They were broadcasts from nowhere—sinister emanations flooding in from space—smashing any receiver that picked them up. What defense could Earth devise against science such as this?   Did the broadcasts foretell flesh-rending supersonic blasts? The first broadcast came in 1972, while Mahon-modified machines were still strictly classified, and the world had heard only rumors about them. The first... more...

The sky was black, with myriads of stars. The ground was white. But it was not really ground at all, it was ice that covered everything—twenty miles north to the Barrier, and southward to the Pole itself, past towering mountains and howling emptiness and cold beyond imagining. The base was almost buried in snow. Off to one side of the main building a faint yellowish glow was the plastic dome of the... more...

Bordman knew there was something wrong when the throbbing, acutely uncomfortable vibration of rocket blasts shook the ship. Rockets were strictly emergency devices, these days, so when they were used there was obviously an emergency. He sat still. He had been reading, in the passenger lounge of the Warlock—a very small lounge indeed—but as a senior Colonial Survey officer he was well-traveled... more...

PART I "... The profound influence of civilian morale upon the course of modern war is nowhere more clearly shown than in the case of that monstrous war-engine popularly known as a 'Wabbly.' It landed in New Jersey Aug. 16, 1942, and threw the whole Eastern Coast into a frenzy. In six hours the population of three States was in a panic. Industry was paralyzed. The military effect was... more...

1 The little Med Ship came out of overdrive and the stars were strange and the Milky Way seemed unfamiliar. Which, of course, was because the Milky Way and the local Cepheid marker-stars were seen from an unaccustomed angle and a not-yet-commonplace pattern of varying magnitudes. But Calhoun grunted in satisfaction. There was a banded sun off to port, which was good. A breakout at no more than sixty... more...

Nobody ever saw the message-torp. It wasn't to be expected. It came in on a course that extended backward to somewhere near the Rift—where there used to be Huks—and for a very, very long way it had traveled as only message-torps do travel. It hopped half a light-year in overdrive, and came back to normality long enough for its photocells to inspect the star-filled universe all about. Then it... more...

I. The whole thing started when the clock on the Metropolitan Tower began to run backward. It was not a graceful proceeding. The hands had been moving onward in their customary deliberate fashion, slowly and thoughtfully, but suddenly the people in the offices near the clock's face heard an ominous creaking and groaning. There was a slight, hardly discernible shiver through the tower, and then... more...

It started in Greece on the day after tomorrow. Before the last act raced to a close, Coburn was buried to his ears in assorted adventures, including a revolution and an invasion from outer space! We're not given to throwing around the word "epic" lightly, but here is one! Swashbuckling action, a great many vivid characters, and a weird mystery—all spun for you by one of the master... more...
