Adikor looked at Dern. “What about you?”

  The fat man nodded. “Ready.”

  “Whenever you want to proceed, then,” said Adikor to Ponter.

  Ponter gave Adikor a splayed-fingers gesture. “Let’s find our cousins.”

  “All right,” said Adikor. “Ten!”

  One Exhibitionist was standing next to Adikor; the other, next to Ponter.

  “Nine!”

  The three members of the High Gray Council looked at each other; more had wanted to attend, but it was decided that three was the maximum that could be risked.

  “Eight!”

  Dern pulled out some control buds on his console.

  “Seven!”

  Ponter looked over at Ambassador Prat; if she was the least bit nervous, she was hiding it well.

  “Six!”

  He then looked over his shoulder at Adikor’s broad back. They had deliberately not said any elaborate goodbyes last night; neither wanted to admit that if something went wrong, there was a chance that Ponter would never come home again.

  “Five!”

  And it wasn’t just Adikor he stood to lose. The thought of his children ending up with no parents so early in life had been Ponter’s biggest worry about repeating his journey.

  “Four!”

  A lesser—but still significant—worry was that Ponter would fall ill again in the Gliksin world, although doctors here had boosted his immune system, and Hak had been modified to constantly monitor his blood for foreign bodies.

  “Three!”

  There was also concern that either Ponter or Tukana might develop allergies to things on the other side.

  “Two!”

  And Ponter had some misgivings about the long-term stability of the gateway, which was, after all, based on quantum processes that were by their very nature inherently unpredictable. Still…

  “One!”

  Still, with all the potential problems, with all the potential negatives, there was one very positive aspect about returning to the Gliksin world…

  “Zero!”

  Ponter and Adikor simultaneously pulled buds on their control panels.

  Suddenly, a great roar came from the computing chamber, which was visible through a window in the control room. Ponter knew what was happening, although he’d never been a spectator to it before. Everything that wasn’t bolted down in the computing chamber was being shunted to the other universe. The glass-and-steel register cylinders—even the wonky one, number 69—stayed put, but all the air in the chamber was being swapped for a comparable mass in the other universe. When Ponter had been accidentally transferred over, the corresponding space on the other side had contained a giant acrylic sphere full of heavy water—the heart of a Gliksin neutrino detector.

  But this time, no heavy water came gushing through. The chamber had been drained before Ponter had returned, so that the damage his arrival had done to the acrylic sphere could be repaired.

  Right on cue, the gaudy probe—cylindrical, about an armspan long—tumbled through the blue fire that marked the portal, the light hugging the probe’s contours in profile as it did so. All that was visible now were the anchoring and telecommunications cables attached to the probe, pulled taut, disappearing into midair at about waist height. Ponter swung his attention to the large, wall-mounted monitor that had been added to the control room to display what the probe was seeing.

  And what it was seeing was—

  “Gliksins!” exclaimed Ambassador Prat.

  “I’d only half believed it,” said Councilor Bedros.

  Adikor turned to look at Ponter, grinning. “Anyone you know?”

  Ponter squinted at the scene. As before, the portal had appeared several body-heights above ground; the quantum-computing facility seemed to be slightly higher up and slightly to the north of the center of the neutrino-detector chamber. A dozen or more Gliksins were working inside the still-dry chamber. They were all clad in coveralls, and they all had those yellow plastic turtle shells on their heads. Most of the Gliksins had the same pale skin that Ponter’s people had, but two had dark brown skin. Ponter got the impression that almost all the workers were males, but it was so hard to tell with Gliksins. Of course, the one face he’d hoped to see was female, but there was no reason she should be doing repair work down at the bottom of a mineshaft.

  All the faces were looking directly at the probe, and several of the individuals were pointing with their scrawny arms.

  “No,” said Ponter. “Nobody I know.”

  The probe’s microphones were picking up sounds, all echoing weirdly in the cavernous chamber. Ponter couldn’t understand much of what was being said, but he did pick out his own name at one point. “Hak,” said Ponter, speaking to his Companion, “what are they saying?”

