"Nothing," Quay said quickly. "Absolutely nothing. Bolen wants actual tests badly, and the Institute wouldn't do it. Snap your fingers, and give him a hundred and fifty people to work on, and it's yours to use for nothing. He'll do the installing, and he _wants_ to keep it secret. It's essential, he says, to get an accurate reaction from the subjects affected. For him it's perfect, because we're running a continuous efficiency check, and if this thing does the job like it's supposed to do it, we'll have gained the entire benefits for nothing. How can we lose?" Cutter stared at Quay for a moment, his mind working swiftly. "Call Horner in on this, but nobody else. Absolutely nobody else. Tell Horner to write up a contract for this fellow to sign. Get a clause in there to the effect that this fellow, Bolen, assumes all responsibility for any effects not designated in the defining part of the contract. Fix it up so that he's entirely liable, then get it signed, and let's see what happens." Quay smiled fully and stood up. "Right, sir." He had done a good job, he knew. This was the sort of thing that would keep him solidly entrenched in Cutter's favor. "Right, George," he said, remembering that he didn't need to call Cutter sir anymore, but he knew he wouldn't hear any more from Cutter, because Cutter was already looking over a blueprint, eyes thin and careful, mind completely adjusted to a new problem. * * * * * Edward Bolen called the saucer-sized disk, the Confidet. He was a thin, short, smiling man with fine brown hair which looked as though it had just been ruffled by a high wind, and he moved, Cutter noticed, with quick, but certain motions. The installing was done two nights after Cutter's lawyer, Horner, had written up the contract and gotten it signed by Bolen. Only Quay, Bolen, and Cutter were present. Bolen fitted the disks into the base of the plastic chair cushions, and he explained, as he inserted one, then another: "The energy is inside each one, you see. The life of it is indefinite, and the amount of energy used is proportionate to the demand created." "What the hell do you mean by energy?" Cutter demanded, watching the small man work. Bolen laughed contentedly, and Quay flushed with embarrassment over anyone laughing at a question out of Cutter's lips. But Cutter did not react, only looked at Bolen, as though he could see somehow, beneath that smallness and quietness, a certain strength. Quay had seen that look on Cutter's face before, and it meant simply that Cutter would wait, analyzing expertly in the meantime, until he found his advantage. Quay wondered, if this gadget worked, how long Bolen would own the rights to it. Cutter drove the Cadillac into Hallery Boulevard, as though the automobile were an English Austin, and just beyond the boundaries of the city, cut off into the hills, sliding into the night and the relative darkness of the exclusive, sparsely populated Green Oaks section.
