Dane reached the shaft of the riser—to find the platform gone. Would either Rip or Ali have presence of mind enough to send it down to him on automatic?

"Rip—return the riser," he spoke urgently into the throat mike of his helmet com.

"Keep your rockets straight," Ali's cool voice was in his earphones, "It's on its way down. Did you remember to bring Exhibit A?"

Dane did not answer. For he was very much occupied with another problem. On the bronze doors he had been at such pains to seal shut there had come into being a round circle of dull red which was speedily changing into a coruscating incandescence. They had brought a flamer to bear! It would be a very short time now before the Police could come through. That riser—

Afraid of overbalancing in the bulky suit Dane did not lean forward to stare up into the shaft. But, as his uncertainty reached a fever pitch, the platform descended and he took two steps forward into temporary safety, still clutching the cage. At the first try the thick fingers of his gloved hand slipped from the lever and he hit it again, harder than he intended, so that he found himself being wafted upward with a speed which did not agree with a stomach, even one long accustomed to space flight. And he almost lost his balance when it came to a stop many floors above.

But he had not lost his wits. Before he stepped from the platform he set the dial on a point which would lift the riser to the top of the shaft and hold it there. That might trap the Traders on the broadcasting floor, but it would also insure them time before the forces of the law could reach them.

Dane located the rest of his party in the circular core chamber of the broadcasting section. He recognized a backdrop he had seen thousands of times behind the announcer who introduced the news-casts. In one corner Rip, his suit off, was working over the still relaxed form of the Medic. While Ali, a grim set to his mouth, was standing with a man who wore the insignia of a Com-tech.

"All set?" Rip looked up from his futile ministrations.

Dane put down the cage and began the business of unhooking his own protective covering. "They were burning through the outer doors of the entrance hall when I took off."

"You're not going to get away with this—" that was the Com-tech.
