electronically, readied for flight with their stolen planet to unknowable distances of deep space. The men and women waited, their breath emerging in brief white frosty spurts in the cold air. And nothing happened. After twenty minutes, Trace put a trembling hand to his forehead. "We lose," he said. He saw Slough begin to walk away from them, going back along the gradual slope among the bare trees, but he did not even call after him. It didn't matter a damn now, what or who the midget was. "We lose," he said again, and hugged Jane fiercely. And then the sky exploded. CHAPTER XV Trace flung himself on the ground, sheltering Jane; he felt rather than saw that Bill had done the same with Barbara. He gazed up, and saw the great rack of clouds torn and dispersed by the force of the blast. There was a chain of brilliant green-white balls of light, like so many bursting sky-rockets, that stretched from horizon to black horizon across his world. He thought of the shards of metal, the evil whistling splinters and hunks of meteoring death that would rain out of the sky after such a multiple explosion, and he buried his face in Jane's soft hair, trying desperately to cover her whole body with his own.

The Irish intuition, second sight, or what-have-you it works in a cockeyed way, he said to himself, waiting for the shower of molten hail. Slough was of the extraterrestrials too! Oh, not the Graken, the wicked green one-eyed bird-footed destroyers. But he was a saucerman, right enough. Lord knew how many of them had been living among us before the greenies attacked. No telling how many had died, how many still lived. Trace remembered the saucer sightings that had perplexed the Air Force for so many years before. The blue-lit disks that soared and dipped and shot away from pursuit, the disks which had been seen by reputable folk for—well, possibly for centuries. Funny he hadn't thought of it before, but all those well-vouched-for sightings could not have been Graken. The Graken shot into our system no longer ago than late December! And all the long while before we'd been under the surveillance of blue-lit saucers—not green, but blue at night
