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...

CHAPTER 1 On the morning the radar reported something odd out in space, Lockley awoke at about twenty minutes to eight. That was usual. He'd slept in a sleeping bag on a mountain-flank with other mountains all around. That was not unprecedented. He was there to make a base line measurement for a detailed map of the Boulder Lake National Park, whose facilities were now being built. Measuring a base... 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...

Detective Sergeant Fitzgerald found a package before his door that morning, along with the milk. He took it inside and opened it. It was a remarkably fine meerschaum pipe, such as the sergeant had longed irrationally to own for many years. There was no message with it, nor any card. He swore bitterly. On his way to Headquarters he stopped in at the orphanage where he usually left such gifts. On other... more...

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...

CHAPTER IThe Tube The generator rumbled and roared, building up to its maximum speed. The whole laboratory quivered from its vibration. The dynamo hummed and whined and the night silence outside seemed to make the noises within more deafening. Tommy Reames ran his eyes again over the power-leads to the monstrous, misshapen coils. Professor Denham bent over one of them, straightened, and nodded. Tommy... more...
