Jeff cursed in his teeth. How could he tell? He had no evidence that Conroe carried any extra-sensory power whatsoever, and surely there was little enough to indicate that he had any more than most latent powers. There were so many, many possibilities, and so little concrete evidence to go on.

And if Conroe had such powers, why had he been so startled to meet Jeff on the stairs? Why the look of fear and disbelief that had streaked across his face? Jeff glanced at his watch, saw the minute hand move to eleven-thirty. He would have to hurry, for the guards would be down the escalator in a few moments. And these thoughts of his could lead to nowhere. Conroe had been jolted to see Jeff. It must have been a horrible shock for him to realize that the Hunter had followed him, even into this death trap, to know that the Hunter would have the outside so well guarded that he, the Hunted, could never get out. Now Conroe would be forced to gamble against being caught and assigned to work as a Mercy Man. Yes, it must have been a horrible jolt for Conroe, driving one last, searing bolt of fear into his already desperate mind. And what would he have tried to do?

A thousand ideas flooded Jeff's mind. He was waiting for testing. Perhaps Conroe, somehow, had been tested already? Could Jeff succeed in stalling Schiml, especially if the rumors spinning down the dark corridors were true? There was no sure way of telling. All Jeff could do was to search the file rooms Blackie had directed him to.

He stopped at the entrance to the escalator, pored over the floor plan Blackie had sketched for him. He spotted the escalator, oriented himself on the plan. The filing rooms were two flights below. If he could reach them without being stopped.... He moved silently onto the down shaft, his eyes moving constantly for a sight of a gray-garbed prowler.

At the foot of the escalator he stopped short. Three men in white were pushing a gurney along the corridor. Jeff glanced quickly at the twitching form under the blankets. Then he looked away hurriedly. One of the men dropped behind and waved at him sharply as he stepped off the stairs. The man still wore the operating mask hanging from his neck, and his hair was tightly enclosed in the green-knit operating cap.

The doctor tipped a thumb over his shoulder and pointed down the corridor. "You coming to fix the pump?"

Jeff blinked rapidly. "That's right," he croaked. "Did—did Jerry come with the tools yet?"

"Nobody came in yet. We just finished. Been in there since three this afternoon, and the damned pump went kerflooey right in the middle. Had to aspirate the poor joe by hand, and if you think that's not a job—" The doctor wiped sweat from his forehead. "Better get it fixed tonight. We've got another one going in at eight in the morning and we've got to have the pump."

Jeff nodded, and started down the hall, his heart thudding madly against his ribs. He reached the open door to one of the operating rooms. Slipping quickly into the small dressing-room annex, he snatched one of the gowns and caps from the wall.

If they were still operating this late, it was a heaven-sent chance. No guard would bother him if he were wearing the white of a doctor or the green of a surgeon. He struggled into the clumsy gowning, tying it quickly behind his back, and slipped the cap over his head. Finally he found a mask, snapped it up under his ears as he had seen it worn by the doctors in the corridors.
