The only trouble was that Earth couldn't counterattack. Their ships were still out-classed by those of the Rats. And the Rats, their racial pride badly stung, were determined to wipe out Man, to erase the stain on their honor wherever Man could be found. Somehow, some way, they must destroy Earth.

And now, Al Pendray thought bitterly, they would do it.


The Shane had sneaked in past Rat patrols to pick up a spy on one of the outlying Rat planets, a man who'd spent five years playing the part of a Rat slave, trying to get information on their activities there. And he had had one vital bit of knowledge. He'd found it and held on to it for over three years, until the time came for the rendezvous.

The rendezvous had almost come too late. The Rats had developed a device that could make a star temporarily unstable, and they were ready to use it on Sol.

The Shane had managed to get off-planet with the spy, but they'd been spotted in spite of the detector nullifiers that Earth had developed. They'd been jumped by Rat cruisers and blasted by the superior Rat weapons. The lifeboats had been picked out of space, one by one, as the crew tried to get away.

In a way, Alfred Pendray was lucky. He'd been in the sick bay with a sprained ankle when the Rats hit, sitting in the X-ray room. The shot that had knocked out the port engine had knocked him unconscious, but the shielded walls of the X-ray room had saved him from the blast of radiation that had cut down the crew in the rear of the ship. He'd come to in time to see the Rat cruisers cut up the lifeboats before they could get well away from the ship. They'd taken a couple of parting shots at the dead hulk, and then left it to drift in space—and leaving one man alive.

In the small section near the rear of the ship, there were still compartments that were airtight. At least, Pendray decided, there was enough air to keep him alive for a while. If only he could get a little power into the ship, he could get the rear air purifiers to working.

He left the lifeboat and closed the door behind him. There was no point in worrying about a boat he couldn't use.

He made his way back toward the engine room. Maybe there was something salvageable there. Swimming through the corridors was becoming easier with practice; his Cadet training was coming back to him.