  Hak had a new voice now; while getting upgrade work done on his Companion, Ponter had had Kobast Gant program in a pleasant male voice that wasn’t based on anyone Ponter knew.

  Hak spoke through his external speaker, so that the entire assembled group could hear. “The male at the right side of the screen just invoked that thing they call God—apparently in this context, it’s an exclamation of surprise. The male next to him referred to the putative son of the God thing. And the woman next to him said, ‘Wholly feces.’”

  “Very strange,” said Tukana.

  “The male at the right,” continued Hak, “has now yelled for somebody out of our view to get Doctor Mah on the telecommunications link.”

  As Hak spoke, several of the humans came close to the probe. Ponter enjoyed hearing the gasps from the three High Gray Council members and Ambassador Prat as they got their first close-up views of the strange, pinched Gliksin faces, with their preposterously small noses.

  “Well,” said Dern, the roboticist, “it looks like we’ve reestablished contact, and it seems conditions on the other side are suitable.”

  The three High Gray Council members conferred for a few beats, then Bedros nodded. “Let’s do it,” he said.

  Ponter and Dern each took an end of the unexpanded Derkers tube. Adikor opened the door leading out to the computing floor. There was no equalizing hiss, no popping of ears; although the air in the computing chamber now presumably was mostly from the Gliksin world, comparable volumes had been exchanged. The Gliksins carefully filtered the air in the neutrino-detector facility, and the air Ponter was breathing now had no smell at all.

  The point of entry to the other universe was clearly marked by the two cables disappearing into a blue-limned hole in space. Dern, who had been on hand when Ponter was recovered the first time, maneuvered the tip of the collapsed Derkers tube so that it was in contact with the probe’s anchor cable. Ponter swung the length of the tube—a good eight armspans—and lined it up parallel to the anchor cable.

  “Ready?” asked Dern, looking over his shoulder at Ponter.

  Ponter nodded. “Ready.”

  “All right,” said Dern. “Gently now.”

  Dern began feeding the collapsed tube through the portal, which widened just enough to accommodate its narrow diameter. Ponter pushed gently from the rear. Adikor had brought a portable monitor with him, which was repeating the view from the probe. He angled the device so that Dern and Ponter could see what was happening on the other side. Although the probe had been lowered to the bottom of the neutrino detector chamber, so that the two cables attached to it took a downward turn as soon as they went through the portal, the Derkers tube was protruding parallel to the floor far below. The Gliksins couldn’t reach it; it was too far above their heads. But they were pointing at it, and shouting among themselves.

  “That’s far enough,” said Dern, noting that the tube was halfway through—he’d put a little reference mark at the appropriate spot along the tube’s length. Ponter stopped feeding more through. Dern came down to the tube’s end to help Ponter pull it open.

  At first, Ponter and Dern could each barely fit a hand into the narrow mouth of the tube. But the tube yielded as
they pulled in opposite directions, expanding its diameter more and more, its ratcheting mechanisms making loud clickings as it did so.

  Ponter got his other hand into the widened mouth, and Dern got his left hand in, too, and they continued to pull the mouth open. Soon, the tube was a good armspan in diameter—but that was only a third of its maximum extent, and they went on opening it wider and wider.

  Ambassador Prat and the three High Gray Councilors had come out onto the computing floor now. One of the Exhibitionists was with them; the other was standing at the topmost step leading up to the control room—he clearly wanted to be able to get away if something went wrong.

  Old Bedros looked like he wished to lend a hand—history was being made here, after all. Ponter nodded for him to go ahead. Soon, six hands were pulling at the tube’s widening mouth. On the portable monitor, Ponter could see the Gliksin’s strange pointed jaws dropping in astonishment.

  Finally, it was done: the tube had reached its maximum diameter, and its bottom was resting on the granite floor of the computing chamber. Ponter looked at Tukana, and gestured for her to go ahead. “You’re the ambassador,” he said.

  The gray-haired woman shook her head. “But they know you—a recognizable, friendly face.”

