She sniffled. "If I could just feel warm again—if you would build a fire and give me a chance to rest—"

"Not until we're inside the barrier. The police would spot a fire out here."

Gill picked her up and began to carry her toward the beach. She screamed in terror and beat her fists against his naked back. When he did not stop, she cried out,

"I can tell you how to break the circuit on the pylons!"

Gill paused. "Yes?"

"If we could knock out just one of the guns, we could walk through the barrier, couldn't we?"

Gill set her on her feet. She ran back to Lanny, stumbling over the rough ground and wiping her nose with the back of her hand. "Lanny, you and your brother can hit anything with a stone. Couldn't you knock out the power unit in a pylon?"

"Sure, if we knew where it was. We've tried for years to find that out, but we can't get close enough to examine the towers."

She pointed eagerly. "It's the criss-crossed framework, just under the sound receptor at the top."

He measured the distance critically. "It will take careful marksmanship to hit anything so small. Think we could do it, Gill?"
