Pickover nodded vigorously. “I live alone, and I don’t have many friends; I’m a quiet sort. There’s no one I’ve ever told, and no one who could have ever overheard me saying it, or seen me typing it in.”
“Somebody found it out,” said Raoul.
Pickover looked at me, then down at Raoul. “I think …” he said, beginning slowly, giving me a chance to stop him, I guess, before he said too much. But I let him go on. “I think that the information was extracted from a scan of my mind made by NewYou.”
Raoul crossed his arms in front of his chest. “Impossible.”
“What?” said Pickover, and “Why?” said I.
“Can’t be done,” said Raoul. “We know how to copy the vast array of interconnections that make up a human mind, and we know how to reinstantiate those connections in an artificial substrate. But we don’t know how to decode them; nobody does. There’s simply no way to sift through a digital copy of a mind and extract specific data.”
Damn! If Raoul was right—and he always was in computing matters— then all this business with Pickover was a red herring. There probably was no bootleg scan of his mind; despite his protestations of being careful, someone likely had just overheard his passphrase, and decided to go spelunking through his files. While I was wasting time on this, Joshua Wilkins was doubtless slipping further out of my grasp.
Still, it was worth continuing this line of investigation for a few minutes more. “Any sign of where the access attempt was made?” I asked Raoul.
He shook his head. “No. Whoever did it knew what they were doing; they covered their tracks well. The attempt came over an outside line— that’s all I can tell for sure.”
I nodded. “Okay. Thanks, Raoul. Appreciate your help.”
Raoul got up. “My pleasure. Now, how ’bout that drink.”
I opened my mouth to say yes, but then it hit me—what Wilkins must be doing. “Umm, later, okay? I’ve—I’ve got some more things to take care of here.”
Raoul frowned; he’d clearly hoped to collect his booze immediately. But I started maneuvering him toward the door. “Thanks for your help, Raoul. I really appreciate it.”
“Um, sure, Alex,” he said. He was obviously aware he was being given the bum’s rush, but he wasn’t fighting it too much. “Anytime.”
“Yes, thank you awfully, Mr. Santos,” said Pickover.
“No problem. If—”
“See you later, Raoul,” I said, opening the door for him. “Thanks so much.” I tipped my nonexistent hat at him.
Raoul shrugged, clearly aware that something was up, but not motivated sufficiently to find out what. He went through the door, and I hit the button that caused it to slide shut behind him. As soon as it was closed, I put an arm around Pickover’s shoulders, and propelled him back to the computer. I pointed at the line Raoul had highlighted on the screen, and read the ending of it aloud: “ ‘… dine at half past eight, enjoying seven courses.’ ”
Pickover nodded. “Yes. So?”
“Numbers are often coded info,” I said. ‘ “Half past eight; seven courses.’ What’s that mean to you?”
“To me?” said Pickover. “Nothing. I like to eat much earlier than that, and I never have more than one course.”
“But it could be a message,” I said.
“From who?”
There was no easy way to tell him this. “From you to you.”
He drew his artificial eyebrows together in puzzlement. “What?”
“Look,” I said, motioning for him to sit down in front of the computer, “Raoul is doubtless right. You can’t sift a digital scan of a human mind for information.”
“But that must be what Wilkins is doing.”
I shook my head. “No,” I said. “The only way to find out what’s in a mind is to ask it interactively.”
“But … but no one’s asked me my passphrase.”
“No one has asked this you. But Joshua Wilkins must have transferred the extra copy of your mind into a body, so that he could deal with it directly. And that extra copy must be the one that’s revealed your codes to him.”
“You mean … you mean there’s another me? Another conscious me?”
“Looks that way.”
“But … no, no. That’s … why, that’s illegal. Bootleg copies of human beings—my God, Lomax, it’s obscene!”
“I’m going to go see if I can find him,” I said.
“It,” said Pickover, forcefully.
“What?”
“It. Not him. I’m the only ‘him’—the only real Rory Pickover.”
“So what do you want me to do when I find it?”
“Erase it, of course. Shut it down.” He shuddered. “My God, Lomax, I feel so … so violated! A stolen copy of my mind! It’s the ultimate invasion of privacy …”
“That may be,” I said. “But the bootleg is trying to tell you something. He—it—gave Wilkins the passphrase, and then tacked some extra words onto it, in order to get a message to you.”
“But I don’t recognize those extra words,” said Pickover, sounding exasperated.
“Do they mean anything to you? Do they suggest anything?”
Pickover re-read what was on the screen. “I can’t imagine what,” he said, “unless … no, no, I’d never think up a code like that.”
“You obviously just did think of it. What’s the code?”
Pickover was quiet for a moment, as if deciding if the thought was worth giving voice. Then: “Well, New Klondike is circular in layout, right? And it consists of concentric rings of buildings. Half past eight—that would be between Eighth and Ninth Avenue, no? And seven courses—in the seventh circle out from the center? Maybe the damned bootleg is trying to draw our attention to a location, a specific place here in town.”
“Between Eighth and Ninth, eh? That’s a rough area. I go to a gym near there.”
“The old shipyards,” said Pickover. “Aren’t they there?”
“Yeah.” I started walking toward the door. “I’m going to investigate.”
“I’ll go with you,” said Pickover.
I looked at him and shook my head. He would doubtless be more of a hindrance than a help. “It’s too dangerous,” I said. “I should go alone.”
Pickover looked for a few moments like he was going to protest, but then he nodded. “All right. I hope you find Wilkins. But if you find another me …”
“Yes?” I said. “What would you like me to do?”
Pickover gazed at me with pleading eyes. “Erase it. Destroy it.” He shuddered again. “I never want to see the damned thing.”
I had to get some sleep—damn, but sometimes I do wish I were a transfer. I took the hovertram out to my apartment, and let myself have five hours—Mars hours, admittedly, which were slightly longer than Earth ones—and then headed out to the old shipyards. The sun was just coming up as I arrived there. The sky through the dome was pink in the east and purple in the west.
Some active maintenance and repair work was done on spaceships here, but most of these ships were no longer spaceworthy and had been abandoned. Any one of- them would make a good hideout, I thought; spaceships were shielded against radiation, making it hard to scan through their hulls to see what was going on inside.
The shipyards were large fields holding vessels of various sizes and shapes. Most were streamlined—even Mars’s tenuous atmosphere required that. Some were squatting on tail fins; some were lying on their bellies; some were supported by articulated legs. I tried every hatch 1 could see on these craft, but, so far, they all had their airlocks sealed tightly shut.
