Flier after flier went tailspinning to horrible death while his comrades fled in all directions. It was soon over. The greater number of the Mercutians were twisted smoldering wrecks. The few who escaped were rapidly diminishing dots in the cold starlight. Its work finished, the rescuing space flier settled softly to the ground, in the midst of the embattled cheering Earthmen, temporarily gone insane. The air-lock port yawned, and a slim figure darted out, straight into Hilary's outstretched arms. "Joan!" * * * * * Behind her danced a small red-haired individual, his homely features grinning with delight. Under his arm swung heavily a submachine gun. He disappeared almost immediately into the vast bearlike grip of his gigantic friend. His shrill voice went on unceasingly, but strangely muffled, as Grim hugged him. Finally he extricated himself, ruffled, breathless, but still talking. "What did I tell you, you big ox?" he shrilled. "We'll chase them off the Earth, sweep 'em out into space." "Why, you little gamecock," the giant observed affectionately, "I'm beginning to believe you can do it." "We thought you had gone for good," said Hilary, holding Joan tightly to him as if he feared to lose her again. "What happened to you on the Robbins Building?" "Can't get rid of us that easily, can he, Joan?" The little man smirked knowingly at the girl. "It was all very simple," he went on. "No sooner had you two left us than we heard the thud of a flier landing on the other end of the roof. The pilot looked out at us startled. We recognized each other simultaneously. It was our old friend--Urga." Hilary clenched his fist. He had a good many scores to settle with the Cor. Wat saw his action. "I did my best," he stated apologetically. "I ran for the machine gun. But by that time Urga had shot aloft again. Didn't seem as though he wanted to wait. I heard his whistle shrilling in the air. Fliers came thick as flies." He spread his hands in a quaint gesture. "What could I do, Hilary?" his voice was appealing. "Any minute I expected to have a ray on us. I couldn't wait for you two, the _Vagabond_ would have been a little pile of ashes. Besides, there was Joan. She kicked and struggled: she wanted to stay for you, but I shoved her in the ship, locked the port, and went scooting up like a rocket. You should have seen the Mercutians scatter." * * * * * For the first time in his life words seemed to fail him. "You--are--not--angry?" he fumbled, looking for all the world like a bedraggled dog who knows he has been in mischief. "Angry?" Hilary fairly whooped. "What for? For saving the ship, Joan, all of us? Why, you little bit of pure gameness, you did the only sensible thing." Wat grinned from ear to ear. "But why," Grim interrupted, "didn't you have sense enough to come back here, instead of scaring everybody to death?"
