Finally he said, "This mind picking—it's absolutely necessary?"
"Absolutely. We must know where that serum is hidden."
Lanson sighed heavily. "I'll authorize it," he said. He looked beaten.
Washington to New York was a matter of some few minutes. The precious authorization in his hands, Walton spoke to di Cassio via the screener setup at Security Keep, informed him of what was going to be done with him. Then, despite the fat man's hysterical protests, he turned the authorization over to Martinez with instructions to proceed with the mind pick.
It took fifty-eight minutes. Walton waited in a bare, austere office somewhere in the Keep while the mind-picking technicians peeled away the cortex of di Cassio's mind. By now Walton was past all ambivalence, all self-doubt. He thought of himself as a mere robot fulfilling a preset pattern of action.
At 1950 Martinez presented himself before Walton. The little security head looked bleak.
"It's done. Di Cassio's been reduced to blubber and bone. I wouldn't want to watch another mind picking too soon."
"You may have to," Walton said. "If di Cassio wasn't the right one, I intend to go straight down the line on all hundred-odd of them. One of them dealt with Fred. One of them must know where the Lamarre papers are."
Martinez shook his head wearily. "No. There won't need to be any more mind-picking. We got it all out of di Cassio. The transcript ought to be along any moment."
As the security man spoke, an arrival bin in the office flashed and a packet arrived. Walton broke impatiently for the bin, but Martinez waved him away. "This is my domain, Mr. Walton. Please be patient."
