Any good snoop watches his back, doing countersurveillance to be sure his opponents aren’t catching on to his efforts. The entire time I had been using Colorado Supernet—for eight months, ever since my arrival in Denver—I had been electronically looking over the system administrators’ shoulders to make sure they hadn’t caught on to the way I was using their servers as a massive free storage locker, as well as a launchpad into other systems. That involved observing them at work; sometimes I’d simply log on to the terminal server they used and monitor their online sessions over the span of a couple of hours or so. And I was also checking that they weren’t watching any of the other accounts I was using.
