gone. I've made you rich and your children too. If you'd rather go to jail than work yourself to death staying out, it's no business of mine!" He opened his car-door and stepped inside. But Bud Gregory jumped up and shambled anxiously after him. "But, Mr. Murfree!" he protested. "Look heah! My gawsh, Mr. Murfree! You cain't do that to me! Uh—uh—if you want some kinda dinkuses, o'course I'll try to make 'em, suh. But don't go off and leave me with all that trouble, suh! Please!" CHAPTER III Ruthless Enemies Either the crews of the space-ships were aliens to humanity with no knowledge of mankind, or else they were men and conducting a ruthless war of nerves and an exhaustive test of the ability of the world outside their nation to defend itself. Four days after the seizure of a transatlantic plane, four coaches of the Trans-Siberian Railroad went skyward, accompanied by a tumultuous mass of roadbed and other debris. Two days later a building in the Georgetown section of Washington, D.C., went screaming heavenward in a shapeless mass of collapsed timbers.
