The one holding the notepad read aloud: "You just typed in: ‘925 999 994 know. reboot’. That doesn’t sound like journalism to me, Victor."
"Hey, I was being dramatic." He thought for a second, and then laughed. "It doesn’t matter anymore! I got the warning out. You won’t remember any of this after you’re rebooted."
Dixie Mae stepped toward him. "And you won’t remember that I broke your neck."
Victor tried to look suave and jump backwards at the same time. "In fact, I will remember, Dixie Mae. See, once you’re gone, I’ll be merged back into my body in Doc Reich’s lab."
"And we’ll be dead again!"
Ellen held up the notepad. "Maybe not as soon as Victor thinks. I notice he never got past the first line of his message; he never pressed return. Now, depending on how faithfully this old notepad’s hardware is being emulated, his treason is still trapped in a local cache–and Reich is still clueless about us."
For a moment, Victor looked worried. Then he shrugged. "So you get to live the rest of this run, maybe corrupt some other projects–ones a lot more important than you. On the other hand, I did learn about the email. When I get back and tell Doc Reich, he’ll know what to do. You won’t be going rogue in the future."
Everyone was silent for a second. The wind whistled across the yellow-blue sky above the pit.
And then the twins gave Victor the sort of smile he had bestowed on them so often. The token holder said, "I think your mouth is smarter than you are, Victor. You asked the right question a second ago: Why doesn’t Gerry Reich upload himself to be the spy? Why does he have to use you?"
"Well," Victor frowned. "Hey, Doc Reich is an important man. He doesn’t have time to waste with security work like this."
"Really, Victor? He can’t spare even a copy of himself?"
Dixie Mae got the point. She closed in on Victor. "So how many times have you been merged back into your original?"
"This is my first time here!" Everybody but Victor laughed, and he rushed on, "But I’ve seen the merge done!"
"Then why won’t Reich do it for us?"
"Merging is too expensive to waste on work threads like you," but now Victor was not even convincing himself.
The Ellens laughed again. "Are you really a UCLA journalism grad, Victor? I thought they were smarter than this. So Gerry showed you a re-merge, did he? I bet that what you actually saw was a lot of equipment and someone going through very dramatic convulsions. And then the ‘subject’ told you a nice story about all the things he’d seen in our little upload world. And all the time they were laughing at you behind their hands. See, Reich’s upload theory depends on having a completely regular target. I know that theory: the merge problem–loading onto an existing mind–is exponential in the neuron count. There’s no way back, Victor."
Victor was backing away from them. His expression flickered between superior sneer and stark panic. "What you think doesn’t matter. You’re just going to be rebooted at 5 p.m. And you don’t know everything." He began fiddling with the fly zipper on his pants. "You see, I–I can escape!"
"Get him!"
Dixie Mae was closest. It didn’t matter.
There was no hazy glow, no sudden popping noise. She simply fell through thin air, right where Victor had been standing.
She picked herself up and stared at the ground. Some smudged footprints were the only sign Victor had been there. She turned back to the twins. "So he could re-merge after all?"
"Not likely," said the token holder. "Victor’s zipper was probably a thread self-terminate mechanism."
"His pants zipper?"
They shrugged. "I dunno. To leak out? Gerry has a perverse sense of humor." But neither twin looked amused. They circled the spot where Victor had left and kicked unhappily at the dirt. The token holder said, "Cripes. Nothing in Victor’s life became him like the leaving it. I don’t think we have even till ‘5 p.m.’ now. A thread terminate signal is just the sort of thing that would be easy to detect from the outside. So Gerry won’t know the details, but he–"
"–or his equipment–"
"–will soon know there is a problem and–"
"–that it’s probably a security problem."
"So how long do we have before we lose the day?" said Dixie Mae.
"If an emergency reboot has to be done manually, we’ll probably hit 5 p.m. first. If it’s automatic, well, I know you won’t feel insulted if the world ends in the middle of a syllable."
"Whatever it is, I’m going to use the time." Dixie Mae picked her email up from where it lay by the vault entrance. She waved the paper at the impassive steel. "I’m not going back! I’m here and I want some explanations!"
Nothing.
The two Ellens stood there, out of ideas and looking unhappy–or maybe that amounted to the same thing.
"I’m not giving up," Dixie Mae said to them, and pounded on the metal.
"No, I don’t think you are," said the token holder. But now they were looking at her strangely. "I think we–you at least–must have been through this before."
"Yeah. And I must have messed up every time."
"No ... I don’t think so." They pointed at the email that she held crumpled in her hand. "Where do you think all those nasty secrets come from, Dixie Mae?"
"How the freakin’ heck do I know? That’s the whole reason I–" and then she felt smart and stupid at the same time. She leaned her head against the shadowed metal. "Oh. Oh oh oh!"
She looked down at the email hardcopy. The bottom part was torn, smeared, almost illegible. No matter; that part she had memorized. The Ellens had gone over the headers one by one. But now we shouldn’t be looking for technical secrets or grad student inside jokes. Maybe we should be looking for numbers that mean something to Dixie Mae Leigh.
"If there were uploaded souls guarding the door, what you two have already done ought to be enough. I think you’re right. It’s some pattern I’m supposed to tap on the door." If it didn’t work, she’d try something else, and keep trying till 5 p.m. or whenever she was suddenly back in Building 0994, so happy to have a job with potential... .
The tree house in Tarzana. Dixie Mae had been into secret codes then. Her childish idea of crypto.
She and her little friends used a tap code for sending numbers. It hadn’t lasted long, because Dixie Mae was the only one with the patience to use it. But–
"That number, ‘7474’," she said.
"Yeah? Right in the middle of the fake message number?"
"Yes. Once upon a time, I used that as a password challenge. You know, like ‘Who goes there’ in combat games. The rest of the string could be the response."
The Ellens looked at each. "Looks too short to be significant," they said.
Then they both shook their heads, disagreeing with themselves. "Try it, Dixie Mae."
Her "numbers to taps" scheme had been simple, but for a moment she couldn’t remember it. She held the paper against the vault and glared at the numbers. Ah. Carefully, carefully, she began tapping out the digits that came after "7474." The string was much longer than anything her childhood friends would have put up with. It was longer than anything she herself would have used.
"Cool," said the token holder. "Some kind of hex gray code?"
Huh? "What do you expect, Ellen? I was only eight years old."
