At Stahl's words now, Steel realized he was standing there alone. Most of the men who had surrounded him had left to go for Stahl. Most of these were now lying in black heaps on the floor. The rest stood among the charred bodies, staring helplessly as Stahl's guards advanced across the room, ready for the slightest excuse to use their rifles again. The terrible silence of their advance was broken only when Lois Harmon sobbed, buried her golden head in her father's arms. * * * * * Steel stood there alone, realizing just how much alone he was. He'd thrown a wrench into the Harmon gang's plans, for which they'd been in the act of doing away with him. Then his rescuers--whom he'd called here himself--had turned out to be an equal menace, bringing the same fate that they'd saved him from. He'd jumped out of The Bear's frying pan into the shortly forthcoming fire of Stahl's volt rifles.... "When I received your message and learned who The Bear was," the fat man smiled, halting before Steel, "I preferred not to bother the police with what was really a private matter between Dr. Harmon and myself." "Private matter!" Dr. Harmon's cold eyes were frightening behind his spectacles. One hand soothed his daughter's head but the other was knotted, white-knuckled at his side. "Yes, you always did look upon my experiments as a private matter. You didn't care whether they benefited mankind or not--if they interfered with your vita-lamp profits, you tried to crush them." "And crush them I shall," Stahl replied easily, turning to the old man. "When we sighted the coordinate location Mr. Steel so kindly sent us, we blasted the whole area immediately. We blasted the entrance to your hideout before your men had time to use any trick weapons you've developed." Which had been the end of Dirk and the men who'd been up there with him, Steel thought. "At this moment," Stahl continued, waving toward the door through which he'd entered, "others of my guards are searing every room in the place. When we leave here there won't be the slightest sign that this place ever existed. The world will continue to think Dr. Harmon died fifteen years ago." The guards herded the remaining few of Dr. Harmon's men into a corner. "Now," the fat man told Dr. Harmon, "if you'll kindly lead us on a little tour of your power plant here, you'll have exactly that much longer to live." The old man hesitated a moment. Then he lifted his white head, took his daughter's hand and moved slowly ahead past the generator houses. One of the guards shoved Steel after them and the procession started down the long room. "On the way here," Stahl said chattily to the old man and the girl, "we received a telenews report that a freight liner had just discovered something rather startling in the Venusian space sector. Earth scientists are in a dither." He laughed. "The planet Venus seems to have disappeared...."
