"No trouble at all," Dirk said from the screen. "Having trouble with this headache of mine though." He grinned faintly through his bandages. "Second one that guy's given me today. I must be slipping." "Well, come on in and have a drink," the short-haired one said. "Looks like you did a good job on Venus anyhow." Steel was so bewildered he completely forgot that video worked both ways. If he could see Dirk, Dirk could see him. This didn't occur to him till Dirk's grin faded abruptly and he squinted into the room's darkness from the screen. "Hey!" Dirk yelled. "Who's that behind you--!" Then, as the two heads before Steel twisted around, "Look out! It's Steel! He's loose again!" Steel went into action. His fist drove into the face nearest him--the short-haired one's. He knocked him over into the video with a punch that would have knocked out a horse. His left hand caught the other man's collar. His fist started in again. But this was a blow that never landed. * * * * * Steel's arm froze in mid-swing. He stared at the face above the collar he was holding as if he'd caught a ghost. He had. He was staring into the bespectacled eyes of a man who was supposed to have been dead fifteen long years--Hampton Stahl's dead partner, Lois Harmon's dead father--_Dr. Albert Harmon_.... Steel stood there holding Dr. Harmon's collar, fist poised, for a long crazy moment. The skull cap had fallen off, revealing the scientist's shaggy white hair. From his lined face, his gray eyes looked up at Steel, troubled but without fear. "Well?" he said, as if the next move were entirely up to Steel. His voice was remarkably clear for a man of his age. "Dr. Harmon...." Steel turned him loose and lowered his hand. "Maybe you'd better explain a few things, Doctor," he said shakily. Instead of explaining, however, the old man shot a hand toward the video table--toward an alarm button. Steel saw it just in time. He caught the hand and shoved the old man back into his chair. Then he scooped the volt gun from the other man's holster. "Dr. Harmon," he said, "finding you here when you're supposed to have been dead fifteen years explains a lot about this place. The police are going to be mighty interested." Moving around where he could keep his eye on the door as well as on the old man, he reached out and switched the video into the Earth frequency band. Dirk's face had already disappeared. "The police'll be here in about one hour," Steel said. He twirled a dial to the frequency he'd arranged with Stahl's listener at the Vita-Heat Building. It was hard to believe that a man who had been so well loved as Dr. Harmon could have traded his reputation for a criminal career--but here he was. Obviously, he'd faked his own death and hidden here ever since--another brilliant mind that had followed pure science too far.
