There were a dozen officers standing in front of the big lighted screen and when we crossed the room to join them without announcing our arrival—well, that made fourteen.

I can't even explain how I got the idea there was a chill in the air that seemed to wrap itself around me in moist, clinging folds, because no section of the sky ship was more comfortably heated.

I didn't spend more than a minute or two trying to puzzle it out, because the "furious sick shapes of nightmare," to quote from a poem I wasn't sure I'd ever read, only disturb you when you give them more encouragement than they're entitled to.

The only really important thing was that we could see him in bent light on the big screen—a tiny, spacesuited figure climbing along the airframe, laden down with something cumbersome that he kept pushing before him in a completely weightless way as he inched further and further toward the rocket's stern.

All at once, I knew what was going to happen to him. I was as sure of it as I am that I have two big toes that point a little inward and that Joan sometimes tenderly jokes about.

Between Earth and Mars space isn't empty. It hasn't been empty for more than half a century, which is a pretty good record on the survival scale for man-made, mechanical implants. The early Sputniks didn't last one-tenth as long.

I knew without waiting for Commander Littlefield to finish what he was saying to one of the officers and issue a command that the needle frequencies scattered throughout the void on all sides of us were the only composite weapon we could count on to save the sky ship and all the people between its decks who didn't want to be vaporized. And that took in practically everyone on board.

Sure, I know. Everyone had thought that the millions of filament-thin wires which had been put into orbit around Earth in the seventh and eighth decades of the twentieth century and later into orbit around Mars and far out into interstellar space would only be used for purposes of communication. Project Needles, or, if you want to be strictly technical, Project West Ford.

God grant that they may some day be used in no other way. But when a man climbs out on the airframe of a sky ship, for the sole purpose of blowing it up——

There is only one way I can do justice to the speed with which it happened and the awful, mind-numbing finality of it. It is not something which should be recorded in a paragraph, a page, but in two sentences at most.
