This wasn’t like crossing a stretched steel cable in a military training camp. The bundle was a skein of perhaps two dozen separate wires, as gaily colored as a maypole. Some of the wires were electrical, some telephone, some data, some not clearly identifiable. He couldn’t get his hand around the whole bundle, and so every time he swung forward he had to thrust his fingertips like a blade into the heart of the thing and get a grip on whatever presented itself. This had worked the first few times, but on his last grab he had aimed wrong, missed the bundle, and snatched one single wire, a blue Ethernet cable that spiraled around all the other wires, and now his weight was pulling all the slack out of that one wire and peeling it loose from the bundle. He reached up with his free hand, whipped it around the taut blue line, and pulled himself up enough to get that first hand free, then repeated, ascending the wire but not gaining altitude since the blue wire was still giving up slack. He was only an arm’s length below the bundle but couldn’t quite reach it. Finally the wire stopped giving way and held fast and he kicked up with his legs, making himself upside down for a moment, and got both legs wrapped around the whole bundle. The rifle, and a CamelBak water pouch that he was wearing on his back, fell to the ends of their straps and dangled. He allowed himself a few seconds to catch his breath before he began shinnying along the bundle as rapidly as he could manage. This was much slower than the hand-over-hand technique and made him feel like an incompetent civilian, but he could not risk doing it the other way. In any case, he was not too worried about being shot at since the apartment was now completely engulfed in flames. Solvent cans burst open and vomited storms of combustible vapor from windows.
