The skimmer slowed, climbing up the beam of light.

A resurgence of panic took hold of Wyatt. "Why Alpha Centauri? Why do I have to go there?"

"Two reasons. We work well ahead, always planning the next campaign before we finish the last one. I told you they'll question you. In the normal course of events you would be shown the Centauri campaign so that you could get a clear idea of just how we work, and then you would be used to persuade your people not to resist."

"But you'll arrange my escape before that."

"I'll do what I can," she snapped, "as long as you keep your mouth shut. Now we're going in, and from here on you're just another captive."

Wyatt looked at her. He didn't trust her promise, not at all. He thought he had better never trust this dark girl too far.

The skimmer rose up into a great hatch. Wyatt heard a thunderous click transmitted through the air in the cockpit and felt a strong jar as what he thought must be a magnetic grapple took hold. Beyond the window now he saw a brightly lighted space that looked as big as Grand Central, equipped with great incomprehensible pieces of machinery. None of them looked like any propulsion or communication machines he knew. How did a faster-than-light ship communicate, anyway? An idea came to him.

Small figures moved out there. He recognized them as men wearing spacesuits. The suits were astonishingly like those being tested by the Air Force for high-altitude flying. He thought the A.F. boys would be glad to know their designs were good.

The skimmer was dormant, being lifted and handled by forces outside. Brinna said, "We have to wait for pressure to build up."

The huge hatch doors beneath had closed. Presently Wyatt heard sounds faintly from outside the skimmer, chiefly a throbbing noise like the beating of a gigantic heart which he thought must be the air-pumps.
