He glanced back up and frowned in sudden surprise. What the-?

His left hand groped in a locker, feeling for his powerful binoculars, but he never lowered his eyes from the brilliant streaks tracing fiery paths through the night. They seemed to be descending, but that wasn't all they were doing-not by a long chalk! They looked almost like shooting stars, but he'd never heard of meteors that changed trajectory in mid-course!

He jammed the binoculars to his eyes, adjusting to Amanda's movement with practiced ease as he held the flaming lines in his field of vision. It was no help; whatever they were, they were far too distant to make out details, even with the glasses. In fact, they must be at one hell of an altitude for him to see them at all at this range!

They seemed to be heading roughly in his direction, but they were dropping rapidly towards the southern horizon. Whatever they were, they looked like they'd impact long before-

He froze as a spark suddenly separated from one whatever-they-were and streaked away, dancing crazily. Damn it, that had to be a controlled flight path! No free-falling object would pursue such an insane course. It was almost as if the thing were taking evasive action!

The thought popped into his mind and lodged there as one of the other light streaks arced impossibly back towards the fleeing spark. He watched intently, then winced-even at this distance-at the suddenly redoubled brilliance as the dot which had spawned the spark hurled a pair of fiery darts at the pursuing one ... just before still more brilliant specks lanced out from the pursuer, heading for the spark!

He blinked rapidly, compensating for the painful intensity of those flashes. In 1973, Lieutenant (j.g.) Dick Aston had found himself in the Sinai, attached to the Israeli army as an observer, and he'd never forgotten the morning he'd watched a massed Israeli-Egyptian dogfight. He remembered the smoke trails of the missiles, the suddenness and silence with which they'd appeared so high above, the white wakes of contrails and the plunging black and red fireballs of broken aircraft. He remembered well ... and somehow he knew he was seeing an insane echo of that long ago madness.

It was ridiculous. Even if there'd been the least reason to expect hostilities out here in mid-ocean, nobody had fighters that could do what those flaming lines of light were doing. He knew it-but he also knew it was happening, and he held his breath as the darts of fire flashed silently through the night sky, then gasped as two dots of light flared intolerably bright and perished.

The remaining lights raced even lower. He sensed their incredible speed, even if distance did make them seem to move with trancelike slowness. They swept towards the horizon, bunching and weaving, dancing as if for advantage, and he watched in wonder as they finally disappeared below the curvature of the earth.

He lowered the glasses, suddenly aware of the tension which had gripped him as that tension eased, and grinned wryly, castigating himself for his overactive imagination. Dogfighting lights! UFOs, no doubt! He wondered if they were Arcturians or Boskonians-or Ming the Merciless and Flash Gordon? Undoubtedly there was some entirely rational explanation... .

And then the southern horizon lit with a glaring spall of light that wrenched him to his feet. The brilliant glare burned away the night, reflecting on water that was suddenly a glassy mirror even at this range. He'd seen more than his share of explosions, but never one like that!

He averted his eyes instinctively, refusing to look directly at the boiling pinprick, but he couldn't have turned his attention elsewhere to save his life. He breathed quickly, shallow with tension, waiting for ... something. He had no idea what, but surely there would-

He gasped in disbelief as yet another burst of light blazed up. This one was lower, he thought, below the horizon-he was seeing its reflection on the distant cloud base, not the light itself. But what in God's name could it be?

He was still wondering when he saw the light streaks again. But this time there were only three of them, shooting up into the heavens like a trio of rockets-no, wait! There was a fourth, racing after the first three! Yet another burst of flame splashed the heavens, and he watched one of the leaders vanish. The other three were still coming, charging towards him in a madly climbing spiral. There! Another dart of fire, chasing the leading dot, and more from the last light chasing the second! What in God's na-?

Some instinct screamed warning, and he flung up his hands, shielding his eyes just before actinic fury smashed the dark. He cried out in horror, cowering down, and his brain gibbered. It was a nuclear explosion! That was the only thing it could be, and thank God in Heaven it was so high! Even here he could feel its radiant heat, and he paled as he considered the tides of radiation racing out from its heart. At least the wind was out of the northwest! Whatever fallout that terrible explosion had spawned would be carried-

His thoughts broke off yet again as scarcely less titanic explosions erupted. They blazed in terrible succession, pursuing the first light dot across the vault of heaven, and they were gaining. His brain worked mechanically, overloaded with confusion and shock. Those warring dots were sweeping higher and higher-they had to be clear up at the outer edge of the stratosphere! Nothing ever built could do that-yet something was doing it. And still more fireballs shredded the night!

The leading light dot swerved, as if that last explosion had come too close, and arced crazily up in what an aircraft would have called a half loop-but what did whatever that was call it? He had no idea, but he watched helplessly, unable to look away, as the vengeful pursuer closed on its victim. Blue lightning flickered, stabbing his eyes almost as painfully as the exploding nukes had done, and suddenly the wounded dot was falling.

He watched it begin its plunge and knew it had been killed. It plummeted uncontrollably towards the sea, and he felt a sudden stab of stark terror. It was falling towards him! What if its enemy decided to finish it off with yet another nuke?

But there was nothing he could do if it happened, and he rejected a panicky urge to throw himself flat on the deck. He watched the dot fall, and the second one followed it for several seconds before it suddenly broke away, streaking off to the southwest.

He heaved a deep breath of relief as the immediate threat of immolation vanished, but the stricken light still plunged downward. God, but it must have been a hell of a long way up! It was still heading roughly towards him, and he swallowed as its size registered. The thing was getting bigger and bigger, shedding bits and pieces of itself. Thunder rumbled, pounding him like a bellow of God's wrath, and he realized it was the sound of the explosions. He wished he'd thought to do a flash-bang count to get some idea of range, but he hadn't.

It was still coming! He told himself the ocean was a huge target, that it would never hit Amanda whatever it looked like, but the disintegrating object seemed to be plunging straight into his eyes. He knew it was an illusion, but he felt his muscles tightening once more.

A flood of adrenaline snapped him out of his shock. It might not hit him, but that thing had to be huge! Who knew what kind of splash it was going to throw up when it hit? He leapt to the wheel, tripping over the tether of the safety line he always wore on deck. He disengaged the self-steering, checking the wind direction by instinct, and swung Amanda's bow slightly to starboard. He wanted whatever the hell it was to impact bows on to him, just in case.

He was staring up at the plunging object, his heart in his mouth, when it exploded before his eyes. Dripping bits of brilliance erupted outward, and a bright-blue star seemed to leap from the wreckage. His abused eyes cringed to the fresh explosion, but he felt a stab of relief. Whatever it was had broken up. The falling bits and pieces were burning out before they hit.
