"He must know our limitations," Dr. O'Connor said at last. "He must be
perfectly well aware that there's not a single thing we can _do_ about
him. He must know that we can neither find nor stop him. Why should he
worry? He can afford to ignore us--or even bait us. We're helpless, and
he knows it."

That, Malone thought, was about the most cheerless thought he had heard
in some time.

"You mentioned that you had an insulated room," the FBI agent said
after a while. "Couldn't you let your men think in there?"

Dr. O'Connor sighed. "The room is shielded against magnetic fields and
electromagnetic radiation. It is perfectly transparent to psionic
phenomena, just as it is to gravitational fields."

"Oh," Malone said. He realized rapidly that his question had been a
little silly to begin with, since the insulated room had been the place
where all the tests had been conducted in the first place. "I don't want
to take up too much of your time, doctor," he said after a pause, "but
there are a couple of other questions."

"Go right ahead," Dr. O'Connor said. "I'm sure I'll be able to help
you."

Malone thought of mentioning how little help the doctor had been to
date, but decided against it. Why antagonize a perfectly good scientist
without any reason? Instead, he selected his first question, and asked
it. "Have you got any idea how we might lay our hands on another
telepath? Preferably one that's not an imbecile, of course."

Dr. O Connor's expression changed from patient wisdom to irritation. "I
wish we could, Mr. Malone. I wish we could. We certainly need one here
to help us with our work--and I'm sure that _your_ work is important,
too. But I'm afraid we have no ideas at all about finding another
telepath. Finding little Charlie was purely fortuitous--purely, Mr.
Malone, fortuitous."

"Ah," Malone said. "Sure. Of course." He thought rapidly and discovered
that he couldn't come up with one more question. As a matter of fact,
he'd asked a couple of questions already, and he could barely remember
the answers. "Well," he said, "I guess that's about it, then, doctor. If
you come across anything else, be sure and let me know."

He leaned across the desk, extending a hand. "And thanks for your time,"
he added.

Dr. O'Connor stood up and shook his hand. "No trouble, I assure you," he
said. "And I'll certainly give you all the information I can."

Malone turned and walked out. Surprisingly, he discovered that his feet
