This bank of the river—the right bank—was impassable beyond this point, because of Baron’s Rock, which turned the shore into a vertical stone wall scoured by icy water in violent motion. To get to Elphinstone she would have to cross to the left bank by running across the dam, following the road that ran over its top. From there she’d have twenty miles of bad road between her and Elphinstone. Jahandar—she was pretty sure that the fast-running jihadist was he—was only a short distance behind her at this point, and was running faster. If she merely followed the road, he could drop her with a rifle shot, or simply catch up with her and put a knife in her back.