  Ponter nodded. “As you wish.” Adikor gave Ponter a great hug. Then Ponter moved back to the mouth of the tube, took a deep breath—despite what he’d seen through the probe’s eyes, he couldn’t help remembering what had happened to him the last time he’d gone through to the Gliksin world. He began to walk down the tube’s length. From the interior, the only sign of the portal was a faint blue ring of light visible through the translucent membrane spread between the crisscrossing metal components of the tube—it seemed that by forcing the portal wide open like this, they wouldn’t have to bear the disquieting sight of seeing cross sections of themselves as they passed through it.

  Ponter walked toward the blue ring, and then, with one giant step, moved across the threshold into Gliksin world. Through the tunnel’s opening, he could see the far wall of the neutrino-detector chamber, quite some distance away. It only took a few beats for him to make it to the very end of the tunnel, which, since Adikor and Dern were holding it steady at the other end, wasn’t dipping down much under Ponter’s weight.

  Ponter stuck his head out the end of the tube and looked down at the Gliksins far below, with what, he knew, must be a massive grin on his face. He spoke a few words, and Hak provided the translation in the loudest volume its external speaker could muster. “Would one of you be kind enough to fetch a ladder?”

  Chapter Ten

  There actually was a suitable ladder on Ponter’s side of the portal—but it would be very awkward to get it through the narrow confines of the computing center. So he waited while the Gliksins got one from the far side of the neutrino-detector chamber. It looked like the same ladder Ponter had climbed up when he’d come back home.

  It took a few tries, but finally the ladder was propped up against the open end of the Derkers tube protruding out of what Ponter knew must look to the Gliksins like thin air.

  Behind him, Ponter could see Dern and Adikor using power tools to affix their end of the Derkers tube to the granite floor of the quantum-computing chamber.

  Once the ladder was in place, Ponter retreated down the tube and let Adikor and Dern come along to where Ponter had been. They took a moment to stare out at the fascinating spectacle of the neutrino-detector chamber and the alien beings below, then got to work, struggling with ropes, lashing the ladder’s top to the mouth of the Derkers tube. Ponter could hear Adikor muttering, “Incredible, incredible,” over and over again as he worked.

  Adikor and Dern then returned to their side of the tube, and Ponter and Ambassador Prat walked its length. Ponter turned around and backed down the ladder, descending carefully to the neutrino-detector chamber’s floor. As he got close to the bottom, he felt Gliksin hands on his arms, helping him down. He got one foot then another onto the chamber’s floor, and turned around.

  “Welcome back!” said one of the Gliksins, his words translated into Ponter’s cochlear implants by Hak.

  “Thank you,” said Ponter. He looked at the faces surrounding him, but didn’t recognize anyone. That wasn’t surprising; even if they’d called someone he knew the moment they’d seen the probe, that person would still be in transit from the surface.

  Ponter moved away from the ladder and tipped his head up to look at the mouth of the tube. He waved at Ambassador Prat and shouted out, “Come on down!”

  The ambassador turned around and made her way down the ladder.

  “Hey, look!” said one of the Gliksins. “It’s a lady Neanderthal!”

  “She is Tukana Prat,” said Ponter. “Our ambassador to your world.”

  Tukana reached the ground and turned around. She slapped her hands together, removing the dust that had transferred to her palms from the ladder. A Gliksin—one of the two dark-skinned men—stepped forward. He looked rather at a loss for what to do, then, after a moment, he bowed at Tukana and said, “Welcome to Canada, ma’am.”

  The problem with relying on Hak for translations was that everything had to be filtered through its sense of humor. “We had planned to ask you to take us to your ladder,” said Hak, through his external speaker, “but I see you have already done that.”

  Ponter could follow enough of the Gliksin language to realize what was going on. He slapped his left forearm. “Ouch!” said Hak into Ponter’s cochlear implants. Then, through his speaker, he said, “Sorry. I mean, ‘Take us to your leader.’”

  The dark-skinned man who had stepped forward said, “Well, I’m Gus Hornby; I’m the head engineer here. And we’ve already called Doctor Mah in Ottawa—she’s SNO’s director. She could be here later today, if need be.”

