“The mine has been searched,” said Jasmel, flatly.
“The mine, yes, but—” Did he dare tell her? It sounded crazy when the words echoed inside his head; he could only imagine how insane they would seem when given voice. “We were working with parallel universes,” said Adikor. “It’s possible—remotely possible, I know, but I refuse to give up on him, on the man who is so very important to both you and me—that he has, well, slipped, somehow, into another of those universes.” He looked at her, imploring. “You must know something of your father’s work. Even if you made little time for him”—he saw those words cut deep—“he must have told you about our work, about his theories.”
Jasmel nodded. “He told me, yes.”
“Well, then, there might—just might—be a chance. But I need to get this reeking dooslarm basadlarm over with; I need to get back to work.”
Jasmel said nothing for a long time. Adikor knew from his own occasional arguments with her father that just letting her consider quietly would be more effective than pressing his point, but he couldn’t help himself. “Please, Jasmel. Please. It’s the only sensible wager to make: assume that I’m not guilty, and there’s a chance that we might get Ponter back. Assume that I am guilty, and he is surely gone for good.”
Jasmel was silent a while longer, then: “What do you want from me?”
Adikor blinked. “I, ah, I should have thought it was obvious,” he said. “I want you to speak on my behalf at the dooslarm basadlarm.”
“Me?” exclaimed Jasmel. “But I’m one of those accusing you of murder!”
Adikor held up his left wrist. “I’ve carefully reviewed the documents I was given. My accuser is your mother’s woman-mate, Daklar Bolbay, acting on behalf of your mother’s children: you, and Megameg Bek.”
“Exactly.”
“But she cannot act on your behalf. You’ve seen 250 moons now; you’re an adult. Yes, you can’t vote yet—neither can I, of course—but you are responsible for yourself. Daklar is still the tabant of young Megameg, but not of you.”
Jasmel frowned. “I—I hadn’t thought of that. I’ve gotten so used to Daklar looking after my sister and me …”
“You are your own person under the law now. And no one could better persuade an adjudicator that I did not murder Ponter than his own daughter.”
Jasmel closed her eyes, took a deep breath, and let it out slowly in a long, shuddery sigh. “All right,” she said at last. “All right. If there’s a chance, any chance at all, that my father still lives, I have to pursue it. I have to.” She nodded once. “Yes, I’ll be the one to speak on your behalf.”
Chapter 14
The conference room at the Creighton Mine had wall diagrams showing the network of tunnels and drifts. A hunk of nickel ore sat as a centerpiece on a long wooden table. A Canadian flag stood at one end of the room; the other had a large window overlooking the parking lot and the rough countryside beyond.
At the head of the table was Bonnie Jean Mah—a white woman with lots of brown hair who was married to a Chinese-Canadian, hence her last name. She was the director of the Sudbury Neutrino Observatory, and had just flown in from Ottawa.
Along one side of the table sat Louise Benoit, the tall, beautiful postdoc who’d been down in the SNO control room when the disaster had occurred. And on the other side sat Scott Naylor, an engineer from the company that had manufactured the acrylic sphere at the heart of SNO. Next to him was Albert Shawwanossoway, Inco’s top expert on rock mechanics.
“All right,” said Bonnie Jean. “Just to bring everyone up to date, they’ve started draining the SNO chamber, before the heavy water gets any more polluted. AECL is going to try to separate the heavy water from the regular water, and, in theory, we should be able to reassemble the sphere and load it up with the recovered heavy water, getting SNO back on-line.” She looked at the faces in the room. “But I’d still like to know exactly what caused the accident.”
Naylor, a balding, tubby white man, said, “I’d say the sphere containing the heavy water burst apart because of pressure from the inside.”
“Could the displacement caused by a man entering the sphere have done that?” asked Bonnie Jean.
Naylor shook his head. “The sphere held 1,100 tonnes of heavy water; you add a human being, weighing a hundred kilos—one-tenth of a tonne—and you’ve only increased the mass by one ten-thousandth. Human beings have about the same density as water, so the displacement increase would only be about one ten-thousandth, as well. The acrylic could easily handle that.”
“Then he must have used an explosive of some sort,” said Shawwanossoway, an Ojibwa of about fifty, with long, black hair.
Naylor shook his head. “We’ve done assays on the water recovered from the tank. There’s no evidence of any explosive—and there aren’t that many that would work soaking wet, anyway.”
“Then what?” asked Bonnie Jean. “Could there have been, I don’t know, a magma incursion or something, and the water boiled?”
Shawwanossoway shook his head. “The temperature of SNO, and the whole mine complex, is closely monitored; there was no change. In the observatory cavern, it held steady at its normal value of 105 degrees—Fahrenheit, that is; forty-one Celsius. Hot, but nowhere near boiling. Remember, too, that the mine is a mile and a quarter underground, meaning the air pressure is about thirteen hundred millibars—30 percent above that at sea level. And at higher pressures, of course, the boiling point goes up, not down.”
“What about the flip side?” asked Bonnie Jean. “What if the heavy water froze?”
“Well, it would indeed have expanded, just like regular water,” said Naylor. He frowned. “Yes, that would have burst the sphere. But heavy water freezes at 3.82 Celsius. It just couldn’t possibly get that cold that far down.”
Louise Benoit joined the conversation. “What if more than just the man entered the sphere? How much material would have to be added before it would burst?”
Naylor thought for a moment. “I’m not sure; it was never specced for that. We always knew exactly how much heavy water AECL was going to loan us.” He paused. “Maybe … I don’t know, maybe 10 percent. A hundred cubic meters, or so.”
“Which is what?” asked Louise. She looked around the conference room. “This room’s about six meters on a side, isn’t it?”
“Twenty feet?” said Naylor. “Yeah, I guess.”
“And it’s got ten-foot ceilings—that’s three meters,” continued Louise. “So you’re talking about a volume of material as big as the contents of this room.”
“More or less, I suppose.”
“That’s ridiculous, Louise,” said Bonnie Jean. “All you found down there was one man.”
Louise nodded, conceding that, but then she lifted her arched eyebrows. “What about air? What if a hundred cubic meters of air were pumped into the sphere?”
Naylor nodded. “I’d thought about that. I thought maybe a belch of gas had somehow welled up into the sphere, although how it would get inside I have no idea. The water samples we took were somewhat aerated, but …”
“But what?” asked Louise,
“Well, they were indeed aerated, with nitrogen, oxygen, and some CO2, as well as some gabbroic rock dust and pollen. In other words, just regular mine air.”
“Then it couldn’t have come from the SNO facility,” said Bonnie Jean.
“That’s right, ma’am,” said Naylor. “That air is all filtered; it’s free of rock dust and other pollutants.”
“But the only parts of the mine connecting to the detector chamber are in the SNO facility,” said Louise.
