He finally found Gray in a MarsPrep camp just over the Bolivian border and into Peru, hiding behind some cheap facial surgery and the name Rodriguez. It wasn’t a bad cover in itself, and it probably would have stood standard scrutiny. Security checks in the prep camps were notoriously lax; the truth was that they didn’t much care who you’d been before you signed up. But there were still a few obvious signs you could look for if you knew how, and Carl, with a methodical intensity that was starting to resemble desperation, had been looking for weeks. He knew that Gray was up on the altiplano somewhere, because the trail led there from Bogotб, and because where else, ultimately, was a variant thirteen going to run. He knew this, and he knew it was just a matter of time before the traces showed up and someone called it in. But he also knew, with induction programs everywhere skimping and speeding up to meet increasing demand, that time was on the other man’s side. Something had to give, and soon, or Gray was going to be gone and Carl wasn’t going to get his bounty.

So when the break came, the tiny morsel of data finally fed back from the web of contacts he’d been plying all those weeks, it was hard not to jump. Hard not to dump his painstakingly constructed cover, fire up his Agency credit and badge, and hire the fastest set of all-terrain wheels available in Copacabana. Hard not to tear across the border at Agency speed, raising road dust and rumors all the way to the camp, where Gray, of course, if he had any kind of local support, would be long gone.
