"What was it?" the shaken girl asked. "I think that I remember your saying 'Vee-Two gas.' That's forbidden! Anyway, I owe you my life, Conway, and I'll never forget it--never. Thanks--but the others--how about all the rest of us?" "It was Vee-Two, and it is forbidden," Costigan replied grimly, eyes fast upon the flashing plate, whose point of projection was now deep in the bowels of the vessel. "The penalty for using it or having it is death on sight. Gangsters and pirates use it, since they have nothing to lose, being on the death list already. As for your life, I haven't saved it yet--you may wish I'd let it ride before we get done. The others are too far gone for oxygen--couldn't have brought even you around a few seconds later, quick as I got to you. But there's a sure antidote--we all carry it in a lock-box in our armor--and we all know how to use it, because crooks all use Vee-Two and so we're always expecting it. But since the air will be pure again in half an hour we'll be able to revive the others easily enough if we can get by with whatever is going to happen next. There's the bird that did it, right in the air-room! It's the chief engineer's suit, but that isn't Franklin that's in it. Some passenger--disguised--slugged the chief--took his suit and projectors--hole in duct--p-s-s-t! All washed out!

"His armor is so much better than that emergency suit you are wearing, and he's got Mr. Franklin's Lewiston, besides!" "Don't be an idiot!" he snapped. "We can't have a live pirate aboard--we're going to be altogether too busy with outsiders directly. Don't worry, I'm not going to give him a break. I'm taking a Standish and I'll rub him out like a blot. Stay right here until I come back after you," he commanded, and the heavy, vacuum insulated door of the lifeboat clanged shut behind him as he leaped out into the promenade. Straight across the saloon he made his way, paying no attention to the inert forms scattered here and there. Going up to a blank wall, he manipulated an almost invisible dial set flush with its surface, swung a heavy door aside, and lifted out the Standish--a fearsome weapon. Squat, huge, and heavy, it resembled somewhat an overgrown machine rifle, but one possessing a thick, short telescope, with several opaque condensing lenses and parabolic reflectors. Laboring under the weight of the thing, he strode along corridors and clambered heavily down short stairways. Finally he came to the
