He snapped off a twig. It was brittle, easy to break. Of course, the Roller might have been faking deliberately but he didn’t think so. On the other hand, where was it vulnerable? How would he go about killing it if he got the chance? He went back to studying it. The outer hide looked pretty tough; he’d need a sharp weapon of some sort. He picked up the piece of rock again. It was about twelve inches long, narrow, and fairly sharp on one end. If it chipped like flint, he could make a serviceable knife out of it.
The Roller was continuing its investigations of the bushes. It rolled again, to the nearest one of another type. A little blue lizard, many-legged like the one Carson had seen on his side of the barrier, darted out from under the bush.
A tentacle of the Roller lashed out and caught it, picked it up. Another tentacle whipped over and began to pull legs off the lizard, as coldly as it had pulled twigs off the bush. The creature struggled frantically and emitted a shrill squealing that was the first sound Carson had heard here, other than the sound of his own voice.
Carson made himself continue to watch; anything he could learn about his opponent might prove valuable, even knowledge of its unnecessary cruelty—particularly, he thought with sudden emotion, knowledge of its unnecessary cruelty. It would make it a pleasure to kill the thing, if and when the chance came.
With half its legs gone, the lizard stopped squealing and lay limp in the Roller’s grasp.
It didn’t continue with the rest of the legs. Contemptuously it tossed the dead lizard away from it, in Carson’s direction. The lizard arced through the air between them and landed at his feet.
It had come through the barrier! The barrier wasn’t there any more! Carson was on his feet in a flash, the knife gripped tightly in his hand, leaping forward. He’d settle this thing here and now! With the barrier gone—but it wasn’t gone. He found that out the hard way, running head on into it and nearly knocking himself silly. He bounced back and fell.
As he sat up, shaking his head to clear it, he saw something coming through the air towards him, and threw himself flat again on the sand, to one side. He got his body out of the way, but there was a sudden sharp pain in the calf of his left leg.
He rolled backwards, ignoring the pain, and scrambled to his feet. It was a rock, he saw now, that had struck him. And the Roller was picking up another, swinging it back gripped between two tentacles, ready to throw again.
It sailed through the air towards him, but he was able to step out of its way. The Roller, apparently, could throw straight, but neither hard nor far. The first rock had struck him only because he had been sitting down and had not seen it coming until it was almost upon him.
