sorry we missed so much of it. Perhaps you'd let me run it again sometime in the next few days."
Mac had been at a loss to reconcile the courtesy with the armament.
"If all you want is to see my library, the weapons are a bit uncalled for," he finally got out. "I don't
know what else I can offer you except accommodation and communication facilities. Do you have ship
trouble? Did I miss a distress call? Maybe I do pay too much attention to my sheets—"
"Not at all. We'd have been very disappointed if you had spotted our approach, since we made it as
unobtru-sive as possible. You are also wrong about what you can give us. Not to waste time, we have a
four--thousand-ton ship outside which we expect to mass up to ten thousand before we leave, with the
aid of your Class IV isotopes."
"Six thousand tons of nuclear fuel? You've been ex-panding your consciousness. It would take sixty
hours or more if I reprogrammed every converter in the place—only one of them is making Class IV
now, and the others are all running other orders. There's barely enough conversion mass in the place for
what you want, unless you start chipping rock out of the station itself. I'd guess that on normal priority
you'd get an order like that in about a year, counting administrative time for the initial request."
"We're not requesting. As you know perfectly well. You will do any programming necessary, without
regard to what is running now, and if necessary we will use station rock. I would have said you'd chip it
for us, but I admit there's a difference between the merely illegal and the impossible. Why do they keep a
wreck like you on duty out here?"
Hoerwitz flushed. He was used to this attitude from the young and healthy, but more accustomed to
having it masked by some show of courtesy.
"It's the only place I can live," he said shortly. "My heart, muscles, and bones can't take normal
gravity. Most people can't take free-fall—or rather, they don't like the consequences of the medication
needed to take It indefinitely. That makes no difference to me. I don't care about muscle, and I had my
family half a century ago. This job is good for me, and I'm good for it. For that reason, I don't choose to
ruin it. I don't intend to do any reprogramming for you, and I'd be willing to bet you can't do it yourself."
Smith's gun reappeared, and its owner looked at it thoughtfully. The old man nodded toward it and
went on, "That's an argument, I admit. I don't want to die, but if you kill me it certainly won't get you
further." Mac found that he wasn't as brave as his words sounded; there was an odd and uncomfortable
feeling in his stomach as he looked at the weapon. He must have covered it well, however, because after
a moment of thought the intruder put the gun away again.
"You're quite right," he said. "I have no intention of killing you, because I do need your help. We'll
have to use another method. Mr. Jones, please carry out our first stage of planned persuasion?"

Fifteen minutes later Hoerwitz was reprogramming the converters as well as he could with an
unusable left hand.
Smith, who had courteously introduced himself dur-ing the procedure, had gone to the trouble of
making sure his victim was right-handed before allowing Jones to start work. It would, as he said, be a
pity to slow the station manager down too much. The right hand could wait.
"How about my toes?" Hoerwitz had asked sarcastically, not yet fully convinced that the affair was
serious.
"It seems to have been proved that feet have fewer nerves and don't feel pain as intensely," replied
Smith. "Of course, the toes will still be there if we need them. Mr. Jones, start with the left hand."
Mac had decided almost at once that the visitors were sincere, but Jones had insisted on finishing his
job in workmanlike style. Smith had supported him.
"It would be a pity for you to get the idea that we weren't prepared to finish anything we started," he
pointed out.
As he floated in front of the monitor panels readjust-ing potentiometers and flow-control relays,
Hoerwitz thought furiously. He wasn't much worried about his guests actually getting away with their
stolen fuel; what he was now doing to the controls must be showing on repeaters in Elkhart, Papeete, and
