ny more help
to us."

"You told him to go back and see if he couldn't find something else,
didn't you?" asked Grant.

"Yes, I did," Chambers told him. "But apparently he couldn't find it."

"I tried," pleaded Wilson. Perspiration stood out on his forehead. The
cigarette in his mouth was limp and dead. "One of them was always there.
I never could get hold of any papers. I asked questions, but they were
too busy to answer. And I couldn't ask too much, because then they would
have suspected me."

"No, you couldn't do that," commented Craven with an open sneer.

In the laboratory Russ pounded the arm of his chair with a clenched
fist. "The rat sold us out!"

Greg said nothing, but his face was stony and his eyes were
crystal-hard.

On the screen Chambers was speaking to Wilson. "Do you think you could
find something out if you went back again?"

Wilson squirmed in his chair.

"I'd rather not." His voice sounded like a whimper. "I'm afraid they
suspect me now. I'm afraid of what they'd do if they found out."

"That's his conscience," breathed Russ in the laboratory. "I never
suspected him."

"He's right about one thing, though," Greg said. "He'd better not come

Chambers was talking again: "You realize, of course, that you haven't
been much help to us. You have only warned us that another kind of power

Wilson bristled, like a cowardly animal backed into a corner. "I told
you what was going on. You can be ready for it now. I can't help it if I
couldn't find out how all them things worked."

"Look here," said Chambers. "I made a bargain with you and I keep my
bargains. I told you I would pay you twenty thousand dollars for the
information you gave me when you first came to see me. I told you I'd
pay you for any further additional information you might give. Also I
promised you a job with the company."

Watching the financier, Wilson licked his lips. "That's right," he said.

Chambers reached out and pulled a checkbook toward him, lifted a pen
from its holder. "I'm paying you the twenty thousand for the warning.
I'm not paying you a dime more, because you gave me no other
information."

Wilson leaped to his feet, started to protest.

"Sit down," said Chambers coldly.

"But the job! You said you'd give me a job!"

Chambers shook his
