"Governor Dobrynin's plan has the backing of my government. I have spoken with them and they will stand behind it. And someday, Mr. Pecci, I would very much like to know how you can be so sure what it is the Cantons want." At this the man was silent.

"What say you, Vice-Minister? Has this plan your consent?"

The vice-minister rose. "Well. I am sure the Minister will want to know all the details, and I am sure he will question the risk. But for myself, you have my approval. And I think when the Minister is briefed in full, he will agree that we have little choice."

"Thank you, Peter," said Dobrynin. "I will see that he is given a full report, and that he is kept informed throughout." He turned back to the others. "Now, gentlemen, if you will excuse me. My engineers and I have much work to do. Doctor Stein, we could use your help as well."

With that Dobrynin left the room, followed by five others. Salnikov watched them go, then lowered his head, and returned to his ship.

The charges had been laid. Two hundred kilometers beneath the surface, six old-style nuclear explosives had been set in a flat, star-shaped pattern—-this, in the heart of a solidified iron and nickel flow one hundred and sixty kilometers across, rising directly from the planet's core. Ironically, the massive upheaval which caused it had occurred many thousand years before, during yet another violent passage of the planet's equilibrium point. If such a bullet could be launched at the station, it would indeed be hard to knock down, though the full effect on the planet itself could hardly be calculated. Between the force of the blast and the current instability, almost anything was possible. Dobrynin had no illusions about serious mining for at least a year—-that things could ever again be the way they were before. But it had to be tried.

It has gone well enough so far, he thought. Five dead and seventeen wounded, but still, well enough. This is the hard part now. I don't mind dying, if I have to. But I don't want to.

MAYBE YOU WON'T DIE, said a voice. Yes, and maybe I will. I hope that my son understands. I hope he sees that I have no choice. BUT YOU HAVE A CHOICE. Do I? If there is a choice then I don't see it. Not without surrendering all that we have worked for. No. I cannot go back.

His son entered the room, followed by Stein and Alexander Dimitriev, his chief engineer. At his gesture they were seated at the table across from him.

"Thomas, Alexander. Now we are come to the hard part: how to detonate safely and accurately. As you know, in this, timing is everything. Everything. If we miss by only a few seconds, we doom the planet to extinction."
