Other Worlds Than These

“Not in that reality. The other me phoned you. You were staying at the Holiday Inn. You knew nothing of Andrea having had any accident. So my other wife…” Joe allowed himself a quick smile. “The other version of Rachel called Andrea. And they spoke. Turned out Andrea had been hit by a car, but she’d barely been bruised. They hadn’t even called an ambulance.”

Mick absorbed what his friend had to say, then said, “I can’t deal with this, Joe. I don’t need to know it. It isn’t going to help.”

“I think it is. We were set up to run the nervelink experiment as soon as we had a solid lock, one that we could trust to hold for the full million seconds. This is it. The only difference is it doesn’t have to be me who goes through.”

“I don’t understand.”

“I can put you through, Mick. We can get you nervelinked tomorrow morning. Allowing for a day of bedding in and practice once you arrive in the other reality…well, you could be walking in Andrea’s world by Monday afternoon, Tuesday morning at the latest.”

“But you’re the one who is supposed to be going through,” Mick said. “You’ve already had the nervelink put in.”

“We’ve got a spare,” Joe said.

Mick’s mind raced through the implications. “Then I’d be controlling the body of the other you, right?”

“No. That won’t work, unfortunately. We’ve had to make some changes to these nervelinks to get them to work properly through the correlator, with the limited signal throughput. We had to ditch some of the channels that handle proprioceptive mapping. They’ll only work properly if the body on the other end of the link is virtually identical to the one on this side.”

“Then it won’t work. You’re nothing like me.”

“You’re forgetting your counterpart on the other side,” Joe said. He glanced past Mick at Bill and Rachel, raising his eyebrows as he did so. “The way it would work is, you come into the lab and we install the link in you, just the same way it happened for me yesterday morning. At the same time your counterpart in Andrea’s world comes into his version of the lab and gets the other version of the nervelink put into him.”

Mick shivered. He’d become used to thinking about the other version of Joe; he could even begin to accept that there was a version of Andrea walking around somewhere who was still alive. But as soon as Joe brought the other Mick into the argument, he felt his head begin to unravel.

“Wouldn’t he—the other me—need to agree to this?”

“He already has,” Joe said solemnly. “I’ve been in touch with him. The other Joe called him into the lab. We had a chat over the videolink. He didn’t go for it at first—you know how you both feel about nervelinking. And he hasn’t lost his version of Andrea. But I explained how big a deal this was. This is your only chance to see Andrea again. Once this window closes—we’re talking about no more than eleven or twelve days from the start of the lock, by the way—we’ll never make contact with another reality where she’s alive.”

Mick blinked and placed his hands on the table. He felt dizzy with the implications, as if the kitchen was swaying. “You’re certain of that? You’ll never open another window into Andrea’s world?”

“Statistically, we were incredibly lucky to get this one chance. By the time the window closes, Andrea’s reality will have diverged so far from ours that there’s essentially no chance of ever getting another lock.”

“Okay,” Mick said, ready to take Joe’s word for it. “But even if I agree to this—even if the other me agrees to it—what about Andrea? We weren’t seeing each other.”

“But you wanted to see her again,” Bill said quietly.

Mick rubbed his eyes with the palms of his hands, and exhaled loudly. “Maybe.”

“I’ve spoken to Andrea,” Rachel said. “I mean, Joe spoke to himself, and the other version of him spoke to the other Rachel. She’s been in touch with Andrea.”

Mick hardly dared speak. “And?”

“She says it’s okay. She understands how horrible this must be for you. She says, if you want to come through, she’ll meet you. You can spend some time together. Give you a chance to come to some kind of…”

“Closure,” Mick whispered.

“It’ll help you,” Joe said. “It’s got to help you.”

SUNDAY

The medical center was normally closed on weekends, but Joe had pulled strings to get some of the staff to come in on Sunday morning. Mick had to sit around a long time while they ran physiological tests and prepared the surgical equipment. It was much easier and quicker for tourists, for they didn’t have to use the modified nervelink units Joe’s team had developed.

By the early afternoon they were satisfied that Mick was ready for the implantation. They made him lie down on a couch with his head encased in a padded plastic assembly with a hole under the back of the neck. He was given a mild, local anesthetic. Rubberized clamps whirred in to hold his head in position with micromillimeter accuracy. Then he felt a vague impression of pressure being applied to the skin on the back of his neck, and then an odd and not entirely pleasant sensation of sudden pins and needles in every part of his body. But the unpleasantness was over almost as soon as he’d registered it. The support clamps whirred away from his head. The couch tilted up, and he was able to get off and stand on his feet.

Mick touched the back of his neck, came away with a tiny smear of blood on his thumb.

“That’s it?”

“I told you there was nothing to it,” Joe said, putting down a motorcycling magazine. “I don’t know what you were so worried about.”

“It’s not the nervelink operation itself I don’t approve of. I don’t have a problem with the technology. It’s the whole system, the way it encourages the exploitation of the poor.”

Joe tut-tutted. “Bloody Guardian readers. It was you lot who got the bloody moratorium against air travel enacted in the first place. Next you’ll be telling us we can’t even walk anywhere.”

The nurse swabbed Mick’s wound and applied a bandage. He was shunted into an adjoining room and asked to wait again. More tests followed. As the system interrogated the newly embedded nervelink, he experienced mild electrical tingles and strange, fleeting feelings of dislocation. Nothing he reported gave the staff any cause for alarm.

After Mick’s discharge from the medical center, Joe took him straight down to the laboratory. An electromagnetically shielded annex contained the couch Joe intended to use for the experiment. It was a modified version of the kind tourists used for long-term nervelinking, with facilities for administering nutrition and collecting bodily waste. No one liked to dwell too much on those details, but there was no way around it if you wanted to stay nervelinked for more than a few hours. Gamers had been putting up with similar indignities for decades.

Once Mick was plumbed in, Joe settled a pair of specially designed immersion glasses over his eyes, after first applying a salve to Mick’s skin to protect against pressure sores. The glasses fit very tightly, blocking out Mick’s view of the lab. All he could see was a blue-gray void, with a few meaningless red digits to the right side of his visual field.

“Comfortable?” Joe asked.

“I can’t see anything yet.”

“You will.”

Joe went back into the main part of the basement to check on the correlation. It seemed that he was gone a long time. When he heard Joe return, Mick half-expected bad news—that the link had collapsed, or some necessary piece of technology had broken down. Privately, he would not have been too sorry were that the case. In his shocked state of mind in the hours after Andrea’s death, he would have given anything to be able to see her again. But now that the possibility had arisen, he found himself prone to doubts. Given time, he knew he’d get over Andrea’s death. That wasn’t being cold, it was just being realistic. He knew more than a few people who’d lost their partners, and while they might have gone through some dark times afterward, almost all of them now seemed
