he hurried to an antigrav shaft and floated up to the floor on which
Tortha Karf's office was.

Tortha Karf was asleep in his chair; Dalla was eating a dinner that
had been brought in to her--something better than the sandwich and mug
of coffee Vall had mentioned to Thalvan Dras. Several of the bureau
chiefs who had been there when he had gone out had left, and the
psychist who had taken charge of the prisoner was there.

"I think he's coming out of the drug, now," he reported. "Still
asleep, though. We want him to waken naturally before we start on him.
They'll call me as soon as he shows signs of stirring."

"The Opposition's claiming, now, that we drugged and hypnotized
Salgath into making that visiscreen confession," Dalla said. "Can you
think of any way you could do that without making the subject
incapable of lying?"

"Pseudo-memories," the psychist said. "It would take about three times
as long as the time between Salgath Trod's departure from his
apartment and the time of the telecast, though--"

"You know much higher math?" Vall asked the psychist.

"Well, enough to handle my job. Neuron-synapse inter-relations,
memory-and-association patterns, that kind of thing, all have to be
expressed mathematically."
