'I thought I'd find you here, Willi.'
Kris Cardenas came striding out of the shadows. Despite her years on the Moon she still kept a deep
tan, thanks to ultraviolet lamps. To Doug she looked like a California surfer: broad shoulders, trim
build, sparkling blue eyes. She kept her sandy hair clipped short and wore a loose, comfortable
jumpsuit of pastel yellow. No jewelry, no decorations of any kind. From the easy-going, no-fuss look
of her, you would never suspect she was a Nobel laureate nanotech researcher.
'Our young friend here wants me to make everyone bulletproof,' Zimmerman said, grudgingly dragging
his bulk to one side of the sofa so Cardenas could sit beside him. Even on the Moon, Zimmerman did
not move fast.
'No,' Doug protested. 'All I'm asking-'
'You think perhaps that the nanomachines you carry inside you will protect you against machine guns?
They saved your life twice before, but they don't make you a superman.'
'Willi,' said Cardenas, with a charmer's smile, 'why don't you let Doug tell you what he wants?'
'Medical supplies,' Doug blurted before Zimmerman could say another word. 'If we're cut off from
Earth for more than a couple of months we're going to run short of medical supplies. I was wondering
if nanomachines could be developed to replace or augment some of the pharmaceuticals we use.'
'How can I do that? Your own silly rules prevent me from using nanomachines anywhere inside
Moonbase, except in my laboratory,' Zimmerman grumbled.
'The safety rules, yes, I know,' said Doug.
'Even my furniture I had to make in my lab and then get a crew to schlep into here.'
'We can't take the chance of having nanomachines propagate inside the base.'
'Nonsense,' Zimmerman muttered. 'Superstition.'
Cardenas stepped in again. 'So you're ready to bend the safety rules, Doug?'
'We'll have to, at least a little.'
'And you need help with medical supplies, right?'
'Right.'
'Aspirin maybe?' Zimmerman grumbled suspiciously.
'More than aspirin,' said Doug.
'Specifically?'
'I don't know, specifically. You'll have to talk to the medical staff.'
'I will have to? These are your orders? You are the field marshal now and I am under your command?'
'That's exactly right,' said Cardenas, still smiling sweetly. 'That's the situation we're in, Willi, and we've
all got to do everything we can to help.'
Zimmerman mumbled something in German.
'Otherwise,' Cardenas warned, 'we'll all be sent back to Earth - and never allowed to work on
nanotechnology again.'
For a long moment the old man said nothing. Then, with an enormous groaning sigh, he nodded
unhappily. It made his cheeks waddle.
'Yah,' he said at last. 'I will speak with your medical staff. I might as well. There is nothing else for me
to do, now that Kiribati no longer takes our transmissions.'
Lunar University's courses had been beamed to Kiribati for distribution to students around the world.
That had worked well enough for the engineering and humanities curricula. But since most nations
forbade teaching nanotechnology openly, the nanotech courses had to be packaged separately and
delivered in clandestine ways. Cardenas often complained that she felt as if she were dealing in
pornographic videos, 'shipping them out in plain brown wrappers'.
'When this is over you can start teaching again,' Doug said.
'You think we will win?' Zimmerman's tone made it clear that he had no such illusions.
'We'll try,' said Doug, getting to his feet.
'And we'll do everything we can to help,' Cardenas said. 'Won't we, Willi?'
'Yah.' Without enthusiasm.
'Thanks,' Doug said. 'I appreciate whatever you can do.'
He started off toward the door, threading his way through the equipment standing idle in the shadows
of the unlit studio. Behind his retreating back, Cardenas leaned toward Zimmerman and whispered a
suggestion to him. The old man frowned, then shrugged.
'Maybe we can make you invisible,' Zimmerman called after Doug, his voice echoing through the
darkened studio.
Doug looked back over his shoulder and suppressed the urge to laugh. That'd be great,' he said,
thinking that bulletproof would be a lot better.
Back in his quarters, Doug lit up his wall screen, scanning the computer's personnel files for anyone
who had military experience. It was a fruitless search. Moonbase's employees were scientists and
engineers, technicians and medical doctors, computer analysts, nurses, construction specialists,
