"Hello, Assistant Verkan," a voice came out of the speaker under the screen, as the man moved his lips. "Deputy Skordran! Here's Chief's Assistant Verkan, now!"

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

"Hello, 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 passed into another space-time continuum, even into another kind of space-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 spacesuit was the only protection. One of the detectives helped him on with his metal and plastic armor; before sealing his gauntlets, he reciprocated the assistance, 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 spacesuits 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.
