"Monsters!" that thin voice had cried in a tone that was vibrant with terror. What could it be?--great ships out of space?--an invasion? Or beasts?... But Harkness' vision failed him there. He knew only that a fast ship was moored just outside. He had planned vaguely to seize it; he had needed it for his own escape; but he needed it a thousand times more desperately now. Chet might have been delayed, and he must warn him.... The thoughts were flashing like hot sparks through his brain as he leaped. * * * * * He bore the heavier body of Schwartzmann to the floor. He rained smashing blows upon him with a furious frenzy that would not be curbed. The weapon with its deadly detonite bullet came toward him. In the same burst of fury he tore the weapon from the hand that held it; then sprang to his feet to stand wild-eyed and panting is he aimed the pistol at the cursing man and dragged him to his feet. "The ship!" he said between heavy breaths, "--the ship! Take me to it! You will tell anyone we meet it is all right. One word of alarm, one wrong look, and I'll blow you to hell and make a break for it!" The pistol under Harkness' silken jacket was pressed firmly into Schwartzmann's side; it brought them safely past excited guards and out into the storm; it held steady until the men had fought their way through blasts of rain to the side of the anchored ship. Not till then did Schwartzmann speak. "Wait," he said. "Are you crazy, Harkness? You can never take off; the trees are close; a straight ascent is needed. And the wind--!" He struggled in the other's grasp as Harkness swung open the cabin door, his fear of what seemed a certain death overmastering his fear of the weapon. He was shouting for help as Harkness threw him roughly aside and leaped into the ship. Outside Harkness saw running figures as he threw on the motors. A pistol's flash came sharply through the storm and dark. A window in the chateau flashed into brilliance to frame the figure of a girl. Tall and slender, she leaned forward with outstretched arms. She seemed calling to him. * * * * * Harkness seized the controls, and knew as he did so that Schwartzmann was right: he could never lift the ship in straight ascent. Before her whirling fans could raise her they would be crashed among the trees. But there were two helicopters--dual lift, one forward and one aft. And Walt Harkness, pilot of the second class, earned immediate disbarment or a much higher rating as he coolly fingered the controls. He cut the motor on the big fan at the stern, threw the forward one on full and set the blades for maximum lift, then released the hold-down grips that moored her.
