"They're going to board us," Tom said.

Johnny nodded, his eyes suddenly bright. "I think you're right. And if they do, we may have a chance. But we've got to split up.... Greg, you take the control cabin here, try to keep them out if you can. Tom can cover the main corridor to the storage holds, and I'll take the engine room section. That will sew up the entrances to control, here, and give us a chance to stop them."

"They may have a dozen men," Tom said. "They could just shoot us down."

"I don't think so," Johnny said. "They want us, not the ship, or they wouldn't bother to board us. We may not be able to hold them off, but we can try."

"What about making a run for it in the Scavenger?" Greg said.

Johnny chuckled grimly. "It'd be a mighty short run. That Ranger's got homing shells that could blow the Scavenger to splinters if we tried it. Our best bet is to put up such a brawl that they think twice about taking us."

They parted in the corridor outside control, Johnny heading down for the engine room corridors, while Tom ran up toward the main outer-shell corridor, a Markheim stunner in his hand. The entire outer shell of the ship was storage space, each compartment separately sealed and connected with the two main corridors that circled the ship. On each side these corridors came together to join the short entry corridors from the scout-ship airlocks.

Tom knew that the only way the ship could be boarded was through those locks; a man stationed at the place where the main corridors joined could block any entry from the locks ... as long as he could hold his position. Tom reached the junction of the corridors, and crouched close to the wall. By peering around the corner, he had a good view of the airlock corridor.

Tom gripped the Markheim tightly, and he dialed it down to a narrow beam. Nobody had ever been killed by a stunner ... but a direct hit with a narrow beam could paralyze a man for three days.

There was movement at the far end of the airlock corridor. A helmeted head peered around the turn in the corridor; then two men in pressure suits moved into view, walking cautiously, weapons in hand. Tom shrank back against the wall, certain they had not seen him. He waited until they were almost to the junction with the main corridor; then he took aim and pressed the trigger stud on his Markheim. There was an ugly ripping sound as the gun jerked in his hand. The two men dropped as though they had been pole-axed.
