the thrust. She returned to the window, wriggled feet foremost through the opening, twisted around and got a footing on the ledge.

A minute later, she was scrambling quietly down a vine-covered patio trellis to the ground. Even after they discovered she was gone, the guard screen would keep everybody in the house for some little while. They'd either have to disengage the screen's main mechanisms and start poking around in them, or force open the door to her bedroom and get the lock unset. Either approach would involve confusion, upset tempers, and generally delay any organized pursuit.

Telzey edged around the patio and started towards the wall, keeping close to the side of the house so she couldn't be seen from the windows. The shrubbery made minor rustling noises as she threaded her way through it ... and then there was a different stirring which might have been no more than a slow, steady current of air moving among the bushes behind her. She shivered involuntarily but didn't look back.

She came to the wall, stood still, measuring its height, jumped and got an arm across it, swung up a knee and squirmed up and over. She came down on her feet with a small thump in the grass on the other side, glanced back once at the guest house, crossed a path and went on among the park trees.

Within a few hundred yards, it became apparent that she had an escort. She didn't look around for them, but spread out to right and left like a skirmish line, keeping abreast with her, occasional shadows slid silently through patches of open, sunlit ground, disappeared again under the trees. Otherwise, there was hardly anyone in sight. Port Nichay's human residents appeared to make almost no personal use of the vast parkland spread out beneath their tower apartments; and its traffic moved over the airways, visible from the ground only as rainbow-hued ribbons which bisected the sky between the upper tower levels. An occasional private aircar went by overhead.

Wisps of thought which were not her own thoughts flicked through Telzey's mind from moment to moment as the silent line of shadows moved deeper into the park with her. She realized she was being sized up, judged, evaluated again. No more information was coming through; they had given her as much information as she needed. In the main perhaps, they were simply curious now. This was the first human mind they'd been able to make heads or tails of, and that hadn't seemed deaf and silent to their form of communication. They were taking time out to study it. They'd been assured she would have something of genuine importance to tell them; and there was some derision about that. But they were willing to wait a little, and find out. They were curious and they liked games. At the moment, Telzey and what she might try to do to change their plans was the game on which their attention was fixed.

Twelve minutes passed before the talker on Telzey's wrist began to buzz. It continued to signal off and on for another few minutes, then stopped. Back in the guest house they couldn't be sure yet whether she wasn't simply locked inside her room and refusing to answer them. But Telzey quickened her pace.

The park's trees gradually became more massive, reached higher above her, stood spaced more widely apart. She passed through the morning shadow of the residential tower nearest the guest house, and emerged from it presently on the shore of a small lake. On the other side of the lake, a number of dappled grazing animals like long-necked, tall horses lifted their heads to watch her. For some seconds they seemed only mildly interested, but then a breeze moved across the lake, crinkling the surface of the water, and as it touched the opposite shore, abrupt panic exploded among the grazers. They wheeled, went flashing away in effortless twenty-foot strides, and were gone among the trees.

Telzey felt a crawling along her spine. It was the first objective indication she'd had of the nature of the company she had brought to the lake, and while it hardly came as a surprise, for a moment her urge was to follow the example of the grazers.

"Tick-Tock?" she whispered, suddenly a little short of breath.

A single up-and-down purring note replied from the bushes on her right. TT was still around, for whatever good that might do. Not too much, Telzey thought, if it came to serious trouble. But the knowledge was somewhat reassuring ... and this, meanwhile, appeared to be as far as she needed to get from the guest house. They'd be looking for her by aircar presently, but there was nothing to tell them in which direction to turn first.

She climbed the bank of the lake to a point where she was screened both by thick, green shrubbery and the top of a single immense tree from the sky, sat down on some dry, mossy growth, took the law library from her belt, opened it and placed it in her lap. Vague stirrings indicated that her escort was also settling down in an irregular circle about her; and apprehension shivered on Telzey's skin again. It wasn't that their attitude was hostile; they were simply overawing. And no one could predict what they might do next. Without looking up, she asked a question in her mind.

"Ready?"
