"The whole system is too hot for us right now,” observed Sual Av. “You should have heard the audio news bulletins going back and forth while you were sleeping. Three Planeteers try to kidnap Earth Chairman! Notorious outlaws foiled in daring attempt.’ The system's ringing with it!"
"It'll ring with the news if we're gunned out of space by those cruisers converging on us,” grunted Gunner Welk sourly. “Do you think we can slip through them, John?"
"I think so,” Thorn clipped. “We've got to keep straight on. Turkoon, the asteroid that's the pirates’ main base, lies in the part of the Zone almost directly ahead."
Thorn stared with narrowed eyes through the broad window, into the magnificent star-flecked vault.
The little ship of the Planeteers was roaring out through the void at top speed, millions of miles outside the orbit of Mars. The bright, small disk of the sun was dead astern, its rays hiding the gray blob of Earth, away from which they had been fleeing for so many long hours.
Ahead of them, the void was thick with bright stars. Brilliant among them gleamed the big yellow topaz of Saturn, and beyond, and to the left, the fainter green sparks of Uranus and Neptune. Pluto was somewhere farther away, off to the right. And Erebus, their mysterious, ultimate goal, lay invisible still farther off — the dark, enigmatic outpost of the solar system.
Directly ahead of the racing little ship, only a few million miles away, extended a wide band of countless tiny specks of light, stretching parallel with the equator of the system. That broad band of light-specks was the Zone, the great asteroidal belt whirling between the orbits of Mars and Jupiter.
Thorn gazed tautly into the Zone. That mighty wilderness of countless planetoids and meteor-swarms, which all ordinary shipping avoided by running above or below, was the No Man's Land of the Solar System. In it the space pirates had long had their lairs, from which they still sallied forth to levy ton on the interplanetary shipping. Countless naval expeditions had tried to clean the place out, and had been baffled by the shifting swarms of meteors and tiny planets which made it impossible to conduct organized operations in there without prohibitive losses.
John Thorn's brown hands clenched. In there, in the Zone, at the pirates’ asteroid base, was the girl who alone in the system, held the secret of mysterious Erebus, the secret that would make possible the securing of the precious radite from that far, dark planet. Somehow, that girl's secret must be secured.
"Calling flagship Gull!” suddenly boomed a deep voice from the audio speaker. “Cruiser Tharine, reporting. Our aura shows the Planeteers’ ship four hundred thousand miles from us, eighteen degrees counter-sunwise."
