Up on the summit of the crater the two small figures were still fighting. All this turmoil had taken no more than a minute or two.
A lurking Martian outside? The brigand, Miko? More than ever, Grantline was determined to get out. He shouted to his men to don some of the other suits, and called for some of the hand projectors.
But he could not get out through these main admission ports. He could have forced the panels open perhaps; but with the pressure changing mechanism broken, it would merely let the air out of the corridor. A rush of air, probably uncontrollable. How serious the damage was, no one could tell as yet. It would perhaps take hours to repair it.
Grantline was shouting, "Get those weapons! That's a Martian outside! The brigand leader, probably! Get into your suits, anyone who wants to go with me! We'll go by the manual emergency exit."
But the prowling Martian had found it! Within a minute Grantline was there. It was a smaller two-lock gateway of manual control, so that the person going out could operate it himself. It was in a corridor at the other end of the main building. But Grantline was too late! The lever would not open the panels!
Had someone gone out this way and broken the mechanisms after him? A traitor in the camp? Or had someone come in from outside? Or had the skulking Martian outside broken this lock as he had broken the other?
The questions surged on Grantline. His men crowded around him. The news spread. The camp was a prison! No one could get out!
And outside, the skulking Martian had disappeared. But Wilks and Haljan were still fighting. Grantline could see the two figures up on the observatory platform. They bounded apart, then together again. Crazily swaying, bouncing, striking the rail.
They went together in a great leap off the platform onto the rocks, and rolled in a bright patch of Earthlight. First one on top, then the other.
They rolled unheeding to the brink. Here, beyond the midway ledge which held the camp, it was a sheer drop of a thousand feet, on down to the crater floor.
