Marino nodded. He was small and wiry, with catlike movements and exceedingly bright eyes under his jet black eyebrows. "We'd be wise to get on over while we talk," he said. Faircloth nodded and stepped into the little tube-car that was waiting at the end of the platform. It was a tight fit for two men, and Paul ducked by reflex as it gave a lurch and dipped down the chute into a narrow tunnel, hanging free and speeding ahead on its electronic guide beam. "Is the Condor Building where he was spotted?" Marino nodded. "In Center City, Chicago. First thirty-six floors are commercial, and the twenty above are residential. He's pinned pretty definitely on the forty-second, in a large residential suite. No idea why he chose it or how long he's been there--" He turned apologetic eyes to Faircloth. "I'm Psi-High--I guess you know. We've got him located and triangulated, and we can keep him pretty well pinned if he doesn't try to give us a shower. We're pretty sure he knows we're there." "Shower?" Marino nodded, grimly tapping his forehead. "A barrage, the works. This Alien's got a powerful psi. And I mean powerful. He gave it to one of our Psi-High men yesterday. It was savage. Nearly ripped him apart." Faircloth shivered. "But you can keep track of him." "Yes." Marino lit a cigarette with nervous fingers. "Roberts put Psi-Highs out to spot him, but he doesn't want any Psi-Highs in on the kill." His voice was flat with disappointment. "Political pressure, I guess. People couldn't bear to give a Psi-High credit for anything--" He glanced at Faircloth and reddened. "Sorry. No offense. It just slipped out." He bit his lip. "Anyway, that's what you're here for. Half a dozen other psi-negatives will help you. I hope God'll be helping you too." Faircloth grinned tightly. "Got you nervous?" "It's got me plenty nervous." Faircloth nodded again, rubbing a hand across his eyes. "All right. I want your best men, every one of them, to go in with me. I don't care whether they're Psi-High or not. Neither does Roberts; he's with you folks all the way. But we've got to get this creature and get him cold. He's slick. Is the building sewed up?" "Tight as a vacutainer." "Good. Keep it under cover, and try to keep the Psi-Highs from broadcasting any more than necessary." Marino gave him a queer look. "They'll do their best, of course." "Right." Faircloth ran a hand through his brown hair and loosened his tie a trifle. "As soon as the building is cleared from rush hour, I want the power shut off all over the building. Elevators, lights, everything. We'll be on the 41st floor, and a squad will be on the 43rd. We'll close in together." Marino shook his head. "I hope it works. They had him just as tight in Des Moines last week, and he slid right through." The man's eyes were worried. "We just don't know what we're fighting. That's the whole trouble. Even the Psi-Highs are up a tree." * * * * *
