She nodded, and spoke some more commands, transferring various documents into local storage.
"All right,” I said. “My fee is two hundred solars an hour."
"That's fine, that's fine, of course! I don't care about the money, Mr. Lomax—not at all. I just want
Joshua back. Please tell me you'll find him."
"I will,” I said, smiling my most reassuring smile. “Don't you worry about that. He can't have gone far."

Actually, of course, Joshua Wilkins could perhaps have gone quite far—so my first order of business
was to eliminate that possibility.
No spaceships had left Mars in the last ten days, so he couldn't be off-planet. There was a giant airlock
in the south through which large spaceships could be brought inside for dry-dock work, but it hadn't been
cracked open in weeks. And, although a transfer could exist freely on the Martian surface, there were
only four personnel air locks leading out of the dome, and they all had security guards. I visited each of
those air locks and checked, just to be sure, but the only people who had gone out in the last three days
were the usual crowds of hapless fossil hunters, and every one of them had returned when the dust storm
began.
I remember when this town had started up: “The Great Fossil Rush,” they called it. Weingarten and
O'Reilly, two early private explorers who had come here at their own expense, had found the first fossils
on Mars, and had made a fortune selling them back on Earth. More valuable than any precious metal;
rarer than anything else in the solar system—actual evidence of extraterrestrial life! Good fist-sized
specimens went for millions in online auctions; excellent football-sized ones for billions. There was no
greater status symbol than to own the petrified remains of a Martian pentaped or rhizomorph.
Of course, Weingarten and O'Reilly wouldn't say precisely where they'd found their specimens, but it had
been easy enough to prove that their spaceship had landed here, in the Isidis Planitia basin. Other
treasure hunters started coming, and New Klondike—the one and only town on Mars—was born.
Native life was never widely dispersed on Mars; the single ecosystem that had ever existed here seemed
to have been confined to an area not much bigger than Rhode Island. Some of the prospectors—excuse
me, fossil hunters—who came shortly after W&O's first expedition found a few nice specimens, although
most had been badly blasted by blowing sand.
Somewhere, though, was the mother lode: a bed that produced fossils more finely preserved than even
those from Earth's famed Burgess Shale. Weingarten and O'Reilly had known where it was—they'd
stumbled on it by pure dumb luck, apparently. But they'd both been killed when their heat shield
separated from their lander when re-entering Earth's atmosphere after their third expedition here—and, in
the twenty mears since, no one had yet rediscovered it.
People were still looking, of course. There'd always been a market for transferring consciousness; the
potentially infinite lifespan was hugely appealing. But here on Mars, the demand was particularly brisk,
since artificial bodies could spend days or even weeks on the surface, searching for paleontological gold,
without worrying about running out of air. Of course, a serious sandstorm could blast the synthetic flesh
from metal bones, and scour those bones until they were whittled to nothing; that's why no one was
outside right now.
Anyway, Joshua-never-Josh Wilkins was clearly not outside the dome, and he hadn't taken off in a
spaceship. Wherever he was hiding, it was somewhere in New Klondike. I can't say he was breathing
the same air I was, because he wasn't breathing at all. But he was here, somewhere. All I had to do was
