conveyer heads would permit. The members of his own detail, smoking and chatting outside, saw him and started moving inside; so did the news people. A public-address speaker began yelping, in a hundred voices all over the area, warning those who were going with the conveyers to get aboard. He went in through a door, between two aircars, and on to the central control-desks, going up to a visiscreen over which somebody had crayoned "Novilan EQ." It gave him a view, over the shoulder of a man in the uniform of a field agent third cla.s.s, of the interior of a conveyer like his own.

"h.e.l.lo, a.s.sistant Verkan," a voice came out of the speaker under the screen, as the man moved his lips. "Deputy Skordran! Here"s Chief"s a.s.sistant Verkan, now!"

Skordran Kirv moved in front of the screen as the operator got up from his stool.

"h.e.l.lo, Vall; we"re all set to move out as soon as you give the word,"

he said. "We"re all in position on antigrav."

"That"s smart work. We"ve just finished our gas-bomb net," Vall said.

"Going on antigrav now," he added, as he felt the dome lift. "I hope you won"t be too disappointed if you draw a blank on your end."

"We realize that they"ve closed out the whole Esaron Sector," Skordran Kirv, eight thousand odd miles away, replied. "We"re taking in a couple of ships; we"re going to make a survey all up the coast. There are a lot of other sectors where slaves can be sold in this area."

In the outside viewscreen, tuned to a slowly rotating pickup on the top of a tower spatially equivalent with a room in a tall building on Second Level Triplanetary Empire Sector, he could see his own conveyer rising vertically, with the news conveyers following, and the troop conveyers, several miles away, coming into position. Finally, they were all placed; he reported the fact to Skordran Kirv and then picked up a hand-phone.

"Everybody ready for transposition?" he called. "On my count. Thirty seconds ... Twenty seconds ... Fifteen seconds ... Five seconds ...

Four seconds ... Three seconds ... Two seconds ... One second, _out!_"

All the screens went gray. The inside of the dome pa.s.sed into another s.p.a.ce-time continuum, even into another kind of s.p.a.ce-time. The transposition would take half an hour; that seemed to be the time needed to build up and collapse the transposition field, regardless of the paratemporal distance covered. The dome above and around them vanished; the bare, tower-forested, building-dotted world of Police Terminal vanished, too, into the uniform green of the uninhabited Fifth Level. A planet could take pretty good care of itself, he thought, if people would only leave it alone. Then he began to see the fields and villages of Fourth Level. Cities appeared and vanished, growing higher and vaster as they went across the more civilized Third Level. One was under air attack--there was almost never a paratemporal transposition which did not run through some scene of battle.

He unbuckled his belt and took off his boots and tunic; all around him, the others were doing the same. Sleep-gas didn"t have to be breathed; it could enter the nervous system by any orifice or lesion, even a pore or a scratch. A s.p.a.cesuit was the only protection. One of the detectives helped him on with his metal and plastic armor; before sealing his gauntlets, he reciprocated the a.s.sistance, then checked the needler and blaster and the long batonlike ultrasonic paralyzer on his belt and made sure that the radio and sound-phones in his helmet were working. He hoped that the frantic efforts to gather several thousand s.p.a.cesuits onto Police Terminal from the Industrial and Commercial and Interplanetary Sectors hadn"t started rumors which had gotten to the ears of some of the Organization"s ubiquitous agents.

The country below was already turning to the parched browns and yellows of the Abzar Sector. There was not another of the conveyers in sight, but electronic and mechanical lag in the individual controls and even the distance-difference between them and the central radio control would have prevented them from going into transposition at the same fractional microsecond. The recon-details began piling into their cars. Then the red light overhead winked to green, and the dome flickered and solidified into cold, inert metal. The screens lighted up again, and Vall could see Skordran Kirv, across Asia and the Pacific, getting into his helmet. A dot of light in the center of the underview screen widened as the mesh under the conveyer irised open around the pickup.

Below, the Organization base--big rectangles of fenced slave pens, with metal barracks inside; the huge circle of the Kholghoor Sector conveyer-head building, and a smaller structure that must house conveyers to other Abzar Sector time lines; the work-shops and living quarters and hangars and warehouses and docks--was wreathed in white-green mist. The ring of conveyers at three thousand feet were opening and spewing out aircars and airboats, farther away, the greater ring of heavy conveyers were unloading armored and shielded combat-craft. An aircar which must have been above the reach of the gas was streaking away toward the west, with three police cars after it. As he watched, the air around it fairly sizzled blue with the rays of neutron disruption blasters, and then it blew apart. The three police cars turned and came back more slowly. The three-thousand-ton pa.s.senger ship which had been hastily fitted with armament was circling about; the great dock conveyer which had brought it was gone, transposed back to Police Terminal to pick up another ship.

He recorded a message announcing the arrival of the task-force, pulled out the tape and sealed it in a capsule, and put the capsule in a mesh message ball, attaching it to a couple of wires and flipping a switch.

The ball flashed and vanished, leaving the wires cleanly sheared off.

When it got back to Police Terminal, half an hour later, it would rematerialize, eject a parachute, and turn on a whistle to call attention to itself. Then he sealed on his helmet, climbed into an aircar, and turned on his helmet-radio to speak to the driver. The car lifted a few inches, floated out an open port, and dived downward.
