I was only inactive a moment. I had thought Anita would have on her helmet. But she was reluctant, or confused. "Gregg." "We've got to get out of here! Up through the overhead locks to the dome." "Yes--" She fumbled with the helmet. Under the floor-grid the climbing men on the ladder were audible. They were already nearing the top. The trap door was closed: Anita and I were crouching on it. There was a thick metal bar set in a depressed groove of the grid. I slid it in place--it would seal the trap for a time, at any rate. A degree of confidence came to me. We had a few moments before there could be any hand-to-hand conflict. That giant electronic projector would eventually be used against Grantline: it was the brigands' most powerful weapon. Its controls were here--by Heaven, I would smash them! That at least I could do! I jumped for the window. Miko's signals had stopped, but I caught a glimpse of his distant moving curve-lights. A flash came up at me, as in the window I became visible to the brigands on the ship's deck. It was a small hand-projector, hastily fired, for it went wide of the window. It was followed by a rain of small beams, but I was warned and I dropped my head beneath the high sill. The rays flashed diagonally upward through the oval opening, hissed against our vaulted roof. The air snapped and tingled with a shower of blue-red sparks, and the acrid odor of the released gases settled down upon me. * * * * * The trajectory controls of the projector were beside me. I seized them, ripped and tore at them. There was a roar down on the deck. The projector had exploded. A man's agonized scream split the confusion of sounds. It silenced the brigands on the deck. Under our floor-grid those on the ladder had been pounding at the trap-door. They stopped, evidently to see what had happened. The bombardment of our windows ceased momentarily. I cautiously peered out the window again. In the wreck of the projector three men were lying. One of them was screaming horribly. The dome-side was damaged. Potan and other men were frantically investigating to see if the ship's air were hissing out. A triumph swept me. They had not found me so meek and inoffensive as they might have thought! Anita clutched at me. She still had not donned her helmet. "Put it on!" "But Gregg--" "Put it on!" "I--I don't want to put it on until you put yours on." "I've smashed the projector! We've stopped them coming up for a while." But they were still on the ladder under our floor. They heard our voices; they began thumping again. Then pounding. They seemed now to have some heavy implement. They rammed with it against the trap. But the floor seemed holding. The square of metal grid trembled, yielded a little. But it was good for a few minutes longer.
