"Kerk must see this book," Jason said. "He should have some idea of the progress being made. Can we get transportation—or do we walk to city hall?"

"Walk, of course," Meta said.

"Then you bring the book. At two G's I find it very hard to be a gentleman and carry the packages."

They had just entered Kerk's outer office when a shrill screaming burst out of the phone-screen. It took Jason a moment to realize that it was a mechanical signal, not a human voice.

"What is it?" he asked.

Kerk burst through the door and headed for the street entrance. Everyone else in the office was going the same way. Meta looked confused, leaning towards the door, then looking back at Jason.

"What does it mean? Can't you tell me?" He shook her arm.

"Sector alarm. A major breakthrough of some kind at the perimeter. Everyone but other perimeter guards has to answer."

"Well, go then," he said. "Don't worry about me. I'll be all right."

His words acted like a trigger release. Meta's gun was in her hand and she was gone before he had finished speaking. Jason sat down wearily in the deserted office.
