Alcatraz of the Starways by Henry Hasse

It was night, and the overhead lights in the corridors were dimmed. Ernest Carston tossed restlessly in his bed. He could not sleep, he had been unable to sleep since seeing and hearing the Earth Council on the ethero-magnum.

Carston arose, and dressed quickly. Silently he crossed the room to the outer door, and stepped out into the corridor. He paced slowly, aimlessly, his brow knit in deep thought. Finally he made a decision, and turned his footsteps in the direction of the palace and the laboratory. He was still an Earth official; he had known all the time that he would have to take matters here into his own hands.
