"Just started," said Russ.

Greg straightened and glanced down the row of television machines. Some of them were dead, their switches closed, but on the screens of many of the others was the same effect as on this machine. Their operators were working frustratedly at the controls, trying to focus the image, bring it into sharp relief.

"Can't seem to get a thing, sir," said one of the men. "I was working on the fueling station out on Io, and the screen just went haywire."

"Mine seems to be all right," said another man. "I've had it on Sandebar for the last couple of hours and there's nothing wrong."

A swift check revealed one fact. The machines, when trained on the Jovian worlds, refused to function. Anywhere else in space, however, they worked perfectly.

Russ stoked and lit his pipe, snapped off his machine and swung around in the operator's chair.

"Somebody's playing hell with us out around Jupiter," he stated calmly.

"I've been expecting something like this," said Greg. "I have been afraid of this ever since Craven blanketed us out of the Interplanetary building."


"He really must have something this time," Russ agreed. "He's blanketing out the entire Jovian system. There's a space field of low intensity surrounding all of Jupiter, enclosing all the moons. He keeps shifting the intensity so that, even though we can force our way through his field, the irregular variations make it impossible to line up anything. It works, in principle, just as effectively as if we couldn't get through at all."
