now." They moved down the corridor. Only one guard lay in their path but he was down on his haunches, asleep. They glided past him, Maxis' gun held ready. They moved on until they were approaching a more brightly lighted intersection. A small table was located against the bars of a corner cell and a Martian sat at the table occupied with some papers. The trio approached from behind the man quietly. He heard them when they were a few steps away. He turned. Maxis took a last bold step and was towering over the seated one. Maxis spoke casually, but with authority. "I've been sent to deliver Fanton to the council hall." Maxis did not expect cooperation from the guard. But he hoped for something else.

He will be suspicious and completely confounded, but he will bring you here. In the meantime I can better stave off trouble with the authority this post gives me." Maxis looked at Helen and
