"Well," said Midguard, when he finally sat down, "now that Mr. Oak is here, I suggest we begin scheduling our program."

There was a momentary silence, then the boyish Brentwood said, "I think we ought to explain to Mr. Oak just what our problem is."

That was generally agreed on, and for the next half hour I heard another re-run of information I already had. I just tried to look receptive and kept my mouth shut.

"... So you see," Midguard finally wound up, "in order to put McGuire through his paces, your co-operation is vitally necessary."

"The first thing to do," rumbled the barrel-chested Videnski, "is to run a verbal check on him, to see how the brain is functioning."

"His circuits should be checked, too," said Brentwood softly. "But that can be done later. I'll get my testing equipment ready, so that I can hook it in immediately after you get through with the verbal check." He looked over at Miss Deveraux. "Vivian?"

"I thought perhaps it might be quicker if we ran a few straight math checks on him before the verbal check," she said. "It wouldn't take long, and if there's anything wrong in that area, we'll know what to look for in the later checks. Would that be all right with you, Ted?"

Videnski nodded. "Certainly, certainly. Save us some backtracking, maybe."

Nobody asked me anything. I was just a tool; I was the switch that would turn on the machine these people wanted to play with, that was all. I could see a long, boring day ahead for Daniel Oak.
