And Clarrissa Kinnison, tense and strained, waited in her room for the instant of her husband's death. They two were one, with a oneness no other man and woman had ever known. If one died, from any cause whatever, the other would feel it.

She waited. Five minutes—ten—fifteen—half an hour—an hour. She began to relax. Her fists unclenched, her shallow breathing grew deeper.

Two hours. Kim was still alive! A wave of happy, buoyant relief swept through her; her eyes flashed and sparkled. If they hadn't been able to kill him in two hours, they never could. Her Kim had plenty of jets.

Even the top minds of Boskonia could not kill her Kim!

XXVIII.

The Arisians and the Children of the Lens had known that Eddore must be attacked as soon as possible after the fall of Ploor. They were fairly certain that the interspatial use of planets as projectiles was new; but they were completely certain that the Eddorians would be able to deduce in a short time the principles and the concepts, the fundamental equations, and the essential operators involved in the process. They would find nth space or one like it in one day; certainly not more than two. Their slaves would duplicate the weapon in approximately three weeks. Shortly thereafter both Ultra Prime and Prime Base, both Klovia and Tellus, would be blown out of the ether. So would Arisia—perhaps Arisia would go first. The Eddorians would probably not be able to aim such planets as accurately as the Arisians had, but they would keep on trying and they would learn fast.

This weapon was the sheer ultimate in destructiveness. No defense against it was possible. There was no theory which applied to it or which could be stretched to cover it. Even the Arisian Masters of Mathematics had not as yet been able to invent symbologies and techniques to handle the quantities and magnitudes involved when those interloping masses of foreign matter struck normal space.

Thus Kit did not have to follow up his announced intention of making the Arisians hurry up. They did not hurry, of course, but they did not lose or waste a minute. Each Arisian, from the youngest guardian up to the oldest philosopher, tuned a part of his mind to Mentor, another part to some one of the millions of Lensmen upon his list, and flashed a message.

"Lensman, attend—keep your mind sensitized to this, the pattern of Mentor of Arisia, who will speak to you as soon as all have been alerted."

That message went throughout the First Galaxy, throughout intergalactic space, and throughout what part of the Second Galaxy had felt the touch of Civilization. It went to Alsakan and Vandemar and Klovia, to Thrale and Tellus and Rigel IV, to Mars and Velantia and Palain VII, to Medon and Venus and Centralia. It went to flitters, battleships, and loose planets. It went to asteroids and moonlets, to planets large and small. It went to newly graduated Lensmen and to Lensmen long since retired; to Lensmen at work and at play. It went to every living wearer of the First-Stage Lens of the Galactic Patrol.
