White. But there was a compressed fury in his voice. Manning sighed. "All right." Dugan crawled like a weasel. Manning lost sight of him. He waited with humming nerves, firing spaced shots into the enemy's log fortress. Then he noticed he had stopped drawing any return fire. That might mean things had started happening inside the house, if it wasn't a trick—He discarded most of his caution and darted into the open, zigzagging from scanty cover to cover—something must have happened inside—and flattened against the rustic wall beside one shattered window, just in time to hear a voice beyond it exclaim hoarsely, "Gut!" That was all he wanted to know. If anything was going gut in there, it was time Ray Manning got into the picture. He cleared the window-ledge with automatic level. There was a big, raftered room, and in the middle of the floor Eddie Dugan was struggling groggily to get up, while behind him stood a white-goateed civilian with a wrench, and in front of him a tough-looking younger man was lifting a rifle. The two Germans saw the gun in Manning's hands and made a tableau as they were. It was broken as the burly one's grip relaxed and his Mauser clattered on the floor. Manning motioned toward the goatee. "Dr. Kahl? Better drop that," he advised in German. The little physicist looked down at his wrench and let it fall with an expression of disgust. Then he glared at Manning and called him a couple of names culled from biology rather than physics. "If your man hadn't caught Wolfgang reloading—As it is, you have interrupted my work at the most crucial point imaginable—a work that might yet save the Reich—" He woke up to the nature of his audience, and finished lamely, "And which is in any case the greatest scientific advance of all time." Dugan got shakily back to his feet, scooped up his dropped Browning, and trained it on Wolfgang. "Is that Kahl?" he inquired sourly. "If I'd known this guy wasn't the one we had to capture, I'd have let him have it when I first got the drop on him." Manning didn't answer. His eyes roved rapidly about the interior, alert against another surprise entrance; but anybody else on the premises was lying pretty low. One, in fact, was doing it just under the window Manning had first fired at. He was no longer a factor.
