Momentum of the ship didn't cease when the rockets stopped, of course. They were still moving, but not very fast and not in the direction they wanted to go. Gingerly Docchi tried out the magneslippers; he was clumsy, but no longer helpless in the gravityless ship. He stared futilely at the instruments as if he could wring more secrets than the panel had electronic access to.

"It's mechanical trouble of some sort," he said uneasily. "There's one way of finding out."

Before he could move, Anti was in the corridor that led away from the control compartment.

"Stay here, Anti," he said. "I'll see what's wrong."

She reached nearly from the floor to the ceiling. She missed by scant inches the sides of the passageway. Locomotion was easy enough for her; turning around wasn't. Anti didn't turn.

"Look, honey," her voice floated back. "You brought me along for the ride. That's fine, but I'm not satisfied with it. I want to earn my fare. You stay and run the ship because you know how and I don't. I'll find out what's wrong."

"But you won't know what to do, Anti." There was no answer. "All right," he said in defeat. "Both of us ought to go. Jordan, you stay at the controls."

Anti led the way because Docchi couldn't get around her. Determinedly he shuffled along. There was a trick to magneslippers that he had nearly forgotten. Slowly it was coming back to him—shuffle instead of striding.

It was a dingy, poorly lighted passageway in an older ship. Handicap Haven definitely didn't rate the best equipment that was produced. On one side was the hull of the ship; on the other, a few small cabins. None were occupied. Anti stopped. The passageway ended in a cross corridor that led to the other side of the ship.

"We'd better check the stern rocket tubes," he said, still unable to see around her. "Open it up and we'll take a look."

"I can't," said Anti. "There are handles, but the thing won't open. There's a red light, too. Does that mean anything?"

His heart sank. "It does. Don't try to open it. With your strength, you might be unlucky enough to do it."

"That's a man for you," said Anti sharply. "First he wants me to open it, and then he tells me not to."

"There's a vacuum in there. The combustion cap has been retracted. That's the only thing that will actuate the warning signal. You'd die in a few seconds if you somehow managed to open the lock to the rocket compartment."

"What are we waiting for? Let's get busy and fix it."

"Sure, fix it. You see, Anti, that didn't happen by itself. Someone, or something, was responsible."

"Who?"

"Did you see anyone when we were loading your tank in the ship?"

"Nothing. I heard Cameron shouting, a lot of noise. All I could see was what was directly overhead. What does that have to do with it?"

"I think it has to do with a geepee. I thought they all dropped outside. Maybe there was one that didn't."

"Why a geepee?" she asked blankly.

"In the first place, no man is strong enough to move the combustion cap. But if he should somehow manage to exert super-human effort, as soon as the cap cleared the tubes, rocket action would cease. The air in the compartment would exhaust into space and anyone in there would die."

"So we have a dead geepee in there."

"A geepee doesn't die. Not even become inactive; it doesn't need air." Docchi tried to think the thing through. "Not only that, a geepee might be able to escape from the compartment. The lock would close as soon as the pressure dropped. But a geepee...."

Anti settled down grimly. "Then there's a geepee on the loose, intent on sabotage?"

"I'm afraid so," he admitted worriedly.

"What are we standing here for? We'll go back to controls and pick up the robot on radio. What it damaged, it can repair." She was partly turned around now and saw Docchi's face. "Don't tell me," she said. "I suppose I should have thought of it. The signal doesn't work inside the ship."

Docchi nodded. "It doesn't. Robots are never used aboard, so the control is set in the bow antenna and the ship, of course, is insulated."

"Well," said Anti happily, "we've got a robot hunt ahead of us."

"We do. And our bare hands to hunt it with."

"Oh, come now! It's not as bad as all that. Look, the geepee was back here when the rockets stopped. Could it get by the control compartment without our seeing it?"

"It couldn't. There are two corridors leading through the compartment, one on each side of the ship."

"That's what I thought. We came down one corridor and no geepee was in it. It has to be in the other. If it goes into a cabin, a light will shine on the outside. It can't really hide from us."

"Sure, we'll find out where it is. But what are we going to do with it when we find it?"

"I was thinking," said Anti. "Can you get around me when I'm standing like this?"

"I can't."

"Neither can a geepee. All I need is a toaster, or something that looks like one, and I can drive the robot into the control compartment for Jordan to pick off." Determinedly, she began to move toward the opposite corridor. "Hurry back to Jordan and tell him what we're doing. There ought to be another toaster on the ship. Probably there's one somewhere in the control compartment. Bring it back to me."

Docchi bit his lip and stared at the back of the huge woman. "All right," he answered. "But stay where you are. Don't try anything until I get back."

Anti laughed. "I value my big, fat life," she said. There were other things she valued, but she didn't mention them.

Docchi went as fast as the magneslippers would allow, which wasn't very fast. The strategy was simple, but it didn't follow that it was sound—a toaster for Jordan and one for Anti, if another could be found.

Anti would block the corridor. A geepee might go through her, but it could never squeeze past her. The robot would have to run for it. If it came toward Anti, she might be able to burn it do............
