on. We simply
haven't got a thing to go on."

"No chance at all?" asked Chambers.

Craven shook his head slowly.

"At least you could try," snapped Grant.

"Now, wait," Chambers snapped back. "You seem to forget Dr. Craven is
one of the best scientists in the world today. I'm relying on him."

Craven smiled. "I can't do anything with what Page and Manning have, but
I might try something of my own."

"By all means do so," urged Chambers. He turned to Grant. "I observed
you have carried out the plans we laid. Martian Irrigation hit a new low
today."

Grant grinned. "It was easy. Just a hint here and there to the right
people."

Chambers looked down at his hands, slowly closing into fists. "We have
to stop them some way, any way at all. Keep up the rumors. We'll make
it impossible for Greg Manning to finance this new invention. We'll take
away every last dollar he has."

He glared at the publicity man. "You understand?"

"Yes, sir," said Grant, "I understand perfectly."

"All right," said Chambers. "And your job, Craven, is to either develop
what Page has found or find something we can use in competition."

Craven growled angrily. "What happens if your damn rumors can't ruin

"In that case," said Chambers, "there are other ways."

"Other ways?"

Chambers suddenly smiled at them. "I have a notion to call Stutsman back
to Earth."

Craven drummed his fingers idly on the arm of his chair. "Yes, I guess
you do have other ways," he said.

Greg's hand snapped the switch and the screen suddenly was blank as the
televisor set returned instantly to the laboratory.

"That explains a lot of things," he said. "Among them what has happened
to my stocks."

Russ sat in his chair, numbed. "That little weak-kneed, ratting traitor,
Wilson. He'd sell his mother for a new ten-dollar bill."

"We know," said Greg, "and Chambers doesn't know we know. We'll follow
every move he makes. We'll know every one of his plans."

Pacing up and down the room, he was already planning their campaign.

"There are still a few things to do," he added. "A few possibilities we
may have overlooked."

"But will we have time?" asked Russ.

"I think so. Chambers is going to go slow. The gamble is too big to risk
any slip. He doesn't want to get in bad with the law. There won't be any
strong-arm stuff ... not un
