them could see what would happen to any city on Earth if
one of the Belt ships decided to shift the orbit of a good-sized
asteroid so that it would strike Earth. A few hundred thousand tons of
rock coming in at ten miles per second would be far more devastating
than an expensive H-bomb.

"They wouldn't dare," Fergus said again.

"Nevertheless," Tarnhorst said, "in dealings of this kind we are
walking very close to the thin edge. We have to watch ourselves."

Commodore Sir Harry Morgan was herded into a prison cell, given a
shove across the smallish room, and allowed to hear the door slam
behind him. By the time he regained his balance and turned to face the
barred door again, it was locked. The bully-boys who had shoved him in
turned away and walked down the corridor. Harry sat down on the floor
and relaxed, leaning against the stone wall. There was no furniture of
any kind in the cell, not even sanitary plumbing.

"What do I do for a drink of water?" he asked aloud of no one in
particular.

"You wait till they bring you your drink," said a whispery voice a few
feet from his head. Morgan realized that someone in the cell next to
his was talking. "You get a quart a day--a halfa pint four times a
day. Save your voice. Your throat gets awful dry if you talk much."

"Yeah, it would," Morgan agreed in the same whisper. "What about
sanitation?"

"That's your worry," said the voice. "Fella comes by every Wednesday
and Saturday with a honey bucket. You clean out your own cell."

"I _thought_ this place smelled of something other than attar of
roses," Morgan observed. "My nose tells me this is Thursday."

There was a hoarse, humorless chuckle from the man in the next cell.
"'At's right. The smell of the disinfectant is strongest now. Saturday
mornin' it'll be different. You catch on fast, buddy."

"Oh, I'm a whiz," Morgan agreed. "But I thought the Welfare World took
care of its poor, misled criminals better than this."

Again the chuckle. "You shoulda robbed a bank or killed somebody. Then
theyda given you a nice rehabilitation sentence. Regular prison. Room
of your own. Something real nice. Like a hotel. But this's
different."

"Yeah," Morgan agreed. This was a political prison. This was the place
where they put you when they didn't care what happened to you after
the door was locked because there would be no going out.

Morgan knew where he was. It was a big, fortresslike building on
