"Next," Malone said, "we have to do a little supposing. This project must be handled by a fairly large group, since no individual can do it alone. This large group has to be telepathic—and not only for the reasons Dr. O'Connor and I specified."

"And why else?" Sir Kenneth demanded.

"They've also got to know exactly when to make this victim of theirs change his mind," Malone said. "Right?"

"Correct," Sir Kenneth said.

"We've got to look for a widespread organization of telepaths," Malone said, "with enough mental discipline to hold onto a tough mental shield. Strong, trained, sane men."

"A difficult assignment," Sir Kenneth commented.

"Well," Malone said, "suppose you hold on for a second—don't go away—and let me figure something out."

"I shall wait," sir Kenneth said, "without."

"Without what?" Malone murmured. But there was no time for games. Now, then, he told himself—and sneezed.

He shook his head, cursed softly and went on.
