"Will the doors hold?"

The Chief's mouth quirked.

"They'll need demolition equipment to break them down," he said. "All these have are heatguns and tear gas. One of the observers farther downtown said he saw a tank heading this way, but if they don't already know there are innocent customers in here, Childress will tell them."

"Then everybody gets away but Childress?"

"We hope. They're not going to ignore these surrounding houses, especially with men drifting out of them and moving away. That's why I want to stress the importance of one thing to you, Kensington: you're too important for us to lose at this juncture, with your knowledge of the original work done. That house at the end of your exit will have a dozen or so of our men in it, waiting to drift away one by one, but you can't afford to worry about them. I want you to get in that groundcar, alone, and take off like Phobos rising."

"You're going out the other emergency exit?"

"That's none of your business. But, as a matter of fact, no. If you want to see something that will throw consternation into this Marscorp outfit, watch the roof of this building. Now, get moving, Kensington, and good luck. Fancher and I will be leaving as soon as he gets all the records packed."

The Chief held out his tiny hand, and Dark shook hands with him. Then Dark left, went down into the basement and entered an underground door in its eastern wall. He had to crawl through the tunnel driven through the sand under the street.

He emerged in the basement of a house across the street, which ostensibly was owned by Manfall Kingron, a retired space engineer. He went upstairs.

About half the personnel of the barber college who had not been caught by the alarm were roaming the rooms of the small house, drifting singly out the back door at ten-minute intervals.
