Meanwhile, the police prepared to close in on the mountain cabin. Equipped with gas bombs, machine pistols and recoiless rifles, they came struggling through a snow clogged pass and down the mountain sides from hovering planes. Unseen in the darkness, they crept through the woods toward the house. A rifle shot cracked as a guard sighted them with his sniperscope. One of the policemen fell, a bullet in his leg. The lights in the house went out, and gun flashes lanced through the windows. Bullets, hunting their prey like angry wasps, snarled through the darkness. Roger was locked in an upstairs bedroom with a guard before the door. During the next two hours, the roar of machine pistols and the crack of rifle fire split the mountain stillness and echoed from the hillsides. At the end of that time, the police withdrew to rearrange their strategy. Juarez sat on the floor near a broken window and cleaned his machine pistol. "I think that it is time to kill Lorin and get out of here," he said, as he placed a fresh clip in the magazine. "It will serve us to good advantage." "Fool!" Gomez exclaimed. "If they found us with a dead man on our hands, we wouldn't stand a chance. I have used this place enough to know that they have us pinned in. We can use Lorin as a bargaining point. We will arrange to take him with us and drop him by parachute. But--the parachute will not open. A convertiplane, which I have called, will meet us above the clouds and take us away before they can stop us." "They will not trust our word," Juarez said. "We cannot get away with it." "Oh, but we can," Gomez said. "The police know that Lorin's death would have regrettable results. Even the fact that he is a citizen of the North American Union would be enough to start trouble, let alone his position as a key research man on the neutron project. They will do anything to see that he remains alive. The scheme will further enrage the North Americans and might perhaps incite them to war." "I see," replied Juarez. "An excellent plan. Let's contact the police, and see what happens." * * * * * Unseen by the guards around the house, four policemen crawled through the snow. Wearing white uniforms, they blended so well with their background that even the sniperscope men didn't see them. Their view was limited by the fact that most of the large lights that had flooded the area with infra red radiation had been shattered by gunfire. Individual beams were insufficient to sweep the whole area. Carrying thirty-shot rocket launchers and rocket powered gas bombs, they took positions around the house and aimed the slender guns. At a radio signal, streams of red fire shot from the tubes, and the small rockets tore through every window in the house. In a few minutes, the place was saturated with sleep gas. Not a man moved throughout the building. Policemen in gas masks converged on the house.