  “Is Mare Vaughan around?” asked Ponter.

  “Mare? Oh—Mary. Professor Vaughan. No, she’s gone.”

  “Lou Benoît?”

  “You mean Louise? She’s gone, too.”

  “Reuben Montego, then.”

  “The doctor? Sure, we can get him down here.”

  “Actually,” said Ponter, with Hak translating, “we would prefer to go up to see him.”

  “Um, sure,” said Hornby. He looked up at the tunnel protruding from midair. “You’re assuming that will stay open?”

  Ponter nodded. “It is our hope.”

  “So you can just walk through to—to, um, to your side?” said one of the other Gliksins.

  “Yes.”

  “Can I go have a look?” asked the same Gliksin, who had light skin, orange hair, and sky-colored eyes.

  Ponter looked at Tukana, who looked back at him. Finally, Tukana said, “My government wishes to meet someone who can speak on behalf of your people.”

  “Oh,” said the orange-haired one. “Well, I can’t, really…”

  Ponter and Tukana walked across the bottom of the vast chamber, accompanied by the crowd of Gliksins. Pieces of the acrylic sphere that had once been in the center of this space were stacked against its circular walls, and countless sunflower-like photo multiplier assemblies were likewise gathered up.

  When they came to the far side of the chamber, there was another ladder, even taller than the one now reaching up to the Derkers tube. This ladder was used to access the entrance hatch for the neutrino-detector chamber, the same square hatch that had blown open when Ponter and all the air from the quantum-computing chamber had last transferred over. Hornby headed up the ladder first, then passed through the hatch. Tukana began her ascent.

  Ponter looked back at the tunnel that led to his world, and his heart jumped when he saw Adikor standing just inside its mouth looking down at him. Ponter thought about waving at him, but to do so would be too much like saying goodbye, and so he just smiled, although there was no way Adikor could see his expression over such a distance. That was probably all to the good, since the smile, Ponter knew, was forced. He took hold of the ladder’s sides and be
gan climbing up, hoping that this would not be the last time he’d ever see his beloved man-mate.

  Ponter shouldered his way through the opening, hauling himself to his feet. Suddenly, five Gliksins wearing identical green clothes moved toward him, each one carrying a large projectile-firing weapon.

  Ponter had read his share of speculative literature; he knew stories about parallel worlds, in which evil versions of people from the familiar universe existed. His first thought was that, somehow, he’d transferred to a different universe.

  “Mr. Boddit,” said one of the— soldiers, that was the word, wasn’t it? “My name is Lieutenant Donaldson, of the Canadian Forces. Please step away from the hatch.”

  Ponter did so, and Ambassador Prat emerged through the hatch, hoisting herself up onto the metal deck. The walls surrounding the deck were covered with dark green plastic sheeting, and conduits and plastic pipes hung from the ceiling. What looked like some form of computing equipment lined some of the walls.

  “Ma’am?” said Donaldson, looking at Tukana.

  Ponter spoke, and Hak translated. “This is Tukana Prat, our ambassador to your world.”

  “Ambassador, Mr. Boddit, I’ll have to ask both of you to come with me.”

  Ponter didn’t move. “Are we unwelcome here?”

  “Not at all,” said Donaldson. “Indeed, I’m sure our government will be happy to recognize the Ambassador, and grant you both full diplomatic courtesy. But for now, you must come with me.”

  Ponter frowned. “Where are you taking us?”

  Donaldson gestured toward the door leading out from the deck. It was currently closed. Ponter shrugged, and he and Tukana walked toward it. One of the other soldiers moved ahead and opened the door. They entered a cramped, narrow control room. “Keep moving ahead quickly, please,” said Donaldson.

  Ponter and Tukana did so. “As you may remember, Mr. Boddit,” said Donaldson, walking behind them, “the Sudbury Neutrino Observatory is located sixty-eight hundred feet below the ground, and is maintained in clean-room conditions, to prevent the introduction of any dust or other contaminants that might affect the detector equipment.”
