felt a chill emanating from Kohler’s crippled form. “Who else knew about this?” he asked.
    “No one,” Vittoria said. “I told you that.”
    “Then why do you think your father was killed?”
    Vittoria’s muscles tightened. “I have no idea. He had enemies here at CERN, you know that, but it couldn’t have had anything to do with antimatter. We swore to each other to keep it between us for another few months, until we were ready.”
    “And you’re certain your father kept his vow of silence?”
    Now Vittoria was getting mad. “My father has kept tougher vows than that!”
    “And you told no one?”
    “Of course not!”
    Kohler exhaled. He paused, as though choosing his next words carefully. “Suppose someone did find out. And suppose someone gained access to this lab. What do you imagine they would be after? Did your father have notes down here? Documentation of his processes?”
    “Director, I’ve been patient. I need some answers now. You keep talking about a break-in, but you saw the retina scan. My father has been vigilant about secrecy and security.”
    “Humor me,” Kohler snapped, startling her. “What would be missing?”
    “I have no idea.” Vittoria angrily scanned the lab. All the antimatter specimens were accounted for. Her father’s work area looked in order. “Nobody came in here,” she declared. “Everything up here looks fine.”
    Kohler looked surprised. “ Up here?”
    Vittoria had said it instinctively. “Yes, here in the upper lab.”
    “You’re using the lower lab too?”
    “For storage.”
    Kohler rolled toward her, coughing again. “You’re using the Haz-Mat chamber for storage? Storage of what? ”
    Hazardous material, what else! Vittoria was losing her patience. “Antimatter.”
    Kohler lifted himself on the arms of his chair. “There are other specimens? Why the hell didn’t you tell me!”
    “I just did,” Vittoria fired back. “And you’ve barely given me a chance!”
    “We need to check those specimens,” Kohler said. “Now.”
    “Specimen,” Vittoria corrected. “Singular. And it’s fine. Nobody could ever—”
    “Only one?” Kohler hesitated. “Why isn’t it up here?”
    “My father wanted it below the bedrock as a precaution. It’s larger than the others.”
    The look of alarm that shot between Kohler and Langdon was not lost on Vittoria. Kohler rolled toward her again. “You created a specimen larger than five hundred nanograms?”
    “A necessity,” Vittoria defended. “We had to prove the input/yield threshold could be safely crossed.”
    The question with new fuel sources, she knew, was always one of input vs. yield—how much money one had to expend to harvest the fuel. Building an oil rig to yield a single barrel of oil was a losing endeavor. However, if that same rig, with minimal added expense, could deliver millions of barrels, then you were in business. Antimatter was the same way. Firing up sixteen miles of electromagnets to create a tiny specimen of antimatter expended more energy than the resulting antimatter contained. In order to prove antimatter efficient and viable, one had to create specimens of a larger magnitude. Although Vittoria’s father had been hesitant to create a large specimen, Vittoria had pushed him hard. She argued that in order for antimatter to be taken seriously, she and her father had to prove two things. First, that cost-effective amounts could be produced. And second, that the specimens could be safely stored. In the end she had won, and her father had acquiesced against his better judgment. Not, however, without some firm guidelines regarding secrecy and access. The antimatter, her father had insisted, would be stored in Haz-Mat—a small granite hollow, an additional seventy-five feet below ground. The specimen would be their secret. And only the two of them would have access.
    “Vittoria?” Kohler insisted, his voice tense. “How large a specimen did you and your father create?”
    Vittoria
