tock quotations to Callisto. With that advance knowledge of what the
board is doing in New York, we can make back every dime I've lost. We
can take Mr. Chambers to the cleaners!"

Russ grinned. "Exactly," he said. "We'll know 45 minutes in advance of
the other traders what the market will be. Let's see Chambers beat
that."

_CHAPTER SEVEN_

Ben Wrail was taking things easy. Stretched out in his chair, with his
cigar lit and burning satisfactorily, he listened to a radio program
broadcast from Earth.

Through the window beside him, he could look out of his skyscraper
apartment over the domed city of Ranthoor. Looming in the sky, slightly
distorted by the heavy quartz of the distant dome, was massive Jupiter,
a scarlet ball tinged with orange and yellow. Overwhelmingly luminous,
monstrously large, it filled a large portion of the visible sky, a sight
that brought millions of tourists to the Jovian moons each year, a sight
that even the old-timers still must stare at, drawn by some unfathomable
fascination.

Ben Wrail stared at it now, puffing at his cigar, listening to the
radio. An awe-inspiring thing, a looming planet that seemed almost ready
to topple and crash upon this airless, frigid world.

Wrail was an old-timer. For thirty years--Earth years--he had made his
home in Ranthoor. He had seen the city grow from a dinky little mining
camp enclosed by a small dome to one that boasted half a million
population. The dome that now covered the city was the fourth one. Four
times, like the nautilus, the city had outgrown its shell, until today
it was the greatest domed city in the Solar System. Where life had once
been cheap and where the scum of the system had held rendezvous, he had
seen Ranthoor grow into a city of dignity, capital of the Jovian
confederacy.

He had helped build that confederacy, had been elected a member of the
constitution commission, had helped create the government and for over a
decade had helped to make its laws.

But now ... Ben Wrail spat angrily and stuffed the cigar back in his
mouth again, taking a fresh and fearsome grip. Now everything had
changed. The Jovian worlds today were held in bond by Spencer Chambers.
The government was in the hands of his henchmen. Duly elected, of
course, but in an election held under the unspoken threat that
Interplanetary Power would withdraw, leaving the moons circling the
great planet without heat, air, energy. For the worlds of the Jovian
