time. They would have to be several hundred, if not thousand, kilometers clear of the impact zone before they were safe. Even then, they would have to land and find some sort of shelter. Caliban had no desire to pilot an aircar while a massive supersonic shockwave was tearing through the sky. Anything in the air that was not torn apart would undoubtedly lose control and crash. So how to

"Sweet burning stars!" Beddle cried out. Caliban looked at him, and saw that he was looking straight up, into the early night sky.

Caliban looked up as well-and found himself torn between absolute wonder and utter terror. There it was, directly overhead: the first, the largest fragment, a fat dot of light growing visibly larger even as he watched. And there, behind it, like beads on a string, haloed in a faint nimbus of dust, the other fragments, trailing off like beads on a string toward the north. There was a flash of light, and Caliban could see the farthest-off fragment break into two as another set of splitting charges went off.

Time was not short. Time was gone. And there was no way to escape before those wondrous terrors in the sky came down.

But wait a moment. Prospero. Prospero had to have been planning to cut it nearly this close. He would have stayed until the last possible moment, in order to gloat over his victim, and to make certain that Beddle had no chance at all to escape.

Prospero's aircar. He would have flown in on something that would give him a chance to escape. "Come on," he said to Beddle, and grabbed him, none too gently, by the collar.

He hurried Beddle along and practically threw him into Prospero's aircar. It was a small, trim, two-seater job. Caliban sat down at the pilot's controls-and suddenly understood how Prospero had planned to get away. This aircar was capable of reaching orbit.

"Strap yourself in," Caliban said as he powered up the craft.

Beddle fumbled with the straps, and had to try two or three times before he managed to get the buckles to hook up. perhaps it was the first time Beddle had ever put on his own seatbelt. "Ready," the human said nervously.

Caliban made no reply. He brought the aircar up to hover power, taxied it out from under the camouflaged roof of the hangar, and kept moving forward until they were over the lake itself, the hover effect throwing up a shimmering mist of water that enveloped the car. Caliban lifted the car just enough higher so as to get above the hover mist, and look about at the landscape that was about to die. In a few minutes, all of this would be erased for all time. He and Simcor Beddle would be the last beings ever to look upon it.

Caliban lingered a moment longer, and moved the throttle forward, pointing the nose of the aircar up and to the east.

The east, thought Caliban as he guided the aircar toward the hope of safety. East. Home of the dawn, and new beginnings. He wondered if he would live long enough to see another sunrise.

"ALL FRAGMENTS ON course," Unit Dum announced. "All fragments are descending well within their intended parameters. The operation is proceeding according to plan. Impact of the first fragment in five minutes, twenty-two seconds."

Fredda Leving felt her heart pounding, her mouth going dry. They were going to do it. They were actually going to do it. This mad idea had moved from improbable theory to undeniable fact. They were about to drop a comet on their own world. She found herself amazed by the boldness, the courage, the desperate willingness to try something-anything-in order to save the planet. It was not the sort of action the universe expected out of the Spacers. It was not the sort of thing Spacers would ever do.

And it suddenly occurred to Fredda that perhaps they were not Spacers anymore. The world of Inferno was about to change beyond recognition. Perhaps the people of that world were going to change as well.

And that thought inspired a most un-Spacerlike reaction in Fredda. Spacers were supposed to be cautious, conservative, and frightened of change. But the thought of change did not scare Fredda. It excited her. She was impatient for it. She glanced at the countdown clock and decided she wanted the next five minutes and ten seconds to pass as quickly as possible.

She couldn't wait for the future to get there.
