As Earth's faster-than-light spaceship hung in the void between galaxies, Arcot, Wade, Morey and Fuller could see below them, like a vast shining horizon, the mass of stars that formed their own island universe. Morey worked a moment with his slide rule, then said, "We made good time! Twenty-nine light years in ten seconds! Yet you had it on at only half power...."

Arcot pushed the control lever all the way to full power. The ship filled with the strain of flowing energy, and sparks snapped in the air of the control room as they raced at an inconceivable speed through the darkness of intergalactic space.

But suddenly, far off to their left and far to their right, they saw two shining ships paralleling their course! They held grimly to the course of the Earth ship, bracketing it like an official guard.

The Earth scientists stared at them in wonder. "Lord," muttered Morey, "where can they have come from?"

John W. Campbell first started writing in 1930 when his first short story, When the Atoms Failed, was accepted by a science-fiction magazine. At that time he was twenty years old and still a student at college. As the title of the story indicates, he was even at that time occupied with the significance of atomic energy and nuclear physics.

For the next seven years, Campbell, bolstered by a scientific background that ran from childhood experiments, to study at Duke University and the Massachusetts Institute of Technology, wrote and sold science-fiction, achieving for himself an enviable reputation in the field.

In 1937 he became the editor of Astounding Stories magazine and applied himself at once to the task of bettering the magazine and the field of s-f writing in general. His influence on science-fiction since then has been great. Today he still remains as the editor of that magazine's evolved and redesigned successor, Analog.

PROLOGUE

In the early part of the Twenty Second Century, Dr. Richard Arcot, hailed as "the greatest living physicist", and Robert Morey, his brilliant mathematical assistant, discovered the so-called "molecular motion drive", which utilized the random energy of heat to produce useful motion.

John Fuller, designing engineer, helped the two men to build a ship which used the drive in order to have a weapon to seek out and capture the mysterious Air Pirate whose robberies were ruining Transcontinental Airways.

The Pirate, Wade, was a brilliant but neurotic chemist who had discovered, among other things, the secret of invisibility. Cured of his instability by modern psychomedical techniques, he was hired by Arcot to help build an interplanetary vessel to go to Venus.

The Venusians proved to be a humanoid
