it's basaltic?"
    "I've noticed it's plain."
    "Exactly," said Lewis, now the lecturer. In geology he wasn't the fingie. "Compared to many of the metallic meteorites, this looks boring to us. Ordinary. That's because it's a common kind of rock found on earth but a rare kind to come from space. Most meteorites have more iron and nickel. They date from the dawn of the solar system. This one came later in history, after the place of its origin had experienced some kind of heating and melting and igneous rock had formed, like the earth's crust."
    Moss was nodding. He was eager for confirmation.
    "That suggests it didn't come from the usual source like asteroids or comets," Lewis went on. "It probably came from the moon. Or Mars. Blasted into space eons ago after a bigger meteorite, maybe a mile across, slammed into the red planet. Ejected and captured by earth's gravity like the one they found in the Allan Hills, the famous one they thought might have fossil evidence of Martian microbes."
    Moss allowed himself a hint of eagerness. "Could this one have fossils inside?"
    "There's been no agreement they exist in the other one. But this kind of meteorite is rare and even the remotest possibility makes it pretty valuable. We can't be sure what this is at all, of course- not with me. I don't have the instruments and I don't have the expertise. The way they confirmed things in Houston was by analyzing ancient gas trapped in the meteorite and finding it matched the Martian atmosphere."
    "It may not be Martian at all," Moss allowed. He wanted more hope.
    "No. Only sixteen have been found worldwide. But… it looks possible to me," Lewis gave him. "An achondrite, the kind of meteorite that would come from a planet or the moon. Sparco says you have a spectroscope down here and I brought some stuff to reduce a sample for a gas-spectrum analysis. I can also slice a small cross section and look at its composition under the microscope. I'll test for oxygen and oxidized iron isotopes. Check its magnetism, which indicates how much ferric iron. If it's a simple plagioclasepyroxene basalt, or maybe olivine, it will be promising. Radioactive dating of a young age will persuade even more. We'll need some photos and a statement to authenticate its place of origin. And then you take it to Houston, or wherever."
    Moss nodded, watching him. "Yes. Wherever." He hesitated. "Jim told me I could trust another question to you."
    Lewis had been waiting for this. "Its commercial value?" This opinion was Sparco's price for his being allowed to come down here. He was to assess, and then keep his mouth shut. He'd wanted purpose, and this was his ticket.
    "As another measure of its importance."
    "Private collection of scientific artifacts is booming," Lewis said. "Having a living-room museum has become cool among the ultrarich. The mere possibility this could be from Mars will be enough for some buyers. The chance it could hold evidence of extraterrestrial life trumps all. That rock could be worth a lot of money."
    "How much money?"
    Lewis had researched this. "Pieces of Mars have sold for twenty-five hundred dollars a gram."
    "Which makes this rock worth…"
    "Several million dollars."
    Moss nodded solemnly.
    "Pieces of the moon are even rarer and have fetched ten times that. The Apollo rocks turned out to be from a concentrated region of unusually high radioactivity, so lunar meteorites tell us more about the moon than what the astronauts brought back. They've fetched twenty-five hundred times the price of gold."
    "Astonishing," Moss said. He didn't seem very astonished.
    "But everything here is the property of the American government, right?"
    "If they know about it," the scientist said, looking evenly at Lewis.
    "It's an American base. American taxpayer dollars." No one was allowed to hunt for souvenirs in Antarctica, Lewis knew. They told you that up front.
    "Is it?" Moss asked. "To you, just stepping off the plane, looking at that ragged flag, I suppose it is.
