"No," Weldon said. "The rogue may have considered that unnecessary. After all, he'd made his point again. Sending the best of our tame telepaths after him was like setting spaniels on a tiger. Ordinarily, he could reach a telepath's mind only within his own range, like that of any other person. But if they were obliging enough to make contact with him, they would be instantly at his mercy, wherever he might be. We took the hint; the attempt wasn't repeated. Our other telepaths have remained in the seclusion of security islands, and so far the rogue has showed no interest in getting at them there."
Weldon stubbed his cigarette out carefully in the ashtray beside him, added, "You see now, I think, why we feel it is necessary to take extreme precautions in the further handling of your diex projector."
There was silence for some seconds. Then Dr. Lowry said, "Yes, that much has become obvious." He paused, pursing his lips doubtfully, his eyes absent. "All right," he went on. "This has been rather disturbing information, Ferris. But let's look at the thing now.
"We've found that diex energy can be employed to augment the effects of the class of processes commonly referred to as telepathic. The projector operates on that theory. By using it, ordinary mortals like Arlene and myself can duplicate some of the results reportedly achieved by the best-trained telepaths. However, we are restricted in several ways by our personal limitations. We need the location devices to direct the supporting energy to the points of the globe where the experiments are to be carried out. And so far we have not been able to 'read the mind'—to use that very general term—of anyone with whom we are not at least casually acquainted."
Weldon nodded. "I'm aware of that."
"Very well," Lowry said. "The other advantage of the projector over unaided natural telepathy is its dependability. It works as well today as it did yesterday or last week. Until a natural telepath actually has been tested on these instruments, we can't be certain that the diex field will be equally useful to him. But let's assume that it is and that he employs the projector to locate the rogue. It should be very easy for him to do that. But won't that simply—in your phrasing—put him at the rogue's mercy again?"
Weldon hesitated, said, "We think not, Ben. A specialist in these matters could tell you in a good deal more detail about the functional organization in the mind of a natural telepath. But essentially they all retain unconscious safeguards and resistances which limit their telepathic ability but serve to protect them against negative effects. The difference between them and ourselves on that point appears to be mainly one of degree."
Lowry said, "I think I see. The theory is that such protective processes would be correspondingly strengthened by employing the diex field...."
"That's it," Weldon said. "To carry the analogue I was using a little farther, we might again be sending a spaniel against a tiger. But the spaniel—backed up by the projector—would now be approximately tiger size ... and tiger-strong. We must assume that the rogue would be far more skilled and deadly in an actual mental struggle, but there should be no struggle. Our telepath's business would be simply to locate his man, identify him, and break away again. During the very few seconds required for that, the diex field should permit him to hold off the rogue's assault."
