another, those from Talok’s; the lower-left, pictures of Gawlt’s life; and the lower-right, images of Lulasm’s. Adikor, Ponter knew, was a Hawst fan, so he told the Voyeur to expand that image to fill the entire screen. Ponter had to admit that Hawst was always up to something interesting—this morning, he’d headed to the outskirts of Saldak where five people had been buried alive by a rockslide. Still, if an Exhibitionist did come by the mineshaft entrance today, Ponter hoped it would be Lulasm; Ponter thought she usually asked the most insightful questions.
    Ponter and Adikor both sat and put on dining gloves. Adikor scooped up some pine nuts from the bowl and sprinkled them over his steak, then pounded them into the meat with the palm of his gloved hand. Ponter smiled; it was one of Adikor’s endearing quirks—he’d never met anyone else who did that.
    Ponter picked up his own steak, still sizzling slightly, and bit a hunk off. It had that sharp tang one only tasted in meat that had never been frozen; how had anyone survived before vacuum storage had been invented?
    A short time later, Ponter saw the hover-bus settle to the ground outside the house. He told the Voyeur to shut off, they tossed their dining gloves in the sonic cleanser, Ponter patted Pabo on the head, and he and Adikor went out the door, leaving it open so that Pabo could come and go as she pleased. They entered the hover-bus, greeting the seven other passengers already on board, and headed off to work as if it were just another ordinary day.

Chapter 4
    Ponter Boddit had grown up in this part of the world; he’d been aware of the nickel mine his whole life. Still, he’d never met anyone who had visited its depths; the mining was done exclusively by robots. But when Klast had been diagnosed with leukemia, Ponter and she had begun to meet with others suffering from cancers—for support, for companionship, and to share information. They met in a kobalant facility, which, of course, was vacant in the evenings.
    Ponter had expected several of the others who were afflicted to have visited the mine. After all, by going deep in the rocks, they surely would have been exposed to abnormally high radioactivity.
    But no one who had gone down into the mine was part of their group. Ponter started asking around and discovered that this was a very unusual nickel mine; the background radiation levels in its ancient granites were extraordinarily low.
    And, because of that, an idea occurred to him. He was a physicist, working with Adikor Huld on building quantum computers. But the quantum registers were enormously sensitive to outside disturbances; they’d had a real problem with cosmic rays provoking decoherence.
    The solution, it seemed, was right beneath their feet. With a thousand armspans of rock over their heads, cosmic rays would no longer pose a problem. At that depth, nothing short of neutrinos could penetrate, and they wouldn’t affect the experiments Ponter and Adikor wanted to run.
    Delag Bowst was Saldak’s chief administrator; the position had been forced upon him by the Grays. But, of course, it was always that way with administrators: no one who would choose such a contribution was suited to make it
    Ponter had presented his proposal to Bowst: let him build a quantum-computing facility deep inside the mine. And Bowst had convinced the Grays to agree. A technological civilization could not exist without metals, after all, but the mine had not always been friendly to the environment. Any opportunity to do something positive was welcomed.
    And so the computing facility had been built. Ponter and Adikor were still having problems with an unexpected source of decoherence: piezoelectric discharges caused by the stresses on the rocks at such great depths. But Adikor felt he’d now solved that problem, and today they would try again, factoring a number bigger than any ever done before.
    The hover-bus dropped Ponter and Adikor off at the entrance to
