Lilo pointed out to Vaffa that it would still be possible to use the small rocket scooter based on Poseidon to rendezvous with the larger ship as it passed them. Vaffa thought it over, and eventually agreed. The Vaffas might have suspected some sort of plot, but felt secure enough about the scooter. It had the peculiar property of exploding if it passed a certain distance from the gravity well of Jupiter: another of the innumerable precautions against escape.

The scooter was a standard model, little more than an engine with a framework of seats attached. Three of the four seats were filled with silvery bodies as Vaffa matched velocity with the mammoth tug.

They had come in laterally from the front, allowing the tug to catch up with them. None of them wanted to get anywhere near the aft end of the other ship. Somewhere back there, suspended by invisible lines of magnetic force, was a black hole smaller than a pinhead but massing as much as a medium-sized asteroid. It would not do to get too close to it.

Lilo was trying to juggle all the factors in her head, looking for the chance which, when it came, might last only a fraction of a second. One crew member in the tug. Vaffa the only one in communication with him. The homemade gas capsule hidden in the atmosphere probe, the probe strapped to the outside of the scooter. Vaffa's weapon strapped to his side. Times and courses: twenty minutes to castoff, when the tug would let go of the hole and pull away from it; thirty minutes to the course change that would put the probe on the right trajectory to graze the Jovian atmosphere.

Cathay was to try to get into the tug first—the lock would take only one person at a time. After that, it was up to him. If he gassed the man inside, they were committed to trying to overpower Vaffa. They might do it, with the help of surprise.

Ten meters away, Vaffa cast a magnetic line to the tug and warped the scooter in close. The three of them jumped free and began to lash the scooter. Lilo saw Cathay move toward the compartment where the gas bomb was hidden, and tried to get between him and Vaffa.

"I know what you're doing," Vaffa said quietly.

"Inspection," Lilo said, desperately. "We have to—"

"Let me see that." He was reaching for his laser.

Lilo put one foot on the scooter and dived at him. Her head hit him in the stomach, doubling him up. She saw the laser swing by her face, his grip loosened for a moment. She chopped at his wrist, and the gun fell away from them, spinning free.

"The lock!" she cried. "Get in the lock! Hurry!" She couldn't see if Cathay was moving. Vaffa swung at her chin, but the force of his blow turned his body enough so that he missed her. It had been instinctive, but the wrong thing to do in weightlessness. He saw his mistake and was about to switch tactics when he realized he had moved out of reach of the ship and scooter. He grabbed for Lilo's foot as it came by him, just as she reached for a strut on the scooter. He pulled, she kicked, and her hand lost its grip. The two of them drifted away from the scooter, not fast, but there was no way back under their own power. Unless...

Lilo kicked again, hitting him in the jaw. He hung on desperately until she had to stop because she was no longer facing the ship. Her idea was to push him from her and get back that way. But he saw it, too, and as soon as she stopped kicking he started to climb her leg. In another second he would be pushing her away from the ship.

She kicked again, shaking him back to her ankle, and kept on kicking, this time with both feet. His ribs seemed to crunch under her heel as she connected. Savagely, she aimed for the same spot again. He doubled over in pain, and his hand released her. She was floating free, spinning very slowly.

It didn't look too bad, if Cathay could get control of the ship. She saw Vaffa turning end over end at about one revolution per second, then she spotted the tug. She had drifted about fifty meters away from it. It was impossible to tell yet which way she was moving.

Then she heard Vaffa calling the ship.

"Cathay! He's talking to the pilot. You've got to get him before he can call back to Poseidon and tell them what's happened, or..." She stopped, realizing he wouldn't be able to hear her if he was in the ship and in a position to do anything about it. If he wasn't in the ship, it was all over anyway.

Three long minutes dragged by. The only thing Lilo learned for sure was that she was not getting closer to the ship. She was moving away. And she didn't care for the direction, either. Ahead of her, Jupiter was growing, filling the sky with the round circle of the tug exactly centered in it, seen from the stern. Somewhere in the direction she was moving was a black hole.

"You'll get there first," she yelled, feeling lightheaded. "How does it feel, Vaffa?"

There was no reply for a while. The voice that finally came was strained, full of pain.

"Why did you do it?"

"I don't think I could explain it to you. But it almost worked. Still might. I've got my fingers crossed."

There was no answer. Lilo thought she heard a moan. In a few seconds she was sure of it. There was an incoherent noise that stood her hair on end even after she had identified it. It was a subvocalized scream, picked up by the voder in Vaffa's throat and amplified as sheer agony. Then silence. Lilo began to worry. She hadn't hit him that hard.

"Lilo? Can you hear me? Are you alive?"

"Yes, I'm here! You got in!"

"It took me a while to get my radio tuned to the suit frequency. Damn, I wish it was you in here. All these buttons scare me." They had trained him for hours on mock-ups Vejay had built. He could punch in a course, if it came to that, and as long as nothing went wrong he could fly it.

"Never mind about that. You've got to cut the hole loose, and fast. I think Vaffa's dead, and I'm afraid what killed him was the magnetic field interfering with his suit generator. I'm not enough of a physicist to know just what a powerful magnetic field can do, but it didn't sound pleasant. Can you... I mean, in a hurry, you understand? I don't know how long it will be—" She stopped herself when she realized she was panicking.

"Just a minute. I'll do it." She heard him muttering to himself, then a cry of triumph. "There. They're all reading zero. Did that do it?"

"I'll know in a minute. Now we've got to think fast. Neither of us wants to fall into the thing. You're going to have to move the ship a little farther out. Vejay said the gravity field of a hole is very weak at just a small distance, but it increases sharply the closer you get to it. I'll be all right. But you have to save the ship so we can get back and—"

"It's too late for that. I didn't have time to tell you, but the pilot talked to Poseidon before I gassed him. They know we've taken over. They'll be waiting for us. It's no good, Lilo." She could hear him choking. Oh, God. Vejay and Niobe and Cass, waiting outside on the chance Lilo and Cathay would return in control of the tug...

"Cathay, we talked about that. They know what to do. If they're suspected of anything, they'll hole up with Cass and wait it out. We've got to get away now, so we can come back with some weapons we can use."

"You're right. We—"

Everything seemed to happen at once. There was a bright flash behind Lilo. She started to turn, thought better of it. It had to be Vaffa impacting the hole, being condensed by the awful gravity into degenerate matter, releasing all the energy stored in the atoms of his body as raw radiation.

That was bad enough, but ahead of her the tug was moving. A thin spear of light shot from it, angled away from her, and the engines continued to burn.

Jupiter had swallowed up the sky. It was beautiful. Even knowing it would be her death, Lilo had to admit that. And she preferred it to the hole, though her death would not be as quick.
