"Can you help us, doctor?" he asked.

Craven shrugged. "Perhaps," he said acidly. "If I could only be left to my work undisturbed, instead of being dragged into these stupid conferences, I might be able to do something."

"You already have, haven't you?" asked Chambers.

"Very little. I've been able to blank out the televisor that Manning and Page are using, but that is all."

"Do you have any idea where Manning and Page are?"

"How could I know?" Craven asked. "Somewhere in space."

"They're at the bottom of this," snarled Stutsman. "Their damned tricks and propaganda."

"We know they're at the bottom of it," said Craven. "That's no news to us. If it weren't for them, we wouldn't have this trouble now, despite your bungling. But that doesn't help us any. With this new discovery of mine I have shielded this building from their observation. They can't spy on us any more. But that's as far as I've got."

"They televised the secret meeting of the emergency council when it met in Satellite City on Ganymede the other day," said Chambers. "The whole Jovian confederacy watched and listened to that meeting, heard our secret war plans, for fully ten minutes before the trick was discovered. Couldn't we use your shield to prevent such a situation again?"

"Better still," suggested Stutsman, "let's shield the whole satellite. Without Manning's ghostly leaders, this revolt would collapse of its own weight."
