"May I compliment you on your attitude, Dr. Brill. Such an interest can shorten your period of orientation, and it raises my already considerable expectations for you. But we do not pretend to any originality of technique."

After watching the attendant run through twenty-five cards with Nina, Lucifer was quite ready to agree with Huth. The technique was crude, far below minimal laboratory standards.

Nina's attention wandered about the room, but she called off the cards without hesitation. The attendant took her through three runs, checked his file record and stood up with a shrug. He said something to Huth in a language that blurred and rasped.

"Dr. Brill," said Huth, "will you oblige us now?"

Lucifer stepped resolutely to the desk, but the palms of his hands were moist. Over the past two decades he had taken many tests, enough to know that he could never score above chance save for an occasional run of coincidence.

And this was not one of those runs. He saw it in the attendant's manner before five cards had been turned. Desperately, he fumbled ahead, guessing blindly.

At the end of the first run, the attendant spoke rapidly to Huth.

Lucifer saw Nina watching him with surprise.

"This technique is incredible!" he snapped at Huth. "With all the distractions in this room, not to mention the emotional stress of our situation, a true score would have to depend on chance!"

"That is not necessarily so," Huth answered calmly. "The stronger a psi sense may be, the more easily it is brought into use, regardless of external circumstances. You Earth scientists go to incredible lengths to test under laboratory conditions an ability that does not belong in the laboratory."
