"What did go on there?" Vall asked. "Ask them about recent improvements, new buildings, new fields cleared, new paddies flooded, that sort of thing. And pick out a few of the highest IQ's from both time lines, and have them locate this estate on a large-scale map, and draw plans showing the location of buildings, fields and other visible features. If you have to, teach them mapping and sketching by hypno-mech. And then drop about five hundred to a thousand boomerang balls, at regular intervals, over the whole paratemporal area. When you locate a time line that gives you a picture to correspond to their description, boomerang the main square in Sohram over the whole belt around it, to find Croutha with firearms." The deputy looked at him for a moment then gulped more coffee. "Can do, Assistant Verkan. I think I'll send somebody to wake up Subchief Ranthar, right now. Want to talk to him." "Won't be necessary. You're recording this call, of course? Then play it back to him. And get cracking with the slaves; you want enough information out of them to enable you to start boomerang balling as soon as the sun's high enough." * * * * * He broke off the connection and sent out for coffee for himself. Then he put through a call to Novilan Equivalent, in western North America. It was 1530, there, when he got Vulthor Tharn on the screen. "Good afternoon. Assistant Verkan. I suppose you're calling about the slave business. I've turned the entire matter over to Field Agent Skordran; gave him a temporary rank of Deputy Subchief. That's subject to your approval and Chief Tortha's, of course--" "Make the appointment permanent," Vall said. "I'll have a confirmation along from Chief Tortha directly. And let me talk to him now, if you please. Subchief Vulthor." "Yes, sir. Switching you over now." The screen went into a beautiful burst of abstract art, and cleared, after a while, with Skordran Kirv looking out of it. "Hello, Deputy Skordran, and congratulations. What's come up since we had Nebu-hin-Abenoz cut out from under us?" "We went in on that time line, that same night, with an airboat and made a recon in the hills back of Careba. Scared the fear of Safar into a party of Caleras while we were working at low altitude, by the way. We found the conveyer-head site: hundred-foot circle with all the grass and loose dirt transposed off it and a pole pen, very unsanitary where about two-three hundred slaves would be kept at a time. No indications of use in the last ten days. We did some pretty thorough boomeranging on that spatial equivalent over a couple of thousand time lines and found thirty more of them. I believe the slavers have closed out the whole Esaron Sector operation, at least temporarily." That was what he'd been afraid of; he hoped they wouldn't do the same thing on the Kholghoor Sector. "Let me have the designations of the time lines on which you found conveyer heads," he said.
