But Trent held grimly to the leash, running as fast as his numbed body would go.

And he knew he could not go much further. That soon he would drop to the ground in exhaustion. That his last reserve of energy was nearly spent.

And then his eyes peered through the darkness ahead and he saw a glow of lights in the distance. And suddenly he knew those lights. And he became aware of where they were racing toward.

It was the Rocket Proving Grounds!

And the fence of the government project loomed close ahead.

And as they neared the fence, Trent's eyes pierced the darkness and he saw a jagged tear in the metal mesh of the fence. A tear that stood as high as a man, a hole through which a man could have entered.

The Great Dane bounded toward that hole and Trent followed the dog through it. He felt the animal pause momentarily and he nearly stumbled over a body lying on the ground at his feet just inside the fence.

His heart stood still for a moment and the girl's name sped to his lips. But he never uttered the word. For he suddenly saw that it was the body of a guard. A body whose torn throat lay red and gory in death.

And then the Great Dane let a howl of anger out on the night wind, and the beast leaped forward again, Trent running behind it.

And ahead of them, Trent saw a great looming shape in the darkness, and as his eyes fell upon it, a despairing terror gripped him.
