He paused and his tone became less casual. "During the last six months, I've concluded we've made a serious mistake in this. There are people operating under our very noses who have technology substantially in advance of pre-War levels."
"I hope you're not thinking of the Mongolian nationalists, sir. I tried to make it clear in my reports that their nuclear weapons were from old Soviet stockpiles. Most weren't usable. And without those bombs they were just pony sol-
"No, my dear Della, that's not what I am thinking of." He slid a plastic box across the table. "Look inside."
Five small objects sat in the velvet lining. Lu held one in the sunlight. "A bullet?" It looked like an 8-mm. She couldn't tell if it had been fired; there was some damage, but no rifling marks. Something dark and glossy stained the nose.
"That's right. But a bullet with a brain. Let me tell you how we came across that little gem.
"Since I became suspicious of these backyard scientists, these Tinkers, I've been trying to infiltrate. It hasn't been easy. In most of North America, we have tolerated no governments. Even though it's cost us on the impost, the risk of nationalism seemed too high. Now I see that was a mistake. Somehow they've gone further than any of the governed areas - and we have no easy way to watch them, except from orbit.
"Anyway, I sent teams into the ungoverned lands, using whatever cover was appropriate. In Middle California, for instance, it was easiest to pretend they were descendents of the old Soviet invasion force. Their instructions were to hang around in the mountains and ambush likely-looking travelers. I figured we would gradually accumulate information without any official raids. Last week, one crew ambushed three locals in the forests east of Vandenberg. The quarry had only one gun, a New Mexico 8-mm. It was nearly dark, but from a distance of forty meters the enemy hit every one of the ten-man crew - with one burst from the 8-mm.
"The New Mexico 8-mm only has a ten-round clip. That's - "
"A perfect target score, my dear. And my men swear the weapon was fired on full automatic. If they hadn't been wearing body armor, or if the rounds had had normal velocity, not one of them would have lived to tell the story. 'Ten armed men killed by one man and a handmade gun. Magic. And you're holding a piece of that magic. Others have been through every test and dissection the Livermore labs could come up with. You've heard of smart bombs? Sure, your air units in Mongolia used them. Well, Miss Lu, these are smart bullets.
"The round has a video eye up front, connected to a processor as powerful as anything we can pack in a suitcase - and our suitcase version would cost a hundred thousand monets. Evidently the gun barrel isn't rifled; the round can change attitude in flight to close with its target."
Della rolled the metal marble in her palm. "So it's under the control of the gunman?"
"Only indirectly, and only at `launch' time. There must be a processor on the gun that queues the targets, and chooses the firing instant. The processor on the bullet is more than powerful enough to latch the assigned target. Rather interesting, eh?"
Della nodded. She remembered how delicate the attack gear on the A51 1's had been - and how expensive. They'd needed a steady supply of replacement boards from Beijing. If these things could be made cheaply enough to throw away...?
Hamilton Avery gave a small smile, apparently satisfied with her reaction. "That's not all. Take a look at the other things in the box."
Della dropped the bullet onto the velvet padding and picked up a brownish ball. It was slightly sticky on her fingers. There were no markings, no variations in its surface. She raised her eyebrows.
"That is a bug, Della. Not one of your ordinary, audio bugs, but full video - we expect in all directions, at that. Something to do with Fourier optics, my experts tell me. It can record, or transmit a very short distance. We've guessed all this from x-ray micrographs of the interior. We don't even have equipment that can interface with it!"
"You're sure it's not recording right now?"
"Oh yes. They fried its guts before I took it. The microscopists claim there's not a working junction in there.
"Now I think you see the reason for all the precautions."
Della nodded slowly. The bobble bursts were not the reason; he expected their true enemies already knew all about those. Yes, Avery was being clever - and he was as frightened as his cool personality would ever allow.
They sat silently for about thirty seconds. The chopper made another turn, and the sunlight swept across Della's face. They were flying east over Long Beach toward Anaheim - those were the names in the history books anyway. The street pattern stretched off into gray-orange haze. It gave a false sense of order. The reality was kilometer on kilometer of abandoned, burned-out wilderness. It was hard to believe that this threat could grow in North America. But, after the fact, it made sense. If you deny big industry and big research to people, they will look for other ways of getting what they need.
...And if they could make these things, maybe they were clever enough to go beyond all the beautiful quantum-mechanical theories and figure a way to burst bobbles.
"You think they've infiltrated the Authority?"
"I'm sure of it. We swept our labs and conference rooms. We found seventeen bugs on the West Coast, two in China, and a few more in Europe. There were no repeaters near the overseas finds, so we think they were unintentional exports. The plague appears to spread from California."
"So they know we're on to them."
"Yes, but little more. They've made some big mistakes and we've had a bit of good luck: We have an informer in the California group. He came to us less than two weeks ago, out of the blue. I think he's legitimate. What he's told us matches our discoveries but goes a good deal further. We're going to run these people to ground. And do it officially. We haven't made an example of anyone in a long time, not since the Yakima incident.
"Your role in this will be crucial, Della. You are a woman, and outside the Authority the frailer sex is disregarded nowadays."
Not only outside the Authority, thought Della.
"You'll be invisible to the enemy, until it's too late."
"You mean a field job?"
"Why, yes, my dear. You've certainly had rougher assignments."
"Yes, but-" but I was a field director in Mongolia.
Avery put his hand on Della's. "This is no demotion. You'll be responsible only to me. As communications permit, you'll control the California operation. But we need our very best out there on the ground, someone who knows the land and can be given a credible cover." Della had been born and raised in San Francisco. For three generations, her family had been 'furbishers - and Authority plants.
"And there is a very special thing I want done. This may be more important than all the rest of the operation." Avery laid a color picture on the table. The photo was grainy, blown up to near the resolution limit. She saw a group of men standing in front of a barn: northern farmers - except for the black child talking to a tall boy who carried an NM 8-mm. She could guess who these were.
"See the guy in the middle - by the one with the soldier frizz."
His face was scarcely more than a blotch, but he looked perfectly ordinary, seventy or eighty years old. Della could walk through a crowd in any North American enclave and see a dozen such.
"We think that's Paul Hoehler." He glanced at his agent. "The name doesn't mean anything to you, does it? Well, you won't find it in the history books, but I remember him. Back in Livermore, right before the War. I was just a kid. He was in my father's lab and... he's the man who invented the bobble."
