Of course, like the GSEA, I didn’t exactly know where Miranda was, either, although I suspected she was underground somewhere in the wooded Adirondack Mountains near East Oleanta. But I didn’t have the faintest idea how to actually find her.

Until Lizzie Francy.

I went back to see Lizzie Francy the same evening I first told her about simple computer operations, the day after I’d put a medpatch on her. I’d seen how Billy Washington changed color when I’d asked about Eden. That old man was the worst liar I’d ever seen. He knew something about Eden; he was hopelessly in love with the much tougher and more conventional Annie; Lizzie could do anything with him she chose. Poor Billy.

Lizzie still sat on the spectacularly ugly plastisynth sofa, dressed in a pink nightshirt, her hair in sixteen braids tied with pink ribbon. Electronic parts lay scattered over her blanket. I viewed her around Billy, who opened the door but didn’t want to let me in.

“Lizzie’s asleep, her.”

“No, she isn’t, Billy. She’s right there.”

“Vicki!” Lizzie cried in her little-girl voice, and something unexpected turned over in my chest. “You’re here!”

“She’s sick, her, too sick for no company.”

“I’m fine, me,” Lizzie said. “Let Vicki in, Billy. Pleeeaasse?”

He did, unhappily. Annie wasn’t around. I said, “What have you got there, Lizzie?”

“The apple peeler ’bot from the cafe kitchen,” she said promptly, and without guilt. Billy winced. “It broke and I took it apart, me, to see if I can fix it.”

“And can you?”

“No. Can you?” She looked at me with hungry brown eyes. Billy left the apartment.

“Probably not,” I said. I’m not a ’bot tech. But let me see.”

“I’ll show you, me.”

She did. She put together the pieces of the peeler ’bot, which had a simple standard Kellor chip powered by Y-energy. I went to school with Alison Kellor, who always professed a world-weary disdain for the electronic empire she would inherit. Lizzie assembled the ’bot in about two minutes and showed me how it wouldn’t work despite an active chip. “See this little teeny bit here, Vicki? Where the peeler arm fits onto the ’bot? It’s sort of melted, it.”

I said, “What do you think did that?”

The big brown eyes looked at me. “I don’t know, me.”

“I do.” The destroyed joint was duragem. Had been duragem, until attacked by the renegade replicating dissembler.

“What melted it, Vicki?”

I turned the ’bot over in my hands, looking for other duragem joints. They were there, between the less durable but cheaper nonmoving plastics. The others weren’t “sort of melted, them.” But neither were a few of the duragem parts.

“What melted it, Vicki? Vicki?” I felt a hand on my arm.

Why hadn’t the other duragem joints been attacked? Because the dissembler was clocked. It had self-destructed after a certain time, and had also stopped replicating after making a certain number of copies of itself. Much — maybe even most — nanotech had this safety feature.

Lizzie shook my arm. “What melted it, Vicki? What?”

“A tiny little machine. Too small to see.”

“The duragem dissembler? The one I saw, me, on the newsgrid?”

Then I did look up. “You watch the donkey newsgrids?”

She gave me a long, serious look. I could see this was an important decision for her: to trust me or not. Finally she said, as if it were an answer, “I’m almost twelve, me. My mama, she still thinks I’m six.”

“Ah,” I said. “So how does a twelve-year-old see donkey news-grids? They’re never on at the cafe.”

“Nothing’s on in the middle of the night. Some nights. I go there, me, and watch.”

“You sneak out?”

She nodded solemnly, sure that this admission would bring down the world. She was right. I had never imagined a Liver kid with that much ambition or curiosity or intelligence or guts. Lizzie Francy was not supposed to exist. She was as much a wild card as the duragem dissembler, and as unwelcome. To both Livers and donkeys.

And then I saw a way to use her difference.

“Lizzie, how’d you like to make a bargain with me?”

She looked wary.

“If you tell me what I want to know, I’ll help you learn as much as I can about how machines work.”

Lizzie’s face changed. She leapt on my words like the promising little piranha she was.

“You promised, you. Vicki, I heard you, me, and that was a promise. You say you’ll help me find out everything about how machines work!”

“I said, ‘as much as I can.’ Not everything.”

“But you promised, you.”

“Yes, yes, I promised. But in return you have to answer all the questions I have.”

She considered this, her head cocked to one side, the sixteen pink-tied braids all sticking out in different directions. She didn’t see any major trap. “All right.”

“Lizzie, have you ever heard of Eden?”

“In the Bible?”

“No. Here, near East Oleanta.”

Despite our agreement, she hesitated. I said, “You promised, too.”

“I heard, me, Billy and Mama talking about it. Mama said Eden don’t never exist except in the Bible. Billy, he said he wasn’t so sure, him. He said maybe it was a place in the mountains or the woods that donkeys don’t know about, and Livers might work there, them. They thought I was asleep.”

A place donkeys don’t know about. Meaning, to East Oleanta, government donkeys, practically the only kind a town like this ever saw.

“Does Billy ever go off alone into the woods? Without your mama?”

“Oh, yeah, he likes it, him. Mama wouldn’t never go off in the woods. She’s too fat.” Lizzie said this matter-of-factly; for some reason I thought suddenly of Desdemona, seizing my soda-can bracelet without guilt or evasion.

“How often does he go? How long does he stay?”

“Every couple of months, him. For five or six days. Only now he’s getting too old, him, Mama says.”

“Does that mean he won’t go any more?”

“No, he’s going next week, him. He told her he got to, unless something important breaks down and he’s afraid, him, to leave us alone. But we got the food.” She pointed to the pathetic piles of tasteless synthetic food rotting in buckets in the corners.

“When next week?”

“Tuesday.”

Lizzie knew everything. But more to the point — what did Billy know? Did he know where Miranda Sharifi was?

“What time does Billy leave when he goes to the woods?”

“Real early in the morning. Vicki, how are you going to teach me, you, everything about machines? When do we start, us?”

“Tomorrow.”

“Today.”

“You’re still recovering. You had pneumonia, you know. Do you know what that is?”

She shook her head. The silly pink ribbons bobbed. If this were my kid, I’d tie up her braids with microfilaments.

If this were my kid? Jesus.

“Pneumonia is a disease caused by bacteria, which is itself a tiny little living machine, which got destroyed in your body by another tiny living machine engineered to do that. And that’s where we’ll start tomorrow. If you have the right codes there are programs you can access on the hotel terminal, where people hardly ever go…” For the first time it occurred to me that Annie would object vigorously to this tutorial program. I might be educating Lizzie in the middle of the night.

“What codes?” Her eyes were bright and sharp as carbon-rod needles.

“I’ll show you tomorrow.”

“I already reprogrammed, me, the servoentrance door at the cafe to let me and Mama in. I can understand about the hotel terminal. Just say, you, a little bit how…”

“Good-bye, Lizzie.”

“Just say how—”

“Good-bye.”

As I closed the door, she was once more taking apart the peeler ’bot.
